A: The short answer is that it depends on what you're doing. The longer answer is that Sony has stated that the battery should last around six hours. With simpler-looking games, like Lumines or Mahjong Fight Club, that definitely seems to be the case. But with more graphically intensive games, like Ridge Racers, the battery doesn't last quite as long. Based on our estimates and a few battery-draining tests, Ridge Racers seems to last somewhere between 90 minutes and three hours. Playing with the wireless networking switch flipped on will also further reduce your battery life. The system has an auto-sleep function that stops the wireless drain, but that switch is there for a reason. Turn it off when you're not using it.
How does everyone feel about this? This is not even with wireless networking turned on!
Do you think this will get better in the future, and if it doesnt are you still going to take the plunge?
Sony has stated that the more graphics intensive the game, the shorter the battery life. Its not like as the PSP goes on in life that games are not going to get more graphicly intensive. That only leads me to believe that this problem is going to get worse and worse. Who cares if I can play a 2D puzzle game for 6hrs?! I want to play ALL my games for the stated battery life, not just a select few.
