how do i keep the battery form drainng so fast
Screen brightness is one of the biggest drainers of battery life on any portable unit be it Cellphone or PSP / PS VITA.
Actually the biggest power drain in any of those devices is location services (GPS), followed by 3G/4G.
If you're on WiFi at home, be sure to turn off your 3G.
For brightness, just use the lowest you can handle for your normal viewing environment. You can always hold down the HOME button to change the brightness at any time if you need to raise it or lower it depending on the game.
