[Q] Cyanogenmod 10 battery life on normal usage.

view story

http://forum.xda-developers.com – Hi guys, I recently switched to CM 10 (Android 4.1.2) and the battery life is significantly lower than what I had on the stock ROM and the new Sense UI... I guess. My phone won't run longer than 10-15 hours a day with normal usage, which means Wi-fi and 3G always on, screen on automatic brightness being used for about 1 hour in total (for one charge). However Android OS, Cell Standby and Phone Idle still account for the most battery usage, which I find weird. I have no wakelocks and my device goes to deep sleep when not used. Is this normal behavior with the new Cyanogenmod and Jellybea (HowTos)
