At their TGS 2011 press conference, Sony announced that the battery life of PlayStation Vita will be in the 3 to 5 hour range under normal gaming usage. This was much lower than most gamers expected and has since created a bit of a backlash online with heated debates raging.
In an attempt to quell the concerns of gamers, SCEA Worldwide Studios President Shuhei Yoshida, has confirmed that the company will be offering an external battery option for the PS Vita.
It will extend the battery life beyond the current 3-5 hour range. Right now little is known about this add-on device, but expect more details in the coming months as the December 17th Japanese launch draws closer.
