iOS 8 was a massive update for Apple that saw tons of new features implemented. While this was great for keeping things fresh it did have the annoying side effect of turning the release, as well as subsequent updates, into a bug filled mess. Apple has apparently learned from this mistake and announced that iOS 9 will be more focused on optimizing and stabilizing the mobile operating system.
Following the success of OS X Snow Leopard for Macs in 2009, one of iOS 9’s standout ‘features’ will be a directed focus on stabilizing and optimizing the operating system. While stability is normally an expected component in Apple software rather than a marquee feature, the rapid pace of iOS releases and feature introductions has taken a toll on the operating system’s overall performance, recently leading to numerous complaints from long-time Apple users and regular customers alike. Apple has delivered a major new release of the iPhone, iPad, and iPod touch operating system each year since 2007, generally marketing major iOS changes as a reason to buy new devices. In 2013, Apple completely overhauled the iOS user interface at the same time as it added new features such as Touch ID and Control Center. iOS 8 in 2014 refined the UI design, added Health and Apple Pay, while laying the groundwork for the Apple Watch.
