OnePlus 2 Review

Call quality


Seeing as our review has so far been rather negative, we were kind of hoping that the OnePlus 2 would surprise us with its call quality. Alas, that's depressingly far from the truth.

The earpiece on the OnePlus 2 is seriously problematic, with sufficient volume but abhorrent quality. Voices come in as if the other side talks through a thick towel and has a worrying cold, with overly nasal sounds being the norm. Things are slightly better on the other end, with the microphone having a better showing, though quality is still under the average for the industry, and definitely disappointing when compared to the best in the business.

Battery life


All things considered, battery life on the OnePlus 2 leaves quite a bit to be desired.

Packing a non-removable (even if you can lift the cover) battery with a capacitiy of 3,300 mAh, you'd think that the OnePlus 2 would do real well in terms of battery life, specifically as it only has to drive a 1080p screen. Unfortunately, that's just not the case, and we logged just 6 hours and 38 minutes on our custom endurance test, which is, frankly, disappointing. Even more so if you consider the OnePlus One's excellent 8 hours and 5 minutes on that same test.

It doesn't get better, either, for charging times aren't great: 150 minutes to get from 0% to 100%. Competing models from Samsung — like the Galaxy Note5 — are ready for action in almost half that time.

Battery life (hours) Higher is better
OnePlus 2 6h 38 min (Average)
Xiaomi Mi Note Pro 5h 22 min (Poor)
Samsung Galaxy Note5 9h 11 min (Good)
Charging time (minutes) Lower is better
OnePlus 2 150
Xiaomi Mi Note Pro 93
Samsung Galaxy Note5 81


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 software is filled with tiny bugs and is just slow, and we're not big fans of the new design of the phone, with its cheapo Sandstone cover. Thankfully, you can exchange it, and we suspect some of you will, especially if you're used to the OnePlus One's excellent one.

If the above was the end of our troubles with the OnePlus 2, we'd call it a day and rate it better than the average. Unfortunately, we were also troubled by the camera's extreme tendencies — nice still photos, bad video quality. Mostly good camera algorithms, disappointing special shooting modes. A lot of work here. And to top it off, battery life proved just average — average relative to our entire database.

If we had to identify the single biggest reason OnePlus failed to deliver with the 2, it would probably include the now-gone CyanogenMod OS team, which had finally managed to get a stable, smooth-running software for the OnePlus One out. The new OxygenOS is seriously undercooked in comparison, and will require some hard work to match what was available to buyers of the previous model. The OnePlus 2's only saving grace is its price. But in this case, you really get what you paid for.
