OnePlus has made waves with each successive release of their premium, mid-range handsets. Their third smartphone, the OnePlus X, continues the trend. It comes in two versions – Onyx and Ceramic. The ceramic is the heavier of the two coming in at 160grams and is also incredibly scratch resistant with an 8.50 rating on the Mohs scale. To put that in perspective, a diamond is rated a 10. The Onyx is, as the name suggests, all black and is made out of black glass with a metal bezel. Critics praise the design of both versions describing it as "damn good-looking." With that said, they add both attract fingerprints and tend to be on the slippery side. At 5.5 x 2.7 x 0.3 inches, it is also smaller than many other smartphones on the market. Many experts appreciated its diminutive size as it made it much easier for them to use one-handed and slip into their pockets.

A 5-inch, full HD AMOLED display graces the front of the OnePlus X and provides a pixel density of 441ppi. This is the first time OnePlus has utilized AMOLED technology, mainly to keep the phone thin. Still, experts preferred the AMOLED over LCD as it provided deeper blacks, better contrast and vibrant colors without suffering from oversaturation. They also note it was bright enough to read in most lighting situations. IB Times calls it "an excellent smartphone screen."

Performance was a mixed bag for many reviewers. The 2.3GHz quad-core processor is not on the bleeding edge of technology, but it is backed up by 3GB of RAM. Experts describe its performance as reliable though not blazing fast. They were able to multi-task and switch between apps with relatively little slow down. It wasn't until they fired up high-demand applications they noticed significant slow-downs having to eventually turn down quality in order to avoid frame rate issues. Battery life was also a bit of an issue. The small 2,525mAh battery only barely got them through an entire day of moderate use. They highly suggest power users bring the charger with them whenever possible. Besides this, it also lacks several notable features to keep the price tag low such as NFC, fingerprint scanner and some LTE bands for T-Mobile and AT&T. It also only comes with 16GB of internal storage though it does offer microSD expansion slot.

The 13MP rear camera failed to impress reviewers. They found the auto focus too slow and it often had issues in low light. While they were able to take decently detailed and color accurate pictures in most lighting situations, they would not describe the results as spectacular. In low light situations it performed well below other competitors. Critics noticed significant grain and noise on top of image blur due to the lack of optical image stabilization. In general, they add that this camera takes good enough pictures to share on social media but likely will not satisfy those looking for a more accurate snapper.

While there are some issues with the OnePlus X, reviewers found it to be a very solid offering at such a low price point. Android Pit states, " …if you don't expect any untold performance depth beneath the gorgeous exterior and price tag you won't be disappointed." Pocket Now adds, "…the OnePlus X wasn't built for those who notice or care about gigahertz or milliamps…It was built for those want a beautiful accessory…For those people, the OnePlus X is an excellent option."

OnePlus almost made a perfect phone

from Talk Android
OnePlus came extremely close to creating the perfect phone with the OnePlus X, especially considering its exceptionally low price point of $249. That gets you solid performance with solid battery life, a fantastic screen, and a clean Android experience... Full review

Most stylish smartphone at this price

from The Indian Express
For those on a budget, this a good option as a phone that is more stylish and compact than its competitors and just works at the end of the day. I would still urge buyers to push their budget a bit and go for the older OnePlus for the better camera and 64GB storage. Even on the performance front, that might be a better phone if you can afford to stretch. If this is your budget, then OnePlus is not bad by any standards... Full review

Great-value, good-looking Android phone

A cute phone that cuts a few too many corners

from The Verge
The things that let the OnePlus X down are its ergonomics and camera. Neither is as refined as it should be, and stronger alternatives exist to preclude me recommending that you engage in the wild chase for an invite or an open sale event for this phone. The X is cute, of that there is no doubt, but it’s not cute enough to overcome its deficiencies... Full review

Beautiful and cheap, with a baffling lack of wide LTE support

Well-configured mid-range smartphone at a fair price

from Notebookcheck
OnePlus' X nevertheless offers a lot for its money. A good Full HD panel is still not a matter of course in this price range. The cameras are decent, the battery life is very good, and the phone's sound is also compelling. The optional storage expansion compensates for the tight flash memory. The mobile wireless connections also have wide frequency coverage, as well as the option of using a second SIM card... Full review

Cut-price smartphone that looks and feels premium

from The Guardian

The OnePlus X is very good value. It’s well built, great-feeling and looks like a premium device, not one costing £200.

It lacks NFC, which is a pain for pairing devices, there’s no fingerprint scanner, wireless charging or USB-C, and it uses an old processor, but most of those features are not available on phones costing less than £350.

The camera is good, as is the screen, it lasts a good day per charge and it has dual-sim support, which is rare in the UK.

The biggest issue is actually buying one. As illustrated with the OnePlus 2, the invit... Full review


Great design and display; but camera and battery life disappoint

from tech2
OnePlus X is an interesting experiment by OnePlus to reach out to the audience that does not want a large screen phone. In terms of design and display panel – OnePlus has really nailed it. Also features such as dual SIM support and FM Radio will be loved by many. OnePlus X does deliver the goods and is a phone worth considering only in case you want to own a OnePlus device...

Good value for money

from PhoneArena

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. Most notably, the OnePlus X does not run games ver... Full review
