I have a 256gb iPhone 13 Pro Max and couldn't even download a new app today because I was out of storage. After offloading apps, deleting some videos/photos/etc, I was able to free up around 6gb of space. Still after all of that, plus rebooting, updating, syncing to my MacBook Pro, etc, I'm still at 89gb of "other system data." When I first got this phone and transferred everything from my previous iPhone 12 Pro Max, I was almost out of storage due to something weird happening when transferring data, but it was never this bad. What do I do? You can see that I don't have a bunch of crap taking up all my jiggabytes. I'm starting to think this is a Storagegate problem created by Apple in order to force everyone into paying for more and more iCloud storage.
