I turned airplane mode on, and left location services on. Battery drain was 2.8%/hr (measured over a 5% battery drain interval) with the phone only being awake for 7min 28sec when the screen was off. There were around 5min of NLP wakelocks, and some other miscelaneous ones. I don't think that explains the battery drain fully.
Then, I turned off location services, and the battery drain has been 1.7%/hr (measured over an 8% battery drain interval) with a total awake time of 5 mins, and of that only 1 min of awake time when the screen was off. Very few to no wakelocks.
What is wrong? Why is the battery draining at ~2%/hr with airplane mode on, location services off, and the phone being in deep sleep pretty much the whole time!?
