Ok, I recently had to replace my S2 via ATT's insurance carrier, because I broke my last one. I had already upgraded my original phone to ICS and had no issues.
Once I got my new phone though, I've had some serious battery problems. It drains down 50% or more in just 4 or 5 hours, and that's with the screen off and the phone asleep. When I check the Battery tab in "Settings" I suddenly have "Android OS" as my biggest power consumer. I looked this up as a possible glitch and found that other people had been having the same issue. It's some type of loop with the WiFi constantly trying to connect and draining power. The fix that was recommended was to set the WiFi to be always on (to cancel out the loop), and then to use JuiceDefender or a similar app to actually keep the WiFi off unless I turned it on. I did that, and it kinda works, but the battery from time to time will still drain like crazy.
I haven't gotten any new apps, and I've checked and don't have any "ghost" apps running.
Does anyone have any idea how to better diagnose what is draining the power and how to fix it?
Would rooting and installing a ROM possibly take care of it, if it comes to that?
Thanks in advance.
