Grip the back cover of the iPhone and push upward about 1/8th of an inch to remove the back cover from the iPhone 4S.

There is a cover over the battery connector. To disconnect the cover, locate and remove the one Phillips screw (#00) that secures it in place. When the screw is removed, use the spudger to gently pry up the connection releasing it from the motherboard.
Be careful not to lose the clip secured by the Phillips screw, it will be needed for reinstallation.
