Cyanogen OS 12 was recently announced with Android Lollipop. While it has great features, some users have reported a huge battery drain. The root cause of this drain has been found out and it is believed to be OTA update component of Google Play Services (SystemUpdateService), which was disabled in KitKat and earlier versions of Cyanogen.
