OnePlus 9 Pro's Battery really s.cks

   It's definitely not a software problem.  Most, if not all, TMobile OnePlus 9 Pro owners suffer with the same battery problems.  Then there is the problem with the long long long delays on updates.  I paid a $1000 for a phone a year and a half ago that is STILL on Android 11.  Why?  Because Android 12 broke mine and thousands of others phones.  It's absolutely mind numbing how long it takes TMobile to actually release their Android Updates.  I filed a BBB Complaint and an executive from Tmobile responded back.   He didn't address any of the complaints I had with the phone. Instead, be posts my payment history and acct details and said that it's not TMobile that delays the updates, but the manufacturer is to blame. I replied that was a crock of ****! Google releases the standard Android Updates and TMobile, etc adds their bloat ware to them and any other garbage they want to add.  Google released the Android 13 update Sept of last year.  Still waiting. .. ..  and waiting.   ... ..  and waiting.
