I thought the PSP Go might have better battery life than the current PSP since the PSP Go doesn’t power a laser. Unfortunately, that’s not the case.
The European PlayStation Blog points out the PSP Go has three to six hours of juice for games. Movie playback lasts approximately three to five hours. When the PSP-3000 came out John Koller, Director of Hardware Marketing, said the PSP-3000 has four to six hours of life for games and four to five hours for UMD videos.
Sure, that’s only an hour less of Crisis Core, but an hour when you’re talking about three to five hours of total battery life is notable.
