With a great new, vibrant anti-glare screen comes a slight reduction in battery life. Such is the case with the new PSP 3000 model coming out. Initial reports and statements by Sony say that the average user will lose between 20 and 30 minutes of battery life compared to the 2000 model.

"Battery life will decrease by a small amount. It's about 20 minutes, maybe 30 minutes, and that's because there's a larger power draw with the brighter screen."
The PSP Slim (2000 model) currently offers gamers around 4.5-7 hours of battery life depending on a number of factors. Some of these factors include screen brightness and volume output.Source
