We've had plenty of 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.
