The battery inside your smartphone can be recharged about 1,000 times before it needs to be replaced. One way to extend the life of your battery is to do just a few things to help preserve its lifespan. One easy tip is to take your phone's ring tone off vibrate; the buzzing motion uses more power than noise, and silent mode is the most energy-efficient. Also, disable any animated screensavers on your phone. A still image uses far less energy than one that moves.
