How do I conserve battery life?

iPhone, iPod touch and iPad

Although the iPhone, iPod touch and iPad come with a decent battery life, it's possible to run out of power during a normal day's use, especially on the iPhone. Here are some general ways you can conserve battery power:

  1. Dim your screen: The brighter the screen, the more power you're consuming. Open Settings>Brightness to adjust it to the lowest level you are comfortable with.

  2. Turn-off Wi-Fi when you're not using it: Whenever you are not using Wi-Fi, turn it off to conserve power. Open Settings> Wi-Fi and slide the button to the right of Wi-Fi to the OFF position. When it’s on, your device will constantly look for a Wi-Fi signal, consuming power in the process.
  3. Turn-off Bluetooth: Like Wi-Fi, Bluetooth can drain battery life. You only need it if you're connecting to a Bluetooth accessory. Open Settings >General and slide the button to the right of Bluetooth to the OFF position.
  4. Disable Push notifications: When it's on, your device receives notifications and displays them as badges on app icons. You’ll sometimes hear sounds indicating an incoming notification. As with Wi-Fi and Bluetooth, this feature consumes power. Go to Settings >Notifications and slid the button to the OFF position.
  5. Put your device in sleep mode: If you're not using your device, press the Sleep/Wake button to turn off the screen and put the device in sleep mode. This will help you conserve battery power.
  6. Turn off everything: If you know you won't need Wi-Fi, Bluetooth, or cellular or data coverage for a while, you can activate Airplane mode to disable all wireless communications. Open Settings and slide the Airplane Mode button to the ON position.

Note: If, after repeated attempts to charge your battery, you find it will only hold 50 percent of its original capacity, then it is "defective" by Apple’s definition. You should have the battery replaced. (See the Troubleshooting section for more on replacing batteries.)
