iPhone Storage
I have iPhone 6S with 16GB storage. Recently, it's been giving a msg about storage is full. I deleted most of apps ( some very important) but still not enough space. After checking iPhone Storage under General settings, I noticed that the phone's system occupies 5.39GB and "Other" uses 7.42GB. "Other" described as System Data. In essence Apple is using almost 13GB of my 16GB, leaving me with just 3+GB left. WTH???
