I gave it a try with wifi and location set to off tonight, dropped from 18 to 17% in 8.5h. Satisfied.

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!?

Dear iforgot and others,

This workaround helps you get rid of the drain:

Step 1. Disable location and reboot.

Step 2. Use your phone normally: you won't have a drain.

If you want to use location again, the drain will start. Regardless of whether you turn location off. You will need to perform step 1 again in order to get rid of the drain.
