The PS Vita’s Battery Life is OK
The PS Vita‘s batter isn’t as good as the iPad’s, but it’s a smaller device, so I guess that’s all right.
The newly released spec sheet for the PS Vita states that the handheld’s battery will last for 3-5 hours while playing a game while not online. It will last five hours while watching video. It will last nine hours while listening to music in standby mode.
It’s not ideal, I don’t think, but it sounds better than the 3DS.
