Check battery health on iPad like on iPhone

Battery Health is currently not available for the iPad.

According to Apple Support,

For iPhone 6 and later, iOS 11.3 and later add new features to show battery health and recommend if a battery needs to be replaced.

Nowhere on the page does it mention iPad or iPadOS, so unfortunately, at this time, it's limited to iPhones running iOS 11.3 and later.

If you have a Mac computer you can download and install Coconut Battery on your Mac. Then connect your iPad to your Mac with a USB-lightning cable and run Coconut Battery. Click on "ios device" on the top of the Coconut battery display on your mac and this will tell you much about the battery in your ios device.

If you don't have a Mac go to the App Store and search on battery. There are many apps that claim to give you info about your battery. These provide different levels of information so you'll have to search for one that provides you with what you want. Many are free so there is plenty to try. I can't really recommend one since I use Coconut.

I have found a program where I can see the battery health from my iPad and also from all others Apple Devices. It names "iMazing" and I think very similar to the Coconut Battery which is mentioned in another answer.

After downloading and installing, I must connect my iPad with a USB-lightning cable to my MacBook Pro where I have downloaded iMazing.

Then open iMazing, and the program will detect your connected iPad, and you must press trust on your iPad, that iMazing can access to the iPad's information. Then you will see a screen like below:

On the bottom right (red arrow), click to the battery-logo, and you will become all relevant information to your connected device (in my example from my iPad Pro). But as you can see, you can do a lot other things with this program:

Another way, on the iPad itself, is posted at: https://www.zdnet.com/article/ios-tip-find-out-how-many-times-has-your-iphone-battery-been-recharged/#ftag=CAD-03-10abf5f Basically, you find "BatteryCycleCount" in log-aggregated-2021-01-16-xxxxxx.ips You have to choose the latest dated file.
