Samsung galaxy -S2 battery drain problem.
First make sure that no stray app causes this problem. to check this
download "CPU Spy " app from App Store.
Make sure you close all the active apps, switch of WiFi/ 3G.
now launch the "CPU Spy app" and clear all the timers.
Lock your mobile and keep it aside for 30 seconds....
Unlock your phone and check the CPU Spy, the phone must be in Sleep Mode for the last seconds you locked the phone.
In case you find the 834 MHz progress is more.. then the Wake lock is not allowing the processor to go to sleep mode.
Workaround:
I read in many other places that this problem could be due to a silly thing due to the last time you unplug your charger cable with the Mobile Switched. So instead try to unlock your screen thereby waking up the mobile and then unplug the charger/USB cable. this will prevent the CPU to go into Wake lock situation.
