Repeated iPhone 6 "storage full" even after full restore
64GB iPhone 6 says storage is full all of the time. 12GB pictures, 1GB messages, 4GB apps, and the rest (40+ GB) is "Documents and Data".
I had this problem two days ago and did a full backup/restore that seemed to cure it (40+ GB free), but in the subsequent two days, the "Documents and Data" has completed filled my phone again. Not great for battery life either. No new apps recently, and I don't remember when I upgraded to iOS 9.2 but didn't have problem before.
iPhone 6, iOS 9.2, Verizon. I don't use iCloud at all.
Anyone have this problem and hopefully a fix?
