[Q] Battery drain in CM10.2 nightly
I'm using Cm10.2 nightly and my battery lasts for some 12-16 hours only. Using the same setup with CM9.1 the battery will last for some 3 days!
I checked the stats with wakelock detector and could identify what seems to be responsible for the drain.
It i caused by the Phone app. I have a VOIP account setup with following settings:
- receive incoming calls
- transporttype: UDP
- send keep-alive: always
Looking at the stats, the drain is caused by 'SipWakeLock'. I have noticed that when disabling WIFI-Optimization, the amount of SipWakeLocks was reduced a bit. SIP is running over WIFI.
Anyway, using the same configuration in ICS the amount of SipWakeLocks is much lower. Just to give you an impression of the stats:
Statistics for 4h
2h10m are used by Phone
SipWakeLock count is 1200 and 2h10m time.
Device is awake 95%
Sipwakelock count is 230!! only and 13s of time.
Device is awake 16%
So can anyone advise what can be done? I woul like to contact the devs, but don't have enough posts yet. Can/has this issue to be fixed in the code?
Thank you and best regards,
