Here we are going to discuss about improvement of battery performance.
1. Minimize vibrations and haptic feedback.
Do not Keep Unwanted Apps as the use battery in back ground. The rotation of this load produces vibration. Head over to Settings>>Sound.
You can disable the vibrate on touch and other options if not required.
Custom keyboard apps also provide additional settings to turn off
vibrations while typing.
2. Display optimizations trick
Apart from the processor, display consumes most of the battery power. Do
not ever set your phones battery to auto Brightness Mode as it consumes
much much battery as it always recognizes the light falls on the sensor
and the brightness level tries to set accordingly.
