battery drain
My iPhone 11 went from 80% to 35% in less than two hours while I wasn’t using it and had no apps running. Any idea why and how to fix it?
Question marked as
I would advise you to check battery usage, go to settings>battery you'll see a summary of which apps are consuming battery for the last 24 hours or 10 days.
Some tips to save battery is to disable background app refresh, also you can limit which apps are using location services.
To disable background app refresh, go to Settings > General > Background App Refresh
To disable location services for all apps or selected apps, go to settings > Privacy > Location Services
