Just as it unveils new devices each year, Apple also annually releases a new, free operating system update. The latest, called iOS 12, drops on September 17. Apple is touting this version of the operating system as "faster" and "more responsive," meaning that the focus this year is not on adding a slew of bells and whistles, but instead, making it perform better. For more information on what's coming, visit this page, but the good news is that it will work on devices as old as the iPhone 5s and SE, which go all the way back to 2013. If you're on the fence about upgrading, just wait four days, install the newest OS, and see how you feel.
