my ipad 4 will say 40% one second then suddenly...

It is extremely frustrating. Everyone wants to blame battery drain but my ipad 4 will say 40% one second then suddenly 10% the next second. This is not battery drain. Why is no one listening to the actual issue.

Hello Cromier,

Thanks for reaching out to the Apple Support Community. I understand you’re having some trouble with your battery percentage changing abruptly, and I have some information that may help.

Have a look at the article below for some helpful troubleshooting steps. It focuses primarily on battery performance, but it's a good place to start to eliminate some issues.

If the trouble persists, or if you have already gone through that process, it may help to backup and reinstall the latest version of iOS using the steps below.

How to back up your iPhone, iPad, and iPod touch - Apple Support

If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support

Put your device in recovery mode and set it up again

  1. Make sure that you're using the latest version of iTunes. 
  2. If iTunes is already open, close it. Connect your device to your computer and open iTunes. If you don't have a computer, borrow one from a friend or go to an Apple Retail Store or Apple Authorized Service Provider for help.
  3. While your device is connected, force restart it with these steps:  
       
    • On an iPhone 8 or iPhone 8 Plus: Press and quickly release the Volume Up button. Then press and quickly release the Volume Down button. Finally, press and hold the Side button until you see the recovery-mode screen.
      •  
    • On an iPhone 7 or iPhone 7 Plus: Press and hold the Side and Volume Down buttons at the same time. Keep holding them until you see the recovery-mode screen.
      •  
    • On an iPhone 6s and earlier, iPad, or iPod touch: Press and hold both the Home and the Top (or Side) buttons at the same time. Keep holding them until you see the recovery-mode screen.
       
  4. When you see the option to Restore or Update, choose Update. iTunes will try to reinstall iOS without erasing your data. Wait while iTunes downloads the software for your device. If the download takes more than 15 minutes and your device exits recovery mode, let the download finish, then repeat these steps.
  5. After the Update or Restore completes, set up your device.

If you can’t update or restore your device with recovery mode, or you can't use recovery mode because of broken buttons, contact Apple Support.

 

 


If the behavior persists or you run into any trouble, please reach out again.
​Best Regards.
