Some one did a battery test on GAF, and the results are quite surprising. I don’t think you require a NYKO adapter with this one folks, as the battery life on maximum can last upto 4 hours 29 minutes as shown below.
This is much better than what the PSP could accomplish, and considering the fact that there is no optical media drive in the Vita, it helps immensely when it comes to battery life.
Time was spent: Play UMvC3 from Game Card (including about 30 minutes of Online play)
Occasionally flipping to Web Browser for quick look-ups, as well as Trophies app to check trophies (game kept running in the background, obviously)
Full to Death: 4:29
Warning notice came on at: 4:11
