"In my experience, when something advertises that its battery life is between eight and ten hours, it's flat-lining in six. The standard battery on the PSP claims to work 4-6 hours depending, of course, on what you're using it for. So I wasn't necessarily surprised when the screen was on full brightness, the volume on max while playing multiplayer games using Wi-Fi (in other words, throwing as much abuse at the battery as possible), it lasted a little under three hours. I was actually kind of impressed."
