If you want an official one, go with Samsung's 2000 Mah.
If you would something else (fake), it could potentially ruin your phone by blowing up or melting.
If you look around, people have done tests with 3000, 3500, 1800, and original 1650 Mah.
The only one that actually lasted longer was the 3500 one.
So if you would like my opinion, either Samsung's official or 3500.
Hope this helps,

2000 mAh is not enough for me. I want the highest capacity battery available for S2.
Which 3500 mAh one is the good? I read several reviews, but they are mixed. Some say it's really 3500mAh, and others say it's fake.
So which is the highest capacity extended battery for S2 that is not fake?

Its a 50/50 chance. But I don't know any official version of the 3500 mAh battery.

I'd guess, that none above 2000 mAh keep their promises. I got a 4800 mAh battery from mbuynow and it actually has about 3200 mAh (measured with battery monitor pro). This value also seems more realistic, when I look at the size of the battery. As the capacity is based on physics and not magic, a real 4000 mAh battery needs to be twice as large as the 2000 mAh battery from Samsung. So the size is a pretty good indicator for the real maximum capacity. A real 4000 mAh battery should be at least 14 millimeters thick, as my Samsung 2000 mAh (you can't have enough spare batts ) is 7 mm thick.

New 1750mAH for i780?

I was crusing the ebay sellers and i found a place that sold New 1750mAH for i780.
have anyone tried them? i want to bye a new one but the 3000 mAh battery i have seen i don't like becouse of the size i guess if the 1750 mAh battery is good it will get me alot more playingtime than my 1000mAh i have now (wich i don't even know how old it is as i purchased the phone secondhand a couple of days ago (like it very much so far)
I have the 3000 mAh battery from Mugen Power and it's great. Great quality, same as other batteries from Mugen I bought. Even the extended cover is not bad - it makes holding the phone much safer and comfortable.
Ok maybe i have to surender, but i have a Q when i *#0228# on my i780 it says i got a 1450 mAh standard battery but under the cover it says 1000mAh
and replacement batteries i found online is 1200mAh
and then we have the 1750 i found and the 3000
WHAT is the original battery? 1450 or 1000?
if i got 1450 today and i bought a 1200 i will get even worse workingtime out of it...;(
The original battery is 1000 mAh. I can see 1480 in the test menu with the 3000 mAh battery.
Well then if original is 1000 then a "originalsize" 1750 mAh would be a great improvment in capacity (I know now what the 3000 mAh costs it = more than i bought the phone for)

Anker 1900mAh battery?

Hey guys browseing Amazon or GS2 accessories and I came across the Anker 1900mAh battery.
Now ive had the Anker 1900 on the Sensation and its legit a beast of a battery with extra juice, anyone used this for the GS2?
why not just wait a few weeks and buy the proper 2000mah battery??
iam sure samsung would have made a battery this size if possible rather then build extra back covers due to the 2000mah battery they have designed
basically i dont think anker could squeeze another 300mah into the battery at no extra size , its probably not what it says it is and i would go the official route , i have found all these cheap batterys to be useless in my times of owning mobile phones
to sum it up just buy the offical 2000mah battery from samsung or the bigger one from mugen if you want better battery life
look for anker 2300maH on ebay for $12-14 . buy it and make a review
tempted!
im very tempted. amazon uk has an offer for 2 and dockcharger and travel charger for £13. Even if its 80% of original battery i would be happy. But seems like a new release..not 1 review...
I would get the official samsung one but i have the perfect a leather, carbon fibre cases. would it fit in there? i don;t know...will i find an equivalent case that fits it...i don't no. If only if they had a demo version with new battery in a highstreet store i could try putting my case on,
ohh this make has had some reviews from same phone and different phones
im not advertising lol, just discussing reviews

probably not even half that capacity..
I try the anker battery and doesnt work for me. That battery is bad quality because I charged and when the phone was in 5% the screen staring flashing. The phone reboot when is in 5%. I return the battery and they gave me a refund.

Eug measured the capacity one of the spider foot batteries as 2413 mAh.
Even though it is well under the stated rating there is nothing that touches it for value. USD $10 for a 2413 mAh battery is a fantastic deal.

Go on expansys if you are in the UK...they have them for sale on their website
I ordered an anker battery set. should be here in one or two days will report back
I ordered it, nothing to complain but follow my feeling its not like 1900mha... same as 1650mha... one more thing universal usb travel charge need 8h to full charge( output 350mha+-50mha)
>>> with me, im using USB cable + universal usb travel and ..... im smell something from cable so i never do it again

Read some really good reviews in the sensation forum. I would try this but its hard to find a seller who ships to Brazil.

yes, i do but its my opinion
My experience will be subjective, but I've been using 1900mah Anker batteries for the last 2 weeks. They are OK. With original battery I get 12-13 hours when everything ON! With Anker approximately 16-17 hours.
is 3500 mah battery better than 1900 mah ? increasing number of mah is better or decreasing ?

More mAh is better. Just be aware that the 3500 mAh spider foot battery is actually about 2400 mAh. At $10 that's not really a problem though...

[Q] Anker 1900 mah vs Anker 2300 mah battery?

Good day all out of thses two 1900 mah & 2300 mah which is better vaule for money and is the Anker 2300 mah battery really that slim it still fits with the orginal SG2 battery cover? In any case I was thinking of getting the 2300 mah battery as it got good reviews.
Thanks to all.
both anker 2300mah batteries but they look different!!!:

also the anker 1900mah looks different and more genuine:
http://www.ebay.com.au/itm/2x-Anker...565191?pt=PDA_Accessories&hash=item4aacda4387
i dont know what to choose im stuck same as you.. i want the extra 400mah but will i get the extra 400mah or will i get even less than 1900mah !!!
Yes Im aware of the other batteries same manufacture as I see it.
Just wanted to know which is better the 1900 has good all round reviews as for the 2300 not heard to much on this one myself, more so some site claim it (2330maH) still fits with orginal batter cover .
I'd personally go with the 1900mah ones.
Every battery with more than 1900mah while still stock size I've seen reviewed has actually had less than mah than the stock battery.

Thanks for your input D3 like I said there not much (or Im looking wrong places on net) on reviews on the 2330maH battery, at under 10 euro/pound I may just order the 1900maH one still no rush.
Do you actually believe some company managed to stuff more capacity into a battery without increasing its size? There's a reason samsung's 2000mah battery is thicker, don't be fooled by the rating on a non-oem battery, its fake all the time http://batteryboss.org/

Then im sure samsung which is one of the largest electronics manufacturer in the world would of figured this out by now, not some unknown anker company. Don't be fooled by a label on a battery, even the popular seido/mugen batteries fall short of their ratings.

anker is not an unknown battery company... they are known for their high quality batteries...
and its proven multiple times that the 1900mah battery is 1900 and even 2000 for some ppl....
i do think the other one is fake though (the 2300 one)
Im thinking of getting the 1900 battery together with the anker charging dock you got a 2pound discount!
Went for the 1900mah placed order thanks to all
can someone tell me if this is the real genuine anker 1900mah battery that everyone is getting here on xda?

As per the photo yes but if you have not done business with said dealer drop them a line to find out if these are genuine anker batts.
This way you'll have digital proof if they turn out to be fakes and you can take it up with ebay there after...

Wait does that need a new back or is it the same size as the OEM battery? There are some good comments under his feedback for this battery.

Its the same size at the original.. but seems fake idk
hmm has 4.35v vs 3.8 oem and has plenty of positive reviews, tempted to buy it
4.35V just the max charge, same with OEM battery. 3.8V is the nominal charge...just another fake battery

Why would voltage dictate capacity? They have nothing to do with each other.
So who's gonna be the brave soldier and buy this?

they don't. wtfmateim65 implied in his post that 3.8V and 4.35V made a difference, i was trying to clear up that misconception.
since the battery is the same size as OEM, there's no way that this battery is 3250mAh as claimed. also, if you look at the back of the battery it says 4.2V...just another fake like i said.
this seller is also implying in his auction that these batteries have short life, and to ignore it because of a "memory effect" that li-ion chemistry batteries do not have.
all in all, would not trust the rating, but it may certainly be a good replacement for the stock battery -- sans NFC and the extra mAh claimed.
Damn wouldn't that be a nice deal

I´ve checked the negative feedback for the last months of that ebay-shop and other which offer stock size monster battery´s, and some sounds like this: "misrepresented strength of battery", "Bad battery no difference between the original one and this battery very poor", so it seems like clear fake mAh strength. :crying:
I think Samsung itself would equip their flagship with a thin stock-sized 3000 mAh battery if it would be technically possible, but i think it is not and all the ebay items are fake. There are a few other battery’s on ebay with similar strength (2850, 2950 mah), and there are also negative feedback about their real battery performance, except the good feedback for fast shipping or something unimportant.
I bought two weeks ago a Polarcell 2400 mAh battery and I´m not disappointed, but also not really happy, there is almost no noticeable difference in life perfomance between the stock 2100mAh and polarcell 2400mAh (+15%), but i think their 2400mAh is real, because the Polarcell is noticeable heavier and like in all corners 1mm bigger than the Samsung stock.

Nexus 5 3800 mAh batteries legit?

Are those Nexus 5 batteries at AliExpress with a capacity of 3800mAh legit? They even claim it's the same size as the original batteries.
No, this is fake... Maybe the real capacity will have a 1500mAh... Search original or replacement of good quality, for example. PolarCell: http://www.polarcell.de/english.html
I second that (what bykumza writes), if the manufacturer (LG) could have fitted a real 3800 mAh battery they would have done that. Often the more modest capacity values are more accurate. I can confirm that PolarCell are very good, well worth the money. The Chinese cheapies often dissapoint.

Actually Nexus 5 and G2 are released almost same date. Nexus 5 has 2300 mah battery and G2 has 3000 mah. I bought G2 battery and put it in my Nexus 5. It fits but it needs ~1 mm space which is not a problem for LG to do it! But they did not! That company did not put 3000 mah battery in nexus 5 which could have been the bestseller because of price/performance and put 2300 mah in it so they could sell their ****ing G2s with great battery life. So no they would not have done it even if they could. Today companies do not do so much things that they can, we just can't even imagine. Intel, Nvidia, Qualcomm, Samsung , apple and other mobile companies are good example. Why on earth can't mobile companies like apple put bigger batteries in it's super high price phones? Juts why? Samsung managed to put 3600 mah battery in 5.5 inch phone which is smaller then iphone 6s plus or 7 plus which has ~2900 mah and takes 3 and a half ****ing hours to charge it!!!!

And... Why not G2 battery? I need a replacement to
Thanks
Fitting G2 battery requires some hardware modification, which I frankly don't feel like doing.
I just wonder which battery is better, a PolarCell one (someone recommend in previous post) or OEM one.
Polarcell is reportedly one of the best alternatives and has a slightly higher capacity than the original cost can say that comes out more or less the same as the original.
Here, unfortunately, you have to answer on your own if you want to take a chance and buy a replacement if you prefer a standard solution.
