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.

    Using the phone from just over a month - great display and battery life. Pretty impressive camera for my occasional use. The update policy changed recently if I'm not wrong, were the older phones (X, 3, 3T) supported this well with upgrades? Reply

    The last 2 security patches for the OP3/3T were released 4 and a half months apart. The release pace has been very inconsistent but there are a large number of betas for some reason.

    The X only got one major version upgrade... to a version that was already out before the phone was released. The 3T got 2 major version upgrades... and the first one was to a version that was already out before the phone released. Supposedly it's going to get 8.1 eventually. They did live up to the promise of releasing Nougat in 2016 by releasing it on December 31.

    I would like to see a review of software updates. I think One Plus started good but now it has even worst track record than Samsung. I think this part is more important for me rather than CPU performance which is something you get like basically every other company phones of that year. Reply

    They posted a Software Maintenance Schedule a few weeks ago claiming 24 months of "Regular Software Maintenance" which includes major version upgrades and bi-monthly security patches followed by another 12 months of "Software Security Maintenance" with bi-monthly security patches.

    And yet, OP3T was released November 2016 and they are not going to update it to P.

    Android P isn't out yet...and its probably going to be released around September this year so expecting the 3/T to get it is stupid. Reply

    Obviously P isn't out yet, I did not say I was expecting them to release it before Google. They have already said they are never going to release it for the 3/3T. Reply

    It is stupid to not expect these companies releasing updates for their phones and turn them into paperweights. Reply

    The 3/T has just been confirmed for P. Reply

    Yes I just saw this, very happy that they changed their minds about it (they had in fact already announced that Oreo would be the last major update). I hope this is a real turnaround for the company and they start taking updates seriously because OP's hardware is great but I have been rather disappointed with their software to date. Reply

    Is the battery replaceable or does the back cover require surgery to remove? Reply
