iOS 9 Storage Issue – "Other" uses 15GB

- Backup your iPhone through iTunes (choose "to this computer" option. you may want to select encrypt backup if you have an Apple watch to preserve the health data)
- Restore your iPhone and use the backup you selected in step above.

this process should free up the 15GB of garbage.

 

For iOS 9?
you need to download the ipsw from Apple.

 

use one of the many free iphone cleaner programs available

 

On your phone, go to Settings - General - Storage & iCloud Usage - Manage Storage and see if the values are adding up to your total usage. Something's either mislabeled, or you have a lot of media (or something, but 15 GB sounds like video) in a 3rd party app.

 

Do you use iCloud Music Library? I've run into an issue on DP5 (and possibly earlier) where the Music app will crash, and upon relaunching it, it will go through the "Loading Library..." step again. After that, all the songs which were previously made available offline are no longer available offline, and the storage space for them becomes "Other" in iTunes and no longer shows up in Manage Storage in Settings.

 

I've run into this exact issue. Any recommendation for cleaning up the "Other" storage?

 

My solution was to just back up my iPhone in iTunes, restore to DP5, and then restore that backup.

I had problems back in DP2 with backups not restoring properly (apparently related to iCloud Photo Library), so I turned both iCloud Photo Library and iCloud Music Library off before backing up and restoring. This was probably a little too cautious, but after losing my DP2 backup, I didn't want to take any chances.

 

Cool. iTunes gives me an error and says it's unable to complete the backup. GM should be out next week; I might just suffer through.

 

Yes. Either do the public beta now, or wait a few weeks and the final version will be available.

 

Is there a way to restore to the public beta? Since we don't have a downloaded file I'm not sure how we would go about this.
