iOS 9 incredibly slow
Since upgrading to iOS 9 everything on my 5S is running incredibly SLOW!! What is wrong with this version of the OS? Also see notes on terrible battery life. Is there something wrong with the entire design of this OS at the core (kernel) level? It seems badly mis-programmed. No energy management, extraordinarily inefficient and slow and clumsy. This is probably the worst iOS upgrade I have seen in YEARS. Has anyone else been having the phone slow down so much? Searches now take minutes instead of seconds. Almost unusable. What did they do wrong? and WHY?
