QT with the Vita on the floor at TGS, but battery life is hard to judge when you can't take the device away with you. Back at our earlier hands-on in June we were told that longevity should be on a par with first-gen PSPs, which were all rated at 4-6 hours and -- with the PSP-1000 -- achieved around 3.5-5.5 hours in real-world tests. Now though, Sony says the Vita has just enough juice for 3-5 hours' gaming. We need to play this thing to death before we can be sure, but this does sound like a potential 15-25% drop in minimum play time. Do we care at this point? Not particularly. We're too busy salivating over this.
