That's a plus...
I'm probably gonna get the new iPod Touch but i was curious how well the battery life was specially that it is using LTE antenna. One of the things that i never like about android was the overall poor battery performance in just about all of their devices. Given that a lot of it has to do with the kernel and firmware you are on.
It should do fine. I've had the 2nd gen, 3nd gen, and currently own the 4th gen iPod Touch. I have absolutely no calms about any of their battery lives at all. I listen any from 1-4 hours of music, and watch maybe about 20-160 minutes of video on my iPod Touch daily and (depending on the screen brightness) it only loses anywhere from a quarter to half of it's battery life.
As long as you know/learn how to manage battery life, you shouldn't run into any problems.
