Apple has a new feature in iOS 9 that will make it easier to update your handset to the latest version of iOS if you have limited space left on your device.
The new feature in iOS 9 will automatically delete apps on your handset to free up space to install the software update, once the update is installed, your apps which were deleted with be re-installed on your device.
This sounds like a really useful feature in iOS 9, especially for owners of the 16GB iPhone and iPad who may not have enough free space to install a software update.
Apple also has another new feature in iOS 9 to make sure that software updates use less storage on your device, they have reduced the size of the OS installation significantly. iOS 8 took 4.58GB of storage space, where as iOS 9 will take up just 1.3GB of storage space.
