  • - With real world use, the Nexus 5X’s performance is pretty good.
    - Android Marshmallow is one of the best mobile operating systems around and is a massive improvement on Google’s 2015 Lollipop version.
    - Benchmarking the Nexus 5X’s scores are reasonably impressive, though.
    - Shots taken in regular light are far more impressive.


  • There’s a lot to love about the Nexus 5X, but poor battery life bars the affordable phone from our recommended list.


  • - The phone is exceedingly light.
    - Fingerprint sensor on the back is accurate and fast.


  • 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. 


  • - It comes down to this: The Note 5 and Edge+ are great phones.
    - With about 10 minutes of customization—downloading the right theme and hiding the right apps—they’re exceptional phones.
    - The camera bumps out of the back in such a way that the phone wobbles every time I touch it while it’s resting on a flat surface, and the glassy back feels pretty slippery.


  • A year ago, the conversation about Samsung revolved around design. Or more specifically, the lack of it. Devices such as the Galaxy S5 were technically solid and performed well, but were just plain ugly. Samsung’s insistence on sticking with plastic materials didn’t help either — nothing makes an ugly phone worse than when it feels as cheap as it looks. A year later, the conversation is completely different.


  • 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.


  • 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 is the package as a whole that is remarkable.
    - Just like the OnePlus One of last year, the OnePlus 2 is quite a remarkable phone.
    - The AF is a little sloppy.
    - Still, while the Snapdragon 810 is not Qualcomm’s finest hour, it remains a good processor when sufficiently tamed and its inclusion in a £240 phone it’s amazing.
    - Display quality is good too.
    - The OnePlus 2 has an LCD, IPS, LTPS screen, a great trio for any phone.


  • The lack of NFC, a microSD card slot, a removable battery, and quick- and wireless charging means the OnePlus 2 is not a flagship killer. It does have some killer new features though, including USB Type-C, 4G dual-SIM support and some powerful hardware. At £289 (we don't recommend the 16GB OP2), it's an unrivalled deal if you can get hold of one.


  • 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.

  • Rating Unavailable

    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.
