Hi Kostya,
Since upgrading my One Plus 1 to Cyanogen 12.0 my battery life has absolutely crashed. Previously used to expect it to sit at 70% at the end of a busy day, now 30% on a quiet day. Used to run push mail, now turned off and doing 15 min checks. Aquamail shows as taking 35% of the battery usage. Mobile Radio Active seems to be big user at 6hr 43sec in just on 12 hours off charge.
Hope you can shed some light.
Kind regards
Dennis
