Haksutin , via OnePlus 9 Pro , Jan 26, 2022 : I updated my 9 Pro phone yesterday to a new operating system Oxygen 12 and now i noticed that the 5G is not working and the battery is running much faster than before. Is there any new patch coming soon for this?
Father Flatulence , Jan 26, 2022 : Same thing, 5G is not showing anymore after update, only says 4G+.
Aaron2017 , Jan 26, 2022 : Some users got 5g working by putting the sim card in to sim slot 2, maybe try that as well. For the battery, considering you only did the update yesterday allow the system some time, and some full charging cycles to get optimized. It need some time to settle in and get fully optimized. If the drain continues after that you can use the unified battery thread https://forums.oneplus.com/threads/...heating-and-charging-feedback-thread.1412143/ And take a look at the following threads about battery and how to possibly reduce it https://forums.oneplus.com/threads/battery-analysis-and-battery-drain-trouble-solving.1413430/ https://forums.oneplus.com/threads/battery-facts.995140/ https://forums.oneplus.com/threads/updated-2021-no-more-lags-freezes-battery-drain-heating.1415175/ https://forums.oneplus.com/threads/guide-lower-battery-drain.1260498/
Aaron2017 , Jan 27, 2022 : Then you'll have to make choices i guess. I know it isn't a solution and it should just work period. But unfortunately it doesn't and if the workaround works you'll at least get 5g that way
