ringke stuff looks very nice... i wish they had a kickstand option... i really like my VZW kickstand holster but do not like that the corners are not protected.
I had a Rearth RingKe case on my Nexus S. They're similar to silicone cases but tougher, but weaker than tpu cases so they moved around alot especially if you put the phone in a pocket. Guess that's the trade-off for making them "the slimmest of them all".

Umm, the Ringke Slim isn't the same kind of case as their silicone case. It's like a barely there case with the top and bottom all covered.
I wonder if they fit/make a version that fits the lte extended battery?

Hi,
Our design team made the case to fit both the GSM/LTE version of the Galaxy Nexus phone. They made sure to take into consideration the .5mm difference between those 2 device. Our case will fit these 2 device very snugly.

Do you know if they will fit properly with the extended battery back on the LTE version (adds roughly 1mm to the back over the battery. Camera section is .5mm or less)

Thanks KrazyMonkey, that help me out.
Yea I talked to the same guy (the only guy?) and he said the same thing to me. That the case will fit both versions, but not with the extended battery.
Also if you look at the actual pictures, it shows the inward curvature for the standard cover. It appears they would have to make a separate case entirely just for the extended battery cover... which probably wouldn't be very profitable.
I know some people use the standard battery cover with the extended battery. I'd be interested in testing to see if this case would fit in this setup. Or since the case covers the entire back, what about going backless on the battery door?
Rearthe are the only silicon type cases I would ever buy. For some reason they feel really good in the hand.
looks really nice. i might jump on a black one. wish they made a matte version to help with grip instead of the high gloss.
They do make a matte case, and it looks awesome:

perfect. thanks
I liked the Black Matte and the White, personally.
I like my cases to be a different color then the phone itself to prevent people from saying, "wow thats a brick". I try to make it obvious thus not to fool the sheep.
Mmh, would totally sport the white one if it fits the extended.
wish the slim had a kickstand

the matte black is awesome looking. i wonder if it would fit if you didnt put the batttery cover on with the extended battery...?
Just bought the extended battery at Verizon for half off, also walked out with the Incipio double case. This case feels tough and sure can take s beating, great for outdoor work and kids dropping my phone. But this case is a little too thick for my liking.
But on weekends or going out would like a second thinner case. What thin cases fit the extended battery ? Anything like the Feather or Rearth slim fit ?
Sent from my Galaxy Nexus using xda premium
I just use ghost armor full body, and then I use a belt clip pouch that I drop my phone into. It is the slimmest option, I protect the whole phone from scratches, and I can keep it on my side. I'm not really worried about dropping it, because even with a case if you drop it in the right spot, you will end up with a broken phone. That's what insurance is for. At least that's my opinion. I hope this helps.
I just picked up the Diztronic case below and it fits great and doesn't add much thickness to the phone- nice and thin. I don't have my extended battery yet but per the reviews this case fits, just a little more tightly which is fine with me.

+1 on the Diztronic 3rd revision case. I am running it and I love it. I have 3 other cases and this is now my daily driver. You can even leave the extended battery cover on too. I use the Incopio when I need extra protection.
Also a big +1 on the Diztronic rev 3 case. Full access to all controls, full protection yet thin. Just about perfect as far as cases go and I have tried a few.
Diztronic has very upstanding customer service to boot!

I've been bugging Rearth about making their RingKe case to fit the Verizon w/ extended battery. This case has been getting a lot of accolades here...
With the Verizon extended battery going for $24.99, it should just come standard with the phone. At such a cheap price, and only adds like a business card extra thickness it is so worth it. Plus you may get up to 2 extra hours on it over stock.
Point being, with extended battery so popular, I would hope case companies realize this, and pump out cases that are officially designed for it.

My local Verizon store didn't have any in stock but they ordered it for me w/ free 2-day shipping. Still $24.99
I went into the biggest Verizon store in my area, called first asked if they had the Nexus extended battery, they said YES, and tons of accessories too. Go in there and they said the battery is 50% off, they had like 4 on the shelf. Just call the largest Verizon store in your area, I am sure they stock them.
I am using the phone today with no case, crosses fingers The Incipio 2pc case was just way too bulky for me, felt like a my old EVO 4G which was a giant. Back to caselsss and this phone looks awesome, the gray color makes this phone looks stealth, like something a pilot from F-22 Raptor plane would have in the cockpit I just want a razor thin case to go around this now.
Oddly enough I tried the High gloss silicone Verizon case and its is really nice. feels thin in the hand
I use the SGP capsule case. Its clearly designed for the GSM version because my Verizon + extended battery keeps the lips from grabbing the edges all the way.
But the phone is on there and not going anywhere. You'd have to really look at it to see what I'm talking about.
I'm still waiting for something specifically designed for the Verizon with extended battery.

Hopefully we get some news soon from the big case companies
Does anyone know if the Diztronic case works with the GSM Galaxy Nexus with an extended battery?
The best case I've tried period that also works with the extended battery is the Case-Mate Pop case. It was recalled initially due to a lack of clearance around the micro usb port. In about another two weeks they'll have the second revision out and it will be my daily driver.
I've tried the Case-Mate Tough Case, the Boxwave Active, the Boxwave Slim Rubberized Shell Case, and the Seidio Surface. The Pop case sucked less than the rest and fits the extended battery with good protection and minimal bulk.
can't comment if it's the thinnest, but it fits and looks good.

If you're looking at the OEM extended battery, it barely makes the phone thicker. A silicone case can stretch already, it'll fit just fine.
i've got the extended battery and silicone case from verizon and it all fits fine. with the silicone case you can't even tell which batter or back case is on besides the slight weight difference.
I think I was looking at the 2100 can't remember exactly somewhere around there though, will I notice better life with that over the stock?

You are looking at 10-15% increase in battery life because the size of the battery is not that much bigger than the original one.
It's like an hour+ for me with moderate use. I'm saying this based on my use, not any reliable testing, so don't quote me on that.
Basically, it will be longer but don't expect a huge improvement.
Thank you

I've recently gone ahead and purchased two extra batteries (extended higher capacity versions). One 3300 mAh and one 4300 mAh. They both come with their own special (larger) battery back cover. This in turn makes the phone much thicker and no normal case or protector will fit anymore. I've looked everywhere and just can't find any larger cases.
Has anyone found or know where to look for larger cases that will fit S3's that have extended batteries? I really do need to find something.

I think you are looking for what is called a Power Bank rather than just an extended battery:

This is the one I am considering.
I've posted a few pics below. The only back cover that I could find with the Anker 4400 was blue so that's what I have on there. Can't really tell with the cover on. I might spray it with some white if I don't like it. I have a size comparison with my wife's iPhone in a Speck case. Not much thicker. I'll be carrying this setup around SXSW next year.

Sorry for the late reply, yes it does fit. Picture attached! Fits pretty good, is not loose by any means but it goes in and out as it did with the Surface Case for the stock backplate and battery. It goes in all the way to the bottom and the top spring clip holds fine.

My phone is the Verizon Galaxy Nexus i515 and I've had the red Seidio cover for a long time. It came with a clip holster but the clip broke after 2 days. Got another holster and it broke again in 6 days. This was just from slight/small snags.
Basically I'm looking for something that can hold up against small snags. Also has all 3 combo (good rubber case/kickstand/clip holster).
This is something I'm looking for... only downside to this one is it doesn't come with a clip holsters. There's no indication, even on "what else user's bought after buying this", whether any clip holster will fit this particular brand. Link below...

I like the thickness of it and how it has small covers for the USB port and headphone jack. It also has the kickstand.
Does anybody have this particular one and have a clip holster with it? If you do, which one fits with this brand? If not, is there anything exactly like the link above with all 3 combo?

Probably not. These are for stock only. I think I saw a Seidio case awhile back that had options to accommodate a bigger battery door. Seidio and Trident are my 2 preferred cases but I've never looked into one for bigger batteries cause I've never had an extended battery before.
