Can I use my phone while backing up to iCloud

Good afternoon Bejpcs,

Welcome to the Apple Support Communities!

It sounds like you'd like to know if you can use your iPhone while it is backing up, and we'd like to help.

It appears you have reviewed the What does iCloud back up? article before coming here.

Yes, you can use your iPhone while manually backing up to iCloud. However, the best practice is to let the iPhone back up overnight, which it will do automatically if plugged in to power and connected to Wi-Fi.

The resource below will provide some guidance:

How to back up your iPhone, iPad, and iPod touch with iCloud

"Follow these steps to set up iCloud Backup to automatically back up your device each day:

1. Make sure that iCloud Backup is turned on in Settings > [your name] > iCloud > iCloud Backup.
2. Connect your device to a power source.
3. Connect your device to a Wi-Fi network.
4. Make sure that your device's screen is locked.
5. If you get an alert says that you don't have enough iCloud storage space to complete the backup, follow the onscreen steps to buy more storage."

Enjoy your day!
