1. ValueWalk wrote that Apple's new OS will provide users an improved battery life. Users are encouraged to activate the new "low power mode" if they require extra hours from a single charge.

The new mode can be set off when the battery reaches 20%, or manually at whichever time, ValueWalk noted. To make the battery last longer, functions such as push email fetching and automatic downloads are disabled. Performance of the device, however, will be affected a bit.

According to the news outlet, the power settings menu also shows "a list of which apps are using the most power, and can choose to close or remove power-hungry apps to improve battery life."

2. Proactive is a system-wide feature that allows iOS devices to provide recommendations based on the users' habits, whether it's about place, time of day, and activity, Know Your Mobile reported.

3. The iOS 9 is also equipped with multitasking features, such as the Split Screen and PIP for the iPad. Split Screen works by swiping left from the side of your screen to pull up a SlideOver window, the news outlet noted.

The PIP, meanwhile, can be utilized on the iPad by minimizing a window playing a video when you open another app, Know Your Mobile added. Users can move the PIP around the screen and even adjust its window size.
