Been using this Anker battery exclusively for over a week now. Getting 2 days of use easily, although a light use with screen brightness on auto, no watching movies either. Just basic email checking, web browsing, etc. Ran this over the weekend, no wifi, 4G only. I guess it doesn't matter since it's all relative comparison, and relative to stock Samsung battery this Anker 3100 mAh performs better.
[General Accessories] ymmp:
Few questions, thanks!

1) Does anyone have any experience with the Ankers in the AT&T GN2 (i317)?

2) Do they weigh exactly the same as the originals? (On that note, it would be interesting to see if the swollen Ankers weigh more than brand new ones. Perhaps that would help detemine if it is internal leakage or taking in some moisture somehow)

3) Does anyone have any experience with the supposed real original Samsung batteries being sold on Amazon for about the same price as the Ankers, or even cheaper? They are being sold by highly rated vendors and are getting mostly very positive reviews, with some saying they work poorly and a few claims that they are fakes without any proof for that assertion.
[General Accessories] vectron:
It should work the same on any carrier phone since I'm not aware of carrier specific oem batt. With weight, good point. Obviously I don't see any swelling, but can weight both for sure. Also, Amazon is very tricky. Anybody who buys on Amazon can create a merchant account within minutes and can sell "similar" item under original manufacturer listing tricking you into thinking you are buying genuine samsung oem battery. Be aware of who is the actual seller. There will be very few online stores selling actual oem part because those are more expensive and can't compete in listing with cheap fakes. That's why I trust only a few names like Anker, Hyperion, and Mugen.

Anker batteries expanding - Samsung s3. This was after 6 months in continued use. Bought these from amazon.com and now I'm in the Philippines, cannot process return!!

Hi İ have just registered to this forum to post my opinions on this battery. One of my friend brought me this 2 batteries with its wall charging equipment. At first they are ok but after 2 3 months. İ noticed that i couldnt close the cellphones case as easy as before. Then i lined all batteries side by side and noticed that i can spin them like crazy except the original one. Middle of the anker batteries are swollen really bad. İ am from turkey and my friend brought me this from US so it will be more expensive for me to refund.

İ also got photos taken from ipad but couldnt upload them from ipad. İwill try later from my comp.

Lastly i charged all my batteries (including the original samsung) on the wall charger that comes with anker batteries. Never overcharged them, cycled one by one (one on phone, one on charger, one full battery on the table, when my phones battery is %5-10 i took it off, insert to the wall charger, put in the full battery on my table to phone, and put the recentlycharged that i took from the wall to the table). İ have been using all 3 batteries exactly same time and same usage, original samsung is still flat and the 2 anker is bloated like hell that they cannot be charged through their original wall charger. İt falls off the charger :D or if it stays there it wont touch the charging point so no charging. İ think next time i will stick with the original samsung batteries.

I have written a pretty similar review for these a couple of pages ago, pictures included et all. It seems to me that these batteries have a genuine problem, as you are the 4rth or the 5th user to report this swelling on this thread itself. I just hope that people who are gonna buy these batteries and waste their time in replacing/returning these just read these reviews before they do so.

I am currently in the process of getting Anker to replace these. I had brought these batteries through an acquaintance and unfortunately he hasn't been able to provide me with the Amazon order number yet so I might have put 20 pounds down the drain by buying these. Even though I have provided Anker with the battery Serial numbers, product IDs and related numbers on the package along with photos they have till now been very unhelpful in this regard. But lets see what happens.

This is very interesting how all three problems have one thing in common about people using external charger for the battery and all three living outside of US. Do you need to use adapters/converters to power up the wall charger? I wonder if that could be a contributing factor. Just so weird...

I tried googling this problem, and there is hardly any mentioning of any anker swelling problems. I mean, the top google result of this problem is actually this thread. So I would not call this battery a waste of money because obviously thousands of anker batteries have been sold for different phones and if this would have been a wide spread problem - you will read a lot more complains. It's a nature of on-line forums, people come to share their problems rather than praise the product. I guess that's what I do with dozens of my reviews of different N2/S4/N7 accessories - praise the products :)

But either way, I'm glad you guys are communicating with Anker and providing to them all the details and pictures. I'm sure any company appreciates a feedback how to improve their products!
[General Accessories] SacGuru:
I think out of the six people who have reviewed this battery on this thread, four have had this swelling problem. Out of them, the first two were Americans, the second one even has a T-mobile s3 if you check his other posts.

I don't know and can't say about Anker batteries for other phones - I haven't used them - but the ones for the galaxy Note 2 seem to have a definite problem.

I used the external charger, as I am sure many of us must've done. What use is having an external charger provided by anker if you don't charge your batteries through it? I am sure Anker did not give the charger free with the batteries just so we can keep it boxed. Neither did they provide me with a warning stating 'do not use the external chargers we have made...the batteries may swell'.

Even if an external factor has contributed to these swellings, as you seem to suggest, then there is a very important question which is left unanswered - why didn't the original battery swell in a similar way? Doesn't this itself prove that there was a manufacturing defect with the Anker batteries?

Infact, yours is the only review here which actually praises the batteries. There is another guy who says the batteries work 'just fine', but he himself admits that he has been using the batteries for less than two months. My swelling had appeared only well after three months of usage, and 4-5 months after the batteries had been brought although as I was using the batteries sequentially the real time usage for each would be around a month.

As for google searches, they depend on the keywords used. I remember that earlier I found a forum entry somewhere which stated how an Anker battery had burst inside his Nexus phone while he slept. I probably used keywords like 'Anker battery swelling' or something like that, instead of searching for general reviews, which I am sure you must've done too had it been your batteries that had been swollen. That entry all in itself was what prompted me to find this thread looking for users having similar problems.

I am sorry for the rant, but this is one of the reasons why forums are here. Also, what would you suggest to a prospective user of Anker batteries for the Note 2 - would you ask him to buy batteries which have a probability, however small,of swelling up after an usage of around one-fourths of an year, or suggest to him that he should buy a genuine samsung, which though is a bit costlier, doesnt swell, and has a better chance of getting replaced with a warranty in all nations samsung products are sold.

Im sorry but I have own anker batteries for quite some time now, and have come to the conclusion that it is the owner who is doing simething wrong regardless of what the case may be it is on them and only 10% is manufacturer error.

I have own several anker batteries for the Samsung Epic 4G, Note 2, and Nexus S 4G. All of which operated just fine even in low temps im talking like 20*F. Highest temp I've seen is 118*F. And that's for short periods.

All batteries were 10% better from OEM. The user has to seriously try to break these as in extreme humidity, keeping the battery constantly hot. Ihave not had any swelling over 2 years of my Epic 4g or Nexus S 4g batteries.

As for the Note 2 I have owned the 3100 for 5 months and the 6200 which was discontinued had 2 of them which performed well no issues. Only reason why the 6200mAh version was discontinued was bad battery cover design.

And I can say that 90% of the time it is user error why something goes bad.

I wanted to buy an anker battery but now i should try zerolemon. I don't want a battery defected after 2 months
[General Accessories] SacGuru:
Also, I just contacted samsung India today. They directed me to the nearest Samsung dealer near my locality regarding my query for the cost of the genuine Samsung battery for the note 2.

The dealer told me that it comes for around Rs.1700, which is £20 or $30. I suggest you call Samsung USA to enquire about the battery. As far as I remember, I bought these two anker batteries for around £20 too. So the cost is exactly double one can say, though as the difference is a mere £10 I would suggest anybody reading to go for a genuine Samsung battery.

You can refer to my extensive Zerolemon battery review on this forum, it's the best battery if you are looking for extended capacity up to 9300mah!!! But if you want to use your original case with stock oem footprint battery, you have only two reliable sources. Either buy original Samsung battery for $50 but from Samsung direct only (99% of stuff on ebay and even amazon are fake) , or get Anker replacement battery which according to my extensive research has the best performance and reliability (don't take my word for it, Google swelling problem with every other brand name to see hundreds of complaints versus only single digits complaints found about Anker only on this forum). Plus I know that both Zerolemon and Anker offer a great extended warranty so you are covered for a long time if there is any defect down the road.
[General Accessories] vectron:
Good point, my friend! Thanks for follow up!
[General Accessories] ppn7:
Maybe the swelling are due to :

-bad manufactiring

-overcharge like +12h everyday

-overheating using in some country where the sun is hot!!

I think finally i will try one of these anker battery and I'll buy an external cheap charger on eBay. Zerolemon seem to be thinner than i thought
[General Accessories] tdamocles:
Swelling of the batteries look to be overheated by overcharging. Usually caused by charging a battery too fast. Sounds like the chargers are suspect.

Have you ever seen an agm optima car battery being charged over 4 amps.? In about an hour it starts whistling dixie and it starts to swell.

I have an Anker in my i317 since november and it hasn't swollen yet. It is only charged by the phone.
[General Accessories] ppn7:
So with a low power charge it will be Ok if i buy one which charge about 450mah on eBay store?
[General Accessories] XxLostSoulxX:
Your normal Samsung charger will be just fine. Just don't overcharge it meaning leaving it on the charger
[General Accessories] ppn7:
I really need an external charger because i would switch battery every morning and use my phone at night without charging
[General Accessories] SacGuru:
Have finally recieved a positive reply from Anker stating that they would be sending me new batteries (at the UK address). I just hope that the swelling doesn't show up in these ones. Maybe storing them in the refrigerator will help...

Anker sells a pack of 2x 3100mah with ax external wall charger, I think 600ma charging output. So I theory it should take 5-6hr with that one to charge the battery. But as it was stated above try not to leave it in for much longer than that.
[General Accessories] vectron:
A happy ending :D
[General Accessories] Raging_Ken:
I just got this battery for free from my friend who leaves in US, since he's changing to Galaxy S4. For all i know, it has better life than the original Samsung Battery, and i think he's been using this for around 5 months. I'm charging the battery now, and i'm gonna check if it's swollen or not. Gonna update here after that.
[General Accessories] billymaloney3:
do they do NFC? I'm assuming no?
[General Accessories] XxLostSoulxX:
They do, it's not in the battery it's on the battery cover. Since you're using your original battery cover you will have NFC support.

[General Accessories] gshadow325:
dude, lets think about this.

Question:

Owner doing something wrong? How? How can you do something wrong to a battery? You just plug it in and use it till it is dead and repeat process. Anker, Zerolemon, OEM or whatever. How can you use a battery wrong? It plugs in one way, it gets drained one way and recharged one way.

So it goes back to, How can you be doing something wrong? Dont see any of the OEM Samsung doing this.

I have been using Akers for 2 years now in serveral devices. No problems with those devices and batteries. I only have swelling in one battery, out of 8 Ankers.

So dont tell me i am doing something wrong.
[General Accessories] joshm.1219:
I mean it is technically better to keep a lithium ion battery around 50%. The real point is that you're not using the swelled battery any differently than any other battery you've used, but only one of them had swelled. If you were really "doing something wrong" that could actually swell the battery, wouldn't each one you own have swelled?
[General Accessories] XxLostSoulxX:
You can do something wrong as an over charging the battery for long periods of time also not charging it for a long time as well as bring it to their percent all the time there are ways to do something wrong to the battery
[General Accessories] gshadow325:
that is stupid. explain to me why the stock battery doesnt explode then?

so out of the millions of note 2 sold only the 6 people that responded to this thread is doing it wrong. we are plugging our device before bed regardless of percentage left on the phone and unplugging it when we wake up, we are over charging it. these 6 people including me, we are the only ones in the world that does this.

i am sure when the battery gets manufactured, it takes months before it even reaches a consumer. so we already messed it up before we even got the battery by not charging for extended amount of time

Bias Review!

Anker's been contacting members here on XDA and giving batteries away for Free and then asking for favorable reviews.

I know...I was one of them.
[General Accessories] vectron:
Really?!?. Anker includes a note in all of their products with a link to join their VIP program to review their products. It's not a secret. I have reviewed close to a hundred of different accessories and gadgets in XDA-Dev and AndroidForums in the last 5-6 months, check out my list in the signature. Every single product in there was sent to me by Marketing departments of those companies, including Anker, asking me to review and to provide a fair unbiased feedback which I have. Furthermore, every review I posted, including close to a dozen of products from Anker - received hundreds/thousands of views and a TON of replies from other XDA forum members with their opinion about the product. In addition, you can also view Amazon reviews (some of which are from VIP program members as well) and rating from other users.

So what is so biased about my review or any other of the hundred reviews I posted and shared with members of this community? If your statement is based solely on the fact that I received this product for review rather than paid for it, and you have used this battery and don't agree with my write up - I would be more then happy to hear your opinion about it, cisco-stud.
[General Accessories] ppn7:
I got my anker battery yesterday but didn't try yet. I'm waiting for my external ebay charger. I hope that will work for a long time even if i bought it only for 4 $...

Hope it will nlt destroy my battery too
[General Accessories] vectron:
With ebay charger you have nothing to worry about since all those budget models can charge at only 350 mA. So it will take you 9hr to charge your standard battery from empty ;) Slow charging should never hurt. Other chargers, including the one Anker offers in their 2xbatt + charger package has 600 mA charging speed, so that one will be faster.
[General Accessories] SacGuru:
I have finally recieved replacement batteries from anker for the swollen ones for my note 2. They came with good packaging as usual, and they have included a charger as well, which is an unexpected gift!

I sure hope these remain as thin as they are right now and don't go the way my earlier ones did. Will follow up with more as I use them for a couple of months.

Glad to hear it!! Good luck with these batteries, an I too hope you don't have any issues this time around! I'm a fan of Anker from my OG Evo and Evo 3D days, and have always had great experiences with their batteries. Hate to hear that people are having issues and Anker might possibly be dropping in their quality! Please keep us posted!

[General Accessories] steve austin:
kinda bummed out that Anker is not making a 3500-3700 mA battery for the note 2 that fit inside the original back cover. I hate extended batteries because thy make any phone look bigger. this is beyond the case with the note 2.

I had an HTC sensation. I was a little leery at first when I saw the beefed up specs on their battery but it gave me an hour or two extra life and it fit snug - even though it had more juice. I see some other brands advertising more mA's, but i have not see one rally good review.
[General Accessories] vectron:
How come you didn't contact them for replacement? You get 18 months warranty, use it! Even if you didn't save your receipt, I'm sure with proper pictures to support the claim they will send you a replacement.
[General Accessories] vectron:
Unlike HTC and Motorola, Samsung always max out their standard battery capacity to get the best spec. There is a physical limitation how many cells you could fit into a specific footprint. For our N2 it's 3100mah as max capacity. You can't squeeze in any more.

As I mentioned before, Anker doesn't make their own batteries, neither does Hyperion, Onite, or any other sub-$20 manufacturers. Only Mugen makes their own stuff, that's why it's so expensive. Instead, Anker researches and tests other sell batteries they sell under their own name. But everything gets tested and verified to meet every standard before they sell it and offer full 18 months warranty with it.
[General Accessories] joshm.1219:
While I believe 3100mah is the maximum capacity we can get for the note 2, Samsung does not always max out their standard battery capacity.

When they released the Galaxy Nexus, Sammy came out a couple months later with a battery that had more capacity that fit in the original back cover.

Now with the S4, Zero Lemon has come out with a 3000mah that also fits in the original back cover. I believe the standard is 2600mah right?

My two anker batteries for note 2 is swelling too. Have contacted them with pictures and they are sending replacements

I also have 3 anker battery for galaxy s3 that have swollen. Unfortunately I toss them already. Forgot about the warranty.

[General Accessories] joshm.1219:
It's been through a week of cycles, me changing between each battery. Of course, it's difficult to replicate the same usage but I posted this more to show they basically have the same usage, I had actually convinced myself in this last week that the anker performed better but this just goes to show it's all a placebo effectn at least in my case.
[General Accessories] vectron:
Fair enough! Good feedback for those who are trying to buy a stock replacement. For US buyers, we have a choice of $11.99 Anker or $50 (or maybe $25 with that 50% registration discount) Samsung original, versus people overseas might only have a choice of Samsung.

BUT please, do not be fooled by ebay or even Amazon sellers offering "Samsung 3100 mAh" for $7-$8, those are fake!
[General Accessories] joshm.1219:
Ah yes that was point I was going to make! Lol I can't believe I was going to say that when I started typing that post and never did. :p

I'm very glad I only spent $12 versus $50.
[General Accessories] gshadow325:
Anker has no obligation to contact you and then give away free batteries. thats against every capalistic rule! go out of their way to give you free product at their own dime? thats a loosing proposition, then they only ask you to rate their product? rate it never did they say you have to give a good review. Not many companies do that anymore. When i got my HD2 3 years ago, i researched what battery to get, got a anker. When i got my HTC Sensation, researched what battery to get..got a anker. This time in my Note2 didnt research nothing, got a anker. This was the only time i ever had trouble. What did they do? Ask for serial number and they send me a free replacement! Only other company i can say that has this type of customer service is Otterbox and i have 6 different kinds of cases for various devices from otterbox @ $30-70 each!

Thank you for that. I have bought several items and passed on a few because of your reviews :good: thank you again

from your reviews i am learing there are a a ton of fakes out there. I ended up buying a "charger dock" from samsung website thinking it was a docking cradle but it was a charger with a extra battery for the $25. Well worth it since buying the fakes usually mean just throwing the money out the window.

like [MENTION=3996566]vectron[/MENTION] , i am encouraging everyone to contact anker if you battery has swollen. i bought mine from ebay. contacted them on july 4th US holiday, got a response back by monday morning(expected delay but that was next business day). within 24 hours of me confirming the info they requested i got a email notification my replacement product has shipped. Never once did they say you have to give me biased feedback because i gave you a free battery. I am doing this willingly. :)
