Help me explain my battery drain

[acles003]

The thing that sticks out to me is 13% drain with the screen off.

I just did a factory reset last week. Feels like my battery life has gotten worse. Don't know if its because of 5.1.1 or after factory reset.

Your signal doesn't look to be the greatest. That might be the bigger source for your drain than GSAM thinks it is.
