Once upon a time, iOS “just worked” out of the box. But over the years, Apple’s introduced all kinds of features to iOS that most of us don’t want to use. I’ve been an iOS user since the start, and for the first time recently decided to do a clean install instead of loading my settings from a backup. I forgot how many default settings I had to change just to make iOS useable
Now, what annoys me may not annoy you, so don’t think of this as the gospel truth for what you should enable or disable. Instead, think of it more as a resource for hunting down the settings in iOS that you probably want to take a look at (including ones that tend to kill your battery). Beyond that, there’s value in the clean install and as you’re prepping for iOS 9 (and a new iPhone), it’s not a bad idea to start from scratch and get rid of all the crap that’s filled up your iOS device over the years. Let’s make iOS useable again.
