Question marked as
Your iPad can be expected to occasionally charge to 100% even when choosing to limit charging to 80%. This strategy is deliberate, being necessary to calibrate charging and maintain battery health.
That said, if your iPad is unexpectedly always charging to 100%, it may be necessary to reset your iPad settings. While this reset will not cause any loss of data, as a precaution, it is always wise to ensure that you have a current iCloud or iTunes backup before performing the reset:

When you are happy to proceed, you can perform the reset from iPad settings:
Settings > General > Transfer or Reset iPad > Reset > Reset All Settings
If the problem still doesn’t clear, the next step is to reset the iPad to factory settings:

Alternatively and perhaps easier, you can initiate and manage your support cases using the excellent Apple Support App. If not already installed on your iPad, the App can be downloaded from the App Store:
