8.3 battery life, bluetooth connection and recommendation

8.3 with my new iPhone 6 works like crap with battery life. Bluetooth connection is screwed up with their update to my hearing aids as well...One thing that I have BEGGED for Apple to listen to is when you enter an address it should START with numbers since EVERY address in America starts with numbers. Just stupid that they don't and they haven't listened to me about this for years. What do we do for listening sake????
