On September 19, 2012, iOS 6 was released to the iPhone 4S among other compatible iOS device as an over the air (OTA) upgrade package.  According to Apple the update contains 200 new features and tweaks, which includes a new maps app, dubbed Apple Maps, Facebook integration and Passbook, an application that allows users to store their coupons, boarding passes and tickets digitally.  On September 18, 2013, Apple released iOS 7 and the iPhone 4S is among other compatible iOS devices that also receive the update without any lagging issues compared to the iPhone 4. Although the device has improved performance over iOS 7, some newer features that were released to newer models such as AirDrop and CarPlay were not supported. The iPhone 4S can also run iOS 8, which was released on September 17, 2014. Given that the device was supported for more than 3 years, some newer features of the software such as Apple Pay were not supported. It is also unable to work with Apple Watch due to the relatively aged hardware. In fact, some users often reported that performance on the 4S is very slow, similar to how iOS 7 ran on the iPhone 4, and suggesting that they should not upgrade due to battery draining issues and hanging up on calls. Meanwhile, Apple released iOS 8. 1. 1, which brought slight improvements to the phone and the iPad 2, but it still did not run as fast as newer models.
