Yeah, what up with that, a 1800mah battery that is the same size as a standard battery that will fit without needing an oversized battery door adding thickness to the phone, I am also interested in this.
Anyone one got one?

 

i'[ve got one. it works well. but the verizon extended battery is definitely better. the 1800 mugen will give you a few more hours than the stock though.

 

can't say. i've really never measured to be sure but i just know i get some more hours with the mugen.

 

I just got the Mugen 1800mAh battery, so I thought I'd add to this older thread.

Today is my first day with it, but it is definitely better than the stock battery. I'd call myself a medium user, and after over 10 hours off the charger, I'm still at 74% battery. That would work out to be about 40 hours of battery life (more really, since a chunk of that would include idle phone time while I sleep). I could easily get 2+ days on this battery. I was generally running 24-30 hours (extrapolated, since I charge every night) on the stock battery.

So anyone looking for some extra juice without needing a different battery door, this is a great choice. Just don't follow the charging directions on the back of the packaging. They recommend charging/discharging the battery 3-5 times. Anyone who knows anything about Li-ion batteries knows that discharging them is about the worst thing you can do to them.

 

Uhhhh...

By the way, 15 hours off charger and at 63%, so still on pace for 40 hours.

The real test for this battery will be in a week when I head to Florida for 10 days. Being on vacation, it'll get more use, including a fair amount of navigation. And the big test will be when I play golf while there. I use Golfshot GPS and that can do a number on a battery. The stock battery would make it 18, but would be pretty shot by the end. We'll see how much juice the Mugen has after a round.
