My battery consumption is right at 10% loss per hour. I recently completed a ride across Florida with the longest ride being 85 miles and did not recharge the phone until I got to my hotel room. If you're only getting an hour out of your phone, you're doing something very wrong.
I have this setup too. iPhone 6 + RFLKT and Bluetooth speed/cadence and HR strap. The longest ride I've done this year was 113 miles, and I had 40% charge on my phone at the end of it. This was before the release of iOS 9, where the battery life seems to have got even better. The only thing I do when going on long rides is to turn off mobile data. I don't handlebar mount my iPhone, it just goes in my jersey pocket, in a ziploc bag to protect against sweat/rain.
