What is in the package
The battery comes with a replacement back door, since it is about twice as thick as the original. The door snaps on securely, leaves the camera clear and avoids reflecting the LED flash.
Fit and design
- The bottom of the phone stays unobstructed, so it still fits a Galaxy S II charging dock, which is rare for extended batteries.
- The phone is still slim enough for a belt holster.
