Question: "System" uses half of my storage
Apple claims that iOS 11.2 uses just under 2GB of storage. NOT 8GB! I heard that restoring your iPhone from a backup will erase unnecessary system files, e.g. previous versions of iOS, logs, etc. Is this true? And if I did, would my game levels and stuff be saved in the backup, or would I have to start fresh?
My device: iPhone 6s, 16GB.
