Blowback over Apple's iOS 11 upgrade has been increasing, despite an update that was supposed to solve battery drainage issues and a large number of other glitches but apparently has not done so. Apple officially launched iOS 11 on September 19, but problems quickly became apparent, prompting the company to roll out iOS 11.0.1 just a week later. iOS 11 provides immersive AR functionality to iPhones and iPads, as well as a redesigned App Store, enhanced Siri, a Do Not Disturb feature for drivers, and the ability to share music playlists.
