    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?

    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

    And take a look at the following threads about battery and how to possibly reduce it

    What if you have two sim cards?

    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
