How to save battery life in android

I do the following things to optimise the battery life
on Android
I will explain you with the points

1.Large battery consumption is android screen so I
turn off the live
wallpapers and put some simple wallpaper or blank
screen

2.Is brightness when you are at home you can turn
your brightness level to
low, if you need to play games or go out you can
increase you brightness
level

3. Vibration it also consume lot of power so when
you are at home you turn
it off and when you go out you can on as this is
needed outside, to do this
simple you can use some apps

4.If you are ALONE and feel like like listing music
you can use headphones
instead of loudspeaker

5.If you have dual sim option use it when only
when needed because it also
consumer battery

6.Turn off Sync, wifi, gps, mobile data use it when
needed and off it

7.Android apps also consume battery power so
keep the app if you really
need them.

8.Continuous charging your mobile i.e (chargi
ng whole night) may decrease your battery life

9.Widgets- coustmise the widgets put that on your
screen if you use it
regularly, it also consumes battery

10.Go to settings - battery and see which is
consuming more % of charge and
take action for it.
