Uhm, Pengus... hlp.
Some pretty serious drain. Happens always just after phone is out of range of connected AP. Normal battery usage with mobile data (3G/HDSPA) is something similar to wifi usage (roughly 1-2 % per /h), but nothing like this. Workaround is to disable and enable wifi, after that battery usage normalizes to 1-2% per h. Tried with your build of CM10 w/ your kernel and everything extra installed (dhcp / wpa), and with newest PA, same thing happens.
Actually, if you have a possibility to try it for yourself, here is how:
- Connect phone to wifi AP.
- Power off AP.
-> Lots of drain.
- from phone -> wifi off & on again -> no drain
Works for me every time.
Logs attached, and some pretty pictures. Disconnected from AP at roughly 19:02.
