iPhone System Data too large
My 64GB iPhone XS is full. I've offloaded all the unnecessary apps. I realized 35GB of storage is System Data!
I have cleared the browser's cache. After offloading apps and clearing cache, it freed about 5GB. I left my phone alone and within 30 mins, it said it was full again, even though I didn't do anything.
I stream a bit on Netflix, Disney+ and YouTube. Some sites said those can take up cache, but I can't see how to delete it.
Any suggestions on how to clear up some system data or what would cause it to fill up when it isn't being used?
iPhone XS, iOS 16
