Better Battery Life Many things influence power drain on your iPhone:
- Check for the tiny blue Play triangle at the top right of your iPhone screen, Sometimes your iPod can be running and you don't know it. Press the iPod icon and then hold the Home button for about 6 seconds to shut down the iPod.
- A reset by holding Home and the Sleep button on the top right of your iPhone for about 10 seconds will dump out of all running apps.
- Turning off WiFi can improve life when not connected to WiFi since your iPhone is searching for it continually.
- Set Mail to retrieve once an hour or manually.
- Press the Home button before sleeping your iPhone. If you have an app on screen that uses the Net, like Safari, Mail, Maps, Stock, Weather, etc, these will continually try to update and burn the battery down quickly.
