Crazy 3800mAh battery - should I try my luck?

So I've seen a couple of eBay auctions for 3800mAh GNex batteries. I can't post the URLs here as links because I'm a too new here ( :-( ).
The price is right and the promise of 2x the rather modest battery life of the 1750mAh battery in my GSM GNex is hard to resist.
What does everyone think?

It will double the thickness of your Nexus, and has a cheap (and probably) non-ergonomic back cover.

I wouldn't it get as it has no NFC (Near Field Communication) antenna in it. Also, most of those cheap Ebay batteries are not rated as advertised.

Try it and get back to us. I'm trying the 2300 and 1900 mah GSM cheapo batteries from ebay and getting back to the community afterwards

Yes - that's one of them. Do a search for i9250 3800 and you'll be able to find the other.
Admittedly the back case doesn't look as nice as the stock one, but what I'm really worried about is my phone exploding in my pocket and injuring me. Or at least destroying my $600 phone.

This manufacturer has had a lot of similar units for various phone models.
I had been using a version for the Samsung Infuse 4G with no issues for 4 months or so, so I would expect the same for the Galaxy Nexus variant.
One thing to keep in mind however: these batteries DO NOT have the NFC Antenna in them, so you will not be able to use Google Wallet or the Android Beam options.

These batteries are actually are from a Droid Charge. I read it one galaxy nexus and i have tested it myself. There are some Droid Charge 3800mAh battery with good reviews you. But you still will need a back cover and will have NFC.

$11.89 for cover & battery seems fair for 3,800 mAh:

Just be aware that all batteries are not created equal, especially from china. Surefire batteries, specifically 18950 batteries used in high end flashlights. They just put a new shrinkwrap and recharge old batteries. Good or bad, it dont matter at least they look new. They advertise 3000mah, youd be lucky to get 2 of 10 that are 2000mah.

Well, given the price, I'd have to say it's going to suck, but then again - it's not that much money to try it - if you really need something that huge.
I would try it, but I'd rather wait for a package that comes with a case. In the end it's a $725 device that I don't want ding'd.

After trying a lot of these batteries on most of my phones over the years, I say that if it aint sold by the phone manufacturers, save your time and money.

I think you're thinking of 18650 batteries. Flashlight forums usually rate the surefires rather well compared to the others.

I'd say give it a try. those are generics. back in my multiple battery craziness days, i had 2 of those same generics for my Thunderbolt. they were ok.. at least they actually worked anyway. didn't use them long enough though to comment on longevity.

Yeah, I know what you mean about multiple battery craziness lol. I have two generic batteries for my Thunderbolt AND a huge Seidio extended battery along with my OEM. The generics work just as well as the OEM.

Generally any battery for your smart phone under $40.00 probably isn't rated at what it says it is. I've managed a fairly good collection over the years. You definitely get what you pay for when it comes to them.

verrrrrrrrrrrrrrrrrry interested! let us know

Also found it at Amazon UK for the GSM version:
http://www.amazon.co.uk/QCell-Samsung-3850mAh-Extended-Battery/dp/B006SKHIKG/
Might end up buying one. ¿Any cases that will fit it?

Great find! I've searched daily for one of these. Thanks very much for sharing. I need one for backcountry GPS use and changing out small batteries always screws with settings. For $20 with cover and Prime, I'm jumping on it!

Just a quick warning that these are not NFC compatible. Personally, I don't use it, but it may be important to others.

Battery came very quick, very fast delivery and used for one day
I'm extremely impress with the performance of this battery. Typically on an average day, I only get at maximum 4 hours of battery life thanks to the 4G connection, now I can go on for a whole day without looking for a charger! will continue to post results as I use this more
Also will like to comment on the back cover. It has the Hyperskin texture just like the original case. Makes the phone just as grippy as the original case, the cover also provides an ergonomic contour for holding the phone properly. With the original cover I find it a little bit too thin to hold. Along with the hyperskin texture, this thing does not slip at all.
Overall excellent build quality and good lasting battery. This will be my main battery going forward

I don't trust Chinese batteries because of an experience I had with a Chinese battery I had for my DX2.
I will stick with my expensive Seidio batteries from now on. lol

seidio is like 4 times the price of this battery. I tried seidio before and although they are good, i find phones obsolete too quickly to warrant on an expensive battery with similar increase of batt life

At that price it's hard not to pass up. There are very few times I need such battery life but tournament weekends and occasional outings for events definitely would warrant this.

Just ordered one for flights with an external charger. Hopefully everything works out well.

Gonna give the Anker Multi-Purpose Universal Rapid Cell phone Battery Charger for Samsung: Galaxy Nexus one a try. Can't post a link for amazon since I don't have enough post.

Btw, just a heads up to you all.
If you look at all the posts of the OP, he seems like he is banging the drum for QCell batteries.
Just a FYI.

OP probably is affiliated with QCell in some way.

Battery vs Stock vs Extended Verizon
I'm worried that the cheaper cells used won't hold their charge after xxx charges. It happens all too often. I think all of us have had this happen to them on one phone or another. At that point might as well buy overpriced Seidio.

That picture makes it appear that the extended battery nearly doubles the thickness of the phone. I'm using the Sansung extended battery and while it adds a nicely needed "heft" to the phone that keeps it from feeling too cheap, it doesn't add a lot of thickness.

I ordered a GSM one from Amazon UK, there's not much price difference with the chinese ones on eBay and, although the battery might probably come from the same or similar place, the case seems nicer and if anything goes wrong I'd rather ***** Amazon customer service than some random eBay seller.
Will keep you informed, although I don't have the official extended battery to compare with.

I just got mine in today. Definitely is thicker and kind of looks like the seidio extended battery but it actually matches the color and texture of the original battery. I am coming from the verizon extended battery and am charging up the new one as I type this so I'll report back after I use it a bit

Extended Batteries... Mugen vs Original Samsung

I am looking to keep my white GSM Samsung Galaxy Nexus naked as the bulk is just too much, and I need as much comfort in my hand as possible...
That being said: does anyone want to chime in on how the Mugen extended battery is performing compared to stock and/or the original Samsung /w battery door?
I have the original samsung extended battery, but no white door to put on...
Thanks guys.

One thing to note if you are buying a replacement battery... the NFC antenna is built into the battery. If this is a feature you use, make sure your new battery has it.

I am waiting for my 4000mah mugen battery including nfc. But would also love the pogo car dock.. Too bad in does not fit anymore with the New battery..

Both will give you about 80% of the capacity they put on the label. Everyone else will give you much less than that, 70% tops, and often half or less.

I think these cheapo $10 3800 extended batteries on ebay are pretty good if you come in with the right expectations.
Yes, we know they aren't 3800, and are closer to 3000, but that still gets you about 1000mah more than the stock battery.
Yes, they lose their capacity over time more quickly than a genuine battery, but you should treat these types of batteries as disposable.
Buy one for $10, use it for 6 months and then buy another one.

The only thing that keeps me away from buying them is that batteries, in a general way, are pretty dangerous for the environment, specially cheap ones. And I wouldn't like to make that kind of waste buying several batteries.

it adds a little thickness but not that much, actually you won't notice any difference while holding it and using it with one hand
the only downside is the back cover, I don't know what its called in English , but the tips thats go in the phone body can easily be broken
( look at the image i circled the thing as an example - the photo not mine )

Could I trouble someone to measure the thickness of the Seidio 3500 for GSM? Looking to get one, but want to see if I can do a little modding to fit it in a case without using that unsightly back door. From the comparison pic above, it seems to be a hair over double the thickness of stock battery. Correct?

Review: Seidio 3500mAh Super Extended Life Battery and Surface Extended Combo

Thanks for checking out my review. I have a lot more bigger pictures of this set up on my blog.
http://chrismchoi.blogspot.com/
Please check it out. Just getting it started. Please hit thanks if you find this informative or helpful and I will keep trying to review products for you guys.
We've all fallen in love with our Galaxy S III. What would have made our phones better? Extended battery life. Thanks to Seidio, they've provided us with the solution. I was relieved to find that the rubberized back was an added bonus. There has been much interest in this finish due to the sleek design of the factory back.
If I ran the numbers right it, the battery has a 40% larger capacity while still maintaining the sleek design.
The total weight of the extended battery and case came out to 6.53 oz. Factory weight was 4.76 oz.

}
The SURFACE Extended case is the standard SURFACE case in the Seidio line up. Straight and to the point. It's the minimalist case. It covers up the corners. It's nice and thin.
Battery installed.
The hump in the back made the phone much easier to grip. The hump fell right into the palm of my hand. It didn't slide around like it did without it.
Fitment was dead on. I've been trying different back covers and the Seidio cover fits the best out of all the aftermarket covers I have tested. It's even all around without leaving any open gaps.
The SURFACE Extended case stays snug. You don't have to worry about the phone slipping out.
I was glad to see that Seidio took the time and made the case fit. You can see how accurate the openings are for the camera, speaker and flash.
The standard Seidio clip. Same as always. The top mechanism is still the same design we know and love. You never have to worry about it wearing down and cracking. It has the same spring design.
Conclusion
I'm in the wireless industry, so the the extra life is put to good use. The numbers do not lie. This is moderate use throughout the day. Maps was triggered by Google Now. I'm sure it would have last much longer without it. This would equate to almost 72 hours without a charge. I apologize I stopped at 49%. I will redo the test once I am settled back in. It's highly impressive from how it performed and I am content in this product.
MSRP: $69.95 for the Seidio Super Extended Battery available at the Seidio Online Store.
$49.95 for the SURFACE Extended Combo also available at the Seidio Online Store.
I definitely recommend this extended battery. Seidio has always been there for me when it comes in terms of quality and reliability. NFC compatible battery is available for around $5 more. I've had their extended batteries on my Blackberry's and my Evo. So I'm sure this won't be the last! Tomorrow I am participating in a 12+ hour event, I am confident I won't have to worry about a charge during that time. I'm looking forward to showing off my new battery.

Not something I would get but I'm sure it's great to have that much juice Thank you for the review.

It was moderate usage throughout the day. At the amount of time it was on... the %'s show. It's not like I'm gonna sit on Facebook 20 out of 50 hours. Sure I can do a stress test, but those numbers mean nothing when you don't know how it equates to real usage.
I'll see what I can do.

Interesting
I bought a 3300 mAh battery myself.
With stock battery, i got 6-7 hours of screen time with wifi on and pretty low brightness.
With my new battery i got over 16 hours of screen time with wifi on and brightness at maximum.
This is the GT I9300 with stock everything.

Nice review. Any specific reason you went with the Seidio over the Mugen?
I had a Mugen on my HTC G2 and it was fantastic. I never found myself frantically looking for a power outlet.

It's just too thick for my liking, I can't use some accessories with it

way too thick and ugly for me

had the seidio extended on my evo 4g.... straight love is all i can say.... considering the nfc ext for my s3 now....never tried mugen....actually jus heard of it... cheers

I say Mugen belongs on Hondas. I've always been a fan of Seidio cases and tried out their battery and it worked well for me. So I stuck with Seidio and didn't change.

It will not fit a honeycomb case correctly at all. the "bump" is lesser in width and length.. it will look like butt. (FYI)

can we get a length and width dimension of the "bump"?
and is the "nonbump" the same size as stock?
I ask, because THIS may work with a DRACO!
(and if you decide to sell it, contact me, You are a great seller.)

Seidio also has other new cases out. I think they have an Active as well.

Mugen 2300mAh battery-is it worth it?

I'm thinking of getting the Mugen 2300 milliamp/hour battery, but for 44 dollars, is it worth it? I game a lot, download a bunch of apps or update them, facebook, browse Google Play, etc. Will I have any issues with my Speck Candyshell case? I'm thinking of this one because its size is the same as the OEM battery and I don't wanna have to get a new battery door.

been using the iphone past month just switched back to the s3 today. Well last night.
Battery fits oem door. On my first charge so i cant comment on battery life.
Theres a 7 percent discount code that u can get on the website, i forgot where. I bought it when it was on sale for 38.
Shipping takes about a week and a half. They ship from china!

for the price, i would say no
its better to get the oem samsung battery.
its cheaper i think
slighly smaller capacity
but at least its made by samsung and can be more trusted
just my $0.02

Bad resource. I'm using Mugen Power for 2 years already and cannot imagine an Android phone without their battery.
The 2300mAh is more of a replacement battery, because it only adds 200mAh, but if you really need power, I'd go for their 4600mAh battery.

Looks interesting. It doesn't seem like its false information but maybe they decided on making better quality for the S3 batteries. I'll be receiving the 4600mAH Mugen battery soon and I'll have bench mark comparisons against the Hyperion, Anker, QCell, and Seidio. Hopefully it turns out ok for the price Mugen's charging us.

For the price it's just better to get one of the extended batteries /w door off Amazon. They're cheap and juice filled.
I'm using the OEM, because I don't want a huge-mungo thickness out of my thin phone and the battery services me well enough.

maybe the information is too old..but he was using a hardware to test the battery performance..so i think the test is valid.
below is an example of batteryboss battery test result on xda..

I wouldn't spend that much. I bought two Qcell batteries and a charger on Amazon for $25. They advertise 2300mah. Not sure if it's truly 2300 but it last just as long if not a tiny bit longer than my stock battery. They also have NFC built in. Individually the Qcell batteries are $10, so you could have 3 spare batteries and a charger for less than the price of one mugen battery.
I've been using the Qcells for about 2 months now. I havnt had any issues with them and NFC works great.

They got caught putting a fake capacity. Switched the title to 2100mAH

I also use the QCell batteries and they work great. One of the best deals on batteries in my opinion. I have also tried other ones from eBay and they don't even come close to the QCell ones.

Looks interesting. It doesn't seem like its false information but maybe they decided on making better quality for the S3 batteries. I'll be receiving the 4600mAH Mugen battery soon and I'll have bench mark comparisons against the Hyperion, Anker, QCell, and Seidio. Hopefully it turns out ok for the price Mugen's charging us.[/QUOTE
I also just received a 4600 mugen for my s3 I can not find a case I tried a hyperion and it did not fit. Do you have a case on ur s3 with your mugen battery?
