Well, I disabled GPS for a while and left my phone with 80 percent charge. After 3.5 hrs I checked the phone because i wanted to call my friend. Battery was drained to 35%. I was wondering what could have happened. My battery is brand new and original. Then i checked battery usage. I noticed that the process "Google Play Services" drained the battery. I think disabling GPS does something funny to the wakelock of the process and keeps using the CPU all the time.
