Two weeks after the previous releases, Apple on Thursday offered new, fifth betas of iOS 9 and watchOS 2 to developers. The iOS 9 beta is now required in order to use the latest watchOS 2 beta, and may address some of the long list of serious bugs developers have reported so far, such as random reboots, poor battery life, inoperative Bluetooth connections and other problems unresolved or introduced in beta 4.
