LG G4 review

The LG G4 has arrived, complete with a leather back, boosted camera, screen and specifications

Different people want different things from their smartphones. Some place appearance and design above all else. Others want the very fastest performance. A fair chunk, however, value the practical things in life, and it's these people who will be looking closest at the LG G4.

Of all the leading smartphones launched in 2015, the LG G4 is the only one with both a microSD card and a removable battery.




The LG G4’s design, certainly in terms of its basic shape and the placement of the controls, breaks no new ground. The rear is still gently curved and fits in your hand nicely. The volume and power buttons still reside in the centre of the rear panel, just below the camera lens.



The overall dimensions haven’t changed much either. The LG G4 is slightly taller and slightly wider than the G3 at 149 x 75 x 8.9mm, but these are not differences you’ll notice with the naked eye.

Turn it on its side, however, and the changes begin to reveal themselves. First, the G4 sports a “Slim Arc” screen that gently curves from top to bottom, a bit like LG's G Flex models, but the curve isn’t quite so extreme.



The most dramatic new ‘feature’ introduced by LG, perhaps inspired by the Motorola Moto X (2014), is to the materials used in the design. You will, perhaps, have already seen the brown, leather-backed edition in the teaser material released by the company.



Well, that’s a standard (albeit premium) finish on the G4, and it isn’t just available in brown. There’s a whole range of different colours, all of which look very fetching, with precise, close stitching running down the centre and the G4 logo debossed into the leather in the bottom right corner.

There's even differentiation in the type of leather used, depending on the colour, with a smooth, close-grained briefcase finish on the brown and burgundy versions, and a coarser more open grained leather used on the pale blue, black, and light tan models.

The LG G4 also comes, slightly less interestingly, in plastic in a fetching range of shades including a glossy, "ceramic" white and titanium grey, with a subtle diamond pattern moulded into the shell.

We suspect most people choosing an LG G4 will go for the leather finish, which feels very nice indeed in the hand and looks great; the black version in particular is fabulous.



It wouldn't be a flagship launch without a specifications bump, so it's hardly a surprise to see an improvement on that front. But at least LG is doing things differently from the majority of the competition, utilising Qualcomm's six-core, 64-bit 1.8GHz Snapdragon 808 SoC, which is backed by an Adreno 418 GPU, 3GB of RAM and 32GB of storage.

Other specs include dual-band, dual-stream 802.11ac Wi-Fi with support for MU-MIMO, Cat9 4G with download speeds of up to 450Mbits/sec, Bluetooth 4.1 and NFC. What you don't get is any kind of waterproofing or wireless charging as standard, although you can add the latter via an optional replacement back.



Those six cores are split in a dual-core/quad-core arrangement, running at frequencies of 1.8GHz and 1.44GHz respectively. On paper, and in testing, this delivers a mixed bag of results.

The results compare surprisingly well with the Snapdragon 810 in the HTC One M9, despite the fact that the G4 uses half the number of cores as the 810 for intensive tasks. It lags behind the Samsung’s Exynos 7420 processor, however, which is faster across the board, and it’s slower than both phones in the GFXBench gaming test. Do bear in mind, though, that the HTC One M9 has a lower resolution 1080p display which is far easier to drive than the G4's 1,440 x 2,560 screen.

Of the three big phones launched this year, then, the G4 is the slowest; that's not to say this is a problem, though. Indeed, the LG G4 feels perfectly responsive in daily use, and we haven’t yet found a game that fazes it.

Elsewhere, battery life is an improvement on last year’s G3, both in terms of its capacity and according to the results from our tests. Streaming a 720p video in flight mode with the screen set to a brightness of 120cd/m2 drained it at 6.3% per hour while audio streaming over 4G drained it at 3.6%.

That can’t quite match the Samsung Galaxy S6’s figures of 5.5% and 3%, but it's better than the MTC One M9 (9.7% and 2.6%), and with a user-replaceable battery, it's more flexible than both.

LG credits the phone’s improved efficiency to a number of changes, not least a more efficient screen. The G4 uses what LG calls “N-type liquid crystals”, which it says allows the light from the screen’s backlight through the structure of the liquid crystal more easily.

Reading between the lines, the benefit here isn’t intended to be extra brightness - the LG G4’s top brightness of 476cd/m2 is far from most eye-searing we’ve measured - rather the reduction the amount of power needed to power the display to that sort of brightness in the first place.



One of LG’s other claims is that the screen is capable of producing a wider range of colours than other phones, in accordance with the DCI (digital cinema initiatives) standard, rather than sRGB or Adobe RGB. In practice, we found the G4 covers 97.9% of the sRGB colour gamut, which is highly impressive in itself, while producing a richer tapestry of greens and reds.

Colour accuracy, however, is tougher to assess, since even with the automatic brightness adjustment turned off, the display still adjusts the intensity of the backlight depending on what’s displayed onscreen. To the eye, though, the LG G4’s display has plenty of impact, is as crisp as anyone needs, and the colours really leap from the screen.
LG G4 review: cameras

Smartphone cameras have been really moving on of late, and LG appears to be keeping pace here, upping the resolution to 16-megapixels from the G3's 13-megapixels, and the aperture to f/1.8, outdoing the f/1.9 aperture on the Samsung Galaxy S6’s rear camera in the process.

What this boils down to is there’s more light hitting the sensor. More light means you can use faster shutter speeds and/or lower ISO sensitivity settings. And that means sharper pictures that are lower in noise.







LG doesn’t stop there, though. It has also improved the optical image stabilisation system as well, adding “Z-axis feedback” this time around and the laser-assisted autofocus remains in place from the G3, helping the camera produce sharp photos quickly, not to mention a new "colour spectrum sensor”, which is used to set white balance and flash temperature correctly.

With near identical core specifications to the Samsung Galaxy S6 and S6 Edge's camera (16MP, f/1.9, 1/2.6in sensor, OIS, phase detect autofocus), the G4 ought to deliver a decent quality snap, and that it certainly does. In daylight, photos are crisp and well-exposed - the autofocus system really helps when shooting from the hip, and in terms of general quality it’s a match of the Samsung phone.

In low light the G4’s camera beats the S6’s in some respects, delivering a sharper, less noisy image, but in testing the LG didn’t always choose the correct white balance. Under fluorescent strip lights, for instance, white and light grey shades were tinged with yellow. So much for the colour spectrum sensor.

If you use the phone’s impressive manual mode, however, and set the G4 to shoot in raw (DNG format) and JPEG, you’ll be able to rescue those images, as well as maintain fine control over shutter speed, white balance, ISO sensitivity, exposure compensation and focus. There’s even an auto-exposure lock facility. It’s just a pity that LG doesn’t extend this level of control to video capture, which remains auto-only.



The front camera, as is the current trend, is now a high-resolution 8-megapixel unit, and there’s a host of enhancements to the camera software. You can now double tap the power button when the phone is in standby to launch the camera quickly.

There’s also a rather gimmicky, fairly pointless “gesture interval shot” selfie mode, which, simply put, lets you take a sequence of shots two seconds apart by opening your hand and clenching your fist in front of the camera a couple of times.

Naturally, there’s also the usual raft of improvements to LG’s UI overlay, which runs on a base of Android 5.1, but none appear to be particularly groundbreaking. Owners of new-ish Volkswagens, will appreciate the addition of support for its MirrorLink entertainment and navigation system, and you also get 100GB of Google Drive space, free for two years.



It’s hard to be different in the smartphone world, but LG has pulled it off with its attractive leather-backed G4 flagship.

Critically, it hasn’t compromised on performance, battery life or camera quality, and by retaining both a microSD slot and a removable battery, the G4 will appeal to a whole tranche of customers to whom flexibility is most important.

It’s too early to give the LG G4 a rating just yet because there are no prices for the leather options yet nor contract prices for any G4. The only price right now is for the plastic, SIM-free G4 from Amazon, which is £530.

However, assuming the leather phone comes in £30 to £50 more expensive, it’s still cheaper than a Samsung Galaxy S6, and that may yet tip the balance in the LG G4’s favour.

Gadgets to Keep You Moving at Work


The problem is, sitting at a computer for eight-plus hours a day, and maybe a few more at night, isn't exactly conducive to the "elite fitness" ideal promoted in a lot of exercise programs. Hell, according to some, just sitting down too much is killing us; it's been equated with smoking (even the cancer part!). There's no question a sedentary life is going to get more people headed toward heart disease. This infographic spells out some of the problems.

But you've got work to do! How can you do both? Check out the products on the next few pages for options, small to large, cheap to oh-sweet-lord expensive. Adding any of them at all to your daily regime of sitting and staring at a screen will go a long way to helping you live a little longer. In fact, research shows just an hour of exercise a day can offset the ill effects of your bum in cushion the rest of the time. So get ready to get fit.

Gyroscopic Wrist and Forearm Exerciser



It might look like nothing more than a hard plastic ball with another weird ball inside it. But these exercisers, available on Amazon from makers like NSD Power and DFX Sports, get your arms toned while also helping fix repetitive stress injuries like tennis elbow or wrist tendonitis. Using a pull-string or a dock to get the interior ball spinning, you then keep it going with your arm and wrist. If you can't grasp the concept, just search on "powerball gyroscope" on YouTube for plenty of examples. Different models have different abilities; some generate lights inside, while others have exterior LCD counters so you can visualize your reps. Prices go from $20 to $55, depending on the bells and whistles.

Theraband FlexBar


A foot-long bar of natural rubber might not sound like much of a workout tool. But bend the FlexBar in half a few times and you'll find the resistance undeniable. Of course it's got a great grip and bounces back into shape. It comes in yellow, red, green, or blue, each at a different diameter (from 1 3/8th up to 2 inches). The thicker the bar, the more pounds of force it takes to bend (from 6 up to 25 pounds). Prices go from $21.99 to $35.49, or get all four for $73.49.

Intel's Compute Stick?

What do you do with a PC on a stick?
Intel  PC Compute Stick


Intel's Compute Stick delivering a full Windows 8.1-compatible PC on an HDMI stick for $150. It has an Intel processor, 32GB of storage, Bluetooth, Wi-Fi, and a USB port, and it can just plug into any screen and turn it into a PC. Cool, right? It's part of a new revolution in computing, which is turning every screen into a computer. We're just not sure why.

The Compute Stick becomes available right after Google announced its Chromebit, which does the same thing but with Chrome OS. And bubbling under these slicker consumer products, for a while, has been a whole world of semi-functional Android-powered sticks, usually with cheap Rockchip processors.

The whole category is a bit of a side effect, a knock-on from the development of smartphone technology. All of the parts here are smartphone parts. The companies have just removed the cellular radios, and with them the need to deal with annoying, controlling mobile-phone companies and federal regulators.

We're Fighting the Law...

The obvious challenge that most of these products are trying to solve is that people want more Internet content on their TVs. We want to stream all of that stuff that we know is out there, and thus be able to break free from overpriced cable TV bundles. Smart TV interfaces are awful, and a lot of content is restricted from streaming on TVs because of incomprehensible licensing restrictions that make no sense to normal humans. So the PC sticks, intitially, will become ways for people to watch what they want to watch on TV.

There's an advantage to having a full PC even there, by the way. Roku, Amazon, and their ilk all still sign up for the miserable mesh of licensing agreements, which means that you can watch things on your laptop but sometimes not on a PC. Hooking up a PC to your TV lets you get around all that nonsense.

Unfortunately, as soon as you start trying to solve that problem, you earn some powerful enemies. The TV studios, cable companies, and content owners don't want you to break their rules, absurd as they may seem. Individuals can generally survive in the gray areas of streaming what isn't formally permitted, but isn't officially forbidden, but any real company that tries to improve access to content without cutting the existing players in will get slapped down.

A PC on Every Billboard That leads to the second problem. Home theater PCs and Android-powered TV sticks have existed for years, but they've never broken through to the mainstream because their setup and interfaces just aren't simple enough for non-technical users. That's because professional developers shy away from working on this problem out of fear of getting sued by content companies. That leaves development to individual hackers and open-source projects, which aren't known for creating interfaces that the non-technical can really enjoy.

So let's look at other uses. The sticks could do amazing work as digital signage for businesses, but that isn't going to get consumers' blood flowing. Dell and others have been plugging sticks as a thin-client solution for enterprises, but they haven't been taking off in a big way. As a primary computer, I don't see the advantage of these sticks over a cheap laptop, especially after you have to pay for a monitor, keyboard, and mouse.

Take off, land or instantly pause your flight midair with a single touch. Click to start and stop recording or snap a photo, even adjust camera angle while you fly. In case you missed it in the picture…that’s a high-quality HDMI port directly from the controller so you can connect Solo to practically any screen you can think of. By working directly with GoPro,

The new 3-axis gimbal delivers fluid HD video to your mobile device, offers in-flight recording control and access to GoPro settings—and oh yeah, it powers your GoPro, too.

Motorola Moto E (2015, Boost Mobile)


For $99.99 on Boost Mobile, the Motorola Moto E is an exceptional value that should be the first option for price-conscious smartphone buyers. Display quality is on point, performance is solid, and the Moto E supports 4G LTE connectivity. Throw in near-stock Android software and a promise of speedy updates, and you have a real winner on your hands. The Moto E easily earns our Editors' Choice award for budget smartphones on Boost.





Network Performance and Battery Life

Boost piggybacks on Sprint's 3G CDMA and 4G LTE networks, and the Moto E supports all the appropriate network frequencies. We've seen Sprint's Spark LTE network deliver seriously fast speeds, but finding coverage is the real issue here. In my tests, the Moto E hovered around 5Mbps down and 1Mbps up, but our LTE coverage was pretty spotty. Call quality was good, with strong earpiece volume and clear transmissions through the mic. Noise cancellation worked well, but also dampened natural voice tones, making them sound somewhat digitized.

Software and Conclusions

Motorola is building a great reputation for clean Android software and timely updates. The Moto E runs an essentially stock version of Android 5.0, which is incredibly rare in the low-end market. Boost, unfortunately, loads up a healthy serving of bloatware, but most of it is uninstallable. Mobile ID, for Sprint's theming service, and Boost Zone, for account management, are both permanent additions, but more offensive apps like Boost Wallet and NBA Game Time can be easily removed.

Of the 8GB of internal storage, 4.55GB is available to users out of the box. Our 64GB microSD card worked fine as well. The built-in storage is key for larger apps, and the Moto E easily beats phones like the LG Tribute, which tops out at a paltry 1.4GB of storage.

The Motorola Moto E stands as a litmus test for the ultra-budget smartphone market. The high-quality parts and clean Android software make for a potent combination, especially in the sub-$100 realm. It's an easy pick for a budget-friendly Editors' Choice on Boost. You could opt for the LG Tribute and save $20; it performs similarly, but doesn't have nearly as much internal storage capacity. Those looking for a bigger screen will have to spend a lot more for a phone like the $200 Boost Max by ZTE, which is still a great value for entry-level phablets.

Dell Venue 8 (2014)


Design and Features

At 8.50 by 5.11 by 0.35 inches (HWD) and 11.9 ounces, the Venue 8 is larger, thicker, and heavier than the Samsung Galaxy Tab 4 8.0, which is one of the smallest 8-inch tablets we've reviewed. Available in black or red, the Venue 8's plastic body feels solid, and the narrow circular grooves adorning the back add grip and styling to an otherwise generic tablet design.

On the top right edge of the Venue 8 you'll find a micro USB port for charging and connecting to your computer. Further down is the volume rocker, and on the bottom right edge is a microSD port, which is hidden by a cover that's tricky to remove. The Power button is found on the top edge, next to a 3.5mm audio port.



With an 8-inch, full HD (1,920 by 1,200 pixel) LCD, the Venue 8 stands apart from similarly priced 8-inch budget-minded tablets. The Galaxy Tab 4 8.0Best Price at Amazon and the Asus MeMO Pad ME181C$169.00 at Amazon both sport a more common 1,280-by-800-pixel resolution. The Venue 8 shares the same 275 pixels-per-inch as the Acer Iconia Tab 8, but offers superior color accuracy to the latter's somewhat washed-out look. Viewing the Venue 8's display from the side slightly darkened the image, but the video I was testing with was still perfectly watchable. However, tilting the tablet vertically produced considerably washed-out colors.

I noticed a slight flickering effect when navigating around the Android 4.4 OS, especially on the Home screen, but that disappeared once I opened an app. The Venue 8 supports dual-band 802.11a/b/g/n/ac Wi-Fi and Bluetooth 4.0, and you can wirelessly mirror its display onto connected monitors or HDTVs with Miracast.

Android and Performance

Thankfully, Dell stuck to a stock Android 4.4 experience for the Venue 8. Out of the 16GB of storage, 10.58 are available, 1GB of which is taken up by a significant amount of bloatware. You could add up to 64GB more storage with a microSD card, which lets you add more media, but you won't be able to easily install apps onto the card.

The Venue 8 sports a 2.1GHz, dual-core Intel Atom Z3480, which handled Asphalt 8: Airborne without a hitch, showing no signs of slowing down or loss of frame rate. You only get 1GB RAM, but that's typical for budget tablets. The Acer Iconia Tab 8 $187.05 at Amazon has a 1.33GHz processor and 2GB RAM, which performed a little faster than the Venue 8.

For our battery test, we streamed a video over Wi-Fi with Bluetooth turned off and the screen brightness set to maximum. The Venue 8's battery lasted 5 hours, 37 minutes, which is slightly below average. To compare, the Asus MeMO Pad ME181C lasted just under 7 hours, and the Galaxy Tab 4 8.0 for 5 hours, 51 minutes, but both of those tablets have lower-resolution displays.

The 5-megapixel, rear-facing camera shoots relatively unimpressive images that lack detail, but then again, the Venue 8 isn't trying to be your main camera. The front-facing 2-megapixel camera is perfectly serviceable for Skype calls or Google Video Hangouts.

Conclusion

In the 8-inch tablet realm, budget and full HD were once mutually exclusive; you'd typically expect to pay up to $400 for that privilege. Spending that much will still get you a great tablet, like the Editors' Choice Samsung Galaxy Tab S 8.4Best Priceat Amazon, but it's no longer required. The Dell Venue 8 (2014) comes in under the $200 mark and will serve up all your favorite videos in full HD. It can't match the Tab S on speed or features, but it's a solid value for on-the-go media consumption.

Comparing Intel Core i5 vs. i7

There's a wealth of difference between Intel's Core i5 and Core i7 processors. We outline each CPU and explain what it all means for your next desktop or laptop purchase.

For many consumers who are on the hunt for a new desktop or laptop PC, one of the biggest considerations is the type of processor. Two of the CPUs most often in contention are the Intel Core i5 and Intel Core i7. Discounting Core i3 (mainly found in budget systems) and AMD processors (another story entirely), the difference between Intel Core i5 and Core i7 can seem daunting, especially when the prices seem so close together once they're in completed systems. We break down the differences for you.

Price and Marketing
Simply put, Core i5-equipped systems will be less expensive than Core i7-equipped PCs. Intel has moved away from the star ratings it used with previous-generation Core processors in favor of a capability-driven marketing message. Essentially, the Core i7 processors have more capabilities than Core i5 CPUs. They will be better for multitasking, multimedia tasks, high-end gaming, and scientific work. Core i7 processors are certainly aimed at people who complain that their current system is "too slow." Spot-checking a system like the Dell XPS 13 Touch ultrabook, you'll find the Core i5 to be about $200 less expensive than a similarly equipped Core i7 system.



Core Confusion

For the most part, you'll get faster CPU performance from Core i7 than Core i5. The majority of Core i7 desktop CPUs are quad-core processors, but so are the majority of Core i5 desktop CPUs. This is not always the case, as there are dual-core mobile Core i7 processors and many dual-core mobile Core i5 CPUs. You might also see the rare six- or eight-core Core i7, but that's usually found with the desktop-only, top-of-the-line Extreme Edition models.

The Core nomenclature has been used for several generations of CPUs. Nehalem and Westmere use three-digit model names (i.e., Intel Core i7-920), while Sandy Bridge, Ivy Bridge, Haswell, and Broadwell CPUs use four-digit model names (such as the Intel Core i7-5500). Thankfully, unless you're shopping the used PC market, you'll find Ivy Bridge processors in closeout systems and budget PCs, while you'll find Haswell or Broadwell processors in most new PCs. Older-generation Nehalem, Westmere, and Sandy Bridge cores are found in older PCs and generally have lower performance. The essential takeaway is that to get better performance in each generation, buy a processor with a higher model number. For instance, an Intel Core i7-5500U generally has better performance than an Intel Core i5-5200U.

Give Me the Cache

In addition to generally faster base clock speeds, Core i7 processors have larger cache (on-board memory) to help the processor deal with repetitive tasks faster. If you're editing and calculating spreadsheets, your CPU shouldn't have to reload the framework where the numbers sit. This info will sit in the cache, so when you change a number, the calculations are almost instantaneous. Larger cache sizes help with multitasking as well, since background tasks will be ready for when you switch focus to another window. On currently available desktop processors, i5 CPUs have 3MB to 6MB of L3 cache, while i7 processors have 4MB to 8MB.

A Word on Turbo Boost

Turbo Boost is an overclocking feature that Intel built into its processors. Essentially, it allows the processor to run faster than its base clock speed when only one or two processor cores are needed (like when you're running a single-threaded task that you want done now). Both Core i5 and Core i7 processors use Turbo Boost, with Core i7 processors achieving higher clock speeds.



Hyper-Threading

Intel Hyper-Threading uses multithreading technology to make the operating system and applications think that a processor has more cores than it actually does. Hyper-Threading technology is used to increase performance on multithreaded tasks. The simplest multithreaded situation is a user running several programs simultaneously, but there are other activities that take advantage of Hyper-Threading, like multimedia operations (such as transcoding and rendering) and Web surfing (loading different elements, like Flash content and images, simultaneously).

The quick explanation is that all Core i7 CPUs use Hyper-Threading, so a six-core CPU can handle 12 streams, a four-core can handle eight streams, and a dual-core can handle four streams. Core i5 uses Hyper-Threading to make a dual-core CPU act like a four-core one, but if you have a Core i5 processor with four true cores, it won't have Hyper-Threading. For the time being, Core i5 tops out at handling four streams, using four real cores or two cores with Hyper-Threading.

Integrated Graphics

The Westmere generation of Core processors introduced Intel HD graphics, which are integrated graphics built into the CPU core itself. Previous Intel-integrated graphics were built onto the motherboard chipsets, rather than on the processor. You'll find DX10 Intel HD Graphics 2000/3000 in older Sandy Bridge processors, and new DX11-compatible Intel HD Graphics 2500/4000 in the third generation's Ivy Bridge processors. Newer Haswell fourth generation and Broadwell fifth generation processors have either updated Intel HD graphics (for example Intel HD Graphics 5000), or Intel Iris/Iris Pro options. Note that while high-end Intel processors will let you play 3D games at low quality settings, you will still need discrete GPUs from AMD or Nvidia to play 3D games at 1080p with ultra quality settings turned on.

The same numerical rules apply here, so Intel Iris Pro 5200 performs better than Intel HD Graphics 4600, which performs better than Intel HD Graphics 2500. You'll find Iris Pro and Intel HD 4600 on Core i7 CPUs, while Core i5 processors feature one of the myriad versions of Intel HD graphics, depending on the part number. Integrated graphics save power, since there's no extra graphics chip on your laptop or desktop's motherboard using power.

Long story short: Intel Core i5 is made for mainstream users who care about performance, and Intel Core i7 is made for enthusiasts and high-end users. If you follow this mantra, you're likely going to find the system you need.

The 18 best smartphones of 2015 - what's the best phone?


Discover the best smartphone for your pocket, your budget and your apps with our buying guide and in-depth reviews

If you're looking for the best smartphone on the planet then you've come to the right place. Scroll down to see our pick of the ultimate smartphones available at the moment, or read on to find out about the questions you should be asking before buying any new mobile phone.

Best phones of 2015: Android, iOS or Windows Phone

The number one question to tackle is which platform to buy into. Now that BlackBerry has all but left the phone game, you have Apple’s iOS, Android and Windows Phone from which to choose.

iOS means iPhones, and you probably already know whether or not you’d like to own an iPhone. They’re great devices, with a wealth of apps and games on offer, but they don’t come cheap. That said, for anyone looking to buy a high-end phone, the iPhone 6 and iPhone 6 Plus deserve a place on the shortlist.

If you definitely don’t want an iPhone then Windows Phone and Android handsets are available in a number of shapes, sizes and prices. The downside of Windows Phone is that its selection of apps and games isn’t anywhere near as healthy as that of Android or iOS. If you want to play a new game every week, and want the best entertainment and travel apps out there, it probably isn't for you.

However, Windows guarantees you a certain level of gloss right down to the super-budget models, and Nokia’s top-end Windows Phone handsets are pretty impressive. Performance is spritely, even on the lower-end models, thanks to the minimal demands of Microsoft's Windows Phone OS - these phones just don't need high-end processors and gigabytes of RAM to perform.

For many, though, Android is the right choice. Most phones use it, and nowadays it offers a good balance of apps, games and general performance. All the most high-profile phones aside from the iPhone use Android, including the Sony Xperia Z2, the HTC One M8 and the Samsung Galaxy S5, and with Google's Android L on its way, the Android smartphones and phablets out there are only going to become more attractive.
Best phones of 2015: what size of phone?

Once you’ve made your choice of platform, you need to pick a size. This is partly determined by how much you want to spend, but as long as you’re willing to fork out £150 or more, there's quite a choice available to you.

Most of the higher-end phones are quite large these days; if you’re not used to a bigger phone we recommend trying one out in a high-street shop before buying. Most people can generally get accustomed to phones up to 5in in screen size, but anything larger than that becomes a bit of a struggle for people with smaller hands.

Have huge hands? Want a big screen? In the past couple of years, the phone-tablet hybrid market has exploded, and there are several phones that offer 5.7-6.1in screens – truly massive displays for a phone.

For any phones of 5in or larger, we recommend a 1080p screen, which will get you sharp images. Even around the £100 mark it's possible to get hold of handsets with super-sharp screens, such as the Motorola Moto G. We recommend opting for screen quality over whether it has wireless technology extras such as NFC or an IR sensor.
Best phones of 2015: 4G or not 4G?

One wireless technology that does matter, though, is 4G. Once reserved for expensive phones, this super-fast mobile internet standard is now available in fairly low-cost models too.

Although performance can vary depending on where you live and the network you subscribe to, 4G can get you around ten times the speed of a normal 3G network. While a 3G network might provide 2Mbits/sec downloads, you’ll often get 16-20Mbits/sec from a 4G network in a big city. That may well be faster than your home broadband.

Most contracts are subject to quite limited data allowances, however, so make sure you do your research before getting too excited about 4G hardware.
Best phones of 2015: how important is a camera to you?

The one other bit of hardware that’s important to consider is the camera. If you’re looking at a phone costing £200 or more, you’re almost guaranteed a reasonably good camera, but if you’re a budget buyer then you'll find most models make compromises.

Low-end phones often leave out the front camera and the flash. Some don’t even have autofocus. If a phone leaves out any such features, it cuts hugely into the photographic flexibility of a smartphone.

At the higher end of the scale, look out for optical image stabilisation. This moves the lens and/or sensor to compensate for the effect of shaky hands. It allows the phone to use longer exposures, allowing more light onto the sensor, which leads to cleaner, less noisy photos when shooting in low light.
Best phones of 2015: how much do you want to spend?

How much do you need to spend to get a good phone? Great mobiles start at around £80, with models such as the Motorola Moto E. It’s currently about as cheap a phone as you can get without having to give up too much in the way of looks or build quality.

High-end phones start at around £270, with slightly older mobiles such as the LG G2 and Google Nexus 5 providing most of what you get from a more expensive phone at a less scary price.

If nothing but the best will do, the very latest flagship phones from companies such as Samsung, LG and Sony cost between £400-500. On a contract, that normally equates to at least £30 a month, unless you’re a better haggler than we are.

Hopefully, you now have a good idea about the kind of phone you’re after. But which model should you buy? Here are the mobile phones we recommend.

Best phones of 2015


1. Samsung Galaxy S6

Price when reviewed: 32GB, £600 inc VAT



Samsung finally kicked out plastic for its latest smartphone design and, aside from a couple of reservations, the result is a triumph. The S6 looks glorious with Gorilla Glass 4 at the front and rear and coloured metal beneath it to give it a glitzy, shimmering look. And Samsung has significantly beefed up the innards without impacting on battery life negatively.

The highlight, however, is the improved camera, which now boasts optical image stabilisation and a wide f/1.9 aperture for stunning image capture in all conditions.

The S6 edge is just as good and arguably the more attractive device, but its unusual curved screen and the fact that there's no 32GB option bumps the price of an already expensive phone up to an eye-watering £760. Buy the S6: you won't regret it.

2. Sony Xperia Z3 Compact

Price when reviewed: £348 inc VAT



Sony’s pint-sized smartphone packs in a host of premium features without the high-end price.

3. Nexus 5

Price when reviewed: £199 inc VAT


Google has finally killed off the Nexus 5, but if you can get your hands on one it remains a superb smartphone. The price is significantly lower than most flagship devices and is set to drop yet further, which is why it's still one of our favourite smartphones. The design is impressive, it's as powerful as you need and the screen is great.

4. Samsung Galaxy S5

Price on 30/03/15: £330 inc VAT


There's an awful lot to like about the Samsung Galaxy S5: it's good-looking, tough, big, feature rich and we love the user-replaceable battery and memory expansion. It's a great smartphone in every way, and now that the S6 is here, the price is more reasonable. If you're not precious about the way your phone looks, the Samsung Galaxy S5 is a great buy.

5. iPhone 6

Price when reviewed: £539 inc VAT




It's a brave new world for Apple's larger iPhone, and it's much the better for it. Super-fast, beautiful to look at and lovely to use. It's the dictionary definition of a flagship handset.

6. Motorola Moto G

Price when reviewed: £140 inc VAT


A high-quality budget Android handset with an excellent screen and decent battery life. There's now a 4G version as well, for those hankering after faster mobile data.

7. HTC One M9

Price when reviewed: £580 inc VAT



HTC took the One M8's design and refined it for 2015, creating a truly stunning smartphone. The internals have been upgraded as well: Qualcomm's octa-core Snapdragon 810 SoC; the camera goes from the M8's 4-megapixel snapper to 20 megapixels; and HTC has added a host of features to its Sense Android launcher software.

It's a beautifully crafted and highly competent smartphone, just like last year's HTC One M8. But it's only a small improvement on the M8.

8. LG G3

Price when reviewed: £459 inc VAT


LG rustles up a classy, top-rung smartphone, with a ridiculously high-resolution screen and super-fast camera; but that display takes its toll on battery life.

9. Samsung Galaxy Note 4

Price when reviewed: £599 inc VAT


Samsung has produced the finest phablet yet. In addition to a new Quad HD display and a smart new look, Samsung has bumped up the speed, battery life, camera quality and range of features – big-screened phones don't get any better.


10. Samsung Galaxy Note Edge

Price when reviewed: £609 inc VAT






With most of the same features as the Samsung Galaxy Note 4 and a funky curved-edge display, it’s hard to criticise the Edge. However, that curved display, intriguing as it is, both adds to the cost and impacts upon both battery life and build quality – and that's enough to cement the Note 4 as our large-screen smartphone of choice.

11. Nexus 6

Price when reviewed: £499 inc VAT


The Nexus 6 has taken us by surprise in the short time we’ve had it. Once you sidle past the unavoidable fact of its gargantuan size, there’s an awful lot it does right. Battery life is good, the camera is excellent, and the build and design quality are second to none. And although its rivals hold an edge over it in many areas, the differences aren’t huge.

12. iPhone 6 Plus

Price when reviewed: £619 inc VAT




Apple’s 5.5in giant isn’t for everyone, but for some it may prove the perfect mid-point between an iPad and iPhone. And contrary to initial reports, our long-term review sample hasn't suffered from any undue bending - it's remained rock-solid in the face of all the abuse we've dished out.

13. Samsung Galaxy Alpha

Price when reviewed: £550 inc VAT


The Galaxy Alpha is Samsung's best-looking smartphone to date, but it's short on features and the price is too high. Come the 10th April and the release of the Galaxy S6 and Galaxy S6 Edge, we suspect the Galaxy Alpha will be consigned to the scrapheap.


14. Motorola Moto X

Price when reviewed: £419 inc VAT


Motorola’s second-generation Moto X hits most of the right notes, coupling beautiful design with a hatful of innovative and useful features.

15. Nokia Lumia 930

Price when reviewed: £419 inc VAT


The Lumia 930 is a knock-out from the first moment you pick it up. It's a Windows Phone device, so it can't compete on apps, but the design of Nokia's flagship is sumptuous and right up there with the best around.

16. Sony Xperia Z2

Price when reviewed: £440 inc VAT


Sony proves that big really is beautiful; the Xperia Z2 provides a long-lasting alternative to the Samsung Galaxy S5 and the HTC One M8.


17. Sony Xperia Z3

Price when reviewed: £477 inc VAT



The successor to the Z3 isn't that much different. It's a touch slimmer and lighter than the Z2, the screen is brighter, and the processor is clocked a fraction higher, but almost everything else is the same. It's a very good Android device, and if you can still find a Z2 for sale it will be much cheaper and almost as good.


18. Motorola Moto E

Price when reviewed: £79 inc VAT


Makes plenty of compromises to keep costs down, but performs where it counts; the Moto E is another winner from Motorola at a highly tempting price. This is the best sub-£100 handset by a country mile.

Meet the Steam Machine that wants to replace your Xbox

Zotac produces a 7in-square computer as Valve's console-killing line-up continues to grow

Zotac today unveiled its debut Steam Machine at Germany’s CeBIT expo, and it's worthy of note for one clear reason: it's absolutely tiny while still packing in the power.

Created as small form-factor gaming PCs, Steam Machines aim to challenge consoles' dominance when it comes to gaming in the living room. Steam Machines run on SteamOS, a custom-built Linux variant designed primarily to host and support Valve’s digital-distribution service for games.



By offering a much more streamlined approach to gaming PCs, Valve hopes to turn PC gaming into a much more open, accessible hobby. The machines are purpose-built to run high-end titles, without having to worry about the labyrinthine world of component upgrades and system settings.

Much like its recently announced SteamVR platform, Valve has partnered with existing third-party manufacturers to provide the hardware. 15 companies are currently confirmed to be producing Steam Machines, but as the system’s popularity increases, that number could well grow.

Zotac's steam machine, the SN970, joins a list including luminaries such as Alienware and Gigabyte. The list caters for a range of price-points and capabilities, but Zotac's entry is aimed at the more premium end of the spectrum. And it's absolutely tiny.


Zotac SN970 - specs and hardware

The Zotac SN970 features an impressive array of hardware, all of which should make it a match for most, if not all, current-gen games. It’s powered by a sixth-generation Intel ‘Skylake’ processor – most probably a Core-i5 or i7 - and backs that up with a generous 8GB of RAM.

Nvidia's GeForce GTX 970m mobile processor provides plenty of graphical power, helped along by 3GB of onboard GDDR5 graphical memory. Storage isn’t going to be a problem either, with both a 64GB SSD and 1TB of HDD memory to store your games on.

In terms of connectivity, the SN970 sports dual Gigabit Ethernet, as well as the latest 802.11ac Wi-Fi and Bluetooth 4.0. It also comes with 4 HDMI 2.0 outputs, and the capacity to run 4K monitors with a 60Hz refresh rate.



When you look at the undeniably meaty spec shet, one of the most surprising things about Zotac's Steam Machine is the form factor. Steam Machines are, by and large, small to begin with, but the SN970 crams all that kit into a body that we’d estimate to be under 7in square, with a depth of no more than 3.5in. That’s one seriously small microPC.
Zotac SN970 - price

Slightly less micro is the price – the Zotac SN970 is currently listed with a retail price of $999, or £676. While this will is substantially more than an Xbox One or PS4, it’s not as expensive as one might expect, given the quality of the internals and the average price of high-end gaming rigs.

We’ll have to hold off on an official verdict until we can run some proper tests, but it’s safe to say that Zotac's little box has got us interested. Will this finally be the machine to take SteamOS into the mainstream? You’ll have to wait until the device’s November launch to find out.
