best slim extended battery?

So im in the market for a new battery. A higher capacity one but slimline. I do not want a different size battery door. Anybody know of any good ones for a decent price?

Great question. I'm wondering the same thing.

I bought this one. I had to wait a month for it since is came from Hong Kong. I can get ~16 hours running the screen at 80% brightness, texting alot, 3g radio always on, constantly checking email. No complaints other than the time it took to ship.

I was sceptical but the reviews swayed me and I tried these- http://www.amazon.com/gp/product/B003XOUM12
I'm pleasantly surprised, I notice a definite difference in battery life and the wall charger is a bonus. For the price it's hard to beat and delivery was within a week.

$24??? Ouch man. I've bought tons of them and I always get them for $17 for two of them and a charger with free shipping. It usually only takes 2 weeks to get here.

Personally I have found these batteries no better than the stock htc red. With juice defender I get fair batt life with either...10-16 hours or so. I do find the wall charger useful as the battery never gets fully charged when charging in the phone.

There are no slim batteries that are better than stock, the only thing to increase your battery is to add a few millimeters oh my god, to your phone and get a 3500 you won't be disappointed, and yes like someone already said, use the search button next time this must be my like 6th time answering this question muskeg let alone if someone else did too, which I feel has happened too

the battery i have is a 2000mAh i checked it over. seems fine to me.

i get 17-22 hours with my best buy platnium battery (seido knock off) tht i bought off ebay.. so i would disagree there are some extended battery tht does work and there are some that doesnt have the right mah...

I have the 2000mah battery and its marginally better than my OEM battery.

The Seidio stock size extended battery sucks. Doesn't even charge past 90% anymore, and I didn't really notice a difference.

The Best Buy battery isn't a Seidio knock-off - it IS a Seidio battery that they package for Best Buy.

Where to get 1800mAh OEM Batteries that FIT!

Credit goes to Rakeshchn for asking if this would even work, and for the link to the first battery for sale
Okay guys, there's a thread here about how the Galaxy S II Epic 4G Touch battery might fit the Vibrant with no need for a new back cover. The rumor is true. I have two of these batteries, and have verified that mine are legit, and they fit perfectly. My phone actually has never lasted so long on a single charge since I switched to CM7.1, and I won't be going back to any battery of less capacity for as long as I own my Vibrant!
Here is the official page for the battery from Samsung
Here is the website I purchased from.
NOTE: I have removed the note about my batteries being fakes because after some research I have determined that Samsung actually has no idea what a serial number is, and is actually putting batch numbers on their batteries, so having the same number isn't a bad sign.
Here is the official page for the Extra Battery plus Charger from Samsung
Here is a website that seems to have the battery charger combo in stock and is selling it for $10 cheaper than Samsung MSRP. I DON'T vouch for them yet, because I haven't purchased from them ever.
Enjoy!

Dam, I wish it wasn't backordered on that website you ordered from. Im not gonna be ordering the one with the charger well since I don't need a charger and I'd rather spend that money on other things as I have wasted soo much on this phone already. I wonder when are thy gonna have more of just the battery in stock. A little better battery life on my galaxy s 4g would be great.

There's a few sellers on Amazon with them in stock, but they're a few dollars more than mobilecity. If you're in a rush for one, you could try there. Just search Epic 4g Touch Battery.

Good rule of thumb, Shaolin. If it seems to good to be true, it probably is.
Also, that battery won't fit in our phones. It's for the other models of the Galaxy S, not the Epic 4G Touch.

Check out this one. Not sure if anyone has tried it before.
But I have just ordered the 1800mah one

I received my 1800 battery a few days ago from mobile city, where OP vouched for. I'm getting significantly more run time with it. I'm a heavy user and the difference is very noticeable.

I only saw the 2430mAh one, and this sounds a little too good to be true. I guess if it at least gets 1900mAh it could be worth it. I am getting close to 24hrs from the Epic Touch battery now, though, and I have 2 of them, and a wall charger, so I am never worried about running out of juice anymore.
Sent from my rough sketch of a Vibrant on a brick.

I noticed that my two 1800mAh batteries have the same serial number, so if anyone else purchased from mobilecityonline.com and cares to check, mine are both TH1B907FS/5-B
Sorry to anyone who bought these on my recommendation for leading you astray with this. I emailed mobilecityonline.com, and will let you know what I hear back if anything. And have updated OP.

Fake or no fake. I am getting way better battery life from mine. Ill take fakes like this all day long!

I heard back from mobilecityonline.com and they said to call Samsung about the sn, but they only sold genuine OEM batteries. I still haven't had a chance to dig deeper, but I agree, the better life is worth the $20 all day long even if it is a fake.

Are you using Norton Utilities to determine battery capacity? It doesn't matter how big or small your battery is, Norton will always say 1500.

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.

Does the anker have nfc?

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.

[Q] Mugen Power 4600mAh battery for S3? Review?

I found this thread where G1_enthusiast reviewed Anker and Seidio batteries for S3, but I also found the 4600mAh battery from Mugen Power earlier than these, and ordered it.
All I head is that cheap batteries are made out of almost expired materials and work for like 200 charge cycles, which explains their price. The expensive ones like Mugen or Seidio work for 400-500 charges, which is better, but would be awesome if some one could review the 4600mAh one. I will post my results later when I receive it, but I don't have experience in doing such tests.

reason why they are not popular is the price tag, i used to think their company is out of japan but in fact they are base out of hong kong (people tend to think china stufff are ****ty). so what make their battery better than anker or hyperion? having say that, i have own their battery before (G2 and SGS2) and they do make battery longer than stock. however i was not into crazy testing at the time. i will not pay 100 bucks for battery again, as long as anker is in bussiness.
seido is the only battery company that is base in texas...thats not to say their factory isnt in china either. they also make quality battery in the past

Well, as I head many times and experienced myself on older phones (I have a 3900mAh from Mugen for Nexus S that works for 1.5 years already) - industry standards cannot produce a good quality battery and sell it for 10$. Those batteries are usually made out of expired materials. The issue here is not just the capacity but the battery life cycle. Cheap batteries have confirmed to last for 100-200 charges, however batteries from Seidio or Mugen last for 400-600 charges, not to say about warranty and safety + NFC support.
Also, for me personally customer support and brand presence is more important than being cheap. If I can afford a phone that costs 800$, I surely can get a good quality battery for a 100$. I will get the battery soon, btw, and will let you know.
I also posted this here: http://forum.xda-developers.com/showpost.php?p=30770441&postcount=85

I wonder if the Mugen battery will work with the extended cases that are being offered. I got one from Hyperion that I like. Judging by pictures it looks like the Mugen extended door may be a little bigger or designed different.
If the Mugen would fit with the other extended doors and TPU cases I would buy it. I've had great luck with them,

If a cheap extended battery lasts for 200 charges and I charge it every 2 days, it's still going to last over a year. I expect to have a new phone by this time next year if not sooner. So what's the big deal?

That is why you go for tested name brand but not super expensive. a mugen costs more than 5 times what a hyperion, qcell, etc. costs. but it is very unlikely they will last 5 times as many charges. there is nothing like a fresh battery!

Well, they're always out of stock...I guess they never back back-logs. Anyways, I've received my S3 battery and now I need to calibrate the phone according to their instruction. They say that it's necessary to charge 4-5 times for 8-12 hours before the phone recognizes the new capacity. Does anyone know why?

Why didn't you buy a stand with extra battery that recharges both at the same time and just carry the extra one with you? I did, 18 pounds in amazon.uk. That way there is no extra bulk, and it's much cheaper!

It looks like a knock off of the Hyperion setup. I would venture to guess the battery is over-rated. Side note, the NFC, while looks legit, doesn't work.

Just ordered it. Will let you guys know how it turns out once I get it (probably in 2wks).

I have one I ordered from eBay that looks identical and doesn't even last as long as my stock battery. Better off getting a brand name when it comes to batteries in my experience.

Thanks but this hyperion seems to be only sold in the USA. Cant get it here in the EU

Funny that after placing an order and reading negative comments about this cheap battery, I got a reply they are out of stock and just refunded my money. At the end it worked out to my advantage
But in general it's kind of sucks because I have a collection of so many "standard" cases, and can't use them with extended battery. I wish there would be an extended battery, perhaps 4000 mAh or 4200 mAh that has the same or close physical dimensions and would fit with OEM battery cover and standard case. Anybody has any suggestions?
