OnePlus 2, flagship killer or not, turned out one very interesting high-end smartphone with massive interest online. OnePlus indeed succeeded into hyping the fans and it seems the company delivered for the most part.
Whether the choice of Snapdragon 810 was the right one, or not, is a question with no simple answer. The performance is more than adequate and overheating issues are not possible, as the chip has been tweaked. But what about the battery life then? Let's find out.
The day we published our review our OnePlus 2 received an OTA update, which improved on the stability and hopefully the battery performance. We updated our unit and did the tests again. The OnePlus 2 outed similar results on the media, web and call tests, but performance a notch better when left on standby.
First things first though. The OnePlus 2 is an A student when it comes to 3G talks. The phone lasted north of 30 hours, when hooked on a 3G call, which is nothing short of impressive.

Our web browsing emulates regular browsing routine and the OnePlus 2 packed enough juice to run it for about 8 hours. This isn't bad, it's not great either for a device of such caliber.

The video playback on the 5.5" display ran for 8 and a half hours - an average score, but enough for at least 5 full-length movies.

After we did our single and dual SIM standby tests the OnePlus 2 did better this time, improving its standby endurance with about 10 hours. Those new numbers also effected its final endurance rating, which also includes a standby battery draw test that is not featured in our scorecard but is calculated in the total endurance rating.
So, the OnePlus 2 scored a respectable overall rating of 61 hours - the expected time between charges if you use the device for an hour each of calls, browsing and video playback a day. If you are using the device with two active SIM cards, you'll lose an hour or two of the final rating.
