Battery discharge

Perhaps you can provide some additional information, such as the iPad model - and how long your iPad will operate from a full charge. Are you using any specific Apps that seem to drain your iPad battery more quickly than others?

The more information that you can provide, the more likely that contributors here will be able to provide explicit guidance.

A forced-restart may help - as this will often clear an isolated software issue, or stuck process may be causing high battery usage:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

Force restart iPad (models with the Home button)

Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.

In absence of more information, if you continue to experience difficulties, you might consider seeking assistance directly from from Apple Support. You can contact the Support Team using the Support link at top-right or bottom-left of this page. Alternatively, 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:

You might also visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to test and assess your iPad:
