When iOS 9 is finally released to the public this fall, it will come with the ability to save almost any type of content as a unique PDF file. Any iOS developer who has ever worked on a third-party app that has a requirement to render any kind of complex content to PDF will understand how difficult it can be. The PDF file format can be unbelievably difficult and cumbersome to work with, which is why this latest feature discovered in iOS 9 is even more incredible than it initially looks.

The introduction of iOS 9 brought with it a number of feature additions and much-longed for functionality improvements. Rather than reinventing the wheel and attempting to serve up a whole new set of core features, iOS 9 exists as more of a stepping stone for what is to come and attempts to stabilize its core offering with a number of stability improvements that should make the whole experience more pleasurable across all devices. iOS 9 does however, introduce one very impressive little feature that should make a difference to a lot of users - Low Power Mode, which is designed to save battery life by reducing the performance of the device and preventing consistent background activity.
