How to clean up “other” storage on iPhone?

"Other" is potentially old backups of former devices you had or even current ones you have in addition to your iPhone

Check at the very bottom to see if any devices were backed up besides your own

This is what I was hoping you would get to and be able to see and where:

iPhone, iPad, and iPod touch

iOS 10.3 or later:

1. Go to Settings > [your name] > iCloud.
2. If you use iOS 11, tap Manage Storage > Backup. If you use iOS 10.3, tap iCloud Storage > Manage Storage.
3. Tap the name of any iPhone, iPad, or iPod touch that's linked to your account.
4. Tap Delete Backup > Turn Off & Delete.

**You can also look on icloud.com to find out what is in your icloud storage and delete as needed

That's the two devices you are signed into using your Apple ID.
Tap on your PC and see if it has it backed up also

Jc,

I would check on icloud.com also

You can see all of your info there and delete as necessary
