are these 3800mah batteries real? - Samsung Galaxy Nexus

hi, anyone knows if this is real?
http://www.ebay.com/itm/3800mAh-Ext...Accessories&hash=item5d31f6c169#ht_5055wt_952
or
http://www.ebay.com/itm/3800mAh-Sam...Accessories&hash=item3a6f09ec2b#ht_2405wt_952

There have been tests trying these in a few older posts, no, these aren't actually 3,800 mah, in most cases, unverified extended batteries perform worse than the original ones. Save up and go for an official Samsung extended battery.

The QC on china batteries is very low. Some have even been known to melt and destroy the phone. I would not recommend. It is best to use a OEM or trusted brand

As far as I am concerned, if they can't get the name right (galaxy prime 3?!?) I wouldn't trust throwing it in the phone. Diddo on the qc for Chinese batteries as well...always rated way higher than u get

[Q] Best aftermarket BATTERY?

There is a company called Anker that makes high quality - high capacity aftermarket batteries for phones, however, I don't think they have one for ours yet.
I'm a little gun shy to buy aftermarket batteries again...
My experience with Anker Batteries:
I had one for my MT4GS and although it did last much longer, I kid you not it does something really weird to the phone. Call me crazy, but I had random people confirm this with their very own eyes. If you've experienced this too, you know exactly what I'm talking about.
1. Like I said, I kid you not, when I put in the higher capacity battery, it made the screens color look more washed out and blurry. Crazy, crazy I know, but it's darn true. Has anyone else experienced this?
2. For whatever reason, the phone would freeze often as well, whereas before with the OEM battery, everything was fine. I had to pull the battery almost 2 times a day to restart it from a freeze.
Interesting....
I was looking for an extended battery for this phone as well but when I searched for the Anker brand as I have it for another device, they all said not compatible with the AT&T or T-Mobile version.
http://www.amazon.com/s/ref=nb_sb_s...msung+galaxy+s2&x=0&y=0&sprefix=anker+samsung
The batteries for the international version are a different size than ours so no, they won't work.
also the other batteries might not come with the NFC
if you don't mind losing the NFC feature on the phone, then you can use the 2000 mAh original batteries from samsung

personally i prefer this over having it at the back cover like on the Nexus S
this means i can chance the phone skin any time i want without worrying about losing NFC
i saw many nice back covers for the Nexus S but couldn't change it as they do not include the NFC antennae on the aftermarket back covers for the Nexus S

No way! you 100% sure about this? I was planning to buy an extra battery but now I'm hesitate to buy. How do I know which battery has NFC and which battery don't? I thought on the galaxy S2 they integrated onto the phone.
just wait for a new version of the 2000 mAh with NFC
the last one i saw on the samsung website did not have NFC build in

Would the 150 mAH additional warrant the large price? (probably $50+)
Tmobile Galaxy S2 has the same battery as what...?
I'm looking to get a spare battery and external charger for my S2. Looking for anker or chichitec, what other device has the same compatibility as ours. Which ones will fit?
You may have a hard time finding cheap batteries for this phone because the NFC antenna is built into the battery. If you do find one, there's a chance your NFC will suffer because of it. If you don't use NFC, that may not be a problem. I on the other hand, use it daily.
The Samsung Infuse has the same battery.

Extra set of quality batteries?
Has anybody here bought a quality battery from ebay? there are batteries ranging from 10 dollars to 40 dollars and I'm just wondering if any of them are good? i don't want such an expensive extra battery but i also don't want a cheap battery that will mess up my phone.. speaking of which, can a bad battery mess up a phone's internal system? Thanks for the responses.
if possible, provide a link to the ebay listing or just tell me what i should specifically search for.
i'll suggest buying the real Samsung batteries if you can afford $40

thanks allgamer for the response. the thing is i can't afford the $40. should i just wait till a quality replacement battery comes to market? i used to have an htc pro and i bought cheap batteries on ebay for it that came in handy and worked well but my phone eventually died out (screen does not turn on all the time but it might be a wiring problem and not a battery problem). i was hoping there was a similar economically viable option for the galaxy s 2.
it might take a bit
because these news batteries comes with the NFC
so the cheap ones in ebay or where ever they don't usually include the NFC
I doubt it. And the Infuse has a lower mAh

i don't really need NFC with the extra set of batteries. NFC's potential hasn't been fully realized yet and i don't have much use of it as of now.
one question though.. if i buy those cheap batteries on ebay, will it destroy my phone because of incompatibility issues?

GSM Galaxy Nexus Extended Battery

Well I've been looking around for an extended battery for a few weeks and I can't seem to find one for it. I don't want the 1750mAh battery. I want a 3800mAh extended battery WITH NFC. Anyone know where I can get one?

NFC capable batteries are usually only made by OEMs. Currently Samsung only offers a 200mAh extended battery and I doubt they will be offering another.

NFC is NOT proprietary. It is a technology used by many manufactures like Samsung, Nokia, RIM, etc.. However, aftermarket NFC enabled batteries are uncommon. Most of the time they are only available through OEMs.
So all in all...there's no battery?
nope. your only choice is the 2000 mah extended battery

Look for the Seidio Extended Battery 3500mAH with NFC for the GSM Galaxy Nexus on their website (seidio online in google).
It's a bit pricey ($69.95) but WELL worth it imo...this battery + one of Franco's kernels makes my Galaxy Nexus have INCREDIBLE battery life (4+ screen time easily per day even with gaming and a lot of browsing on 3G) and NFC works with it too, I tried it personally at McDonalds with Google Wallet and it worked fine.
What would it take to put the nfc antenna on yourself? As in pull it off the stock battery and put it on the aftermarket? Or better yet on the inside of the backplate.
Is that tweezers and soldering gun work or would you need factory equipment?

It's definitely noticeable. My first day with it gave me 3 hours of screen on time and 14 hours of discharging time, only putting me down to around 30%.

I've tried aftermarket batteries of that small of difference, I personally believe samsung makes their stock batteries of higher quality than the 10$ dollar ankers or the likes therof. Therefore, I think its a wash as far as daily phone hours of usage. But I'm pretty confident the cheap aftermarkets won't last as long in the long run. I think the best option is just get a replacement battery, have it charging all day, use your phone to your hearts content, no extra bulk. Then at around 7 or 8 when its getting low if you had a big usage day, pop out the battery, put in the new one. We should be grateful as g3 users that we have this option eh.

Even if Anker claims 2200, it's true rating is under 2050. Stick to stock.
Polarcell 2400mAh
great quality. costs 13€ in germany, should be around 15$ - but im not sure if its availabe in the us
does not have nfc, but according to some posts in a german forum, there will be a polarcell battery with nfc in the near future.

How about you start by telling us where you go these batteries? As for NFC, it stands for Near Field Communications. It can be used in a way to pay for items, or bumping phones together to share information, such as pictures, contacts, etc. I am not a fan of it, I always have it turned off in my phone settings.

It does say on the sticker under the battery 2100mah so just wondering if running a 3200mah would be detrimental? or is it one of those things manufacturers do and have very large tolerances just to be on the safe side so as not have flaming s3 videos on youtube.
don't these cheap batteries pose a risk of leaking in the phone or something? Like what if the damage the phone!?

What, where did you hear that? The only thing I have seen people have to worry about with cheap batteries is how much of a charge they hold and how well they actually work. I have seen batteries malfunction due to ****ty car chargers before though but never just a battery fail while in a phone minus ghost stories from trolls on the internet.

mAh has nothing to do with the amount of current or voltage so I don't know what you mean by manufacturers having large tolerances?? And it wouldn't be detrimental, it would add to your battery life. (as long as the mAh claims are accurate)

these are surely too good to be true? 3200mah in a standard size?
yeah no need for a new back cover
Can anybody say something about how long does the phone works with this battery?
definitely need to get me one of these.
too good to be true
hey i just made some fast research on the seller of the item
i cant link the url apparently because i jus made the account but go ahead and check the ebay sellers' (utigertech) feedback. They are not good.
in short, this battery is fake and some user feedback states that it does not last even longer than the stock 2100mah samsung oem battery
so dont be fooled. If its too good to be true then its probably too good to be true

Testing of MPJ 3200mah Battery for S3
I have purchased one of the MPJ 3200 mah batteries for the Galaxy S3. I have bench tested the battery over 7 days with multiple charges and discharges.
The results are that the battery is approximately 2000 mah it does not even come close to 3200 mah. The sellor is being misleading on the mah and you are better off buying a standard battery as it has 2100 mah and NFC.
I will try and test a few more batteries in the next couple of weeks..

[Q] Best Stock Battery Replacement?

It fits :highfive:
How has the performance been? Reason I ask is many of the cheaper "replacement" batteries usually crap out either in a month of so, or stop charging to 100% all together. Also, why the heck is it so hard to find a OEM Samsung battery (EB-L1F2HVU in US or HVK in Korea) for this phone. I can easily find the shorter battery for the Verizon phone (SCH-I515), but almost nothing (unless you want to pay over $60) for the GT-I9250M phone.
Unless you can read Korean and order the OEM larger 2000 mAh battery (EB-L1F2KVK) directly the majority of us are out of luck.
Where's a good place to buy original Samsung one for cheap?
I found an 2450 mah battery which claimed to fit with the stock battery cover. But I read that its actually worse than stock battery and if you remove the seal around the battery it actually shows a lower mah.. That were reviews for the s2 version but I think it applies to that one too . Ive seen several 2300 mah batterys that claimed the same but assumed it was the same story..
