On rooted phone I started to prevent starting everything related to google and DRM, market etc. (autostarts https://market.android.com/details?i...oid.autostarts):
- Factory Test*
(i think this was all, i'll recheck if there was something else)
And guess what. The battery drain over the night is now around 2% and the phone is quite able to survive 2 days (not completely accurate as i had it connected to computer for 10 minutes in between to pump some files from it), after the second night i still had 12% of battery left.
If someone else is able to repeat that, please report the results and if someone is able to figure out which app exactly is draining the battery even batter.
One thing i dont really understand is what are those apps doing during the night, there is no reason to contact any of google services as i dont have any account entered, so wtf are they doing?!
To ROM cookers, please stop adding google apps by default, make them as package to be installed later if you wish.
I do not have any communication or at least there should be none over 3g (droidwall) and i dont want to kill aplications just to have peacefull sleep. I was searching for final solution and i have found it.
