Hi, first all thanks for all your work.

I have problems with my phone. When it is full charged, the battery drain too fast (200mA) so battery takes 8 or 9 hours to be discharged only.... Can anyone give me some clue?

thanks in advance

What are you doing on your phone?

How much on-screen time are you getting? If 4 hours or so, it's normal.

No, 2 hours more or less. The problem it is my phone dont go to "deep sleep".

I use betterBatteryStats and can see that in 1h 36m with the screen off, my phone is 1h 9m with CPU at 1,04GHz and the other time in "deep Sleep"

I have try to find witch proccess is reponsable of that, but i dont know how...

Thanks in advance for your help and sorry for my english.

Has it been like this from the beginning? Since you've had the phone?

Yes from beginnig I have had this problem. I have this phone three days ago.

See the link. It leads to apps which may help you find what is causing the wake lock. You also might want to try a factory reset of you haven't already.

I have had the screen off...

Please follow the post. That screenshot doesn't help. You need to see what's engaging kernel wake lock. Likely it's some app you've installed. If you can't figure out which one by looking at kernel wakelocks, then do a factory reset.

Try disabling your WiFi or configure it in settings so it's set to "off" when phone is not used.

Check if you have Facebook notification on. Turn it off if on and check if it goes to deep sleep. Facebook notification or any other push mail notification prevents phones from going to deep sleep.

Change the WiFi setting from Always on to only when connected.

And last but not least:

Set the phone to GSM Auto (PRL) in phone settings. Dial this code in the default phone Application:

*#*#4636#*#*

Scroll down and select GSM Auto (PRL) instead of WCDMA preferred.

Your phone is still doing H+ and everything, but it will stick to your phone contract provider (using their provided list) to connect to the network. With WCDMA preferred, the phone simply checks everything that is on the air and then decides, not that is not for me and checks for the next connection if it has a hard time finding a network.

Plus you need to perhaps do a Cache and Dalvik Cache reset. Never hurts.
