Then, I charged it to 100% right before leaving work. It's now been 1:20, and I'm still at 98% having used a few times (not much action) since then.
The GPS will likely only make a significant difference if you're using a program that requires it. I don't recall the program on my old Android, but it would suck a lot of power if you left the GPS on.
