I get battery draining once in a while (once in couple of weeks) and then just reboot. Haven't pinpointed it to anything specific either. Had been very busy with other issues during the last few weeks, so couldn't even start testing aarch64/aosp10 port properly. Let's hope that it will improve. Re TG - no, I don't have account there. IRC/Matrix SFOS channels can be used, but hard to say much regarding this issue.
