Unable to optimize iCloud storage or update iPhone due to low storage

I am having trouble getting access to storage optimization with my new iCloud subscription. I worry that I'm stuck in a catch-22 between not having the update necessary to clear up storage, and not having enough storage for an update.


I had a baby recently and the explosion of photos has taken a lot of storage. I got an iCloud subscription so I could optimize storage and get some relief on the tight storage. But whenever I try to back up my iPhone (which I understand is a necessary preliminary step to the storage optimization) the back up goes on indefinitely and the estimated time only gets longer.


I've read online that it could be because I need to update my phone. And my phone is due for an update. But I don't have enough storage for the update. It feels like a catch-22. Wondering what solutions might be available?


Thanks!

Hi there


Please try this


Turn on iCloud Photos directly: You do not need to complete a full iCloud device backup to use photo optimization. Go to Settings > [Your Name] > iCloud > Photos and turn on Sync this iPhone (or iCloud Photos), then select Optimize iPhone Storage. 

Stop the hanging backup: Cancel the current iCloud backup attempt under Settings > [Your Name] > iCloud > iCloud Backup, as it is likely choking on your local device storage limit and isn't required just to sync and optimize your photo library.

Force an immediate manual sync: Open the Photos app, tap your profile icon in the top right corner, and select Sync Now while connected to a strong Wi-Fi network and a charger.

Thanks. I tried this. It synced for about an hour before pausing because there is not enough storage on the iPhone. Any other suggestions?
