[AC Question]

What drains my battery on Nexus 5?

If you scroll below the graph in Settings - Battery it will list the heaviest in order.
Music stored on the device should not normally use excessive battery afaik, but if you rely on Google Music or streaming especially on a bad signal, that would be a killer I would guess.

And if you keep the screen on when you're listening to music that would make it even worse - the screen is a big battery user. (Turning the volume up all the way whhen playing music over the speaker can also use a lot, relative to using headphones [most phones cut the maximum volume way down when you use headphones, so it uses less power as a side-effect - the main reason is to keep you from needing hearing aids by the time you're 45].)
