WHAT IS IT?
iPhone comes preloaded with settings and apps that can slow things down. Step by step instructions included.
Your iPhone has many configurable settings, some of which make life easier. Others control apps or features you never use. And others still are not worth the battery drain.
Apple technically asks you to opt-in to some settings when you set up a new iPhone, but you might miss these steps in your excitement to get your phone up and running.
