So apparently the Vibrant 4G will have a 1650mah battery
see: http://www.engadget.com/2011/02/02/t-mobile-promises-samsung-galaxy-s-4g-for-launch-this-month/
If it does will you be getting one for your Vibrant? (assuming it fits)
If I wanted to upgrade my battery (which I already have), I would get something actually significant (like 3000 MAH), instead of a 150 MAH increase.
If you follow this thread in the Captivate forums: http://forum.xda-developers.com/showthread.php?t=906611
you will see that extended batteries don't live up to their rated capacity. I think a real extra 150mah would make a fairly decent difference in life.
Yay! Armani battery is in the 4G. This means cheap batteries for us!
Nice.
I'm getting one. My original 1500mah is 6 months old now with daily or more charging. This will be good.

I have an extended battery (3000 MAH) and it has significantly improved my battery life.

But is it twice as good? On my stock battery I have managed to last 24 hours with normal phone use. good enough for me
Enjoy your brick phone lol

I tend to think that the Samsung original batteries perform better, and my reading on the topic seems to bear this out. As such, I'd be interested in such a battery, if it would fit my Vibrant. The small upgrade in power on paper would probably translate into better life than the small bump indicates. My Samsung battery lasts pretty long.

With normal use, I get about 1% drain an hour.
The battery doesn't even make the phone that big, and I happen to love its size. The vibrant feels far too thin for my large hands, and the 'brick' makes it fit perfectly (especially while in landscape).

Why not just buy an extended battery off Ebay for like $10 and try one out yourself? Based off personal experience, and the reviews from the Extended Battery Review thread, you will see just about everyone has much better battery life with the bigger batteries.
I really doubt you will get much more battery life with an increase of 150 MAH.

I second this notion!
I'm sitting here, 3:13 am, and my phone's been unplugged(And decently used for my habits) for almost 20 hours. I've got.. 28% left. The size is actually decent, and just a tad more heavy. For 14$ you really can't go wrong here.
i wouldn't update.
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.

I have one of those I got from DealExtreme and it is great. It lasts 2x longer than the original Samsung battery.
I take care not to swap them often, because I am afraid that this action might damage the original cover, eventually breaking it.
Battery Life
I am still using the 1650 mAh battery (stock) for my S2.
I am really facing some battery issues. Its charging almost all day !
Yes I am using 3G all day and WiFi HotSpot too. But use wifi at home. Thats when I get good battery life. Any better way to conserve some battery ?
Any tips might help
Thanks
Got mine a few days ago from eBay and its been fine so far. It last more than 2x the regular battery. Phone does not heat up or anything strange..
Sent from my GT-I9100 using XDA
well i an getting with the original battery 24H of usage.
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

I have just come across this interesting Poll on facebook concerning the replacement of internal batteries on HTC One Series with extended batteries.
https://www.facebook.com/questions/10150675611462172/
Apparently Mugen is planning to produce extended batteries for internal battery phones as well and supply an intrusion manual for users on how to open the phone and replace the internal battery.
What do you think??
Vote the Poll here or on facebook and we can discuss the issues in a meanwhile!!
since the cover non-removable i don't think that i would do it...
Would a extended battery case that would latch on the 5 pins at the back be more feasible instead? Seems like a less intrusive method of extending battery life.
On facebook 55 voters voted with yes - open yourself!! and like 7 voters in total selected other options!!
I cannot wait to get the phone in my hands and test it, i am sure it will require stronger battery to use its full capacity without compromising, so would open up and exchange the battery for sure.

I reckon this would be the best way to go. As soon as you pull off that cover you can kiss your warranty goodbye.
Something like a PowerSkin would be a much better alternative for Mugen.
Battery life on this phone is fine for me. I see no need to change the battery.
Considering that Moto/VZ are going to be offering the option to put the MAXX battery in the RAZR I wouldn't be surprised if more companies start doing the same.
That said, one advantage of having a very difficult to remove internal battery is that people can't steal your phone and disable your ability to track it simply by pulling the battery. Not go give manufacturers/carriers credence to do so, but I'd certainly pay to have an extended battery put in under warranty, though I would think it's cheaper to simply put something slightly better in to begin with.
Considering that Moto Maxx
Was considering that phon to. The idea of a original 3300 battery is just to good to be true... hope the other companies will copy the idea =)
the juice is simply not enough for a phone with such a huge screen, i voted yes and i am surprised with the capacity of the battery of htc one x.
Nah
From what I've read, users (somehow) have been able to get really good battery life out of them despite the huge screen and mediocre battery. I'd try it out for a few weeks before you throw your money at something you probably won't need.
I'm gonna say no. I like slim phones
You have your phone for 1 week and your battery sucks? Its not that the battery is very poor, it's just the fact that a LI-ION battery takes up to 2 weeks to be fully calibrated. We talk here about a new phone, with a battery that didn't run before now.
So give this little guy a break and try it for 2-3 weeks before saying that the battery life is horrible. If it lasts 1 day and some hours it is a good battery life for a smartphone with this huge display!
does replacing void the warranty?

As someone educated me on this I'll pass on the favor. Li-ion batteries do not need a breaking in period like old tech rechargeables. It has a specific amount of charges it can take before it no longer holds max charge, but it holds that maximum charge from the first day.
With the right settings a good sense ROM will get pretty decent battery. But I do feel slightly limited by the 1500 battery. It would've been nice to have easy battery modding from the get go.
Thank god I am satisfied with my battery life, in V ONE as far as I know the battery is not removable, right?
You can remove it. You just have to take the whole phone apart to get at it.

So my stock battery just wasn't cutting it as I would get at best nearly 4 hours of on screen time by using every battery saving feature I could think of, and always keeping Wi-Fi and GPS turned off. I ended up buying the Hyperion battery and this thing is s complete beast. Maxing my phone out, higher brightness, leaving GPS and Wi-Fi all on, playing games and watching streaming media, I can eclipse 4 hours of screen on time before I even get down to 60% remaining.
While this is great, it got me thinking that this battery isn't supposed to be more than double the life of the stock battery is it? While I'm certainly not complaining about the Hyperion, I would like to know if there is s better battery it there that would allow me to use the default case cover without making my phone huge and still allow for better battery life than I'm getting? I have two different stock batteries and both are exactly the same.
Are there any better ones out there that don't change the size of the phone?

Its possible. Motorola did it with the RazrMaxx. that tiny phone has a 3300mah battery. I wish some company could look into how they made it that small. i mean if Motorola can do it. samsung should be able to pack at least 4500mah into a similar battery. lol
i read this and it upset me cuz motorola always seemed to be behind on everything and i just never liked anything they put out. the razr maxx doesnt appeal to me but its gay that that it is better in so many different ways.

Pretty sure the battery size is larger than the S3 battery. I think the largest possible capacity they can fit into a original size S3 battery is around 2500mAH.
I'm not looking to match my Hyperion with a thin battery. I'm looking for a compromise. Something that'll fit with the normal back but will do better than the stock battery.

The Razr Maxx battery isn't that small. It is simply longer and a bit skinnier than the GS3 battery. Samsung could have done it with a slightly different design of how the battery fits in the back of the phone.

that is not what fast charge is. all fast charge is, is allowing the phone to take as many amps as possible from a PC connection. when using AC power (or good car chargers) nothing changes.
also, BTW, the faster you charge the battery, the less life it has. (as in in you will need to replace it sooner.)
Fyi, I have 2 Anker batteries. They're nothing special. They're on par with stock, just no NFC, but cheap. I rotate through all 3 batteries regularly and can never tell the difference.
Imho, this is really the best you can expect with a battery with the same physical dimensions as stock.

Any good news on testing the Hyperion, anker or mugen ?
A 3200mah pack can be the same size as a 2100mah..
There are a few things that come into play:
- The actual case thickness of the pack
- the cell count inside.
Internally we dont know how many cells make up a stock 2100 pack. Could be a single 3.7volt cell @ 2100mah or could be 2x 3.7volt cells @ 1100mah each(wired in parallel)... the 3200 could be one single cell.
So a 3200mah lipo verywell could fit, and perhaps it just a hair thicker but still fits..

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.
