Hi all,
I'm have recently discovered that my S3 is not going into deep sleep at all.
I have downloaded CPU spy and BBS. BBS showed that my kernel wakelocks has something called PowerManagerService which prevents my phone from going to sleep. Following the instructions i read, I went to partial wakelocks and discovered discovered that there is MANY AlarmManager running from different apps. I deduce that this may be what is preventing my phone from going into deep sleep and thus draining my battery. I seek help from you guys to see if there is any solution to solve this problem if possible, I would like to avoid the solution of factory restarting. Thank you very much!
