Improve iPhone Battery Life



Optimize the iPhone settings for best battery performance

To maximize battery life, you should disable unneeded and unused features:
  • Enable Auto-Brightness adjustments – having your iPhone screens brightness jacked up will drain the battery quick, use the auto-brightness feature in Settings -> Brightness to have your iPhone automatically adjust to ambient lighting
  • Minimize or disable location services – each time a location service is used, the GPS unit in your iPhone activates and uses more battery.
  • Turn off push notifications – disabling all push notifications will help extend battery life because the iPhone is not transmitting data when an application isn’t in use. You can also selectively disable push notifications for apps that you don’t want push updates for. You can do this within Settings -> Notifications
  • Lock your iPhone – locking your iPhone when it’s not in use will prevent accidental taps and screen touching from activating the display and draining the battery
  • Reduce mail check intervals – do you really need to check email every 5 minutes? Reduce the mail checking interval to conserve battery life
  • Disable push mail – same theory as above
  • Disable Keyboard clicks – the keyboard clicking sound uses processing power to play each click
  • Limit use of vibrating apps – many games and apps use the iPhones vibration feedback feature, limit the use of this feature or disable it within the apps themselves
    • Quit apps running in the background – Since iOS 4 you’ve been able to run apps in the background with multitasking. This is a great feature but some apps will drain your battery when used in the background, like Pandora. Quit background apps when they are not in use.
  • Use Airplane mode – if you know you don’t have coverage or you don’t need cell service, enable Airplane mode to stop the iPhone from constantly searching for cell towers. This is a great tip to preserve battery life if you’re somewhere without coverage.
  • Turn off 3G – 3G is faster but also uses more power, if you have limited 3G coverage or you aren’t transmitting a lot of data, disabling 3G will improve how long your iPhone battery lasts
  • Turn off WiFi – if you’re not using WiFi, disabling it will improve your battery life since the iPhone will stop searching for WiFi networks
  • Disable Bluetooth – disabling Bluetooth can save quite a bit of battery life
  • Disable the iPhone EQ – turning off the iPhone equalizer provides a boost to battery life when listening to music
  • Turn off the iPhone – if you’re not using it for something and you don’t have cell coverage, just turn the iPhone off. Simple.
