I have been digging through the threads here for quite a few hours now looking to see what the consensus is, but please excuse making yet another thread if it bothers you. I've read the sticky concerning performance and features along with pretty much everything else here (thanks search). I'm just wondering how iOS 9 GM has been performing on the original iPad Mini and iPhone 4S. Both are equipped with the A5. I would really appreciate any feedback from people that own the devices and have tried, rather than third or second hand accounts. Currently I'm running iOS 8.4.1 on both devices with no problems. I don't need things to be lightning fast, so I guess that would be a good gauge of the speed I'm used to. They're definitely not lightning fast like back in the day, but the point is they're still usable and retain an acceptable battery life. I'm contemplating a clean install of iOS9 on both devices. Thank for any info.
