Manage Your iCloud Settings
If an app is using iCloud, it’ll constantly upload content from that app to the cloud so you can use it on your other devices. That can drain your battery life, so it’s better if you manage it so not every app uses it.
- Open the Settings app.
- Tap your Apple ID name at the top of settings.
- Tap on iCloud.
Tap the toggle next to any app that you don’t want using iCloud. Not every app needs to use iCloud services, especially video games. They both drain your battery and reduce your iCloud storage.
