Hi,

Guys with good battery usage, when your battery is near 0% how much time was your display on?

My display taked around 65% of the power consumption, and usually when it is on around 2.5 hours my battery dies. So it seems that even if I optimize all other things to reduce battery consumtion, when my display will reach ~4 hours the battery will die.
(My math may be wrong, I assume that my battery can provide power of X (linear consumption), and if my display takes 65% of it for 2.5 hours, then
0.65*X=2.5 ==> if all battery power went to display it would be X=2.5/0.65=3.8 hours).

And my brightness is set alsmost all the way to 0.

Just wonder how much display time you get...

Im on chimera 1.1 and since the past few days my phone has been discharging 20% + overnight. Deep sleep works ok but wifi/ data switches on by itself and betterbatterystats shows powermanagerservice and wifi_rx wakelocks. What could be causing this?

I would check to see what app is wakelocking and transmitting data overnight breaking DS. Find that app that is polling or opening and you'll find your source. Can you post a screen shot of betterbatterystats that shows it and I'll look more into it?

Looks to me that your Facebook acct is sync-ing your contact and calendar. I would make sure you turn off your auto-sync and when you want to poll, do it yourself.

Also looks like you Android OS is taking a big chunk too. Might want to look at your media scanner and adjust the scanning frequency. I use PowerAmp as my music player and QuickPic as my gallery (I have completely uninstalled both Google Music and stock gallery) .

Are you uploading pictures through Picasa (Google+) or Facebook. Those will kill your battery bc it does it everytime you take a picture or download one and then scans your system the whole time looking for any new ones you might have.
