Whopping 4200mah Battery with NFC for the Galaxy GS3, which comes with a bigger back cover for the phone
As expected, it will increase your phone's size to be much bulkier, and there is only one supported case for it
If you need all that extra battery power, go ahead, here is the link

Yeah I had one delivered yesterday (pebble blue version). So far so good on extra battery life. It does add bulk but the extra thickness and weight is actually kind of nice.

I would get it but I wish it had more compatible cases other than that one by the battery company

if you buy seidios extended battery back cover it fits with this battery. Meaning you can use their surface extended battery case or the active extended battery case which offers the most protection out of any extended battery case and it has a kick stand I believe. Might cost you a chunk though
 
I like the slimness and like to have it in a case, so any places to purchase the battery that came with the phone? The 2100mAh?
 
everywhere. Cheap versions on Amazon and eBay and hundreds of other sites. Or you could buy the real thing from Samsung's website

And that is the reason why I went back to my stock battery. I absolutely loved the amount of extra usage is could get from using both of my extended batteries, but the lack of cases turned me off from them.

I ordered a Spigen case from Amazon as soon as I switched back to the stock battery. Can't wait for it to get here.

I actually ordered the 4200mah Battery and I found this case which seems to fit pretty well! Looks pretty sleek too. If only I can find one with a kickstand besides the expensive Seido one

This is my usage using the battery today. I really don't know if I'll ever get two days. Well my screen shot isn't posting. I'm 10%.lost within a hr and a half.

Its good to know that the y have these but I really don't need the extra battery. The stick one that came with the phone lasts me all day.

I have my 4200mah Bettery now
I have been using my phone all day, and currently watching and almost halfway through "The Odyssey" movie and full brightness and the battery refuses to go down quickly! I Love it!
 
Just got my hyperion battery.

It says initial charge should be for 12 hours. Does that mean I put it in the phone and charge for 12 hours or put it in and drain the battery to 0% and then charge for 12 hours?

I originally bought it so I could get through work on one charge, but it might come in handy with FrankenStorm coming.

I've heard that you really don't need to do that. Because the batteries aren't like the old flip phones and don't need to be conditioned. I have the 3800 for my nexus. I have two. I conditioned the first time. And the second oneI charged it til 100%. Both work the same. Also one is trexcell and the other is the Hyperion. So u can if you want, bit you reallly don't have 2
