I've recently updated this thread with a link to the original Yoobao website. It is in Chinese but lucky for us Google has a translation feature that worked out very nice...so if you want to take a look at the Yoobao brand for yourself I've posted a link so you can take a look at all their products for cell phones.

I found this 2800 Mah hour battery with door for the Samsung Epic 4G on Ebay and I just finished posting the final review up on my youtube page. This is a nice medium from spending $50 on a 1600maH battery that isn't going to give you much improvement and spending $70 on a humungous 3500maH battery.
Here is the link to the youtube review I just recently uploaded if you wanna take a look at it for yourself in detail!
URL: http://www.youtube.com/watch?v=Al_po8oanz0
The name of the company is "Moretalktime" and you can look for him on EBAY to purchase this extended battery along with batteries he has out for various other phones for all your friends.
I'm in the middle of conditioning the battery and thus far it took me 13 hours to kill the battery from 100% out of the box with everything turned on and I even left the LED flash on for the last 3 or so hours to get it to die...after another cycle of coditioning (this bieng the 2nd..ish cycle) I took it off the charger with 100% battery Wednesday night of 11/24/10 at 8pm...and my phone just died earlier today on Friday afternoon of 11/26/10 at 1pm GIVING ME 41 HOURS OF BATTERY LIFE WITH MEDIUM USAGE!!! on a 2800mAh battery...still not done calibrating...that's only the 2nd cycle...more to come....just wanted to give you guys an update!!!
Yes that's right people no BS I got a lidgit 60+ HOURS OF MEDIUM USAGE! on this Yoobao 2800mAh extended battery...check out my latest youtube video for details and the final review!
DIMENSIONS:
1.5cm back to front with stock battery cover.
2.0cm back to front with extended battery cover.
30,000+ views!! thanks errybody don't hesitate to leave a comment and leave me a quick thumbs up if I've been of any assistance to your battery life situation!!
Let me know what you think, questions, comments, opinions about my results so far!?!?!?

Well this is very exciting news! Maybe now I will be able to get through the day without crippling my phone. Can't wait!

Link please?

Wow look at that whopper of a battery!
Makes the phone like a giant brick. I'm extremely wary of extended batteries from China, and would like to see the battery tested and what the actual mah level is.

holy ugly. I'll just carry a spare if I need it.

That thing is huge and I bet it is not comfortable when using it.

Just ordered mine from the above link for $30.50 + 7.00 shipping.

The back cover has the same soft touch matte finish as the stock epic battery cover has.

Personally I don't mind the extra bulkiness, I just wished it was even like this:
Does anyone actually trust eBay batteries. I'm not so worried about the rating as I am about them exploding.

I didn't see this battery but I've bought batteries off Ebay for my old Samsung Moment and for my Epic both of which were the stock sizes and OEM...they both turned out great...is this battery off Ebay also?

$40?! Forget that! I just read his little speech on how those cheap $10 batteries are garbage, his are the best blah blah blah...the same story EVERYONE says about everyone elses products. I wrote enough people on eBay who bought the $10 battery from this guy http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=310271079152&ssPageName=STRK:MEWNX:IT that eBay stopped me from writing anymore people for another 24hrs I got replies from at least 1/2 the people I wrote who've had them for about 3-4 months and everyone of them ranted, raved and said they were quite surprised at how much better their battery life is compared to stock considering what they spent. Just one example:
Dear sirtecknight,
I was curious to see how your 3000mah battery is holding up? I'm considering getting one of their 3000mah batteries for my Samsung Epic and wanted to make sure that it actually increased battery life for you after charging.
- m5james
I am pleasantly surprised with the performance and, to be honest, quality of the 3000Mah battery and cover that I bought from this vendor. The 3000MaH battery lasts almost exactly twice as long as my 1400Mah batteries do. Also the oversized battery cover was actually alot nicer than I was expecting.

The last time I was at the local Sprint store (replacement phone), two of the guys working there had EVO's and each had a seperate style of extended cover just like the two posted on this thread, and I prefer the version that is thicker from head-to-toe vs just a bump over the battery portion only. I've got an eBay battery in the mail and plan on grafting the i9000 bump onto my stock Epic cover and then wrapping the whole phone in 3M DiNOC carbon fiber.

I don't really get it you start off saying forget that the $10 knockoff batteries are cheap but then put a quote from a happily satisfied customer...??...and these batteries are 2800maH so idk which person your talking about but this is not the same company.

You're missing the whle context of my post. I said forget spending $40 on a battery and then stated I have proof otherwise about his statements, therefore disproving what the seller or the $40 claims in his entire ad in that the $10 batteries since they have in fact turned out to work quite well. When I say cheap about the $10 batteries, I was referencing price, not quality.

Ight comprende good point...they don't exactly seem that lidgidimate, but you just prooved me wrong I guess

I'm not trying to prove YOU wrong. My point is that the eBay seller with the $40 batteries is claiming that the $10 batteries are all garbage, which I've read otherwise. Today I charged my stock battery to 100% using the wall charger, reset my battery metering through Clockwork, run a bunch of streaming and video apps (Pandora, Slacker, TuneWiki, Skype, Fring and have a movie playing all at the same time) to kill the battery, turned the phone completely off & recharged and now I'm killing the battery again....timing the cycle each time. Once my 3000mah battery arrives, I will be doing the exact same thing so I can give myself a before and after.

2430Mah battery (same size as stock)

Since i upgraded from my htc dream which had a custom japan made 2430 Mah battery iv been searching for the same thing for my O2x and iv found it.
http://www.ebay.co.uk/itm/2430MAH-F...069?pt=LH_DefaultDomain_3&hash=item2eb76a1fad
Its the same asize as the original battery so no gay larger backs for the phone just longer life and more time gaming and browsing, just dont buy them all ill be getting one in a couple of days.
Since they have the tech to put more power into small sized batterys it makes me wonder why these big phone makers dont use these higher capacity batterys instead of giving you some peice of **** that barely lasts a few hours of real use.
Already posted this in the optimus 2x forum but in case you guys dont check that section i assume both version of the phone use the same battery so it should be compatable.

Thanks. I just bought one...I'll update after it arrives. For $20 it was worth a shot.

Just ordered mine tired of my extended battery
To Begin with thanks for the information about the battery . Just ordered one can't wait, i like my extended battery but the case is to bulky and can't use it with my dock so hopefully this battery does the work i guess when it comes in i will test it out. But overall thanks for this thread !

Interesting. Defiently be waiting for some reviews.

I wish you luck -- many secondary market batteries get the higher mAH ratings by a variety of not so good practices the most common of which is listing the mAH obtainable if the battery is _completely_ discharged. The problem with measuring it this way is two-fold:
Your phone(and the battery) should shut off before reaching total discharge -- this renders the usable mAH as a less than advertised amount.
If you manage to completely discharge a Li-ion battery completely, the damages it's lifespan, and can make it dangerous to charge.
I'm not saying that particular battery has any problems, or has a inflated mAH rating. Just an observation on common(unsavory) practices in the secondary market.
I would be very interested if these batteries turn out to have an increased usable capacity -- I have some other projects I could use them in.
references: energy density
a 2430 mAH Li-ion would ideally weigh at least 5.25 grams
and would ideally be 2.73 cm^3 in volume
the above figures do not include the housing and protective circuitry.

I agree with you and the false advertisement of battery capacity ratings out there. If you look at Amazon one particular brand PRODICELL has been accused by many buyers of false advertisement. They list higher mAH ratings than their batteries than they really are. The put their own label on top of the cheaper generic batteries. Not only that, it seems their employees have been posting FAKE positive reviews on their batteries to boost their ratings. FYI. I would be cautious of batteries that claim a higher mAH rating especially if it is the same size as the regular battery.
Note how this one customer tested the battery to determine the mAH ratings were false.

Made in Japan doesn't mean sold with honor. Often you will find a new label behind the stock one with different stats. haha
Only real way to check the capacity is to drain it and record how long it takes for the voltage to drop to the minimum for the cell. It will fall off very fast.

I can't wait to see the results on how long this battery can last. If this thing can last a full 24 hours with moderate use then this is the battery for me. That gold wrapper on the battery looks very appealing but for some reason it makes me think this battery is BS (You can wrap a piece of **** in gold, but in the end it is what it is). Damn, it's been a very long time since I have purchased something actually made in japan.

I suspect it is built similar to my 1980 andida, where it is slightly larger and heavier than stock, but still able to fit in the stock space. At least I hope it is, and I didn't just support terrorism.

lol thats the one i'm using right now...honestly i didnt notice any difference, it neva made it thru the day

I noticed ion the pic of that battery it is labelled li-on polymer which would make a difference if true. Li-on polymer > li-on.

I also be waiting for results of these batteries.
Thank you in advanced.

Thanks for the link smoothmouse.. I just read all the posts on the links you provided, and to sum it all up this battery is garbage, basura, spazzatura, ordures, abfalle. Read the HTC Sensation thread in the link smoothmouse posted if you want to see for yourself, but if you want the quick answer: DON'T mess with this battery!
People who bought this for the Sensation noticed it drained quicker than stock; there is another guy on there claiming it fried his phone.

Im not saying these guys are lieing but ill say this it may well be user mistakes.
When you replace a battery on an android phone sometimes you need to reset battery stats or it will keep using the stats from the previous battery and will appear as tho the battery is draining faster, as for it exploding any lithium battery can do this but its 1 in every million batterys made.
I am a bit suspicious of why there is chinese writing on the front since its unlikely to be shiped from japan to china any thing chinese should be avoided at all costs but soon as i get a little extra cash im gonna get one of these because i bought one for my htc dream a while back and it worked without any problems so maybe im just not an idiot and remember to do simple thing like resetting battery stats or just got lucky and got a good one from the production line.

Wrap something up in a pretty gold package, say its BIGGER, BETTER, FASTER, GREATER and the suckers will come out the wood works dying to spend money on it knowing full well that its crap from the start. The human being is a strange animal indeed.

I found this battery that's the same size as the stock G2X battery but you can get up to 27 days use out of it on a single charge. It charges from zero to full in 79 seconds! It powered the International Space Station for the last 74 years - On A Single Charge OMG!!! Its solar powered. Nuclear powered. Has a built in windmill turbine! Dead car battery? Hook this sucker up and you won't need gas for a year!!! All On One 79 Second Charge! It floats, flies, can suck a golf ball through 20 feet of garden hose! Its the chef of the future here today! All this for the low unbelievable price of $3.99 - SHIPPED!!! That's not all!!! Order in the next 43 years and we'll DOUBLE your order!!! For Free!!! That's Right!!! TWO Batteries of the future for the low unbelievable price of $3.99!!!!

MPJ 4300mAh extended battery mini review

Picked up this MPJ out off their website for $17.99 because I CANNOT find it on Amazon.
WHERE I BUY
A backup battery means a lot to me as my Galaxy S5 is running many apps, even though battery life on this phone is already an impressive part. Just received mine with a small bag, unwrapped and put it in. It seems a little larger than stock battery, ensuring a snug fit.
The 2800mAh to 4300mAh bump isn’t there for sure but there is still some increase. I’ll update soon after 2-3 times charging cycles.

After I fully charged it 3 times, it seemed to do great. This is my moderate to quite heavily day yesterday. With almost same usages (no auto brightness, average web browsing, bunch of streaming videos, texting, calling and etc.), stock downs to 20-30% by the time I went to bed and the new battery I'm at about 45%.
EDIT: Do not expect seeing any dramatic changes. Normally improving 10-15%, and there are several times, depending on my usages, where it up to 15%-20%.
6+ hrs on screen is my best by far and this is including 4-5 hrs of idle and light/moderate using, and only 1-2 hrs of heavy browsing, texting, etc. Have been also skeptical and hesitated about whether to pick up this without many reviews but on second thought, I can be the first and share my experience if that’s a real good. YMMV, I am not thinking about if they are spending money on promoting the well-knowness for their company, as far as I can tell, it is working fine on MY GS5.

It shouldn't seeing how it can use the original back.
I also to would like to see the stats on this baby because of the no extra bulk.

where did you get it?

I was about to post about this same battery! I ordered it on Amazon for about $5. I hope it is better than the stock battery! Here's a link if interested.

Interested to see how this battery works For long term use. Wonder if it effects the phone any?

Oh sweet, Thank you! =)

These batteries don't hold quite the charge the OEM batteries do, but it'll last a good 8 hours. I ordered a pair of these batteries and I'll see how long they last (Hyperion batteries have a good track record with my phones).

Nope, so I bought 3 of them. at 6 dollars a piece, and no shipping, even if i get one thats semi-decent it's better than no spare are all and I was making my way through a battery and a half per day on my S4.
*UPDATE*
4300 mHa Battery
I'm a very heavy user of my smartphone. When i had my Galaxy S4 i was going through a battery and a half per day. When i saw these batteries i thought i'd give them a try. I though 6 bucks, each, bought 3 of them for the hell of it. So in the old phrase of you get what you pay for is absolutely true in this case.
These batteries even say "Long Lasting High Capacity Li-ion battery" and are a 4300mAh battery, where the stock is 2800mAh. So in theory these batteries are 45% bigger than stock and should give me relatively 45% more time in operation of my smartphone on a single charge.
What it has given me is a great deal less. My S5 on the OEM battery would last from when i unplugged it at 6am to usually 5:30 or 6 at night before I hit the 30% alert. I just checked and my phone is currently 4H 50M 06S in and I am down to 38%. This battery as it sits is a complete waste of money.
Now as they were only 6 bucks each I did buy 3 so I will try the other two over the next couple days but if they are the same, then my suggestion is do not buy this product.

I just went with this one. Guess we'll see. I'll update a couple weeks after it gets here. http://www.amazon.com/gp/product/B00JIL7C5S/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

Makes sense, yes After all, no matter how advanced the phone is: the more advanced, the more battery eats.

Hum... I don't know if this battery i sreally a 4300mah...
Someone test the battery recently ?

I'm using this "brand" ( well, these printed labels ) since the S1 series.
They may not be the full 3800Mah capacity, but they always give me a full day of operation ( depending on the use offcourse )
I'm not able to test the capacity-claims ( because I don't know how )
All I know is the length of operation.
On the S2 and Note1 the power was slightly smaller, my order is coming in a few days
Will report back

I can't wait for ZeroLemon to release theirs. It was worth every millimeter of extra hugeness on my S4.

Mugen 6640 mah extended battery review Galaxy Note 4 with pictures and screenshots

Hey everyone, this is my review of the Mugen Power 6640 mah extended battery that fits the Samsung Galaxy Note 4
Here is the packaging contents, the battery itself, with the charging instructions and of course the required back cover for the larger battery

The battery came nicely wrapped and sealed in plastic to keep in clean/dry
The battery arrived with 3.86v, enough to make it all day through an 8 hour shift at work before i came home and killed it all the way and gave it it's first full charge
Here are the included charging instructions, which recommend a 5 hour charge even if the battery shows full before hand. Always try to use an OEM charger or quality aftermarket if possible, this is a lot of battery to fill without a 2.1 amp or higher charger, the included OEM Adaptive fast charger is great with this thing.
Here is the included card back in the package that has some information on it.
Here is a shot of the battery and back cover next to a AA battery for size reference.
Here is a shot of the contacts, just as nice as oem or even better, the battery itself is wrapped nicely too.
Here is the weight of the Mugen battery by itself
Compare that to the OEM battery and you can easily see that double the capacity is over double the weight!
Here is the Mugen Battery + Mugen back cover by itself
Now compare that to the OEM Samsung battery and the cover alone, the oem back cover only weighs 11 grams
Here is how much my stock Note 4 weighs with the OEM battery/cover and of course it has a Zagg glass on it too.
Here is the weight with the mugen battery/mugen back cover, one hefty beast!
Add my Hyperion case to the Mugen setup, which adds another 26 grams and you are at a whopping 10 ounces total!
Okay Now to the pictures of the full setup!
The Mugen battery door comes with its own built in kickstand, which works very nice for horizontal screen viewing. Note; it will not vertical stand due to the balance of the setup
The Mugen back cover fits very nice and snug all the way around the phone just like the OEM door
side shot of the fitment, great!
Of course it also comes with an included wireless charging mat if you already have a dock
Here we can see the extra thickness of the battery against the phone
Another shot of the battery in the phone
Here is the case i am currently using with the mugen battery, its a Hyperion honeycomb TPU, as far as i know it's the only case that will fit that you can buy by itself for about $5-10 on amazon
Since this isn't "made" for this battery, some of the cutouts are better than others.
The bottom cutouts don't line up well, one of the bottom mics appear to be completely covered, the other is all the way at the top of the cutout, the battery charging port is a tight fit with some cables, but i just had to stretch it before i put it on there. No one had any issues hearing me on the phone even though the mic port is off. The S pen cutout is fine.
The volume rocker cutout is a little to one side, but works fine, no issues there
The headphone jack is a tight fit for some , the IR blaster is all the way to one side but not worked,it works fine when i tried it, the same with the top mic port, it's all the way to one side, but not covered.
IF you look all the way to the left of this pic, you can see where the case already paid for itself with a fall from my pocket onto a smooth concrete floor. I highly recommend this case, since you want "SOME" protection with your phone.
Okay enough with these pictures, but what about the performance!?
Well the Mugen battery is rated at 6640 mah vs the stock 3320 mah, so it's rated at double the capacity...But does it perform as advertised? YES, in my usage, it gave me double the time i had on my stock battery. It lasts so long i haven't even got to fully kill the thing on it's own yet, but with the help of stability test app i was!
The battery behaves very similar to the stock battery, except for one weird quirk, when the Mugen battery hits 1%, it will last for another 3 hours of full brightness on the stability test app using full CPU+GPU Usage. Basically the stock battery meter doesn't know how to handle the difference in capacity, so the percentage is going to drop faster than the actual capacity should be, this is an issue with the phone itself not the battery.
Here are the screenshots all from 1 day of testing it. Basically i ran it without power saver and max brightness all day when i was at work, then i got home and ran stability test on max brightness to see how far it would go.
You can see i got over 7 hours of screen on max brightness time with the extended battery, these results would be even better if you had a better signal through the day. You can see during the day my signal at work is poor draining the battery even faster. If i use power saver with restrict background data on automatic screen brightness, i can do 3 days without charging.
Basically you get double the run time of the stock battery, which is very nice, since with moderate use an entire day can sometimes be difficult without charging a little bit. Now i can just leave it on without power saver, on a high screen brightness, and use it as much as i want, never actually get it very low throughout the day and charge it once per day and forget about it! I typically have "50%" on the battery meter by the end of a 12 hour day if that means anything to anyone.
The phone will shut off only when the battery reachs <3.40v, which like i said before was 3 full hours of stability test after the phone reached 1%.
Overall i highly recommend this product, it's just what anyone needs to use their Note 4 to it's fullest potential, and never have to worry about the battery dying in a single day.
You can purchase the product here if you like it.

Took the letters right off of my keyboard! lol

Great review. Nice and helpful. Far to thick for my tastes.

I've really gotten used to the weight. It's so worth it to not have to stress about battery life. The hyperion case helps it slide right into and out of the pocket also.

I just might have to take this into consideration, since I'm considering another battery.

Honestly this is one of the best & most detailed review I've seen! Thanks!! I wasn't really in the market for a extended battery due to size, but your review made it a definite sale!

If you get it you will really enjoy the battery life. It's literally like having a double capacity oem battery. It's so cool to be able to utilize my Note 4 however i want without using power saver and never have to worry about the battery dying if i charge it every night while i sleep.
Also if anyone needs a good charger, i got a really nice charger off amazon for a bargain, but looks like it's not available now.

This thing charges just as fast as my oem Samsung quick charge 2.0 charger and doesn't even get warm to the touch. really surprised by the quality/$$ ratio.

Trying this weird M-COM brand Battery, Claims to have 5000 mAH

So, I just bought this battery
Probably you guys haven't seen brand like this before
M-COM (Claims to be 5000 mAH in capacity)
Surprisingly this battery have temperature sensor.
I see lot of you guys having problem with battery replacement with built in temperature sensor in other thread.
Bought it for IDR 90.000 (6,5 USD) from local online shop.

Well here goes nothing.
I crack open my angler and recognizes that this battery cable is shorter about 1mm, but it's a no problem for me, just pull a little bit force an viola.
(btw metrics are different here)
It booted up so I try downloading Accu Battery app.
Been using this battery for 3 hours for now, I charge this fella up for a little time and got 4% for 140-160 mAH
Here is my rough calculation
Estimated real battery capacity
3800-4300 mAH instead 5000 mAH
I'll keep you guys updated when Accu Battery done it's job

Any update?

Turns out pretty legit.
Currently showing 3100 mAH
With 4-5 hour SoT (mostly watching youtube)

You mind posting a part number? It's about that time on mine, and this seems as good an option as any.

I don't think it have one, i looked both battery and package only seeing plain and branding, sorry.
There's barcode actually (8547182249565)
I heard that barcode are unique to a product but, i couldn't find its use (google won't show anything) rather than pointlessly scanning at them.

That's about right. Thanks for looking.

Hi just curious to know how is it going?

No added thickness? how is it performing?

No thickness added, performs good.
No issue at all. except I forgot to mention that the unit is a bit shorter, enough to make a wiggle inside if you don't stick an adhesive in there so i wedge a folded paper at the bottom of battery slot to keep the battery in place.

It's good, now showing stable 3200 mAh.

You swapped the battery out yourself, I'm guessing?

How difficult is it to do yourself? I heard its easy to crack the camera lens and break a few other parts while doing this and not being an expert, would it be impossible for a first timer? Would I need any other special tools besides pry tool? My N6P battery experience has been terrible.

It is pretty easy to crack the camera lens, so it's highly recommended to buy a spare camera lens part in case the old one breaks. I'm going to be replacing both the battery AND the entire back metal frame soon. Here's a video that demonstrates how to replace both: https://www.youtube.com/watch?v=UetgEdh7mDc

I just replaced my battery and I would recommend getting an X-acto knife and a heat gun. The heat gun helps soften the glue to make it easier to remove everything and the X-acto knife I used to pry everything apart. It took me about 30 minutes to replace the battery.

Yeah a heat gun would make the disassembly much more easier. Luckily I work at this phone booth (for installing screen protectors) and we have a heat gun there. I'm probably gonna do the whole installation at my workplace, we don't get much customers anyways lol.

Hi, BTW this is my 1st post here
Could you please try testing with "Ampere"?
PlayStore: https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en_US
I've used both AccuBattery and Ampere. On my Nexus 6p with original OEM battery it displays:
Max Capaity: 3450 mAh
Estimate Life: 70%
Currently running:
Pixelboot's Lineage 17 with the 4 Core Boot image in hopes that disabling the "4 Big Cores" (ARM Cortex-A57) should help battery life but based on my testing it doesn't help and in fact seems that battery drains faster
TESTING:
Ampere - Power while Idle: min: -220 mA to max: -370 mA
Ampere - Power playing Video: min: -600 mA to max - 910 mA (Only 2 apps open)
Ampere - Power switching Apps: min: -600 mA to max - 1120 mA
To put in perspective,
Battery loss down 1% for every 1 minute
Undoubtedly I need to replace my battery

With all those extra things to buy I'm not sure its worth it at this point as the phone with working parts can be found for $100-150 these days, I'll probably put any cash I've saved twords a future model and leave this as a sort of tablet use with a charge cable handy.

Um well that's basically what my 6P is lol. It's a used 6P that I bought for $90, and am looking to replace its faulty battery and damaged back. In fact, I just did the replacement yesterday. The parts required is not a big deal, it's the disassembly that's a huge pain.
The camera visor and plastic bottom were fairly easy to remove with the heat gun, but the metal cover took a fair bit of struggle to get it off, and in the end it damaged a bit of the display's plastic rim. The hardest part was removing the battery, which was absolutely hell. The battery adhesive is literally glued shut onto the frame, and it takes a lot of force and pressure to get it out. And the dilemma is that if you use too much force, you are risking of puncturing the battery, which I unfortunately did. Waited till next day for the battery to cool down (from the puncture) and I slowly managed to removed it by using plastic gift cards instead of the metal wedge tool that I used before.
Was a tricky experience, but in the end it worked out.

Glad it worked out. I'm terrible with handling these type of tiny electronic components I know I would surely break it heheh.
Be interesting to track your new battery with something like AccuBattery and see if it infact keeps its rated capacity over time. I noticed some bad after market batteries look like there performing well at first and then suddenly the maximum capacity starts dramatically falling after each charge cycle.
