Battery Life

The OnePlus 6 contains a 3300mAh / 12.7Wh battery. In general there’s nothing pointing out to expect bad battery life out of the OnePlus 6 as both the SoC and screen should be quite efficient. The most comparable phone would the Galaxy S9+ in the results, as both have the same SoC and both employ AMOLED screens of similar sizes, with the OP6 having a 6% smaller battery capacity.

In the web browsing test the OP6 ends up pretty much exactly where we projected it, at slightly above 10 hours of runtime the phone lands on the better side of battery life results for this generation. Only Huawei’s phones with larger batteries and phones with more efficient screens end up higher. Overall a very respectable result for the OnePlus 6.

PCMark Work 2.0 - Battery Life

In the PCMark test, the OnePlus 6 ends up below the S9+ - here the OnePlus 6 essentially achieving the highest scores of any Android device bar the MIX 2S also have to be accounted in the result. It’s interesting to see the OP6 beating the MIX 2S in the web browsing test yet losing to it in PCMark – the discrepancy could come due to different dynamic brightness behaviours between the phones and we can’t maintain a steady backlight level throughout the totality of the scenarios, something that’s of particular concern in the LG G7 which we’ll be reviewing in the very near future.

Overall battery life of the OnePlus 6 is excellent – of course there’s devices beating it, and most of the time this can be attributed to their higher battery capacities. Active heavy usage of the phone will naturally result in more battery drainage, but that’s also because the device is able to sustain also very high performance in a variety of use-cases.

    Battery is not user replaceable, needs surgery. Do flagships have user replaceable battery these days?
  • SpaceRanger - Friday, July 27, 2018 - link

    Sadly, no. :( I do not like the fact I can't easily replace the battery with these newer flagship phones.

    It's reasonable to assume that a glass back always implies a surgical procedure for battery replacement. User-removable panels tend to flex and are usually held in place with some sort of friction clips which just don't work when glass is selected as the material of choice.

    The only thing I wish for on my OP6 is the google dialer.

    Great review, Andrei! Thank you!

    Notch=useless phone, I still don't understand companies copying only the rubbish that comes from Apple, why don't they copy their performance, their screen quality... Etc. Worse for this phone I often found the S9 a far superior phone with much better screen and design (you get the fragility of glass but with the benefit of wireless charging), one of the best cameras out there... Etc for nearly the same price. They should get their act together and build a phone for more reasonable price and remove the stupid notch.

    As I've explained in the review, I've found the notch to not be detrimental and such a reaction seems pure overreaction.
  • Xex360 - Saturday, July 28, 2018 - link

    What bothers me the most isn't the notch as such (even though it's awful especially in person at least for me), removing jack port is just evilly stupid, but why lot of Android manufacturers copy it from Apple (small players excluded, I can see some benefits for looking like an iPhone, I yes I know Apple weren't the first to do it), why not instead (in this case) copy the X's excellent screen, wireless charging, faster experience I'm not talking about the SOC (even though Samsung should be able to compete) but by just rooting and removing some apps I made lots of Android phones much faster. Coming from OnePlus I was even more disappointed, I was waiting for some special not just copying the worse of others for a high price, especially that you can get the SO for just 30euros more.

    > faster experience I'm not talking about the SOC (even though Samsung should be able to compete)

    because it's Android, its just garbage by design. And the real problem is software "developers" who write apps, using shitty cross-platform toolkits to run it on both apple and Android.

    you know what cross platform actually means in reality? "Shitty on every supported platform".
  • Dazedconfused - Sunday, July 29, 2018 - link

    I don't get this comment. There are more than a few comparisons between recent Android phones and the X
    in everyday use situations that show Android being at least as fast in most tasks (even with a synthetically slower SOC)
