I've been having the same problem. It has something to do with Network Location.I told ya! LOL
Btw. Is anyone experiencing high percentage of the "android os" in the battery section? Mine is up to 30% and it's draining the battery a very tiny bit faster than usual. Cleaned caches and fixed perms, but it didn't help.
I took my sim card out today (and put the phone on airplane mode), and the battery went back to normal (10% drop in about 5 hours).
I can't figure out how to fix this problem.
