iPhone 6 hot and short battery life

[BethZac5]

My iPhone 6 sometime gets really hot when I listen music and the battery life is really short, like one song cost 1% battery.
What's the problem?

Go into settings and see what else is using the battery.

Hi Newtons Apple,
I have killed all other app in back ground. I just met this case for 3 times I think. Not all the time.

Next time it happens go to Settings, General, Usage, and then Battery usage. Even though you think all is shut down this will tell you if an app is causing a problem.

Thank you very much Newtons Apple. I will try this next time.
