The latest Oxygen OS update for the OnePlus 6 and OnePlus 3/3T It seems all is not well for users. Oxygen OS Update For The Oneplus is giving battery drains issues. Oxygen OS 5.1.8 for the OnePlus 6 was supposed to fix some issues for Indian users reported in the Oxygen OS 5.1.6 update. Looks like that has not happened.
Users have complained about the OnePlus forums that their OnePlus 6 started to lose battery at a very high rate after the phone was updated to Oxygen OS 5.1.8. and same problem face by Oneplus 3 and 3t user.
A user has even complained that his phone had shut down at 50 percent following the update. It would seem that the screen of the device is consuming more battery than usual and it has reduced the battery life of the device to nearly half for some users. Some user also has also received the Oxygen OS 5.1.8 update, and we are not experiencing any issues with battery drain. It would seem that not all of the users are affected by this problem.
OnePlus 5 and 5T users have not reported any strange battery drain issues with their devices on the OnePlus forums. At least not yet. So there no any kind of problem with these smartphones.
Oneplus team is also starting working to solve these issue and check it what the problem in the latest update. and this problem will solve in a week.
