Awaiting for their response on whether or not the power pack to connect via USB or POGO. I'll provide updates once I receive their response.

That's awesome news

Awesome news indeed. When I first heard they were either doing the internal battery and battery pack, I was hoping that they'd go the battery pack route. If possible, I'd prefer not to open up the One X since I'm rather clumsy.
I'm just hoping that the Mugen design of the battery pack will look nice.

Hopefully it's pogo pins and slim. And doesn't cost a fortune

Got reponse.
The customer rep says that the product is still in the development phase, therefore no battery capacity and how the battery will be charged is available yet.
Since the rep told me the approximate release date may be mid-July. I'd say it's fair to check back with them beginning of July.

Also sent them a message on FB and they confirmed it's a battery pack using the pogo pins (gave them a link of this one http://forum.xda-developers.com/showthread.php?t=1703746
however i was told to just watch out for it since it's still in development

Please someone with experience in using battery cases on other phones try and answer these questions. How do these batteries actually work? Does it keep the phone's battery under a light charge? Or does it work as a separate battery leaving the built in one unused?
Any unwanted side effects? It's just I don't think if it is good to keep our batteries under charge for too long.

The battery cases comes with a power button, when your HOX has a low battery, you can turn it on and your phone will going to charge same a using a dock station (ery slow).

except those mah ratings are at 3.7v not 5v, so the capacity won't actually be 6000mah
sick of people doing these marketing ploys. makes me sick.

That's awesome news

this actually sounds great, but \i have one question.
In the long term, would this be detrimental or irrelevant to the battery life of the phone?

Best stock size battery

Exactly as the title suggests I'm looking for everyone's opinion on the best stock size battery for the Note. I've been using the Mugen battery but at times the bulk seems too much and I'm interested in trying something stock size that gets me at least a little better than stock battery performance.
Thoughts, opinions, experiences?

it is too expensive? any cheap battery for extend battery life of galaxy Note

I use the "golden battery", the sticker on it says 3250 mAh.. and that power stays at the sticker. It is roughly as good or just a tiny bit better than stock battery.
I get 3 hours 10 minutes maybe 20 minutes less or more each day of screen time on weekdays with stock battery. Let's use this as a standard for me.
With gold battery I get 3 hours and 40 minutes with a variation of 30 minutes more or less.
So it doesn't last 30% more as the sticker suggests.. but meh it lasts as much or a little bit more so I am not bothered with a 15 doller battery I can carry in my wallet as a backup

Do explain why it should be crap? Isn't it known that with most products you pay partially for the "brand name"

Anker cost 20$ for pair of battery's and a charger or 10$ for single battery... Not that expensive but you have most XDA behind it saying it's a good company

I got a 2700mAh Anker off Amazon that BMW Pro is now estimating to be 2983mAh
Maybe I'm using BMW Pro wrong...
Also, it seems to handle charge/discharge better, it doesn't get as hot as stock under load.
Sent from my BBP

I was thinking about it, and it seems plausible that the best stock sized battery for this phone at this moment would be a 2700mah one. If you look at it, the Mugen 5400mah extended battery is just 2, 2700mah batteries linked together.
Until a revolution in batteries is made, I don't think we'll get a stock sized one with a better mileage .

different capacity with stock size battery
It's mean the concentration become higher...

just wondering.
you know the anker charger that comes with the bundle if you buy 2 anker 2700 batteries?
does it charge the stock battery as well?
im assuming it does cuz the batteries are the same size (right?)
just wanting to make sure.
cheers.

Received 4300 and 4800 mAh battery

Now I'm testing this battery. Original thread in this forum (spanish) http://www.todoradares.com/foro/bater-4300-mah-samung-galaxy-t22247.html
At the moment I have not done any charge.
After the first full charge and discharge I will upload screenshots from battery reports.
At the moment, usage is 15h and 9 minutes (normal usage) and consumed 46%
Stock ALF2 rom and cf-root.
Of course, nfc is not available
Now pics:

Extended Battery
The battery seems to be quite bulky. How much did u bought it for?

Ebay 12,99 euro
Yeah it's a bit bulky
I'm using a 3600 battery replacement in my old x10 with feralab rom and the battery usage is 5 days powering off phone at night.

wow that's big..

Yes, but believe me. It's more easier to hold the phone now with one hand.
Sorry, I like more a better battery than design.
At the moment. Battery stays at 3% from two hours ago, using opera mobile with H+.
Needs a little calibration

How much will battery life improve over stock battery?

Does that battery fit inside the SGS3 just like the normal battery? It seems too bulky to fit inside with the cover. If it fits correctly then maybe I will buy one.

No. As you can see in pictures, this battery is more bigger than original battery and needs a bigger cover.
But only for the rear cover. The battery fits correctly in his place.

Can you post measurements of the battery? (ie depth of battery and depth of phone with battery inserted).
The only reason I ask is because I ordered a 3600mAh version from ebay (thought it might be a bit slimer, for all it's worth... ;-) ) and the pictures used show some measurements.
See this url for an example:
**** sorry - can't post external links yet - not enough posts... ****
Search for "Galaxy s3 3600mah" in ebay and you'll find a few posts - the user I bought from is called "hightechhk-com"
(h**p://***.ebay.co.uk/itm/3600mAh-Extended-Battery-White-Door-Cover-for-Samsung-i9300-Galaxy-S3-III-New-/261045894976?pt=LH_DefaultDomain_3&hash=item3cc78c3f40)
From quick observation they look very similar.
Also, how doea the back cover fit? Doubt it's up to the quality of the original (or is it?)
As soon as mine arrives i'll let you know how they perform.
Cheers

Good stuff. Please do a comparison step by step to the original one, as in exactly the same daily use and turn off at night if you do with both. Its interesting, I wouldn't buy it myself but I always wonder if these batteries are not that well made than original.
sent with WSGS3

Now, I can't. I'm testing it now. After first full charge I will post screenshots from battery stats. It's too early to say anything.
Please, be patient. Thank you.
I know that these batteries are made with a lower quality. But i'm sure that these batteries doesn't break your phone (tested in x10). I've heard something about gold batteries, but this battery is not a gold manufactured battery. It's from another manufacturer.

Good stuff. Let us know how you get on

What's up everybody, I just ordered these & hoping they'll do the job. I've ordered from them twice before (nexus one, evo 3d), the batteries in the past have held up pretty good but I don't think these have nfc :/ I ended up ordering these cuz' the qcell nfc enabled ones were sold out/unavailable so I didn't wanna' wait, plus I haven't seen a review on these yet so I said eh, I'll try em' out. If you guys are interested in purchasing some for yourselves I've included the link below, the only thing is that you have to pay using google checkout :/

I always use the supplied wall charger that comes with these so Idk, lots of the extended battery reviews on here are the same voltage & they seem to be doing pretty good.

It's not the charger which matters but the phone itself which charges the battery, it's aiming for 4.3V as that's what it thinks it should have as the stock battery is designed for that. Although I haven't heard a single case of these 4.2V batteries having problems with being charged with 4.3V, that last part can be changed in the kernel and the charger chip driver. I'm getting some knock-off cheap battery myself so I'll see how it goes. This particular one seems quite steep in price @ $30, with proven ones like the PolarCell 2400mAh going out for half the cost.

you won't see the affect right away from overcharging. I use to play with a lot of batteries from RC, overcharging something we use to do get slight edge and boost at start. but it does have long term damage to batteries, specially lithium based. some cheaper batteries even catch fire.

Alright guys, got the batteries in the mail today, charging one & will report back later

Li-ion batteries have an overcharge protection circuit built into the battery pack itself and should prevent this from happening. If everything is working as intended, it should be impossible for the phone to overcharge a battery. That's not to say the protection circuit couldn't fail itself.
And I too played with RC batteries and you really can't compare those batteries with these. Different types of battery with different methods of charging.

Highest slim battery in the world for i9300? 2980mAh Battery X-Level

So I was going through eBay AU and I found this 2980mAh battery at 3.8V by a company called X-Level (not sure if it is by X-Level but this but check it out!) and I wanted to share this with you guys.
Here's the link -
I just ordered one and I'm going to check out if this does lasts longer than the stock battery 2100mAh at 3.8V. I'm also going to compare it to another 3rd party battery (with no brand, *l'll post link of this as well below) that is 2300 mAh battery at 3.7V. Has anyone tried this yet? I'm willing to post results as soon as I receive my battery.
*Here's the link to the other battery I mentioned above -

Share your results please :beer:

And oops, forgot to post the links to the batteries. Updated OP.

Anyone have any prior knowledge of the brand? For that price I doubt it's going to be good.

If anybody has experience with this, also chime in :good:

You'd think at some point people would quit falling for these scams, but I guess not. There's no magical battery technology out there that allows a manufacturer to pack more capacity in the same size space.

thank you for that information. if this battery is not what it claims to be, I'll ask this thread to be closed.

Companies have been working on better battery technology and it shouldn't be much longer before they start showing up for sale to consumers. That said, this isn't anything more than a cheap knockoff with a different label.

Completely forgot about this thread, my apologies. However after usage I can tell you that this may be a very good alternative to stock, cheaper, whilst offering similar performance. Definitely not 2980 mAh though, however it is not a terrible purchase for $10.
Also the battery seems to fall out very easy when you take the back cover off, it does not fit snugly.
