Hey guys! So i posted smth abt Bloated Battery and u guys told me to change it. Surfing the net when i came across this online shop that sells 2480mAh Battery for the Galaxy W (and others) and i wonder whether its real cos' i dont think such small slim battery can that much mAh rite? But also, its made in Japan NOT China so i expect to see "quality" here
check the one in my signature, it's exactly the same
i cannot compare it with stock one because stock one behaves badly after some overheats and experiments
everything is chinese but mine imho is quite nice, got 340 antutu battery score with it
the screenshot in sig is also made using it

So it means, the mAh on the "Gold" one is exactly the same (1500) but behaves somewhat more better than stock?
Sent from my GT-S6500 using xda app-developers app
don't have any equipment to exactly measure the mAh, possibly it's about stock one
feels nice to replace damaged stock one but seems not to be a variant for super upgrade
haven't you seen anyone post antutu battery score here to compare?
or any method to measure the stats?
PS overall i'm satisfied, it's worth it's 7$

This is the ultracheap golden one I was talking about in the other threat where you asked about freezing your bloated battery.. Having here 2. Each for 5 Euro.
So well. This batteries never ever do have this capacity. Somwhere around stock capacity or a bit less. They do not last that long like a Samsungs battery, so you will have to reacharge it a bit more often than a new Samsung battery. It´s even a bit thinner than a regular 1500mA battery.
However there is one advantage in using it. It´s a LI-Polymer battery. Not a Li-Ion battery. So it doesn´t use an fluid but a polymer and therefore the risks to get it bloated are much less than with a LI-Ion battery. I ran them also really hot and they didn´t get bloated so far.
When this battery would have about the same thickness like the Stock Samsung battery it really would offer more capacity but thus it´s thinner it has just about the same or a bit less and the 2480mAh are just fake.
So well you can use it as an replacement. Just don´t expect it to last longer than a stock battery.

Wait, Li-Polymer? I went researching and they said tht its the most dangerous battery in the world. They say tht its more likely to explode if u overcharge. I don't exactly know whether it true or not but u shld try search on YT abt it...

That´s nonsense. The polymer is a static foil which can´t boil and create gases like the fluid in LI-Ion batteries. Well you can make everything explode. Even a banana by sending a flash with thousands Ampere through it.

Many cellphone manucafturers already switched to Li-Polymer battries but those who don´t are still having legit contracts with LI-Ion battery manufacturers which they are forced to fullfill. This has nothing to with reality but with making bussiness and telling the customers what they want them to belife.

Sorry but there you are wrong.
The difference between them lies in the material used as the separator. Rather than an inert substance with holes covered in electrolyte, the separator is made of a micro-porous polymer covered in an electrolytic gel that also serves as a catalyst that reduces the energy barrier in the chemical reaction between cathode and anode. Therefore, Li-Polymer batteries allow for a slight increase in energy density.

http://www.buchmann.ca/article6-page1.asp
Risks and limitations on li-polymer battery:
1) Overcharging a Li-poly battery can cause an explosion or fire.
2) During discharge on load, the load has to be removed as soon as the voltage drops below approximately 3.0 V per cell (used in a series combination), or else the battery will subsequently no longer accept a full charge and may experience problems holding voltage under load. Li-poly batteries can be protected by circuitry that prevents over-charge and deep-discharge.
3) Compared to the lithium-ion battery, Li-poly is less advantageous in terms of life cycle degradation rate.
4) Lithium polymer-specific chargers are required in order to avoid fire and explosion.
5) Explosions can also occur if the battery is short-circuited, as tremendous current passes through the cell in an instant. Radio-control enthusiasts take special precautions to ensure their battery leads are properly connected and insulated. Furthermore fires can occur if the cell or pack is punctured.
6) While charging the lithium polymer batteries, the individual cells in the pack should be charged evenly. For this purpose, the cells are to be charged with special chargers. This entails special care while charging the batteries in addition to incurring expenses on procuring the chargers specific to lithium polymer batteries.

it is too cheap compare to oem battery, so dont expect goods specs be accordance to wat it advertised.
it cant be li-polymer battery, too expensive to manufacture.
2480mAh?? do a search buyers claim it to be below 1200mAh.
google search the 2900mAh battery, thickness is double, this is many claim to be the true deal.
china have many rejection parts from corporation companies, their sub-contractors to sub-sub contractors to sub-sub-sub small companies.
many will recycle to gain back some of their loss $$$ on rejections instead of dispose/destroy those parts.

Oh wehhh. All the disadvanteges you are listing up in your previous post are also related to LI-Ion and every other battery.
Like I already said. Overcharging a banana with a flash will make it also explode. A flash hitting your head will also overcharge you. It can make your eyes explode and will boil your blood imediatelly. Why do you think they are bounding the eyes for people who are getting killed on electrical chairs? Because their eyes are exploding when the current is streaming through their body.
The same to short circuit a battery. Even a silly carbon battery will explode under this circumstates. That´s also why most batteries used for phones are having a short circuit protection. Even the old NiCd batteries which were used in the stone old cellphones.
About droping below 3V. This is legit for both. LI-Polymer and LI-Ion. Not only to LI-Polymer.
LI-Polymer batteries are charged the same way like LI-Ion batteries. The source telling it needs an special charger is a guy who is just sharing his opinion without referring to fundamental sources.
The other source is from 2001 and rather outdated when it comes to density but even there the guy says it´s less dangerous to catch fire.
To sum this up it seems like you just are collecting contrary claims like the guy in your first source without being objective just to make this type of battery to appear worse compared to the older LI-Ion batteries. But not telling the full truth to make it appear like LI-Polymer can explode when overcharged but LI-Ion can not. And this is for me bending the truth.
And to be exact. Not Li-Ion battieries began in 1912 but simple non rechargable Lithium batteries like the one used in watches. Rechargable LI-Ion batteries began in the 70´s and Li-Polymer is the further developement of LI-Ion batteries where newer manufacturing processes and developement make it even safer and having a higher density.
So last but not least. It IS a LI-Polymer battery. It has no hard case like Li-Ion batteries require to have to hold the fluid in it. You can bend this battery forth and back like all li-Polymer batteries. On the back side it even says it´s a Li-Polymer battery, but the missing hard case and the bending test are enough evidence for being one.
AND it has been said already many times it´s never ever 2400mAh but somwhere around stock capacity. The is just fake to get better sales.
However for this money there is nothing wrong in buying it as an replacement.

Could fry your phone as they state that you shouldn't use "inferior charger" lol. They'll blame your broken phone or battery on the charger.
And I bet it is no where near 2300mAh..... So many cheap batteries state they are, but in reality they are no where near the capacity they state.
I bought some cheap Chinese batteries knowing they woiuldn't be as good as the original battery even though they state 1800mAh. And guess what, they are not as high a capacity as the genuine battery, probably closer to 1000mAh of gut feeling. But they are only for emergency use because I do not trust them a lot so try to reduce the risk of them ruining my expensive phone, more for leaking or exploding rather than high voltages (because high voltage is not really possible with the chemical nature of batteries). And I never charge them in the phone in case they explode.
I have read that a lot of these batteries are in fact smaller generic batteries and all they do is put an external case on them to make them fit different phones. I wouldn't be surprised if the one you linked to is the same battery as mine but with a different sticker.
Hi,
Was wondering if anyone has tried one of these.....
Its 2430 (or 2450mah) the ebay page cant really decide, im guessing its a typo.... Its the same size as the default battery. Thats a calculated 47% increase in battery capacity...
Link here:
http://www.ebay.com.au/itm/110750637282?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
Its the biggest battery capacity i can find without increasing the physical size of the battery and requiring a new case....
If not, i will post some of my own reviews once it comes through.

Ya i'll bet its a typo, more like 1450mah rather than 2450mah. No cheap aftermarket battery can even match the stock battery in capacity let alone offer 50% more capcity.
im not expecting a full 2400mah out of it, more like a 2100mah....
thing people need to realize, is the stock battery is made in the same places (sometimes) as these after market batteries. The quality might be slightly off, but not substancially..... they are all made in asian countries for less than $0.20 a piece in mass production....

You'll be lucky if it even matches the stock battery, you just can't magically cram more capacity into a battery. The samsung 2000mah battery is thicker and comes with a new cover, why isn't samsung using this battery if it has more capacity and is smaller than its own 2000mah battery? If its too good to be true(on ebay) it probably is.
probably the same reason why they dont release ICS 4.0 and other things straight away that other phones have that is better than what they currently have..... coz they are slightly retarded as a company lol
not a chance that has more power than the stock battery if its the same size. Those gold wrapped batteries from ebay always get really bad reviews. Youll probably find its 1300mah
Seen one review where it was a smaller battery in a plastic frame. Battery capacity was much lower than the stock battery. If it sounds too good to be true and it is cheap, then it probably is.

...are you serious? it's a proven fact that non-OEM/aftermarket batteries in general are usually worse than stock batteries. check out sites like http://batteryboss.org/ you can see testing of aftermarket brands like seidio and mugen...the actual capacity is between 55% to 85% of the advertised capacity, while OEM batteries are ~95%+.
as for what you said about samsung being a retarded company and not releasing the best hardware/software possible, you'd rather trust a random ebay seller with an UNBRANDED battery coming straight from china for $14 aus dollars, which is somehow still 47% higher in capacity, over a multinational corporation with trusted suppliers who are industry leaders in their own right? you really think samsung would willingly reduce their battery capacity in light of the huge implications it could have on the sales of their flagship phone?
as a final piece of evidence, here's a google translated website showing the testing of so called ebay '2430 mah' batteries. http://translate.google.com/transla...e/samsung-galaxy-s-ii-2-3500-mah-2430mah.html as he shows halfway down the page, the real capacity is somewhere between 1000-1250mah. terrible. you should research more before you blindly advocate for your misinformed purchases. all it does is drag other gullible members of this forum down with you.

Different material can make a big difference.
I know it's probably bull****, but i bought one of those battery and i was impressed by the time it last. I tought i would end with a smaller time than stock battery, but it lasted longer. I did not made super precise test, I don't have time for that. I must always be with latest rom / kernel so flashing a new rom or kernel a day don't let me much time to bench battery xD. My point is, that i think it last longer than original samsung battery and this, even if people are doing test that proof i'm false.
Guys you're all being very unfair.
This is obviously a Global Dynamics battery, I believe the model is 'Fringe'. It actually draws it's extra power from a trans dimensional link and was invented by Dr William 'Pointy' Bell.
I'd suggest everyone buy one.
The next version includes the facility to phone yourself after the final race of the day and tell yourself the result before it happened.

So this means the advertised battery should have a capacity between 1336.5 and 2065.5. So one could be lucky and really get a battery with more capacity than the stock one.
Sure, I agree with you that such cheap battery can't hold that much juice. However for a spare battery it is fine if you look at capacity/price.

Typo is an abbreviation of 'Typographic Error' and the phrase originates from when newspapers were printed using printing plates as against computers that are used today.
An example of a typo would be writing h3llo rather then hello or 1243 rather then 1234, it's usually a mistyped character instead of a spelling mistake.
Hope this clears it up for you.

True, but I also did mention that another site tested the capacity specifically for the ebay '2430mah' batteries, and came out with a total capacity of 1000-1250mah. Even if we take it as 1250mah, that's still a 25% decrease from the stock capacity of 1680mah, which is abysmal. You could argue that it's fine as a spare battery, but at that price and capacity you might as well just buy another stock OEM battery, and save yourself the frustration. However, I would definitely argue against using it as your primary battery, for obvious reasons.
Any GOOD suggestions to a STOCK size battery with BIG capacity, that WORKS? Or battery similar or better than Samsung's 2000mah battery?
I use mostly clear TPU cases. Thinking of cutting hole in battery cover for a bigger battery too.
I wish battery covers like those in the 2000mah extended battery kit could be bought in colors, cheap. And then get some nice battery.
Sadly all those mah ratings can't be trusted

No such thing, its either the stock samsung battery or the larger 2000mah samsung battery, everything else is going to have lower capacity no matter what the label says.

Hey guys I just saw a 3500mAh battery for SGS2 on ebay. Is it safe to use such battery? I mean it won't harm the phone, will it? :O
Probably won't harm the phone, no.
I bought a 3500mAh obscurely branded Chinese battery in mid-December. Tried it out for almost two weeks, a bunch of charge/discharge cycles & estimated its real capacity was around 1900mAh. It also used to heat up a lot on recharge (mid-high 40's Celsius, which isn't normal when the phone isn't being used whilst charging).
I took it back, got a refund & bought an original Samsung 2000mAh battery. Hasn't missed a beat, is obviously close to its advertised capacity given I get around 20% more use out of a charge than I do with a 1600mAh battery.
Obviously your mileage may vary if you buy one of these (you might have a better experience than I did), just thought I'd let you know about my experience.

with the 3500mah i am getting 60H of usage... so my 3500 is truly 3500mah!
the language is hebrew.
i use congnition rom 1.51 and siyah kernel.
So, where can I see a trustful review on batteries for SGS2? What is the most extended one?
It's really frustrating that my current stock battery is only enough for 2 hd video view (4-5 hours).
Also, the higher the mAh value the more battery lifetime is, right?
I would really want to buy 3500 mAh, but it costs so little.
And the official Samsung variant that offers the longest lifetime of a battery for SGS2 is this one, maybe Mugen 3500 mAh is the best choice out there?

What is the model name of the battery? Is it being overheated in comparison to stock one?
why should it overheat?
it is lithium ... same same
Yes, it's special lithium from China extracted under full moon and blessed by a thousand virgins
Really now, if it was possible to manufacture a battery having more than double the capacity of the stock battery while taking up the same volume, don't you think the megacorporate Samsung would buy that technology immediately in order to use it themselves ? "Too cheap to be true" is valid even here; most knock-off batteries either are fake ("9999 mAH SUPER EXTRA" sticker over the original rating), or will degrade quickly in time leaving you with a dud.
Since there are already fake electronic components...
... why not fake and cheap batteries too, certainly seems to be a high demand for them.
a. it is not the same volume! in is twice as much as the original.
b. the i9100 has a circuit that allows a slow stable charge rate so i dont think it will damage the battery.
As well as being made of inferior materials, not being subjected to the same QC, not having the fuel gauge chip present in original Samsung batteries, you pretty much get what you pay for.
My advice would be to avoid non-original batteries altogether, and given a 2000mAh original battery will cost around the same as one of these 3000mAh+ batteries with all their problems & poor life, it's a no brainer.
Stick with Samsung batteries.
fuel gauge chip?
i would like to see that chip in an any cellphone battery please.
If you're not aware of/don't know about the fuel gauge chip in original SGS2 batteries, you've probably been living under a rock since the phone was released

well i think that you misunderstood the meaning fuel gauge.
there is no chip in the battery that is in charge of the fuel gauge.
furthermore there is no use of recalibrating the battery in out i9100 model.
all you gave me is a link you Google...
please... show me that chip! i would like to learn something new about lithium batteries..
Plz can you Possible link topic of the battery

What about the other question that you chose to ignore, regarding the battery's model that you mentioned.
thanks for the info guys,
cuz I need a battery really disparately cuz I use so much data and sync :'(
I couldn't find something really reliable feedback from viewers, and i'm trying to find something with good quality as well!
guess i have to search further!

Saw this aftermarket 6000mah battery for the 20X on aliexpress, good reviews all round (one review says it's 7500mah). Has anyone tried this? If so how was the installation process?
5000mah already lasts me 2-4 days but 6000mah would be really handy during heavy use days.

Is the battery bigger or thicker than orig ? u cannot make bigger mAh and keeping same size man think.com ...
download an app which detects battery capacity and let me know who was right ...
Or let me know how longer will phone last from charge than with original
Edit : I attached picture from your link and they claiming in description ''above 5000mAh'' How can you be so naive??
And 7000 ?? yeah right ... keep dreaming..
And one Russian (with bad english) left only 3 stars s the battery apparently is not any good .. Didn't understand quite what he was saying.. But 3 stars says it all
to be fair its not all just about size, there is a thing such as energy density, which is actually the most important factor in a battery's design
in general, i would advise caution when buying non-original batteries. at the same time, higher capacity in the same form factor is totally inside the realm of possibility.

As I know about batteries. Li-ion batteries has best density
Speaking of cell density batteries there would have to be new design and new technology.
For more battery cells you obviously need larger battery ! THAT'S WHY Mate 20 X / Honor Note 10 battery is the largest from all.
Battery Size
Although higher-capacity batteries generally last longer than lower-capacity ones, they are not always suitable for use in every device. To achieve a higher capacity, battery makers often have to fit more cells into each battery. Cells are the parts of a battery in which the chemical reaction needed to generate electricity happens. Increasing a battery's cell count can in turn increase both the size and weight of the battery, making it unsuitable for use in slimline devices such as smaller cell phones and netbooks. The temperature and speed of electrical current discharge affects the overall capacity of the battery. Poorly made batteries often heat up too quickly resulting in performance issues or degraded capacity.
To calculate a battery's life, divide the capacity of the battery by the current required by the object it powers. For example, imagine that you have two batteries for your cell phone, one with a capacity of 1000 mAh and one with a capacity of 2000 mAh, and that your phone requires a current of 200 mA to function. The first battery would power the phone for five hours, as 1000 divided by 200 equals five. But the second battery would power the phone for ten hours, as it has double the capacity of the first. While a larger number indicates battery power, larger mAh batteries may not be better if it is a poor quality battery. It simply means it can store more power.
Cell phone battery life is heavily dependent on the way in which you use the phone. The more features you run at the same time on your phone, the more current your phone requires and the quicker the battery's capacity drains. This is why using WiFi or running complex games on your phone drains the battery quickly. As such, a battery with a high capacity that is used to power a smartphone might last for less time than a low-capacity battery that powers a basic device.

That's far from accurate. There are phones with 6000 even 18,000 mah capacities. For example the Samsung Galaxy M31 has 6000 mah.
Mah numbers stated on batteries are just that, numbers. There are phones with even lower battery capacities that outlast higher battery capacity phones by several hours including the 20x as yt video showdowns between different phones demonstrate. No doubt, although a higher mah indicates greater battery life generally, relatively speaking, battery life overall depends more on what's determined by the interaction among software, voltage and hardware than what's stated on the battery.
It's not just a drop in mAh's that warrant replacement. If there's any detected battery swelling the battery needs replaced asap.
The risk of a thermal runaway event increases dramatically with a damaged (swollen) Li battery.
This can happen even with a new battery.
The swelling can possibly damage the phone as well, without going supernova, by putting pressure on surrounding components... like the display.

Your dropped battery capacity isn't surprising but natural during the course of its use. My own battery has a capacity of just shy of 4700, somewhere in the neighborhood of 4630 last time I checked.
As you stated, your battery was at one point at a full 5000 mah and lost 10% of its capacity to what's presently 4500. But just so you know, your battery is not precisely filled to 5000 mah right out the factory. In reality its always less than whats stated; the reason being is that batteries differ in capacity during manufacturing mostly to cut costs. Battery manufacturers round the numbers to the nearest hundredth or thousandth to read batteries easier. Hope this helps.

Correct. This is why within the battery, cells are damaged which skip proper readings by the amount equal to the amount of juice generated by the lost, damaged cell.

This is what a typical Li polymer battery used in cell phones looks like.
There's no hard case to contain it so any internal pressure immediately becomes an issue.
Swelling in the cell it's self will distort the structure of the cell and alter it permanently.
A sealed plastic bag surrounds it to hold any vented gases or goo.
It's just one cell and it's rolled construction is similar to a capacitor.
It's alarmingly flimsy... and packed with energy.

You're right about the waterproofing, don't test it.
It might work...
In my case it wasn't abused and I was lucky it didn't take out my Note 10+'s display.
Heat and/or rapid discharging can cause it.
Or a bad copy from the factory.
Or simply accumulative damage over time and insults. I live in the desert so heat is omnipresent. I try to keep it cool especially when charging.
My phone has never been cold charged or even close to damp. Cold charging (>40°F) can trigger a run away thermal event or cause permanent damage.
Charging in temperatures under 72°F can cause Li plating which permanently degrades the cell.

Youre not bright when it comes to the subject of battery and 1000% wrong yet again. The Samsung Galaxy M31 is korean which you mistakingly think is chinese and has a 6000 mah battery which I'm sure youre too afraid to verify in google. The Helio P70 has a 18000 mah battery which of course you deny since you dont operate in our reality.
Longer capacity batteries dont guarantee a longer lasting life than lower capacity ones. Case in point, the iphone xr with 2940 mah equals the note 9 with 4000 mah as this yt video proves:
Youre trying hard to be relevant by trying to edge out people's comments with your nonsense. Being negative and insulting others violate forum rules which doesnt win you friends here. I reported you to the mods btw. Guys like you dont last long here. Be educated before you look foolish again.

As you see they are somewhat fragile. I inadvertently ripped right into the active layer before I knew it after I removed the outer bag
Crazy. A fruity smelling solvent was also present. I wiped down my hands even though I sensed nothing; caustic burns are the worst.
It's a good idea to have little charge on these when >gently< removing them.
I'm not as comfortable with these packs as I was before, ignorance is bliss... until it starts smoking.
