GP Editor, Marcus Estrada writes, "In case the news hasn't gotten around to you yet, the PS Vita is touting a lifespan of approximately 3 to 5 hours. That is, of course, if players remember to turn off wi-fi and bluetooth functions throughout their play time. Watching a movie fares a little better with 5 hours of battery life and up to 9 if all you're doing is listening to music with headphones on.
But since I assume most people have already found their standard device for music playing the biggest numbers to focus on are 3-5 hours. When the 3DS was found out to have similar gameplay hours it was a big deal-breaker for many. I have a feeling these estimates will also lose the Vita some potential customers."
