iPhone users upgrading to the iOS 9 beta noted an interesting feature built into the new operating system. The OS will prompt the user to temporarily remove apps if it finds that there is not enough storage to complete the update. The removed apps will be automatically restored once the update has been completed.
iOS 9 is set to take up a smaller storage footprint than iOS 8 as part of Apple’s plan to reduce the amount of space its takes up on devices with less storage space. At this point, iOS 9 beta 2 only takes up 1.3GB compared to the 4.3GB of iOS 8. However, the update still needs to have enough space to store both the systems while the update is happening. The good news is that the temporarily removed app will retain all user data, which isn’t made clear during the prompt.
Apple is currently planning to be able to push out smaller updates for iOS 9, mostly to cater to customers who buy the devices will smaller storage space. The company needs to support older devices with smaller storage capacities owned by people who have likely used up all the free space with their accumulated apps.
