Basics 

The battery icon in the upper-right corner of the status bar shows the battery level or 
charging status.

Display the percentage of battery charge. Go to Settings > General > Usage and turn on 
Battery Percentage.

If iPad is very low on power, it may display an image of a nearly depleted battery, 

indicating that iPad needs to charge for up to twenty minutes before you can use it. If iPad is 
extremely low on power, the display may be blank for up to two minutes before the low-battery 
image appears.

Rechargeable batteries have a limited number of charge cycles and may eventually need to be 
replaced. The iPad battery isn’t user replaceable; it can be replaced only by an authorized service 
provider. See 

Travel with iPad

Your airline carrier may let you keep your iPad turned on if you switch to Airplane Mode—listen 
for an announcement after boarding, or ask a member of the crew. Wi-Fi and Bluetooth are 
turned off in Airplane Mode, so you can’t make or receive FaceTime calls or use features that 
require wireless communication. You can listen to music, play games, watch videos, or use other 
apps that don’t require Internet access. If your airline allows it, you can turn Wi-Fi or Bluetooth 
back on, even while in Airplane Mode. 
Turn on Airplane Mode. Swipe up from the bottom edge of the screen to open Control Center, 
then tap  . You can also turn Airplane Mode on or off in Settings. When airplane mode is on, 

 appears in the status bar at the top of the screen. 

You can also turn Wi-Fi and Bluetooth on or off in Control Center. See 

 on page 28.
