If you have tried the incase powerslider, chances are you ran into the same problem I and many others did, namely, while it did double battery life, it all but ruins 3g and even wifi reception to the point where the phone is almost unusable with the case on, that was my experience, and from what I've read others' as well. I don't believe the redesign of the powerslider did anything to address this specific and in my opinion, glaring issue. So, here is my question. Why hasn't incase, or another company designed something just like the powerslider, but designed the battery in such a way as to not block the phone's antenna? Which leads me into my next question, how would it be done, ie. keep the design pretty much the same, but, not interfere with reception? All I can visualize in my head is a lithium battery that instead of being a solid rectangle, is sort of like a rectangular doughnut, in other words, the middle of it is removed, or whichever part of it is covering/blocking the phone's antenna, can a battery be made that has enough capacity without covering up the entire back of the phone? Not knowing exactly where or how large the phone's antenna is, I don't know exactly how this can be done, or where the battery should be displaced to allow a window for signal to get through the back of the phone, but surely it can't be that hard? So, my questions are, first, has any company yet discovered a way to make a good, protective case, like the powerslider, that does not interfere with reception, and if not, why not? Your thoughts are appreciated.
