I basically learned that the battery life is directly linked to background apps you allow to run. You can actually deactivate background tasks in the settings. What I'd like to know is what specific apps are you aware of that drain the battery quicker than normal. After I deactivated everything I could, my battery only drained 2-3% overnight!
So far I can say Facebook is definitely one of the drainers along with several games for some reason. Anyone else experience this? Its pretty much like Android and apple. Some apps just drain your phone.
