Turn off Background App Refresh
Background App Refresh is a feature that causes apps to update in the background to collect new information at various time intervals.
Unless you’re using a really important app that needs to be updated all of the time, this isn’t required, and turning it off can help both improve battery life and increase iPad speed for the apps that you’re using.
- Head to Settings.
- Go to the General section.
- Select Background App Refresh to disable it completely, or only keep it enabled for the most important apps that you have.
