Apple spent two hours at its Worldwide Developers Conference, or WWDC, updating us on enhancements for mobile devices, computers, the Apple TV set-top box and the Apple Watch. Apple’s WWDC keynote was so full of new announcements for the company that executives seemed to be struggling to keep up in making sure that there was time to cover everything.

iOS 10 at WWDC 2016

The recently revealed iOS 10 is full of new features that Apple did not have time to cover at their WWDC keynote. One of the most notable features on the new operating system is a “storage optimization” system.

Never run out of space again

Specifically, this new feature allows iPhone users to help free up storage when its running low. Users can instruct their phone ahead of time to delete a pre-determined amount of music that hasn’t been played in a while. So, when storage is beginning to run low, the phone will automatically delete that pre-specified amount of music in order to free up more space.

According to MacRumors, iOS 10 users will be able to instruct their phones to delete music in increments of 4GB, 8GB, 16GB, or 32GB. This feature is especially useful for users that have iPhones with only 16GB of storage, an amount that tends to fill up quite quickly.

Apple’s iOS 10 features many improvements

This feature will prove incredibly useful for those users that tend to keep their smartphones full, whether it be with a sizable music library, lots of applications, or a bunch a space-consuming 4K photos and videos. With the growing popularity of Apple Music, Spotify, and other music-streaming services, one can imagine that the amount of users that rely upon their smartphones for local music storage is a lot less than it used to be.

Beyond this useful feature, Apple’s iOS 10 promises to bring a handful of new features for your iPhone or iPad. Some of these new features include an updated Messages application, an improved, customizable lock screen, a brand-new Photos application, a vastly-improved Siri, a more efficient and useful Maps application, and Home, Apple’s new hub for all of your HomeKit-enabled devices. iOs 10 is shaping up to be the best mobile operating system yet.
