iOS 9 Beta vs 8.3 on iPhone 5 HD

June 8th 2015 Apple announced iOS 9, and released what they call Beta Pre Release of iOS 9. iOS 9 runs on all iOS devices that was able to run iOS 8. So also the iPhone 5. So lets compare it to iOS 8, and to iOS 8.3. Music Late Night Snack by Gunnar Olsen The video was put together under what was very bad circumstances. In a hotel room, non existing lightning, 0.7Mbps upload speed. So could have been better. iOS 9 Beta 1 seems to run pretty good on the iPhone 5. It is a bit behind in the boot process, but not much. And over all performance seems very good in most of the apps. Unfortunately I am not able to run Geekbench, Octane or Sunspider as non of the seem to work on iOS 9 I am hopeful that Apple will make iOS 9 even better in the beta releases to come.
