I've been using my 6 for about a couple of weeks and I'm shocked at how lame the battery life is. I guess it's the price you pay for a bigger display and faster processor? I was using an iPhone 4 and had installed a new battery in it. I got at least twice the life out of that battery. That's why I still carry it around. Unfortunately I now have to use it as a backup for when my 6 dies. And I'm not even listening to music! I've basically had to turn off ALL iPhone 6 features since they suck battery life. App background refreshing, GPS etc. This is my second iPhone 6 as well. I've decided to return the 6 and wait for a 6+ only for its battery. So much for having a one handed phone I can rely on for a day.
