Apple recently revealed that iOS 9 is taking a page from the OS X's playbook. The company's latest mobile operating system will now give its users an option to install software updates at a more convenient time.

According to Apple Insider, the Cupertino-based tech giant has brought the automatic overnight update from the OS X to iOS 9.

"We're also changing the way software updates are presented to the user. Users will be given a choice to install right now, or later at night when they might not need access to devices," OS X lead developer Andreas Wendker said during the company's Worldwide Developers Conference in June 2015.

This new feature of iOS 9 will most likely be similar to the "Try Tonight" option in OS X, which instantly installs available updates between 2 a.m. and 5 a.m. or during times when Mac devices aren't being used. A dialogue post then appears on the screen, notifying Mac users that the update has been installed successfully. Mac users are also given the option to read the full patch notes of the newly applied update.

Furthermore, future iOS 9 updates will now come at smaller file sizes than before. From 4.6 GB for iOS 8.1, the free space necessary to install updates has been lowered to 1.3 GB for iOS 9. This implies that updates are quicker and more recurrent this time around.

"So we think this is going to keep pushing users to update quickly, and will allow you to keep focusing your energies on the latest version of iOS," Wendker pointed out.

It was reported in a prior Apple Insider article that iOS 9 will perform more efficiently and smoothly compared to older iOS platforms. Even so, iOS 9 has an added "Low Power Mode" option to further optimize an iPhone's battery life.

When an iPhone has only 20 to 10 percent of battery life remaining, users are instantly notified to switch to the "Low Power Mode." They can also manually enable the feature by maneuvering through the Settings app then tick the new Battery menu, wherein a switch for "Low Power Mode" can be toggled on.

Once the feature has been activated, the battery indicator on the top right of the screen will turn yellow, indicating that the iOS device is running at a more efficient state.

Apple's iOS 9 isn't two weeks old but is already en route to becoming the company's most-downloaded software update. Approximately 50 percent of capable iPhones have now switched to iOS 9.

"iOS 9 is off to an amazing start, on pace to be downloaded by more users than any other software release in Apple's history," an executive of Apple's marketing branch expressed via Wired.
