Few days ago i upgraded my iPhone to iOS 9 beta for testing purpose but i have changed my mind to downgrade iOS 9 to iOS 8.3 after couple of days. before upgrading i was aware of iOS 9 is in beta stage will have bugs, but worst think is battery consumption by iOS 9 beta. Its consuming huge battery so I decided to downgrade it and this is how i downgrade my iPhone from iOS 9 beta to iOS 8.3.
