With AS? Yeesh. Mine (previous gen) will drain in about 2 hours with that or PyCharm open. IntelliJ stuff is super power-hungry unless you put it in power-save mode (and then it's not even as useful as a "plain" editor like sublime text or something).

I mean, I like all the power-hungry features, and I'm usually plugged in - I'd prefer they keep adding useful things rather than worry about my battery. But it does hurt at times :)
