After iOS 1.16 iCloud auto backup not working

It seems like you're experiencing an issue with the automatic iCloud backup feature on your iPhone. Here are some steps you can take to troubleshoot and potentially resolve the problem:

1. Ensure that your iCloud storage is not full. If your iCloud storage is at its limit, the automatic backup won't be able to complete. You might need to manage your storage by deleting unnecessary backups or purchasing additional iCloud storage.
2. Automatic iCloud backups require a Wi-Fi connection. Make sure your iPhone is connected to a stable Wi-Fi network, as backups won't work over cellular data.
3. Confirm that the iCloud backup feature is enabled on your iPhone.
4. For automatic backups to occur, your iPhone needs to be connected to a power source. Make sure your device is plugged in or has sufficient battery life.
5. Try initiating a manual iCloud backup to see if it works.
   1. Go to Settings > [your name] > iCloud > iCloud Backup.
   2. Tap Back Up Now.
6. Make sure your iPhone is running the latest version of iOS. Software updates often include bug fixes and improvements that can address issues with iCloud backup.
7. Sometimes, iCloud services can experience temporary outages. Check Apple's System Status page (Apple - Support - System Status) to see if iCloud Backup is listed as having any ongoing issues.
8. If none of the above steps work, you can try signing out of your iCloud account and then signing back in. This can sometimes refresh the connection to iCloud services.
9. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it.
   2. Still not solved --> Force restart iPhone - Apple Support
10. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
    1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
    2. You can return settings to their defaults without erasing your content.
    3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.
