Users of the new iOS 9 will be asked if they wish to delete mobile applications in order to free the space required for the upgrade. iOS 9 will then auto-select the apps marked for temporary removal, as revealed by its developers and testers. Apple is using this to assist in averting last year's iOS 8 disaster, when owners of low storage capacity iPhones and iPads couldn't install the update. Many had to manually remove apps, photos, videos, music and other data to clear enough room for the sluggish iOS 8.
Apple has stated that it plans to reduce the amount of space needed to install iOS 9 from 4.6 gigabytes to 1.8 gigabytes this autumn — a 72 percent decrease. The company has also launched a new multifaceted technology called "app thinning," which enables third-party developers to create apps that use most of the device's features, occupy minimal space and accommodate future updates. It will also allow for faster downloads and leaves more space for other content for the optimum user experience.
OS upgrades generally require more space in order to properly install than they actually wind up using. This is due to the unpacking need for compressed files that are too large for its memory before beginning. These updates also generate large files, which are temporary but also written into storage, that contain copies of all the elements of the new OS. The iOS 9 will attempt to ensure that your device will remain in a working condition if the upgrade somehow fails and return the apps after using the space it needs.
If Apple cannot properly manage this upgrade and things go awry, reach out to MC Services for technology consulting and Apple support to keep your device user-friendly until it blows over.
