Question

How long does the battery life stays when in use?

Answer 1

 Battery life varies a lot depending on use and background activity. My battery usually lasts a day, unless I make heavy use of it. I charge it overnight, every night, so I know I will get through the next day. Just enjoy the phone and don't obsess about the battery life 

Answer 2

Your devices' battery drain speed depends on how you use it and how long your device is supposed to last. For example if you use mobile date with your device then the devices' battery life will lose a quarter of its rightful battery life.

Answer 3

Battery life depends on what type of battery your smartphone is using and also what and how many background apps are working, phone brightness, bluetooth and wifi is on or off.
