5 Exciting iPhone 4s iOS 9 Features

iPhone 4s Battery Life Enhancements

iPhone 4s users have also been complaining about abnormal battery drain. This is a common problem on the iPhone, particularly after major updates like iOS 8.4. Incremental updates like iOS 8.4.1 won't bring battery life improvements but iOS 9 will. 

One of the most exciting iOS 9 features for iPhone is a tangible one hour boost to iPhone battery life. The company says that "apps and key technologies have been made more efficient to trim battery usage wherever possible" which means that devices new and old should see some improvements.

iOS 9 will also bring some useful battery saving features to the iPhone 4s. A new low energy mode allows you to flip on a new mode that limits network connectivity. And by limiting network connectivity, it can save you an additional three hours of battery life. Samsung's phones come with something similar and we use the features all the time. 

What's most exciting is that iOS 9 beta testers say that these features really do save battery life on the iPhone. Just another reason why you should be excited about the iPhone 4s iOS 9 update.
