Seidio shows off 3500 mAh extended battery for Samsung's Galaxy S III

Running out of juice on your Samsung Galaxy S III? After an extended battery? Well, Seidio are here to your rescue with an extended battery for Samsung's flagship smartphone. The stock battery in the S III is just a 2100 mAh battery, but the S III is super-slim, after all.

If you want some extra juice, Seidio have a 3500 mAh extended battery that straps to the back of the Galaxy S III, but is it a little too thick? If you're like Fergie, and love your hump, your hump, your hump, your hump... then you should be okay with a little extra junk in your Galaxy S III's trunk.

I'm guessing with this extended battery from Seidio, you should definitely get two days at full brightness on the screen, and full use of the features of the handset itself, such as GPS, Wi-Fi, without running out of battery and needing a charge.
