when I'd run out of a S2 with normal battery, or I gave 5 stars. However, the mobile phone comes with a 2000 mAh battery while in the pocket, it just sits then extreme tension and bulges slightly at the back to the rear. I think in the long run is not good, especially if you often takes the cell phone to get out. Am now thinking on whether I return it or if I edit the interior rear side with NEM Dremel until it fits properly;)
Edit: After nearly 4 months (not taken more than once a week from his pocket, because I've been using it as a navigation system in your car) is now a corner then canceled. So who has a great battery had better stay away from this case.
