Guys when will you stop posting crap batteries?
It is so cheap that there is not a slight chance of being exactly as described...
And it is ridiculous to believe that, this battery even though it is the same size with the original, has a 2430mAh capacity!
Big capacity automatically means bulky battery.

They're shipping now (or soon), so wait and let's see

Hmm during Nokia 7650 early days some of those high capacity battery really serve what they say with double the mAh. Now, I'm not so sure. Most probably a fake

what a fraud. is it even legal to lie about the product specifications in this way?
by the way.. thanks for telling me this! I appreciate this! (A lot)

2x1900mAh Battery + Wall Charger = £10.25 free p&p

Thought I would share this nice find.
I wasn't too sure about it, however the seller confirmed they would work, so i took a punt.
1900mAh Battery x2 + Main Wall Charger for Samsung i9250 Galaxy Nexus
They fit perfectly in my O2 UK version of the Samsung Galaxy Nexus
One in my phone right now, the other in the wall charger.
So they aren't NFC's... but I am thinking a tenner for two batteries and a charger, cant be bad. I'll keep an eye on the charger so it doesn't burn my house down.
I am running a calibration using Battery Left PRO, to see how it compares with my stock battery. My stock has 25hrs full life

Thanks for sharing this find! Does the battery fit into the GSM version as-is or does one need a special cover? I am asking as the normal battery only hold 1,750mAh.

Nice find for those who don't plan on using NFC. Let us know how well they work.

Will do... I am using one now, and as I said, calibrating it so I can see how much they hold compared to my original

Thanks, for the post, I'm interested in knowing if they hold as long as the stock battery or if they just printed a 1900mah on it. There's another ebay ad for a 2300mah which looks exactly the same as the battery here. I'd be surprised if they can get that capacity without increasing the size of the battery.
Of course for the price, I'd just be happy if it had the same capacity as stock.

Definitely need something like this, I couldn't care less about NFC at this point.

early rough calibration, is telling me it has at least as much at the stock.
I plan to calibrate them both, and i do it thoroughly until "accurate" so it'll take several days.
but i shall report back
defo this it was a wise investment at just a tenner

Wonder if they will work on the USA LTE version

day 1 update is...
it is at least as good as the stock, however i think it maybe better.
Although saying that I haven't really caned it yet... so hard to say.
I would confidently say that it is on par with the stock AND two batteries... and a wall charger (which is very useful) for £10!!!! I would recommend it

What do you think?

Where can I find just the external battery charger?

I bought two of the extended batteries, and want to get a charger like comes bundled with the standard battery for them.
I have heard the standard sized battery charger will work (with the exception the lid won't close) so does anyone know where just the charger can be bought?
On a side note, It seems it would had been much cleaner if the media dock had a slot on the back for charging a battery.

I brought this and works a treat, any help?

Saw that, and it would probably work..but I was hoping for a el cheapo charger, without paying for batteries I don't need.

I've been looking for the same thing. I could not find a GN specific charger without getting a battery too. Saw lots of them for other devices though. This phone is brand new so there will probably be a bunch of aftermarket external chargers out in a little while. I did find this Anker Universal. I might give it a try.

Thank god I got confirmation. The batteries and charger that grizlore recommended is for the GSM version. Just in case you don't know, the GSM battery is not compatible with the LTE, vice versa.

After a couple days it works pretty good. I like how you can use a car charger to charge it, or use the battery to power another USB device.
For about 8 bucks its a good value. The only annoyance is lining up the contacts each time I swap a battery.

Tmobile Samsung Galaxy S II battery same size as Galaxy Nexus LTE battery!! *2/28*

I just received my Hyperion batteries (a whopping $35 for 2 + charger, ack! ) and they are the same size as my brother's Galaxy S 2 batteries! They even say Galaxy S II on the back of them!

I think the Galaxy Nexus battery sellers are totally gouging people and marking up "Galaxy Nexus" batteries because it's for a "flagship" phone! So, we can save some money by buying SGS 2 batteries since they both look pretty much identical and are the same!
These ones look like they would fit perfect! And cost only ~$4 each compared to the "Galaxy Nexus" batteries which costs $18 each!
http://www.ebay.com/itm/3x-1850mAh-...ccessories&hash=item4160c349f9#ht_2899wt_1163
They even have the NFC Antenna built in!!
More pictures:
PLEASE NOTE: This compatibility is between the LTE Galaxy Nexus & the TMobile Galaxy S II
I'm guessing that the battery for the Sprint Galaxy S II should be compatible as well. Anyone wanna buy the Sprint ones and let us know? It's a $12 gamble.

Just an FYI, i have an I777 and ordered similar batteries that said they have NFC but didn't. So don't expect for your batteries to have NFC; however, i can say that they do deliver on backup time.

So it looks like the sprint sgs2 has only 3 contacts and while the battery fits, its about 1/4" shorter. So it would work with a spacer to keep the contacts of the battery touching, but not a direct fit

Mostly likely not, battery voltages are never constant. They have the highest voltage when they are fully charged and then it slowly drops. Since these Chinese knockoffs almost never live up to their printed "specs" the real voltages are probably lower.

Well, my friend's already been using his Tmobile SGS 2 batteries for about a week now and they work just as good as the OEM batteries.

So, really, they have the NFC antenna?!

Im considering buying them , any decent reviews on them yet ?

I have a gsm nexus and the gs2...the batteries are not the same...galaxy nexus have a taller battery.
Edit: now that i've watched closely, it says on the battery label T-mobile version...please note that the internacional version of samsung gs2 does not fit the gsm nexus.

$3 + $1 s/h = $4
notice that it says: "noar field communication"
this could still have the NFC and be a type-o or it could not have the NFC. We won't know until someone buys it and tests it. I may buy it myself in a few weeks. I just bought 2 x hyperions for way too expensive ($18 each!) and those don't have NFC for sure.
If not having NFC is no big deal to you, it might be worth buying one to test. Don't forget to let the community know!

Just bought one, I will give it a try and let everyone know.

Long story short: It really seemed fishy at first, then I had used the battery for 11+ hours and battery life is at 33% atm :good:
I watched youtube vids for at least half an hour, played real racing for an hour and every often I kept on browsing the web. Battery is AWESOME and looks like it really is 1950mAh. My brand new Samsung original battery lasts shorter than this battery
The battery comes in a nice bubble wrap with a good quality sticker protecting the battery pins. Really can not understand still how something like this can be this high quality yet this inexpensive. Gives my $29.99 Original battery a HUGE run for its money

Used this battery for almost 2 weeks, so far so good. :good:

thanx for the info on the battery.. will get one for me and one for my wife..

i bought this battery a month ago nothing special
just a cheap second battery and in no way 1950 mah
don't get me wrong for 3 euro it is awesome

The only fear is from explosion or something like that with replaced battery.

Just bought 2 from a seller on fleabay uk at £3 each, difference is mine dont have the samsung brand but instead have smaller "For Galaxy S2" printed on both sides, maybe samsung is finally doing something about all the fake sammy batteries being sold and genuine buyers getting stung, i fully understand that oem batteries are in most cases cheaper and can be as good as the original but if it says samsung it should mean genuine samsung and not have a half truth half way down a sellers listing saying packed in bubble wrap not a genuine product and no mention of any warranty whatsoever, still fleabay wont enforce the "genuine non genuine" listings because they claim they cannot police every seller !doesnt stop them taking their fees from every seller though.

haha awesome

yap, its cheap ,
I buy some different brand for S2,
but stock bat. usually have more cycle life than other :cyclops:

Huh! Going to order this..
