I have an iphone 4s on ios 7.1.2 and I restore it regularly because the "other" gets too big and because the settings badge regarding the ios 8 update shows up. I want to do this: wipe the iphone data from "settings-general-reset-reset all content and settings", install all the apps with itunes, set up every app (for example sign in on twitter, facebook and other apps) change some settings in the "settings" app and than back up with itunes. After a while, when I have to restore again, I want to use the same back up I did above, is it bad? will this make my 4s slower? Because I hear all the time that using a back up can get errors.
