afaik li-poly battery have a higher durability than li-ion.. just wondering, does S2 have this kind of battery?
Or is there any reason why samsung uses li-ion instead?

li poly batteries are very difficult to maintain unless the charging system has been setup for them. li poly batteries can explode if over charged and they go off liek napalm and keep burning till nothing is left.
One question;
I have two batteries for my GNex. The original one and a 2300mAh extended one. If I calibrate my battery for the original does that mean I have to recalibrate if I use the extended one? I tend to use a little bit of both depends how much I use it a day, so I can get through the day without charging.

Doesn't matter. There are dozens of pages of debate on the battery calibration front, but official word from Google is that things like wiping battery stats is useless. And most electronics/battery knowledgeable people say that battery calibration is not useful in modern lithium ion batteries.

Hi,
I am looked several hours for a response to my question, but have not found any answers. I have recently bought a Samsung Galaxy S3 and I am looking for a higher capacity battery, but one that is the same size as the original. I am not looking for the extended batteries that have new backs that come with the sale. The battery should be able to slide right into the phone and attach the original cover. I am perfectly alright with spending a decent amount of money for the improved battery.
Thanks.
Unless someone can prove me wrong, I think all of those listings with higher mah are bs. You're best with just buying a few OEM Samsung batteries. You can also buy the external charger(+phone dock) from Samsung, or a 3rd party one from ebay (charging on ebay one is extremely slow)
i am testing the hyperion battery 4000mah right now, final verdict will be on saturday. doing the charging as per instruction.
Yeah bigger battery but fits under the same back is a myth. Mugen claims to have a 2300 but I am not sure if it is for real.

they have quality battery in the past. i own 2-3 of their battery and you get what you pay for.
yea the only way would be able to is if they make some modified Chemical for their Cells.
Or (more likely) they just dont follow the same expansion tolerances that OEM manufactures do so they can cram fatter Cells with slightly higher capacity into the same opening in the phone back.
I wouldn't just dimiss the Mugen battery, they're the only one so far that has 3.8v spec on their batt, which from little research is different chem from 3.7v.
And if the phone is regulating the charge, then charging these 3rd party 3.7v batteries with our built in charger will kill these batteries in a hurry.
without NFC and less regulated (less safer) packaging i can see extra 200mAh possible. but not worth $45 IMO>

Are there any differences between how the phone charge and how these 3rd party devices charge? Won't they all stop when the batteries reach 4.2v? The HTC rezound comes with either a 3.7v or 3.8v battery and I've not seen any indication that swapping batteries is a problem.
I've seen a similar subject for other phones but not for the GNex. I bought some OEM batteries off eBay and turns out they're fake... not only does the NFC not work but they also put out 3.8 volts where the real battery puts out 3.7... Does anyone know if this is safe to use. I really don't want to jack up my phone from using a bogus battery.
With other phones it seems that the main problem is the battery will not charge fully unless charged in the dock. I've used the battery long enough to check the voltage and if the NFC worked then took it out.

I'm not sure about the gnex specifically. I have an extended battery in my G2 and on "battery widget" it says it's 4.19V, on the battery the label reads 3.7VDC. It is a ebay china battery. I can't say if the widget is accurate or not, but I haven't had any issues on my phone.
Lithium batteries fully charge around 4.2v, 3.7-3.8v is for storing the battery long term. Since at that voltage there isn't much stress on the cells.
Thanks for the info. I'll just have to assume since the guy has sold quite a few of these china batteries that none have blown up yet or else it would have been reported on eBay.

I am using the extended battery and nothing wrong with it haven't had any problems yet and its been 4 months

ok guys you can laugh as much as you want but i did it lol . i used to have the nexus that google used to sell which was a great phone i had 2 backup batteries for the phone . i was looking at my note two and note 3 and was looking at the difference in battery in each one and found a way to run the nexus battery on the note 2 and the note 3 lol it looks ghetto but works and i never have to run to charger. look at the pics
you can see the size difference in the battery size is major but the battery for the nexus does last pretty damn good for some reason. on the nexus battery on the side where the metal connections are i shaved off the tabs on that side look at pics lol
R.I.P batteries or Note 3. :| Lol.

Well the battery from the nexus was just sitting in my desk not being used being that ibsold the nexus . So I was like wait will this work in my note 2 and 3 it did. Very little mods needed yo be done other then shaving a peace of wood or plastic to hold the battery in place and shaving the tabs on one side off so it would sit flush against the pins .

It might run okay for now, but in the end you'll blow up the battery and make the phone unstable. The GN3 battery is 3.8V while the GNex battery is 3.7V. Yes, that 0.1V makes a difference - the phone will charge the GNex battery with a too high voltage which can cause it to overheat and swell. The phone running off 3.7V will be underpowered and might or might not randomly crash.
This thread scares me....

It's not that big of a deal. Lithium batteries have an upper limit of 4.2 Volts which is why if you use a general purpose charger such as those used for charging RC packs you can charge Li-Ion and Li-Po batteries both on the same setting. Either way it charges them up to 4.2V and then cuts off. Once a load is applied, the battery drops to its nominal voltage - 3.7 or 3.8V and remains at that level for most of its life before rapidly dropping off when it gets low. When this happens cut-off circuitry kicks in around 3.2V or so to prevent the battery from discharging too much which will permanently damage it. Since the battery can't be safely charged above 4.2 or let drop below 3.2 or so, all the charging and discharging is managed by a chip designed for that purpose. Also, it means that you can't overcharge your battery by leaving your phone plugged in 24/7 as the charging chip will stop charging when it reaches that upper limit.

Lithium ion batteries with a nominal 3.7 voltage should be charged to 4.20 V or so.
Lithium ion batteries with a nominal 3.8 voltage are typically charged to 4.30 or 4.35 V. It's a new type of lithium ion battery with different chemistry, and hence the different voltages. If you take a battery meant to be charged to 4.20 V and repeatedly charge it to 4.35 V, its cycle life will be significantly reduced. 0.1 V difference will reduce the cycle life by something on the order of 50%. Here is a reference: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Apple, Samsung, and Motorola seem to be using this new type of battery, and the phones are charging them to 4.30 or 4.35 V. I'm not sure how widespread the technology is or if it has trickled into aftermarket battery offerings.
I commend you for your work and glad your getting more battery life with this mod but I'm sure most of us are fine with the life of the phone stock gives us without any modifications or just wait til zero lemon releases their behemoth 10k mah battery with zero shock case to protect the phone.

awesome. this means i will probably be able to stick 4pin samsung batteries in my note2. must be sure the 3 pins on the note2 correctly connect pos and neg with the plates on the 4-pin batteries. in a few years the note2 replacement batteries on ebay will have shorter lifespan due to storage in the warehouse. instead i may purchase a battery for a then current model (such as galaxy s6 battery) and stick that that in my note2.

But with this new 'smart battery' and 'smart charger' system it seems very likely that the battery's capabilities are read by the charger so that the charger will not cause damage. It might be that the charger will adjust the charging protocol if it can support the battery's needs, or perhaps refuse to charge an unsupported battery. I think if he measures the charging voltage he might find that it is different for the two batteries.

Thanks to this, I will have more battery life. Cheers! Just kidding!
