Wonder if anyone else is having these issues. Went from T-Mobile to EU version, updated to C33 last night and I still have horrible battery life.

Phone has a massive battery drain and when I restart takes over 5 minutes to connect to cell service, sometimes even longer.

Any thoughts? Thinking of going to a custom rom

My first post on XDA forums. but just reflash using the TMO msm tool https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4180981/ choose OOS 11.0.7.9 then use the TMO to EU msm tool again, unlock the bootloader using the unlock.img you got from oneplus then run through the setup after this internal storage wont be wiped. then download the oneplus updater tool. turn on advanced mode, go for the stable full version but instead of choosing your device as the EU version, choose just oneplus 8T that way you get the international version. install full OOS update. not increments. Then just update to the latest android 12 from settings, about phone and update. if you want to stay on android 11 then make sure that you do all those steps again before using the updater app to upgrade to android 12. just install the latest OOS update from oneplus 8t repo ( https://forum.xda-developers.com/t/oneplus-8t-rom-ota-oxygen-os-repo-of-oxygen-os-builds.4193183/ ) 11.0.13.13: OnePlus8TOxygen_15.O.31_GLO_0310_2202182359 go to settings and search for update. click on the cog and choose the OOS 11 update. Sorry if I made any grammer mistakes. If you want root I'll reply with the easiest way I found to root oneplus 8T. The latest update too.

thanks for the reply, so the International version is the better build? I submitted for the bootloader unlock key. Still waiting.

thanks
 
Technically you can already flash regular kebab 2005 without unlocking the boot loader unless you want to have root. Just download the full update from oxygen updater and locally update to the INTERNATIONAL version without boot loader unlocked.
