Not trying to flame you here but where have you seen it "proven"??

I certainly agree there seems to be quite a few happy purchasers in these forums for the Hyperion battery and that's certainly great and I, myself just recently ordered the Hyperion battery as well, but let's put some things in perspective here...

* As tigerboom pointed out, DON'T expect longevity with the Hyperion battery. At about 1/2 the cost of the OEM battery and at the same time supposedly 2x the capacity...That should already be a strong indicator there's sacrifices going on. Then again, my smartphone lifecycle is about a year or a little longer anyway so if the cheapo batteries can hold up for that long then I'm golden!

* There's little to no regulation on how a manufacturer goes about rating their battery's capacity! I'd be willing wager that the Hyperion's rated 3800mAH is probably closer to the neighborhood of 2700mAH (give or take)...Whereas with the Mugens (being a very well known and renowned brand) is probably right at the rated capacity. Then again, even if the cheapo Hyperions are well less than their rated capacity but still well more than the stock battery? Heck that's still a win in my book!

* Don't expect great customer service on cheapo batteries.

All in all, give the quality batteries like the Mugen their due, but unless you plan to keep your phone for a LONG LONG time (cause that battery ain't gonna fit in your new one!) and need a rock solid dependable battery thats got a capacity to last until the next ice-age, them cheapo Hyperions will probably do the job just fine and not break the bank!

Got the Hyperion and so far so good. I get a full day of usage now. :)

mugen claims that they have longer battery life.
cheaper batteries have 100-200 recharge cycles and higher quality batteries like seidio or mugen have 400-600 recharge cycles.

I've placed an order for it and it's already shipped. Should be getting it within the next couple of days. Will upload some pics once I receive it.

why no pictures yet?? i guess they ve uploaded since then.
And its a decent looking backcover with a nice little stand leg for landscape view.
I wonder is it comfortable, i mean this stand, do you actually use it?

Are you serious? Only one day? my wife gets 3 full days with 4000mAh from mugen... something must be really wrong, unless you skype/video call on wifi this whole 24 hour day that i can understand..

The Hyperion is only 20$..... It's not like it's actually as big as it advertises. If anything it's probably only about 1000 mAh bigger than the original. Mugen are built for quality, which is why they're so expensive.

Take a look at this:

Basically every third party battery maker lies about capacity. Mugen, Seidio, etc...

even teh OEMs aren't quite at their rated capacity, though they are definitely the closest to what they advertise
