iOS 9 Can Temporarily Delete Apps To Free Up Space For Software Updates
iOS 9 will require just 1.3GB of storage space on any supported iPhone or iPad which is a huge improvement over iOS 8. According to reports, the upcoming version of iOS will also prompt, if necessary, to temporarily delete apps before installing to update.
According to 9to5Mac, developers running the second beta of iOS 9 (released today) have noticed that the operating system now prompts users to temporarily delete apps before applying an update to clear the necessary storage space.
The process is completely automatic, and once the update is successfully installed, iOS will reinstall those apps.
9to5Mac added that apps are restored without any loss of user data.
iOS 9 also allows developer to "thin" their apps, which means the apps will take less storage space on your phone, giving you more space for your media, photos, and other content.
