Extend battery life

Below are some tips for making your battery last longer between charges, e.g. by turning off features that you don't need and by monitoring how apps and system resources consume battery.

Reduce the display brightness

  1. On a Home screen, touch the Menu key (=).
  2. Touch "System settings".

Set a shorter Sleep timeout

  1. On a Home screen, touch the Menu key (=).
  2. Touch "System settings".

  4. Touch "Sleep".
  5. Touch the desired option - the shorter the Sleep timeout, the less power will be used.
