OnePlus One full review

OnePlus must be the only company in history to increase the price of its year-old phone, but the OnePlus One is still a great deal: the mid-range smartphone with premium specs. Is the OnePlus One a bargain? Read our OnePlus One review to find out. Features: OnePlus One benchmarks, specs and new features.

OnePlus One review: What it is

The One from OnePlus is a high-end smartphone at a mid-range price. It's an Android smartphone running an OS based on 4.4.2 KitKat, with high-quality specifications, but in the UK it retails for just £229 - for now. As of 25 March in response to the falling value of the Euro the price will be increased to 299 Euro for the 16GB model and 349 Euro for 64GB (up from 269/299 Euro). It's still a great deal, though, around a third of the price of the most expensive smartphones with which it shares key specifications. The catch? Well there really isn't much of one.

From the beginning you've needed an invite to buy the OnePlus One and after moving to not needing one on a Tuesday, the firm has removed the system entirely and forever, not a short period of time. You can now purchase without restriction but the firm has warned that the OnePlus 2 will use an invite system when it is launched.

You have to buy it SIM free, too, but that's always the cheapest way to buy a phone anyway. So the question is: is the OnePlus a bargain? Read on to find out. (See also: Best smartphones UK.)

OnePlus One review: Build and design

Initial impressions are good. Very good. The OnePlus is well put together, and made of what feels like high-quality materials. A big, understated slab of black, look closer and you will find subtle curves. There's a chrome outer rim surrounding the large glass display, which is slightly raised beyond the rest of the handset.

The only major caveat is that the bezel at the top and bottom of the OnePlus One's display is bigger than we'd like. Put it next to the LG G3 - a phone with a similar-sized screen - and you'll see a big difference.

For the record the OnePlus One measures 153 x 76 x 8.9 mm and weighs in at 162 g. It's neither the thinnest nor the lightest big-screen smartphone on the market, but it feels good in the hand. Solid, but ergonomic.

The back of the handset is made of a material we can't place, with a finish we haven't seen before. It's rough like carpet, but soft to the touch. Like a material finish. That sounds bad, but it isn't. Everyone who picked up the OnePlus One in our office commented on and liked this.

The OnePlus One is available in black or white. We tried the black model, and we like it. It's different to other phones on the market, and in a good way.

OnePlus One review: Display

The whole phone is built around the display. It's a 5.5in IPS LCD capacitive touchscreen display boasting 16M colours. The resolution is impressive: not the best on the market, but plenty good enough at the best at this price. Spread over 5.5 inches, 1080 x 1920 pixels makes for a pixel density of 401 ppi. And how does it look? Sharp. Impressively so.

Watcing movies, viewing images, and browsing the web all look good. Colours are deep, resolution sharp. The only issue we had is that some colours look a little overblown. Whites on photos have a slightly yellowish tinge. It's good to look at, but doesn't feel particularly accurate.

Zoom in on text, however, and you will have to get very close before you are disappointed. Viewing angles are good, and the screen is lovely and bright.

The multitouch works well. It's rated for up to 10 fingers, but you'll have to take OnePlus's word for that. I'm in no way capable of using all 10 fingers at once on a laptop, let alone a phone. And we're impressed with the inclusion of Corning Gorilla Glass 3 in a 'cheap' phone. As indeed we are impressed with the display as a whole. It's a big thumbs up from me.

OnePlus One review: Specification

Here's the really good news: the spec is that of a £600 phone. You get a Qualcomm MSM8974AC Snapdragon 801, a quad-core Krait chip clocked at 2.5GHz. It's paired with 3GB RAM, and graphics are taken care of with a Adreno 330 GPU.

Connectivity specs include 4G LTE, 802.11 a/b/g/n/ac Wi-Fi, NFC and Bluetooth 4.0. But how does the One perform?

OnePlus One review: Performance and benchmarks

You might expect that a less expensive smartphone would fall down on performance. But here again we are happy to say that things are good. In use the One feels zippy. Transitions are snappy, and even running multiple processes the OnePlus One keeps things moving. Even heavy-loading games run well on the OnePlus One. It's as good a performer as we've seen in the Android space. And that's praise indeed.

Benchmark scores bear this out. As ever, take synthetic benchmarks with a pinch of salt. They offer a guide to performance and nothing more. But in Geekbench 3 the OnePlus One managed average scores of single-core: 969 / multi-core: 2570. That puts it close but not quite up with the Samsung Galaxy S5. And that's more than okay.

Similarly in the GFXBench T-Rex onscreen test, an average score of 28.5fps (1,596) is very good if not top of the shop. And we got a very good result for javascript performance in the Sunspider benchmark: 877ms is excellent in this test.

Overall then performance is good. The OnePlus has the specification and the performance of a much more expensive flagship phone. Impressive stuff. (See also: The UK's best Android smartphones.)

OnePlus One review: Storage

There are two storage options for the OnePlus One phone, and one big disappointment. The options are 16GB and 64GB - strangely no 32GB but it's becoming very rare to see 64GB on offer outside of the iPhone. And the disappointment? There is no storage expansion slot.

We tested the 64GB model, which came with 54.8GB free out of the box. And that's pretty good. But we do regret the lack of expandable storage.

OnePlus One review: Cameras

The OnePlus One has a 13 Mp Sony Exmor camera, with dual LED flash, and f/2.0 aperture. OnePlus tells us that the One camera has six physical lenses for greater detail, even at lower light conditions. It offers geo-tagging, touch focus, face detection, panorama and HDR, and captures video of up to 2160p (4K) at 30fps.

We haven't had time to test the camera as much as we'd like, but our early impressions are decent. The OnePlus can't match the superior cameras of the Galaxy S5 or the Xperia Z2, but it is perfectly adequate for a smartphone camera. You can take good photos with it.

Around the front is the 5 Mp selfie camera. This captures video at 1080p (Full HD) at 30fps for video calling. Overall the cameras are good if not top notch. Good enough, we'd say, considering the price of the phone.

OnePlus One review: Software

Here's where things get really interesting. The OnePlus One runs Android 4.4.2 KitKat, which is a sufficiently recent version to be great. But it is a customised version of Android. Indeed, it is different to Android, running an interface known as CyanogenMod. (OnePlus has now confirmed that within three months of Google releasing the final code for its forthcoming mobile OS the OnePlus One will also get Android L.)

Don't be frightened. You get access to Google Play. And when first you boot the OnePlus One you are asked if you want to run a custom OnePlus theme skin. If you opt not to go for this (we didn't) you get a very vanilla Android interface. It's all but a Nexus phone in that respect.

The interesting aspect is that you can install CyanogenMod themes that allow you to build your own skin for your smartphone. Choosing a specific theme allows you to tweak app icons and system fonts, your wallpaper, lock screen and so on. You can also specify changes to the way your smartphone works. But there is a caveat: the themes cost money, mostly. You won't break the bank buying them, but personally I'd rather live with vanilla Android.

OnePlus One review: Battery life

The OnePlus One comes with a large Li-Po 11.8Wh (3100 mAh) battery cell. And we have been impressed with battery life.

Out of the box the initial charge wasn't great, but it took a long time for the OnePlus to ship to me, so we won't hold that against the handset. Much more important is that with light use, 24 hours after charging, 67 percent of the battery life was left. That's a strong performance: we hadn't been doing much beyond email, messaging and social media, but that kills our iPhone 5 in 24 hours. Of course the battery will degrade as time goes buy.

Nonetheless, 48 hours after charging there is still 39 percent of battery life. And in the second 24 hours we made a point of streaming video clips, using Bluetooth and Wi-Fi, and running benchmarks to simulate heavier use. The OnePlus One charges quickly, too, so we'll forgive the US charger and adaptor with which it ships to the UK. It doesn't always want to charge via USB, even when we can get it to mount via the USB port and cable. Odd.

OnePlus tells us that the battery life is helped with an energy efficient display which adjusts the level of backlight and differentiates between dynamic and static content on the screen to reduce power consumption. We'll keep an eye on battery performace over time. But so far we are very impressed.
