Tip - Switch off the vibrate function on your phone, and use just the ring tone instead

Switch off the vibrate function on your phone, and use just the ring tone instead. The vibrate function uses up a lot of battery power. Keep the ring tone volume as low as possible.

Turn off your phone’s back light. The back light is what makes the phone easier to read in bright light or outside. However, the light also uses battery power. If you can get by without it, your battery will last longer. If you have to use the back light, many phones will let you set the amount of time to leave the back light on. Shorten that amount of time.
