Use Your iPhone as an eReader

Granted, your old iPhone’s display needs to be big enough for this to work properly, but you can use your older iPhone to read any book, article, or file you want.

Sure, you might be thinking that you can use your new iPhone for that, but this way, you won’t have to worry about storage on your new iPhone.

You can just save all your files and books on your older iPhone and keep the new one free of files you might just read once but forget to delete.
