If you’re waiting for Apple to come out with an iPhone with a removable battery, don’t hold your breath.While there are a bunch of power booster cases, there’s finally one that doubles as a removable spare battery.
The accessory comes from Third Rail Mobility, and doubles as a case for your iPhone 4. If you need some extra juice, there’s a rechargeable battery that snaps on the back.
Unlike most iPhone 4 battery boosters, this case won’t add too much bulk to your phone unless you slide on the battery.
The Third Rail System will cost you $89.99, but for those who quickly burn out their iPhone battery, it may be worth it.
