iOS 9 Space Savings
At WWDC when Apple unveiled iOS 9 one of the features they highlighted was a reduction in the upgrade free space requirement from 4.6GB to 1.3GB.

66% of my customers on eligible devices have at least 1.3GB of free space. This compares to just 37% of users who would have immediately had sufficient space at the old iOS 8 requirement.
iOS 9 is implementing some changes to make things easier on owners of 8GB and 16GB iPhones and iPads. We’ve already taken a look at App Thinning, a collection of technologies that will reduce the amount of space downloaded apps take up.

Today, the company sent out its first update for the iOS 9 developer beta, and iOS developer Kaleb Butt noticed yet another feature—if you don’t have the required free space, the operating system will offer to delete apps to make room for the update. It will then automatically re-download them when the update is complete.
Deleting an app from your phone or tablet normally takes all of that app’s saved data and settings with it. Presumably, Apple has either devised a way to keep that from happening, or it’s using iCloud to backup and restore your data along with the app.
