Is the Android OS battery breakdown not an exhaustive list of battery drain sources?
I find that it never adds up.
One time, after not restarting the phone for a month, the battery started to drain from 70% to 0% in 8 hours while I slept.
But the battery report did not report the app that cause this drain, everything was just 5% or less. And the total doesn't add up to even 25% of that drain.
Can the battery drain not detect certain sources like stuck background apps or something?
