I got one of those 5000MaH cases off of eBay and like anything made in China I'm skeptical about the claims of actually being 5000MaH. It charges OK but it discharges quickly and oftentimes I see a message saying that the phone is drawing more power than the charger so it's actually losing power as I charge!
I saw the Mugen for $89 and while it's super-expensive, hey, if it really works as advertised I'm all for it.. Can anyone please comment on their battery usage/charger strategy (and yes, I know all of the tricks, I just want to know if you are using an external device). If there's a bteer charging/case/device I'd certain;y appreciate knowing!!
