  • This year alone, we’ve seen several smartphones that redefined the value of what a smartphone should offer. From the super affordable ones priced below the $200 mark, such as the Moto G (2015) and Alcatel Onetouch Idol 3 4.7-inch, to the ‘low-cost premium’ phones in the $350 to $450 range, we really have to think about what the $379-priced Google Nexus 5X has to offer over the competition.Firstly, it’s a Nexus device, which means that it offers the purest interpretation of what an Android phone should be.


  • The unlocked Google Nexus 5X is an affordable plastic alternative to the larger Nexus 6P that trades its premium for better one-handed use.


  • You can operate Google's compact Nexus 5X with one hand – and it has a smaller price, too, compared with the metal Nexus 6P. Its fingerprint sensor and USB-C port take some getting used to, but it's ultimately a future-proofed phone everywhere but its memory.


  • A superb phone for those in love with phablets - this is aesethetics combined with stellar performance at a decent price... just a shame the battery still suffers.


  • The Galaxy S6 Edge+ shows some of Samsung's best, and worst, tendencies. It's a gorgeous phone with some of the finest hardware available right now, but its key feature is relatively useless, and still somewhat experimental. 


  • Buy the Samsung Galaxy S6 Edge+ if you love the idea of a wraparound screen; otherwise, you'll be able to find less expensive phones that do nearly as much.


  • The Moto X Play does a lot right with an impressive camera, superb battery life and attractive price, but there's a frustrating number of missing features and options.


  • Overall, the Moto X Play is a decent mid-range phone. But, it's not the great upgrade which Moto X owners were looking for. The camera is good, as is the screen, but performance could be better - as could battery life. Had Motorola offered the dual-SIM version in the UK and made the phone waterproof, it would have had enough to be a decent alternative to the OnePlus 2. For many, this more powerful rival will be more appealing. It's also cheaper and has optical stabilisation and the option to shoot 4K video.


  • The Moto X Play is a headset that appears to have one primary focus: long-lasting battery life. If you want an endurance champion, then the Moto X Play could well be the handset for you. There are other positives too. The design can be personalised, the camera experience is improved over the last generation, and the minimal bloatware on board makes for a solid handset with slick performance as mid-range handsets go.


  • We can't help but feel disappointed with OnePlus over their new flagship, which honestly feels like an inferior product when compared with its predecessor. Sure, the OnePlus One also had its problems, but at the time of its release it proved a respectable choice, if only because of its dirt cheap asking price.With the 2, however, OnePlus raised the price, and though we're treated to supposedly better specs, the user experience overall is just not up to snuff.


  • The OnePlus 2 offers unbeatable unlocked smartphone value, delivering top-end performance and features at a fraction of the cost of competitors—as long as you can get an invite to buy one.


  • . It's managed to conquer the tricky second album with a smartphone which builds on its predecessor in a number of ways without losing its core appeal.


  • Prior to having the chance to use the OnePlus X as a daily driver, we were genuinely excited about this phone. It seemed like a killer mid-range offering – one with great design, decent specs, no-nonsense UI, and, above all, a very tempting price tag. Perhaps we had our expectations set too high as we're now convinced that the OnePlus X is not the ultimate mid-ranger. But it is not a bad phone either. It is a good-looking handset with very responsive software and a fitting price.We did run into a number of issues, however.


  • OnePlus have just done it for a third time and created a good phone for those on a budget. It doesn't have as many fancy features as the OnePlus 2, but for the price it's an impressive set up.

    Build quality is top-notch, the metal frame looks good and provides great grip, while the onyx glass/ceramic rear are what makes the OnePlus X look stunning, we do wish the navigation keys were backlit;
    The display is excellent: it isn't among the brightest AMOLED displays we've seen, but offers very deep blacks, excellent viewing angles and chart-topping sunlight legibility.
