Unfortunately the update seems to have brought multiple issues.Īccording to reports, OnePlus 9 series users are experiencing battery drain, low performance and overheating issues ( 1, 2, 3, 4, 5, 6). 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.Ġ6:05 pm (IST): Recently, the OnePlus 9 and 9 Pro received the OxygenOS 12.1 C.62 update. 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. 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. What’s going on there? My phone is quite new and it should be doing almost nothing in this time, how can it use so much battery? As a comparison: My 4+ years old previous phone (cheaper than the Nord 2 btw) looses about 3% battery under the same conditions. As an example: Today the battery went down 7% over night with the phone in flight mode, WiFi/NFC/Bluetooth disabled, no ambient display and all apps closed. So I’ve been using my Nord 2 for a few months and I’ve noticed that standby uses an unproportionate amount of battery charge. I don’t use my phone a lot, so losing that much battery when doing nothing is really a problem for me. Besides, it says 93% health on the battery (considering accubattery only recognises 1 out of the 2 batteries this phone has).Tha main issue is that kind of drain on idle. I barely get 4,5h SOT… My OnePlus Nord 2 is brand new (bought like 1 month ago) and that’s what accubattery says. I have 2%/h battery drain on idle while my brother’s Xiaomi 10T has 0,4-0,3%/h and so does my Samsung Tab S7. 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.
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.
The battery drain seems to be affecting OnePlus 7 and 7 Pro users running OxygenOS 10 as well. OnePlus Nord users also jumped in on the bandwagon and reported similar battery drain issues on their devices. Last year, OnePlus 8 and 8 Pro users reported massive battery drain after updating to OxygenOS 11 based on Android 11. Another reason developers and users like OnePlus phones are OxygenOS.īut, like all other skins, OxygenOS has had its fair share of problems. OnePlus is one of those companies that started off by making flagship killer devices at affordable prices.
