Just in yesterday we have covered the top features of the iOS 9 which includes the improvement of battery efficiency. It is proven that iPhone 6 with iOS 9 will provide an additional 1 hour of usage time. iOS 9 also comes with power saving mode which is a ‘not so new’ feature to crank down consumption of every single juice in your iPhone or iPad.
The Low Power mode is a new feature which is similar with the Android M Doze mode. It reduce the internet consumption and reducing hoggling app and thus makes the iPhone runs for a longer period. The Low Power Mode can be turned on in Settings under the battery category.
