Sony recently revealed the battery life for the PlayStation Vita is shockingly bad. The handheld is expected to only last 3-5 hours on a single charge depending on what you do. To achieve the best battery life possible, you can’t have the screen at its brightest level and you can’t run other functions such as Wi-Fi and Bluetooth. Based on the type of games Sony has shown, gamers are expected to spend hours on a single Vita game. For those who need an extra boost (which is most of you) Sony will also sell an extendable PS Vita external battery.

Among the new information Nintendo released from its Nintendo World event from Japan is the expected battery life for the 3DS. The 3D capabilities the handheld possesses will take a noticeable toll on its battery. Once you factor in screen brightness and Wi-Fi connectivity, you’re looking at about three hours of minimal battery time out of the 3DS before it needs to be charged again.

It was only a week ago that Sony’s Hardware Marketing Director John Koller announced in a GameSpot video that the PSP-3000 (aka PSP brite) would have a shorter battery life than previous PSP units. Today (September 3, 2008), Koller issued a statement on PlayStation.Blog saying that the PSP-3000′s battery life will be equal to that of the original PSP and PSP slim.

In the latest statement, Koller confirms that the new, brighter screen will require more battery power, but that the system is being crafted in such a way that everything else will use less power. He goes on to say the PSP-3000 will last for between four and six hours if you’re playing games, and between four and five hours if you’re watching movies – just like the previous PSP models…
