[AT&T Samsung Galaxy S II SGH-I777] gr8hairy1:
There's alot of photos, I know. But every question you've had about a Galaxy S II with an extended battery in combination with a Taurus bumper case is answered........ hopefully.

Ebay comes through for me!

On the same day I got the Taurus Aluminum bumper case and 3500mah extended battery!

Yes, the Taurus case was listed for the international version, but it fits the ATT SGH-I777 model.

Without any foam tape the phone wiggles a little bit (perfect!) though a little tight on the thickness, but it still fits. I hope to find a thin piece of silicone I can run around the edges before I screw the top on and leave it on.

*Update*

After applying the Ghost armor screen protector and sides, there is no longer any 'wiggle room'. Most likely I will use my dremel tool to widen out the case just a little. I don't want the shock from it getting dropped to go straight to the phone's frame. That plus the silicone layer I want to put between the two pieces of the Taurus case should turn this case into one of the better protection cases available for a phone using an extended battery door.

Unexpected good news about the Ghost Armor! It came with a small piece just for the lens glass. Nice to know that if I took everything off the phone, the glass for the lens would still be protected.

In preparation for getting this case I ordered from Ghost Armor screen protectors for the front and sides. It works out that it covers everything but the battery door. So everywhere the case touches is covered by a screen protector that has a lifetime warranty on tears and holes. Phone should be protected no problem. Even if it does cause wear after awhile, I can go into a Ghost Armor retail shop and have it replaced on the spot. After 20% discount code I found online it only cost $13.

And the biggest worry I had, will the extended battery door fit?

Fits and fits tight.

You got to work of to get it off. And looks beautiful with the Taurus case on. (Ok not beautiful, it is a big hump on the back) But the frame of the case helps blend it, not a lot, but helps non-the-less.

*Update*

Noticed that with the Taurus case on it it's next to impossible to get the extended battery door off. With the raised back it puts the slot for your fingernail to pop it off too low and the case comes up next to it. Stock battery door can be pulled off easily.

Wait, 3500mah battery for the ATT version?

Nope. The international I9100.

Well, but I've read you can't charge it using the phone.

Charges great.

Maybe the nonstop reboots was talking about plugging the USB into a PC?

Flashed using Odin with the extended battery in it!(ok that was dumb, but I forgot the battery was in and rumored(or certain ones actually did)have nonstop reboot loops when plugged in) I was high on seeing my phone could charge it and threw caution to the wind.

The phone charges it no matter if it's:

on, with screen on or off.

off and only displays the charging battery image.

plugged into a computer.

The only downside is the wall charger they included cannot charge the extended battery. The contacts are on the wrong side. Stock battery can charge because you can flip it backwards and the contacts can then line up. But the extended battery is too thick. Yes ironic, but really annoying. At least for now my phone seems to be able to charge the battey.

Here's what photos I do have.

What most people are looking for when they view this thread:

(Don't make fun of the quality of these first few photos, they were taken by an Atrix and it was trying as hard as it can, but 5mp is 5mp :)

Trying to show thickness of case and battery door:

(usb cord used for easy reference)

These next one shows the extended battery door is just over the thickness of the metal part of the usb cord past the Taurus case:

And this next two show the extended battery door is just under the thickness of the metal part of a usb cord compared to the bump at the bottom of the case:

While it may look like the battery door is a huge bump, and by itself it is, holding an Atrix up next to it, and it has no case save for a layer of carbon fiber Ghost Armor, the Atrix with no case is nearly as thick as the Galaxy S II *with* the Taurus Case, at the thickest point of the Taurus Case. With a normal case the Atrix would very likely be as thick as the Galaxy S II *with* the extended battery door:

(Taken with the Asus Transformer, apparently worse than the Atrix for close ups)

Photo of everything but my phone:

Charger and back covers

Taurus Case

Noticed near a couple screw holes what looked like yellow paint(something) showing through - hope that's not what it is:

Extended Battery

Why included charger can't charge extended battery

Difference between extended battery and stock battery

Depending on response I'll video review it and post it on YouTube and report back here about it.
