I'm experimenting with bluetooth drivers, so I may be doing weird things to the battery usage; I actually started by attributing this drain to running bluetoothd continuously. But today I killed bluetoothd and went back to the old state of the program, the drain persists. in in 6 hours, the battery drained by 18% (Change rate is 2.93%) all while the device was asleep.

I'll monitor this situation and provide more of insights.
Yeah. It's bluetooth. turns out bluetoothd running is hogging the battery regardless of whether the device is on or off. With all services killed, I can confirm overnight I've seen 0% power drain.
