Hey guys, I just had a new battery put in my iPhone 6S so it's ready to go for another year or more. But I would like to reset the entire operating system. I have been "Restoring" the iPhone each and every time I got a new one ever since my first 3G, which I think is causing some lagginess and possibly other issues. So I would like a fresh installation of the OS. I just wanted to confirm that going to: Settings > General > Reset > Erase All Content and Settings is the proper way? Will this give me a clean installation of the iOS? Or do I have to do something different thru iTunes or something?
