Of all of the details we know about the PSP, the battery life is the least known. Many have estimated the battery life at shorter than that of a Laptop.
However, reports in the October issue of Popular Science magazine suggest the PSP will play games for up to 8 hours before needing a recharge. It also notes that Movies can play for up to 2.5 hours and Music, 10 hours.
Sony has yet to confirm these figures.
