Even though this battery offers a lot more power, this 2600mAh battery will only extend your AT&T TiltHTC or TyTN II by 4-5 mm and your hand will rest comfortably on the battery door which is included.

The door is made from a hard plastic with a smooth rubberized finish, so you will have a better grip of your phone and it will reduce scratches. The door also has cutouts for the camera and speaker which will give a better overall sound quality than the original battery door.
