Call Quality

Good ol’ phone calls made with the OnePlus X are of average quality. We’re not entirely satisfied with the earpiece, which is decent in volume, but mediocre in clarity, with crackling spoiling the conversation. This makes it tricky to hold a conversation in a noisy environment, such as at a busy street downtown. The microphone isn’t great either.

Battery Life

Be ready to charge the OnePlus X every night.

With its 2525 mAh battery, the OnePlus X lasted through 5 hours and 57 minutes of testing when subjected to our custom battery benchmark. That’s an average result, and one indicative of the phone’s real-life battery performance. Long story short, one should be ready to charge their OnePlus X every night. If it is used heavily, the phone will likely need to be connected to a charger by early evening.

In dire situations, you may take advantage of Android’s built-in battery saver mode, which limits performance and connectivity to improve the device’s battery life. This improves the phone’s stand-by time significantly. There’s no quick toggle for enabling the feature, however, so to turn it on, you have to dig into the Settings menu.

For the record, our battery life impressions are based on our OnePlus X configured to have cellular/Wi-Fi data, location services, and sync for most services always on. Our favorite social networking and IM clients were also installed. Screen brightness was set to automatic, with the brightness slider set near the lowest setting.

Battery life (hours) Higher is better
OnePlus X 5h 57 min (Poor)
Motorola Moto G (2015) 8h 3 min (Average)
Google Nexus 5X 6h 25 min (Poor)
LG G4 6h 6 min (Poor)
Charging time (minutes) Lower is better
OnePlus X 121
Motorola Moto G (2015) 251
Google Nexus 5X 100
LG G4 127


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 very well, which comes as a surprise given its hardware specs. Also, the low-light performance of its camera is quite poor, the quality of the earpiece is disappointing, and the battery life could have been better. But the last few flaws we can live with considering how much the phone costs.

At the end of the day, the OnePlus X is a good choice if your budget is limited. As of this writing, it is priced at $250 (269 euro in Europe), which is fair. Also, it seems like invitations aren’t all that difficult to obtain, as we were given one only a few days after registering. Just don’t expect a lot out of the OnePlus X as a killer mid-range phone this is not.

Software version: Android 5.1.1, OxygenOS 2.1.3, build number ONE E1003_14_151123

This review just doesn't cut it. I've owned this phone for 3 months and I can assure you it is an excellent product. The screen is sharper than the one plus one which I owned originally and as good as the Nexus 5X . phones Arena you may have reviewed a faulty device or are just being biased. The build quality of the one plus x is premium. The screen brightness is excellent. Your review has faulty logic, cos how can low brightness be excellent and high brightness be poor.? That doesn't make sense at all, logically. From my experience the maximum brightness level is extremely high and you literally have to keep the phones brightness at close to minimum most of the time. It also has a very sharp amoled screen aided by the black background which gives it a striking look. . please read other reviews for this phone as they give a more balanced coverage of this phones pros and cons. With 3gb of ram and 2.2ghz the phones performance is excellent. I would say its cons are in the lack of some features such as NFC and fingerprint scanner and the fact that you had to go through the OnePlus invite system to lay hand on this beauty. Otherwise it is an excellent phone considering the price. Discount this biased review.

You might have a defective unit. The earpiece sound is perfectly fine. For me, it's the closest phone that meets my requirements for what I want in a phone.

what ??? 7 only ?, this is a way too low score for this phone. All other reviewers, including gsmarena, androidcentral, gizmodo and lots of others, highly recommend this phone. I have tried the phone myself in london, it is amazing. design and performance, including games ( u may have a defective unit, happens all the time). only for 200 quid!! I have ordered one already and it is on its way. I hope the score is not based on the US band thingy, the world is not the US, u know. Anyway, another review that shows u can not rely on phonearena reviews for ur phone buys.
