Phone Model: iPhone 5S
Go into settings; general; storage and iCloud usage.
Out there it would show you how much is used and available. You will also get a button that says manage storage. If you select that button, on the next screen you will get a list of apps. and the amount of storage memory they have used. You can further select the app. e.g. Youtube and it will show you the app. sise and the data and document storage sise.
I would like to know if there is any way if we could remove/ delete the data and document storage. The only option I have on that screen is to remove the app. I don't want to lose the app. and I want to understand what data and documents are actually being stored on memory. Apparently I heard from another fellow iPhone user that the more storage the slower your phone gets. Appreciate any suggestions/ responses to my post.
