If you find your iPad or other iOS device won’t charge or hold a charge, here are some tips from Apple.
Will Not Charge – Change Power Sources, Adapters or Cables
Plug into the USB power adapter that came with your device. A third party adapter may not work properly. If that still does not work, try plugging into a different source of power: wall power outlet, computer, etc. Also, consider trying another cable in case the one you are using is bad.
As your device charges, you should see a battery icon with a little lightning bolt next to it in the status bar or a large battery icon on the lock screen.
Will Not Fully Charge – Force Restart, Try Again
Try this: force restart your device by pressing and holding the Sleep/Wake and Home buttons at the same time for at least 10 seconds, until you see the Apple logo. Then, let your device charge for another half hour or longer and see if it will fully recharge.
Maximizing Battery Life and Lifespan
Always make sure you are using the latest version of iOS. Go to Settings > General > Software Update. If one is available, you can plug in your device to a power source and wirelessly download and install the latest version.
Optimize your screen brightness settings to help preserve battery life. You can dim the screen or turn on Auto-Brightness. To adjust your brightness, while your device is on, swipe up from the bottom of any screen to open the Control Center and drag the Brightness slider to the left. You will see your screen get dimmer. You can drag the slider to the right to make the screen brighter.
To turn on Auto-Brightness which will adjust your screen to lighting conditions automatically, go to Settings > Display & Brightness and set Auto-Brightness to on.
Using Wi-Fi to access data uses less power than a cellular network connection. So, turn on and use a Wi-Fi network. You can turn on your Wi-Fi by swiping up to open the Control Center and tap on the Wi-Fi icon and log into a Wi-Fi network.
Low Power Mode
When your battery power starts to get low, you can turn on Low Power Mode. You may receive an alert when your battery is low and turn it on then or in Settings > Battery. Apps may then begin to perform less background tasks to save power.
The chart below shows many of the battery functions discussed in this article.
