Battery usage display.

Hello Mjolnir123,

Welcome to Apple Support Communities!

If we understand your post correctly, when you go to sleep and leave the phone alone you often wake up and find that the Home and Lock Screen have been active at various times during the night. We'd like to help!

You may want to try disabling Background App Refresh temporarily, as a test, to see if that is causing your phone to be active when you're sleeping: Maximizing Battery Life and Lifespan

"Background Activity. This indicates that the battery was used by the app while it was in the background — that is, while you were using another app.

• To improve battery life, you can turn off the feature that allows apps to refresh in the background. Go to Settings > General > Background App Refresh and select Wi-Fi, Wi-Fi & Cellular Data, or Off to turn off Background App Refresh entirely.
• If the Mail app lists Background Activity, you can choose to fetch data manually or increase the fetch interval. Go to Settings > Accounts & Passwords > Fetch New Data."

Let us know if you have any questions.

Thank you for using Apple Support Communities.

Take care!

Hello Mjolnir123,

Thanks for getting back to us!

Are you receiving any notifications when the Home Screen and Lock Screen activates?

Thanks!

Hello Mjolnir123,

When you see that the Home and Lock Screen have been activated, what do you see that you determined that these screens were activated.

Thanks!
