Samsung 2000mAh VS. Anker 1900mA

So I was thinking of buying an extended battery,
since i can barely last a day with the original one.
So what are thoughts?
Samsung 2000mAh OR Anker 1900mAh?
Or maybe another battery?*
Thank you
*Please no 100,000mAh chinese batteries..

It is more expensive than Anker battery but it gives more juice (20-25% more than stock) and many people say that the phone feels better in hand with some extra weight and thickness.

I also say go for the 2000mah by Samsung. There's a significant improvement in battery life. The larger battery also doesn't get as hot. and the phone's back is now flat.

Seriously, don't fall for that super mega over xxxmAh class A or whatever made from wherever. I'm having a great experience with the Samsung one, gives me additional 3 hours (at least) with heavy usage. I'm quoting one website that describes it "the S2 that should have been" which is true enough, at least from my experience.
I promise you, you won't regret adding some more off your pocket to get one... heck I even ordered it online and shipped it from abroad!

I am ordering it from abroad as well..
Know of any website that sells it for cheap?
Best I found is 40$+- with shipping*.
Thank you all
*Shipment to Israel.
P.S
Is there any case that supports the.new ''fat'' cover?

Was it from an online shop or real one,because here in Bulgaria its 35 euro at least?

Most Romanian online shops have it at less than 20 euros, with a back cover included.

I got a pack of 2 ankers and a charger for 12 quid. Amazing.
Spent 3 days getting drunk on a scottish beach and still had battery , you can charge a battery and the phone at the same time and the batteries are small so carrying a spare is no big deal in my opinion. That way you're looking at 2 additional days charge.

Here is a link to ebay to a extended battery for galaxy s2.
Its 3500mAh and also comes with the battery cover.

I've had good luck with Anker batteries. No, I don't work for Anker or anything like that at all, just a satisfied customer. They make good quality batteries. I don't have any experience with Samsung batteries, so I can't comment on them.

Charge time for me is 1.5 - 2 hours.

They seem to last less or about the same as stock 1750 mah one . Buy 2000 mah OEM one it has NFC and it will give u extra couple hours .

All these higher capacity rated batteries are a joke, these companies that sell these batteries can't fit more capacity into the same sized battery, its just not possible.

Same seller but it includes a battery cover

I have purchased 3 of the 2000 mah XPower batteries! They work perfectly fine!! It gives me more life than the stock 1750 mah!
Also its the exact same size as that of the stock battery... So no worries abt an extra back door!
And I got 3 of them + the wall charger for the battery for less than $10 on ebay!!
So now i have totally 4 batteries - 3x2000 + 1x1750 = 7750 mah!!
Definitely worth it rather than holding a clunky phone with an extended 3000+ mah batteries!!

Do you happen to have a link to the eBay listing you bought it from? I can only find 2 batteries + charger for $10 shipped.

Thanks, I did see that one, although it comes out to $13 including shipping. I was hoping to find a $10 one that included shipping but I think that may be asking for too much So I'll probably just go for the 2 pack + charger for $10 shipped. That will give me 3 batteries total, which should be plenty of juice.
Anyways, I appreciate you taking the time to look. Thanks!

I'm not sure either, sacthegreat was the only person to respond and he/she said that these batteries did have more capacity. I think it would be very difficult to measure this anyway, since there isn't a direct measurement for mah in the phone. And because the difference in capacity is relatively small (~14%) I'm not sure how easy it is to notice in daily use; changes in how the phone is used could mask the capacity difference.
So I've made up my mind, I think that I'm going to try two different brands of batteries (+charger) and see if one is better than the other

The total comes out to $10 shipped, which is the same price as buying the two pack with charger. So hopefully this will increase the odds of getting at least one good battery

I totally missed the shipping in the link I gave, sorry as I had no intention of buying it and didnt realize shipping wasnt included. I would just get the 2 batteries as I dont think the extra 3rd battery is worth like 30% more but if you need a lot of battery, I guess you can go for it. I dont have any experience with this battery but do with Hyperions and those have worked great for me. I just keep the phone charged and make sure the spare is charged as well. If I did get a bundle with 3 batteries, I think it would be difficult to keep track of all of them and remember which one is charged and which isnt. I like the simplicity of one spare battery and the oem one

It's the stock size itself! And i got a little battery life than the stock battery on my phone! Not a big difference, but i could notice it!

I just labeled my extra 4 batteries with a marker, so that i can keep track!
But my phone gives such amazing battery backup (both oem + spare)! And even charging is super fast!
I put my dead battery to charge and after 15 min, when i switched it on, it showed 84%!!!! And it discharges also very slowly!

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.

yeah i wish to know as well, seen these tonight on ebay and i will buy them but just wanted to see if anyone else has first. was gonna get the £6.99 single one first as a test. 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..

T989 Slim extended battery?

I'm at work and I got a customer that just asked me about extended batteries. I told her they're usually fat batteries that come with special battery doors.. but usually at least give 25-50% more battery life. Then she asked if there were any slim extended batteries. I didn't know how to answer her and all my gsearches came up with 3000MaH plus big boys. All I found was he Mugen Power 2000MaH slim battery. You guys know of any other options out there?

I am currently using an Anker battery that I bought off Amazon. It has slightly extended battery life at 2200 mAh. It is the same size as the OEM battery so no custom back case or chunkyness sticking out the back. Anker sells the single batteries or they sell a double pack with an external battery charger on Amazon, quite useful. I believe their products are on sale right now.

Anker 2200 mAh works perfect for me. I've been using 2 I ordered from Amazon for about 4 months. I get about 10 hours heavy usage time. I get well over a day on when I take it easy. Juice defender is an excellent addition to any cell as well. I would advise you to be careful when taking the battery out of the charger so you don't break the plastic that separates the cells. It can cause problems charging through the cell phone. Either way it's a great buy and I highly recommend.

You can charge them either way. Personally I use the external and the phone. I was just saying be a bit careful when you take your battery off the external charger. I have one battery that I can only charge through the external since I broke the small plastic separator... not a big deal though. It still works properly.

Yes, most aftermarket batteries (like the one WangLung linked to), if not all, don't have NFC support as the chip is located in the battery. The same goes for the ATT i777, but not the international i9100.
You can tell on many of these by the 4 contacts- one is for the NFC. This is why a i9100 battery (with only 3 contact heads) will work with a i777 phone (that has 4 contact prongs) - the connector for the NFC would just be touching plastic.
Don't know about the overcharging protection though.

I have the Anker 2200 MAh slim extended battery in my phone and it works great! I usually get an extra hour of on-screen time than I would with the stock battery.

Well worth the investment for 2 battery's + charger for around $25!

The one for $20 includes two batteries and a charger, while the $12 one only a single battery. For what you get with the $20 one, it never hurts to have more than one battery, especially if you're away from the charger for a whole day and you're using your phone often.
I do not own the Anker extended battery myself, as I am doing fine with the stock battery and I like having NFC ready if needed. But it does seem like a great battery, especially for the price.

Get the original OEM battery?

I bought the phone from my friend who didn't have the stock battery, and the one he gave me is terrible. Where can I buy the stock battery?

eBay sells them for around 6 USD. Alternatively, you can spend 10-11$ on eBay as well and get a anker 2200 mAh battery, which has slighty more capacity than the stock battery. =)

dont think the one you get for 6$ would be original however anker make good batteries and is worth the 10$ investment, you could also look at an extended battery from hyperion or anker in tune of 4200~4400mah

Ah true they seem to be around 12$ for the OEM, not sure where I got 6 from haha. But yeah anker or hyperion is the way to go for 10$ batteries that have solid performance, otherwise if you want an extra 100 mAh you can go for the mugen 2300 for 40$.

I've been seeing the 2100 OEM batteries around $15. The ones that are less are Chinese counterfeits. Don't be dumb.

Honestly, if you want the NFC capability, buying from the official Samsung website is the way to go.
However, if NFC isn't necessary, Anker makes great batteries. I got 2 for a good deal. Been using all 3 and have good battery life.
You can get them off Amazon.

dont think the one you get for 6$ would be original however anker make good batteries and is worth the 10$ investment, you could also look at an extended battery from hyperion or anker in tune of 4200~4400mah

I have Anker 2200mAh battery and i can highly recommend it. I also have a cheap 4500mAh battery, which has lasted even 3 days in normal usage. With Anker/Hyperion 4200-4400mAh, you can probably get even 4-5 days, because they are much better quality.
