I am using an S10 Lite and facing terrible battery drain after One UI 2.5 and the October Security Patch hasn't solved the issue. I have hard reset the phone after the update so clearly this isn't because of any apps and have dark mode enabled with only airplane mode and wifi on.  I would like to roll back to One UI 2.1, is it possible ? Will it be possible through ODIN ? I also know tech stuff (coder) but wondering Samsung has disabled it in the recent years.
