Digital Red Book: iPad Power Issues

Most iPads get between seven and eight hours of on-and-off use per complete charge. Not getting close to that? Here are a few things you can do to keep it going and going:

• Dim the Screen - Go to the Brightness & Wallpaper section of the Settings page to turn off auto-brightness and then set screen brightness to between half and three-quarters.

• Deactivate Bluetooth - If you're not  using a wireless keyboard or speakers, turn off Bluetooth by going to the General section of the Settings page. Select Bluetooth, and tap the switch to Off.

• Turn off the Modem - If you're not using the 3G/4G modem and are on WiFi, you can turn it off by tapping the Cellular option on the Settings page. Toggle the switch to Off.
