I have noticed excessive battery drain on my device (currently a OP3T, but had this same behavior on previous devices as well), no wakelocks though.
shows this as "unaccounted" battery usage, which usually accounts for 50% of what's using the battery. It checks out, my phone dies after 2-2.5hours of SOT, which doubled is what is expectable from a 3T.
I've tried literally everything there is to try, nothing actually solved the issue. I made a nandroid, created a secondary/throwaway Google account, logged in, and boom, everything's working as intended.
As a sanity check, I set up an old Samsung device, first with my main Google account, then with the throwaway one, and noticed the same behavior.
Now I'm pretty sure this is like a one in a million case, but do you guys have any ideas what I should try and do with my main account that could help me solve the issue?
