Managing Your iPad’s Battery
Your iPad is powered by an internal battery that recharges when you connect it to the included power charger. How long the internal battery lasts before needing to be recharged depends on a lot of different factors—how you’re using the device, which apps you’re running, how bright you’ve set the screen, and so forth.
Recharge the Battery
Use the included power adapter to charge your iPad when you’re not using it—although you can continue to use the device when charging.
Connect the Lightning connector on the cable to the Lightning port on the bottom of the iPad.
Connect the USB connector on the cable to the USB port on the power adapter.
Connect the power adapter to any power outlet. Your iPad should fully charge in about 5 to 7 hours—longer if you’re using it while charging (which you can).
Monitor Battery Usage
The battery icon on the right side of the status bar indicates how much charge you have left. When the charge gets too low, the status bar displays the image of a nearly empty battery, and you’ll need to plug in and charge up your iPad before you can continue to use it.
If you want to know which apps are using the most battery power, you can do that.
From the Home screen, tap the Settings icon to open the Settings screen.
Tap Battery in the left column.
You see a list of those apps and system functions that have used the most battery power, in descending order. Tap to display usage for the last 24 hours or the last 7 days.
Tap any item to view how many minutes this and other items have been used.
