How do I clear 455 GB system data on iPhone 16 Pro Max?

I have started using iPhone 16promax since may25. Until now I could not able to take backup until 12sep25. The reason why I did not take backup is iPhone always says not enough storage. When I check last week I found the system data took 455gb, hence not able to take backup. I need support to clear my 455gb system files to resolve my issue. Thanks.

If you have 455 GB of System Data, you have some corrupt data as that is outrageously large and not normal. When this happens the best option is to backup your iPhone using your computer, then restoring your phone from backup.

You cannot clear the system files. But you can try to optimize the storage on your iPhone. You can do this and possibly free up space, by deleting apps, deleting old photos you no longer need, old emails & messages.
