OEM Battery

I'm looking for a spare battery and came up with this on ebay. It looks like it's OEM one with NFC function, but the price is too good to be true, cuz there are some seller priced it around $30, which makes more sense.
ebay.com/itm/New-Battery-for-EB-L1G6LLU-Samsung-Galaxy-S-III-S3-i9300-2100mAh-/140785352440?pt=PDA_Accessories&hash=item20c775fef8

Amazon has third party seller for the oem w nfc for 30 also.
Sent from my GT-I9300

I ordered this one:
http://www.ebay.com/itm/27100367050...NX:IT&_trksid=p3984.m1497.l2649#ht_827wt_1396
2 batteries plus an external charger for them for $18. It says OEM with NFC, but we'll see. I'm not sure how much I'll use the NFC feature anyway, but I'm hoping this is what it says it is.

It looks like the OEM but I dont see NFC anywhere.

Tempting due to the claim of OEM. Any bets on them being counterfit? Note the seller also offers a 2500mAh "compatible" version.

I emailed the guy. It has no NFC antennae, those are extra lol oh well I just need backup battery untill OEM price comes down.

So it's not really OEM then is it? Don't the OEM ones come with the NFC built in?

Sadly, how can it be an OEM battery for the SGS3 without the antenna?
Does anyone have the P/N off of an original US version of the battery? I'm still waiting for mine. I contacted Anker about when they will stock one and they asked for the P/N. I've had great success with the Anker batteries in my Touch Pro 2 (on Sprint) which is what I'm upgrading from.

How can you tell if a battery has the NFC? Aside from the markings on it.

I had ordered this: http://www.ebay.com/itm/16082851278...NX:IT&_trksid=p3984.m1439.l2649#ht_738wt_1396
New 2100mAh OEM EB-L1G6LLU Battery + Charger For Samsung Galaxy S3 III I9300
from : favorite444
Received it today. Looks like OEM, slightly different markings but says 2100mah and says Near Field Communications on it. It's charging up right now so I'll report back if NFC is actually working.

Grr, no NFC...what bs. Why the heck would it say NFC if there is no NFC. Will reach out to seller to get some kind of credit (not sending this **** back to china). I guess its OK as a replacement battery, but I have NFC tags that I'm using.

Emailed the guy and got a full refund! He even said not to return the battery.

Congrats! May I ask if you are using a US phone? I'd like to know if these batteries work in the US releases of the S3.

Yup, ATT phone. Battery worked, just not NFC.

Will all 9300 batteries and accessories work for the ATT variant? I was thinking they were different batteries for some reason.

Stock Samsung battery for $25 with NFC

Difference in performance between OEM 3.8v and third-party 3.7v?
I've seen several third-party batteries, but none are 3.8v. I was wondering if there is a notable difference in performance between the different voltages or not. Thanks

Spare battery and NFC?

Hey guys,
I bought the official Samsung battery with the NFC antenna and now my NFC won't work.
Do you have any idea how to get it to work again?
Is anyone else having similar problems?

are you sure its not a fake?

I bought two of the supposed real ones too. They had Samsung logos and even said NFC on them. Every part of the packaging was the same on the battery except the fake was made in Hong Kong the real in Korea. I M okay with the battery however, it is what it is as for $20 I got two backups and an external charger

it came with the cradle-charger so I don't think it would be fake.
I noticed that some galaxy nexus users were having difficulties with using the NFC function when swapping their batteries..
the only solution for them was to do a factory reset..
For those of you with an extra battery , could you check to see if both of your batteries work with NFC please?

Thats a fake battery, if you want I can get a whole lot of those batteries stickers from china.

So where did you buy it from? I have my hand around my crystal balls and I predict Ebay.

lol, did you buy from amazon directly or a seller on amazon? i have known sellers on amazon selling fake crap trying to pass them off as genuine. but put your original battery back in and check if nfc works to test i suppose. i don't see why changing the batt should stop nfc working as it only contains the antenna and not the nfc chip.

I put in my original battery and the NFC is working fine.
I then tried the new battery again and the NFC works too!

Verizon 2100mah extended battery include NFC?

I had to buy the extended battery for my GNex replacement since it was my 2nd upgrade phone due to issues and I'm wondering does the extended battery have an NFC chip in it or what? I'm going to be really pissed if it doesn't have it and need to buy one that does have an NFC chip in it. I bought it from Verizon in store.

It has NFC

Yes it has it....pretty sure the box mine came in said extended battery w/ NFC chip. Could have been wrong...but pretty sure the box says it right on front.
Sent from my Galaxy Nexus using xda premium

Box never mentioned NFC on it and the back was a PITA to get on so I don't want to take it off to check the battery to see if it said it. I swear, that back cover came with a few bent pins right out of the box and made for a really hard time getting it installed perfectly.

As mentioned, it does have it. If the extended battery cover is a pain, put the stock one back on. That's what im using with the extended battery.

They just sent me the phone itself, no battery or cover. Had to buy the extended battery and cover.

I think the nfc is in the phone, the battery has to have the antenna

NFC problems

I have a 3500mAh extended battery that I bought off Amazon. I forgot the brand name lol but I don't think it matters. Problem is that my NFC chip has stopped working with this battery. I tried using Google wallet at a vending machine that it always used to work, and now it just sits there and shows the wave graphic as it's loading, and never competes the connection.
I'm not sure if I damaged the antenna somehow or if it's possible that the antenna is now dead, because it used to work a couple of days ago and now, nothing. I haven't tried using android beam with another phone yet, or testing it with the stock battery as I'm not home (I'll try those later) but any thoughts are welcome.

does the battery say it has NFC? if not, it will never work
the antenna is in the batteries and without that, NFC will never work.

Funny, mine started doing that after the latest update. It took the .53 left on my google card ok, but I can't get it to charge any of my cards. And I thought it was just me but maybe not.

I'm pretty sure the battery has NFC. The amazon listing said it did, and it was actually working until a couple days ago (probably the latest update)

Just tested it with my girlfriends GSII, and I can easily send links, youtube videos, maps etc through NFC/Android beam both from my phone and to my phone. So my guess is it's Google Wallet.

Yet another battery topic...

Been reading some of the other topics here trying to learn which is the best choice for an extended battery for the T989. I've seen praise going out to Anker and EC Technologies, an extended battery for the Galaxy Nexus, someone having decent luck with a battery with Chinese printing on it, etc.
So let's make this simple...
1. Is there a definitive list of which batteries have consistently shown better performance over others and have shown to do at or above the expected return compared to the stock battery?
2. Are there any particular companies/brands/etc to avoid at all costs? As in, so bad that even manufacturers of other below-par extended batteries can honestly brag about not being THAT bad.
3. From what I've read and learned, most non stock batteries don't support NFC. Are there any reliable extended batteries that do? Are there alternatives to keep NFC available even if the battery doesn't support it? I have a feeling the answer is no to the last one, but I could be wrong.
Not really battery related, but charging related...
1. I've come across a dual purpose charger with the Sprint name on it (via ebay). It plugs into a car but you can unfold prongs on it so it can be plugged into the wall. On the end (away from car adapter), there are two USB ports (one open, the other you can uncover when needed). Are those any good? Main interest here is the dual USB option as well as being able to use in a car or in a house.
2. I guess more importantly would be, are the accessories seen on ebay generally reliable (Buy It Now auctions, reputable sellers of course)? A lot of the car plugs I've seen look like I wouldn't have much to grab to pull on when needing to unplug it and that worries me. Also concerned about the quality/safety/reliability of the products and thus the question. If they are all pretty much "all the same" just different looks and such, but otherwise all safe, then that's great.
3. From #1.. Are there any reliable/reputable car/wall chargers that provide more than two USB ports? Like the idea of it being a single car/wall charging unit, but if it's two pieces (with more than two USB ports each), that works too.
Ever since getting and starting to use the T989... Wow, I wonder what I'm doing to cause it to need to be charged 20 times/day. (Not literally.)
For the record, I had made the slight boo-boo of getting a pair of the cheapo 'extended' batteries before reading up on them. Not too bad though, doesn't hurt to have spares. I saw a reference to recalibrating a battery, but when going into recovery mode, didn't see an option referred to for resetting the stats. Are there any decent guides for proper care of a battery? Best practices when first getting it, when to charge it, not charge it, etc.
Thanks for any help provided. Now off to enjoy my phone some more. Haven't talked much on it yet but hey, only had it about three weeks.

for your answer for number 3 there is an app called super beam if my memory serves me right and has a blue kind of wifi signal and should serve as a good NFC "alternative"

By alternative, do you mean it's not NFC but serves the same purpose? I'll definitely check it out, as I can see the usefulness of NFC. Still would like to know if NFC itself can be accomplished when using a battery that doesn't support it. Actually, more of, wanting to understand it just enough to know if it's possible and how (if so) or why (if not). I hope that makes sense.
I had tried bump but that was a bit of a disappointment. Will try looking for 'super beam' and see if I can find it. Thanks.
Edit: Found it.
SuperBeam (com.majedev.superbeam), without a space in the name. Looks promising, will try it out.

Basically if its not a well known, reputable brand name (samsung) they have no reason to be truthful about mah
Most of the no brand batteries are equal or lower mah than stock.
If samsung could fit more mah in a battery of that size, why would they not?
For charger testing use this
http://forum.xda-developers.com/showthread.php?t=1801608
Higher numbers = faster charging
The max the phone will pull from a good charger is around 800ma, usb ports on pc's are limited to 500, which equals slow charging

Profits come to mind. Could be that they intended to sell an extended battery but in the end never did (did they?) or wanted to leave room for improvements as a selling point in the future. I'm sure you know companies will do that sort of thing to stay in business.
When I asked about ones to avoid, I meant if there are any particular ones that are the bottom of the barrel, even among 'generic' batteries. Perhaps identified by the label itself even if it doesn't have an actual name on it. Would still love to hear feedback in regards to the more popular batteries, as I don't want to order a pair from Anker and then come across a group praising some other brand (for example) and of course, vice versa.

So aside from the back not closing 100% (or can it with some effort?) it works in the S2?
Edit: Found answer in Galaxy nexus battery, apparently it does. Ordering one as I update this post (shipping is $6.50, not a bad deal for battery and cover).

I modified my battery, with a file. The result is a less buldging door

Oh and the cover is only for the Gnex, you have to use your stock t989 battery cover
In terms of 3rd party batteries, anker is supposed to be one of the better ones.
Search the forum for anker broke to get an idea if the "best" third party is any good

Yeah I figured as much, still not a bad deal. I could probably sell the back on eBay, so that someone else ends up with it. Might not matter too much with the bulging door, as I'm using one of those 'Heavy Duty Rugged' cases. The one I got on eBay is item # 620107891193. Not really into the idea of doing anything to a battery, for fear of causing it to leak or something else which causes problems.

Will do. Still need to check out that app you mentioned in the previous post.
When I first looked at the deal link you provided, the date alone had me thinking, "Oh yeah, this is likely long gone..." but decided that I had nothing to lose by checking it out. As you probably guessed by my last post, it's still good. Many thanks for that.
