I just ordered the Hyperion through Amazon and the case for it as well. I'm amazed! Took this phone from one that I can barely make it through 12 hours with minimal use and having GPS, data and wifi off except when I MUST have it (i.e. at lunch) to a totally new level where I have all services running throughout the day and extensive use without a charge for 12+ hours. Should have expected it - the battery has the same capacity as the Razr MAXX.
In reference to the case... Meh... I had the silicone one that I bought through Verizon on day one of owning this phone and it was a nice one. Felt good in the hand, lasted nearly 2 years (still works but not on the extended cover) and protected the phone from my occasional oafish drop. The one I have from Hyperion feels cheap (I guess because it is...), but does its job - I've dropped it a couple of times and had no issues. Only real issues I do have is 1) this case covers the hardware buttons on the bottom. With EP1, EP4 and FP1, this wasn't an issue as the backlighting worked randomly at best. With the FP5 update, I've found that the backlighting appears to function properly and the new cover precludes that. 2) the charging port's cutout was too small for the charger. Initially, I just pulled the cover down and charged it that way but who wants that? UGLY! So... That's what a razor blade is made for... I cut the hole bigger (carefully!) and have had no issue since.
I believe that will be my solution for the covering the hardware buttons backlighting as well...
