Many people do not know that the iOS system settings in the application of the reminder number means that the current system has available upgrades, of course, many people do not like to upgrade to the latest system. When the iOS device is powered up and connected to WiFi, iOS automatically downloads the upgrade file, and for those who do not want to upgrade, the downloaded OTA upgrade file may occupy a large amount of storage space and these downloads cannot be removed.
However, in Apple's latest iOS 7.1 Beta, users can choose to remove the upgrade files as they wish. This can save a lot of space. Users only need to open the settings application, and then navigate to the general-consumption, where the interface can see the iOS upgrade files, after entering the delete can be selected.
iOS OTA upgrade files can sometimes be very large, such as the iOS 7.1 Beta 3 OTA upgrade files up to 720MB. In previous iOS systems, users were unable to remove the upgraded OTA files that had already been downloaded.
