I really could not get on with 9.0GM it was so laggy and unresponsive for me, spotlight would stutter, multi tasking would stutter, apps would take a second to load and my battery life didn't even seem as great even in low power mode. 9.1 improved performance a lot but stutter still remained especially in the multi tasking window unless i turned off transparency and I even had a few bugs such as apple pay opening up randomly, even while walking outside and the phone is locked.
Gone back to 8.4.1 and it honestly feels like a different phone, everything is so responsive, lag free and feels like an expensive device again. iOS 9 to me just feels like my phone is years old and Apple is nudging me to upgrade to their new product with the "60% faster" processing speeds.
I prey that iOS 9 will become like 8.1.4 after a few patches, but until then I just cannot make the leap and will stay on 8.4.1 for the foreseeable future. If anyone is having any troubles similar to mine I simply recommend you do the same, hopefully Apple will catch onto the low adoption rate of 6 plus owners and below (if lower phones are having trouble, I don't think as much) and they might focus a bit more on performance in future incremental updates and our phones will feel snappy again. Fingers crossed : )
