Until yesterday I was using iOS 8.4.1 but I updated my iPad getting knowing a good sign of this update in this forum. I was wrong . May be its better then 9.1 0r 9.2 but 8.4.1 is better then 9.3 in my view. Lot of things are changed well I know that but specially Battery life , fluidity, lagging Matters most 8.4.1 was great but 9.3 is laggy battery life is worst and app crashes. I want to suggest everyone who are still on iOS 8.4.1 not to update there iOS device now wait more days guys. I am having a terrible time with iOS 9.3 ☹️☹️
