I can't back up my iPhone with iCloud

Hello, Ladybugkay.

Back up iPhone using iCloud

1. Go to Settings  > [your name] > iCloud > iCloud Backup.
2. Turn on iCloud Backup. iCloud automatically backs up your iPhone daily when iPhone is connected to power, locked, and on Wi-Fi.
3. To perform a manual backup, tap Back Up Now.

To view your iCloud backups, go to Settings > [your name] > iCloud > Manage Storage > Backups. To delete a backup, choose a backup from the list, then tap Delete Backup.

Hello, iCloud isn't meant for backups at all, I believe the only way to backup an iPhone is to a Computer.

Thanks for correcting me! :)

I am still but the padawan learner, oh Jedi master! 😉
