With a lot of frustration, I have been experiencing high battery drain also, with the phone staying warm even while idle.
Following various comments, fixes, could be' on various forums, I hard reset my new, less than one week old, phone.
I was kind of annoyed, surprised it took a very long time to recover, with a picture of gears churning on the screen.
Finally it booted up with a message, reset or restore. Wasn't expecting the choice. I chose restore to see what's up.
There was an amazing amount of stuff to restore.
After restore completed, my phone was still having battery drain issues. I decided to check out what this back up and restore thing was.
Pardon me I never read the manual. No need to go into discussion of the process.
I then chose to disable back up and restore, soft reset, and boom. Battery usage is now at -2%/hr. instead of -12-20% idle.
Have any of you tried this?
Have any of you made any progress with this?
After the Hard Reset, disable back up, restore, my battery life seems to b stabilized. Most importantly, the constantly device warm issue is gone. Touching the back of the phone and feeling cool gives me assurance the device is not running amok..
I tried posting earlier, was distracted by work.
Previously, my phone, according to Battery Sense, was consuming between -22% to -11% per hour idle. After the applied procedure, power consumption has been at a high of -11% per hour to as low as -1.1% per hour, with the average being around -2% per hour with use.
I am thinking Back up, Restore is the culprit. I does not show up in your idle process and is configured on by default.
