My verizon samsung galaxy 3 just updated to JB from ICS 3 days ago. My battery drain is horrible now! I charge it overnight and then in morning when not in use, mobile data off, sitting idle, it is down to 42% after 5 hours After some searching it appears that removing media storage and downloads 4.1.1 is the fix:
1.I used TitaniumBackup and removed “Media Storage” and I also removed “Downloads 4.1.1″
2.ReBoot into Recovery & wipe cache and dalvik cache
3.Dirty-Flash your ROM of choice which you chose @ Step.5 and chose the same features if possible.
4.Install your prefered Kernel optional (I personally chose Ktoosez 3.0.49 just because it gave me good battery life)
5.Wipe cache and dalvik the last time and also fix permissions.
Unfortunately- that is WAY over my head. My phone is not rooted (I don't even really know what that means).
In my searching it looked like a factory reset might also fix the issue. So my questions are (finally):
What do I lose in a factory reset?
How do I save what will potentially be lost?
Will a factory reset actually fix this problem?
How does one perform a factory reset?
Thanks in advance for helping this newbie that loves her galaxy 3 [at least I did until the update ]
