Most aftermarket batteries give about 60-90% of the OEM battery's lifespan, even the extended batteries only give a little more.
I doubt it will give more life than the OEM battery because until micro battery cell technology is researched more by Sammy/other battery providers, most batteries give life based on size.

Welcome to the world of marketing. If you advertise a battery on ebay as 2900 mAh, and one as 2500 mAh, which one will sell? If you sell a bettery on ebay as 2900 mAh, but it's no better than a 2500 mAh battery, how many people are going to test it and manage to get their money back? You can find all kinds of "off-brand" batteries on ebay that miraculously have better performance that OEM and/or brand name batteries. How is it that these small nameless companies can always figure out technology to make something better and sell it for less than the big companies with bigger budgets? As xAnimal5 suggests, if it's physically the same size, it's very doubtful that it really performs any better than the original.

I just asked whether someone has tried it yet, I wasn't intending to buy it any time soon.
2500mAh is already an amazing amount of juice, 2900mAh seemed a bit unrealistic to me too. But considering the price it's worth the bet I guess.

I'm afraid to try these batteries cus it would royally suck if the battery damage my phone in the process. But, if Sammy were to come out with one, I would defiantly buy one.

I bought one of them.
I'll keep you posted on the results!

I like living on the edge.

My batteries came in - they claim 2600 mah, but they really aren't very good.
I'm guessing they are more like ummm, 2000?
Well, for $10 for two of them, can't complain too much.

I have 2 ebay batteries on my Xperia Arc and it works very well.
I bought my white note this morning and I'm planning to get some extra batts from ebay aswell
I think some Chinese products are rubbish but other are great.
I spend 6 bucks on the 2 Arc batteries and I think they are best 6 bucks spend ever.

I think its fine enough to have a 2500mAh Juice, after all such a competent device lasting for a day is not less

Have a 3500mah battery for S2 its unreal the life span its more like 3200mah but still crazy good. For note im keeping stock. Its definatly good enuf but s2 stock fails badly.

So, can you share your results? I'm tempted to buy one of them too and other that claims 3000MAH. I know about those marketing numbers, but keep in mind that they are more related to Chinese batteries. These ones instead are Japanese and many people are getting at least 10% to 15% more juice of them.

Do not buy anything from ecell (linked above) that company overprices low quality good with false claims.
The Gold ones are not cells from Japan but the same cell you get if you buy any cheap china battery.
Feipusi, Andida are easily found & reality is they will not reach stated capacity & will be close/little less than a standard sized cell.
These brands also have no working temp sensor & jst feed constant reading of around 23<>25degC.
Having said this if bought for the right price (4to8USD) they are an ok budget replacement or spare & easily sourced for those in areas with limited sources.
Just don't expect capacity gains & don't pay $15 for a $6 battery ...

and where to find them (mean Feipusi) for 6$?
my friend got Feipusi battery for atrix 2 and it realy do better than stock

Hong Kong, Kowloon. Due to its proximity to Shenzhen it full of this stuff at good cheap prices if shop around a little.
If not in Asia region then you looking at eBay ect, have seen HD2 & Topaz Feipusi on eBay for less than $5 delivered & that gives you idea of real battery value.
Stay away from ecell as they fill adverts with incorrect specifications & charge more than twice the price for lying to you ...
If take a bit time Feipusi for Note should be found for $8<>$9 inc WW shipping or maybe less.
Don't expect it to be better than original in capacity or quality.
A new original cell compared to any cheap china new cell (same physical size) will win hands down. Most people test badly & compare their nice new cell to a half dead original or use testing methods of no statistical value.
Also be aware you will have no working battery temp sensor & cheaper cells may not last long before large capacity loss occurs & cell starts swelling.
For cheap price they are good spares & great for people with no local OEM spares but for high prices you are just giving more money the US & West ain't got to the grinning Chinese ...
Buy and pay wisely ...

I tried this battery, it does have the stated 2900mAh capacity. I have a charger/discharger device that can measure battery capacity:

and the battery does have stated capacity.
I also tried 3000mAh battery which is even better than 2900mAh:

has only 2700mAh.

1900mAh eBay batteries review *Video* *screenshots* *pictures*

Hey guys, I took the plunge and bought a set of these batteries from eBay, thought i'd share the findings with you guys!
Seller posted quickly and I received the batteries within a few days, fit the phone perfectly, lack NFC as expected and seem to last longer than the stock battery! Even better they haven't exploded in my pocket
These are for the i9250 (GSM) model.

Overall I'd have to say I am very impressed with these batteries! only £10 for two batteries and a charger is a steal in my eyes, and I would highly recommend a set to anyone looking for some extra juice out of their nexus!

Thanks for the review. I'm sure the lack of NFC will be a deal breaker for most as it would be for me.

Yeah I can see it being a top feature in other countries where there is a NFC infrastructure in place, but here in the UK we have barely anything to use NFC with, so I'm fine to go without!

Warning chinese batteries can.explode or burn.

I also broke down and bought two 1900 mah batteries from ebay. Paid 13$ for them and a charging dock. Was looking for Anker but couldn't find them.

Am I the only one having problems with these chinese batteries?
Well no actual problems since I dont own one, but still: I dont trust 'em. Not one bit.
I bought a >500€ phone and I wont install a cheap replacement just to save some bucks. Worst case these things ruin the phone or even worse hurt me...
Really cant understand it to be honest. No risk I want to take just to save some money and gain a few mAh at best.

So how is the batterylife after some days of usage?
What about the charger, getting hot loading the original battery?
Did you notice something negative about them now?

Hopefully those that against the so call chinese batteries, please rephase them as non original batteries, many batteries are chinese made, even some samsung galaxy nexus batteries are made in china, and nokia, motorola, even HTC.

I've had two chargers die on me, the second one died with a big bang and tripped the circuit out leaving carbon scoring on the cable. I have been refunded for the charger but now have no way of charging the batteries except for putting them in the phone so they're next to useless (would only be of use as quick charge spares when low on power to swap out).

Seriously????? Obviously when referring to "chines batteries" people are referring to the cheap eBay crap. Despite whether they work or not or explode or not do you REALLY think they go through "QA" or "certification?" These are (usually) cheap Chinese knockoffs where if you are lucky you might get what they are actually rated at but if you believe these $3 and $5 batteries actually go through any sort of "QA" you are hallucinating. They put what they want on the labels but don't believe for a second any agency in China tests or certifies them for anything and even if they did I wouldn't trust them for a second.
If you or anyone wants to buy $5 batteries, that's perfectly fine, I've owned some myself, but don't think for a second because they say "certified or tested" on them that they really are.
I've bought cheap camera batteries that look identical to real $80 Nikon batteries but believe me, other than looks they don't even come close.

then it's you who to blame, you get what you pay for, and don't expect a well known brand for $3-$5, and you should know better, stuff like batteries and medicine, alway buy from people and place you trust.
that being said, there are many batteries, not brands like samsung, sonyericsson etc, but brands from china and hong kong like yoobao, speed, yperfect, momax and goki are cheaper alternative, that do go through certification and QC, so don't treat all chinese batteries cheap knock off, they are not fakes, just third party alternative.

Chinese certification?

I bought these about two weeks ago, and I am very impressed with the batteries. They have provided consistently longer battery life than the original, whether it will hold onto the charge after a few hundred cycles is a different matter.
However, I would recommend getting a different charger. The one supplied blew a fuse because it was heating up so much. It might be a faulty one, but given how cheap these are, I would urge caution with these chargers.

Was in China recently and purchased this Power Bank.
(Sorry can't post a link to the device due to my new status on XDA. Just search Pisen - Power Station 10000 mAh
It's 10,000 mAh which can recharge your phone 4x over! It's basically four 2,500 mAh batteries in one. Have had no issues with it so far.

Yes,it is very hard to buy the real capacity power bank ,because the market is so complicated .The price range is huge .Quality is very different .But you can still buy the satisfied power bank from Chinese supplier .

Can you tell, if the discharge rate is high, or does it keep the electricity for months? I'm planning to get a Power Bank myself, so I gather some information.

i was thinking about getting this one from Anker
http://www.amazon.com/gp/product/B00BLCS724/ref=ox_sc_sfl_title_3?ie=UTF8&psc=1
looks good, and has a built in micro usb plug, so you don't have to carry any cable with you.

[Q] Any good SAFE and NOT-chinese power bank?

Ebay has so many kinds of these power banks with huge sizes. I doubt that is real, so i wanted to ask if anybody has reasonable size (not over 3k or 4k mAh), that is safe and not made in China?
Buying something Chinese is really bad, literally every thing i have from china has broken in the first day. And i do not want to buy something electronic like that battery pack from china that could explode or something. All i need is a power pack that could charge around 75% of my battery. I do not need some huge thing. I simply can not get my phone to last throughout a normal school day on normal usage.

Look at the ones Anker offers. They are not cheap but worth every cent.
I have got a large one with about 6000 mAh. But they have also got smaller ones.
Most of their batteries are able to deliver high charging currents, which enables you to charge your phone just as fast as on AC power.
I can really recommend Anker.

Though I read your "no china" criteria, I would still suggest you to try out the Mi Power Bank. I have been using it for almost 4 months now, and although I had my own reservations regarding a Chinese product that could (literally) kill me, it has been terrific till date. It charges up the phone at almost the same rate as the wall charger, and it itself charges up pretty fast. Comes in two sizes- 5200 mah and 10400 mah. The 5200 mah power bank is what I have, and it is sufficient to fully charge my N5 and charge a Grand 2 upto 20-25%. Plus, it is a lot cheaper that the power banks made by Sony and likes.
Btwn..It actually comes from Xiomi, the makers of Mi3 which has been one of the most successful phones in 2014. This is the only thing I relied on while getting the power bank, and boy am I happy with it.

I didnt knew sony makes power banks too, and thanks for suggestions!
Also, during decharging, does the power bank heats up? (When i charge my phone with the power bank)

No it does not. You can see some YouTube reviews if that helps you. Not sure if you are bothered about it but the finish of the body is the best I have seen on power banks.

FYI

I have NEWNOW power bank. I can charge my n5 for about 5 times completely. Its capacity is 10400mAh. Has 1A and 2,1A charging ports. With the 2,1A port charges my phone fully in about 15-25 minutes. Highly recommend!

It's impossible to full charge the phone in less than 30minutes, certainly not at 2.1A.
Also that looks like a cheap Chinese charger to me. When you see 10,000 maH ($20) for less than the price as most 5000mAh you can assume that they lied about the specifications.

Xiaomi asks 19$ to ship Mi Power Bank to Romania from its European hq! Isn't that a little bit too much?

I've read through this thread because I have the same question. Are there any power banks actually not made in China once you scratch all the "it's made in China BUT" comments?

I was in the market for a large capacity power bank and really liked the look of this one on Amazon. Shipping was very fast as it was fulfilled and shipped by Amazon. In this review i will go over the Features, First impressions and Final thoughts after using the power bank for some time.
Features:
Ultra-slim design with a hard plastic & aluminum alloy construction
High capacity 20,000mAh
Two USB charging ports (5v-1.0A/ 5v-2.1A)
Micro USB input for charging the power bank (5v-2A)
Blue LED digital charge indicator
Built in over-charge, and short circuit protection
Dimensions: 6.8 x 4.8 x 0.5 inches
Compatible with any USB charged products such as iPod, iPhone, iPad, Android tablets and phones, ETC.
First impressions:
After receiving the power bank the first thing i noticed and was pleased with was the packaging. When you buy a product you expect there to be in professional and quality packaging and they definitely did that with this power bank. After unpacking the power bank and holding it i was very pleased with the aluminum alloy construction. When researching power banks the materials used was one of the main factors for me choosing this one over some of the others on the market and im glad i did, In the hand the build quality and construction feels premium just like my HTC one and iPhone. While it is a slim unit i would not say its the lightest power bank it is after all 20,000mAh capacity which is a larger power bank . If you are interested in smaller lighter package you will also be shrinking the battery capacity so that was something i wasn't willing to compromise on. First thing i noticed during use was the digital LED capacity readout. This is a premium feature that also was a top factor for me choosing this power bank. With a quick slide of your finger across the read out screen you can see exactly the charge you have left, No more relying on the few led lights the other banks have to judge how much juice you have left. Overall my first impressions of the power bank was very positive. Between the premium build quality and features included i was very happy with my choice. Amazon LINK
Final Thoughts:
After using the Power Bank for some time my initial opinion did not change, In fact im not sure how i lasted before without one. The quality of the unit is outstanding, Being constructed from aluminum gives it some serious durability, and looks brand new after heavy use wile camping, traveling, beach trips, and school/ work. The battery capacity is outstanding, as a power user Ive always found myself killing my phone battery far to early in the day and now i always have a charger even wile away from on outlet. Ive also found it very useful for camping trips and power outages due to the large capacity you can charge many items on one single power bank charge which is very handy in those situations. Overall am very pleased with my purchase. Between the stylish build, quality of materials used and the overall charging performance i would recommend this to anyone in the market for a power bank. Amazon LINK

I bought 3000mAh for my Nexus 5 and both times I used it - it had problems. Once I unplugged it, within few minutes my phone went off, no buttons worked, nothing, dead. I kept pressing, holding different combos until it rebooted somehow. Never had such problems before, but both times I tried to use power pack. I did read online that other people have had similar issues by phone getting confused and shutting itself down. So - no more external packs for me

I love this. 20000mAh is super high capacity power bank on the market.
the aluminium alloy looks very classy.
But how many times can it charge for Nexus,or other hot android phones like Samsung note 4,HTC M9,etc.?
I think charge times is a very important info. but it wasn't provided here.
and I think the power bank might be a little too big. Am I the only one who have such thoughts here

I did read online that other people have had similar issues by phone getting confused and shutting itself down. So - no more external packs for me

Yea I can see how that would be annoying. Haven't had that issue with this pack.

I love this. 20000mAh is super high capacity power bank on the market.
the aluminium alloy looks very classy.
But how many times can it charge for Nexus,or other hot android phones like Samsung note 4,HTC M9,etc.?
I think charge times is a very important info. but it wasn't provided here.
and I think the power bank might be a little too big. Am I the only one who have such thoughts here

Yea it is a bit on the large size but you really can't help that with the large capacity, this brand also offers smaller capacity aluminum banks. As far as times goes its depends on the USB slot you use as there different amps but its very similar to the stock charger time wise. Also all phones have different battery sizes, the n5 has a 2300mah battery so you get around 8 - 8 1/2 charges on a full power bank.

Ordered two

I got one and test it for capacity, it is great value for $/Ah. it cost 38$-39$ at ebay and aliexpress
the size is good, if someone need smaller size/less capacity vinsic have other models.
from the cell i learned they use high grade LiPo cell from LG , and in small ones they use Samsung 18650 cells, not some fake chinese cells...
It have real ~13500mAh (20000mAh * converter PCB Efficeincy factor ~0.67) capacity available for recharge devices.
if you want to know how many times you can recharge your gadget (phone, tablet etc...) use aproximate calculation
13500mah / your device capacity * device charging efficency 0.8 = aproximate charging times.
for example i have 2600mAh battery in my Galaxy S4 so it will be
13500 / 2600 * 0.8 = 4 full recharges. It give me freedom to use cell phone without outlet for really LONG time.
I can recomend it...

Wooow 20000mah it s awesomeee,I was looking for an enourmous one to take with me when I do some camping...From the pictures looks very well built and i like the battery indicator,wich contributes to assure you about the quality.I had 2 chinese no brand powerbank,but they looked cheap in building quality and engeneering chose, like the bicolor red green led to tell the remaining life (I don t need a red led to know it s 0%,a yellow one with the red and green led lighted up to tell me the 15 or else % could be a better use of bicolour led ) or the stupid second one with an uv led that was meant to tell battery % ,but likes was written in manual to tell if you have a fake banknote or not (ahhahh how stupid is that???).
I want one, they produce even other power banks looking from they re site,the wood one is looking awesome, and other accessories ,all looking goods and not resembling to other brands. So they could be a serious brand . I look if I can get this one and they re car charger from amazon (2 usb 4.8A ) i need it for my nexus 5 and nexus 7, then I will tell you about the quality after some stress tests

How long does it take to charge?

I'm so getting one of these when I get paid again. I have a 10,000 mAh one, but it takes freaking forever to charge.

Is the battery capacity indicator activated by touch?

It holds 20 amp hours and uses a 2 amp charger so 10 hours.

Great! Is it hot during charge?

I got one after looking into it and I'm so happy I did .I've a pile of packs .most 1200. Needed a bigger one and I'm impressed with the quality and it's storage once it's been cycled a few times. I used a one amp charger as it's all I had but bought a two amp which it needs .buy one they are superb. It's like an Apple accessorie with the aluminum unibody design. Gives no neat charging or discharging. Get a kindle case to keep it like new

I keep mine in my computer bag while traveling so it serves the purpose the way I was hoping.

Now that I own a nexus 6 this looks like next purchase

I want this one but it seems so big, I guess I'll just have to get it and try it out.

Looks really well made for being a battery.
