New updates are being added at the bottom of this story…….

Original story (published on January 4, 2022) follows:

OnePlus is one of those companies that started off by making flagship killer devices at affordable prices. Another reason developers and users like OnePlus phones are OxygenOS.

But, like all other skins, OxygenOS has had its fair share of problems. Last year, OnePlus 8 and 8 Pro users reported massive battery drain after updating to OxygenOS 11 based on Android 11.

OnePlus Nord users also jumped in on the bandwagon and reported similar battery drain issues on their devices. The battery drain seems to be affecting OnePlus 7 and 7 Pro users running OxygenOS 10 as well.

While it is normal for a phone to drain battery right after an Android update, many say that the issue persists months after they updated their phones.

It looks like OnePlus never bothered to fix the issue with OnePlus 9/9 Pro, OnePlus 8/8 Pro, and OnePlus Nord users now reporting that their phone barely lasts a day thanks to the constant battery drain.

Some are saying that the Reddit app is causing the battery drain, while others who don’t have Reddit installed say they are affected as well.

It looks like OxygenOS 11 has a wake lock that keeps the phone awake even when the screen is off, but we cannot say anything for certain.

Moreover, since OnePlus is yet to say anything on the matter, it still remains unknown if users are at fault or there is some issue with OxygenOS itself.

Update 1 (July 27)

06:05 pm (IST): Recently, the OnePlus 9 and 9 Pro received the OxygenOS 12.1 C.62 update. Unfortunately the update seems to have brought multiple issues.

According to reports, OnePlus 9 series users are experiencing battery drain, low performance and overheating issues (1, 2, 3, 4, 5, 6). Even the benchmark results are lower than before (1, 2).
