Glide is pretty good on battery. I would say on days I am using it a lot, it can last the whole day. But during my average day, I keep it plugged in at my desk at work.
I'm off sick today, and I've been using the phone a fair amount to keep up on work emails, and a bunch of random web browsing, all via wifi. Only made a couple calls, each under 5 minutes. It has been unplugged for just under 8 hours, and I have 43% battery left. Seems pretty decent.
I have no experience with the Skyrocket, but I've heard that LTE usage really sucks a battery down quickly. I read that on the review of the Google Nexus on VZW. Maybe it's not as bad on the Skyrocket.
