Well if it was thin it wouldnt be an "extended" battery would it? The whole point is that its extended to fit more power into it.
If it was easy to get more power into a battery then HTC would already supply them with the HD2 and extended ones wouldn't be needed/wanted.

apperantly you dunno anything about material science.
CAN'T a new battery with a better performance with SAME SIZE come out? Oh of course no! cuz it doesn't have bigger size.

Don't think there are any worth considering... there are 1600mah batteries on ebay but the overall consensus is that they're just about the same as ome battery ... it would truly make HD2 a much better phone if they can just extend the stock battery by a bit...

Apparently your logic and maners are weak. If you bothered to flip through next two pages of this section, you would find at least two threads about batteries. In those threads you would find that there is no slim extanded battery in existance for HD2.

lol, your scientific/logical huge brain obviously missed the point.
You asked for an "extended" battery, that would infer you wanted one that was "extended" beyond the normal limits. Currently the only way to get one that is beyond the limits of the ones that are supplied with devices are to buy ones that are "extended" meaning they are larger in dimension and hold more power.
Currently you CANT get a battery for our device that has the capacity of a extended one unless its "extended". The ones you see on ebay and other sites saying otherwise are FAKE.

You should dial back the Smarmy attitude amigo. Athiest is spot on by the way. The only way (currently) to have an extended battery for the HD2 is to make the battery larger.

I suspect that if someone made a genuine Lithium Polymer battery instead of Li-Ion it would indeed hold more charge. But I have not seen any such. The Andida is listed as LiPoly, but it can't be - it is basically the same mA as the stock battery.

Mugen has a 1300mah battery, which is a little more than the 1230 or 1250mah the stock battery comes with. I think I get a little more time with my mugen battery than with the stock, but never ran any definitive tests. But mugen is probably the best you will get with a battery the same size as the stock one.

Why do you guys disinform people? As a matter of fact there are "extendend" batteries that have the same size as the OEM batt. Where it is written that a battery extended in power must also be extended in size? Of course, there is a relation between size and power, but this relation might vary depending on the materials and the technology used.
Here you have a 2430 mAh battery (the "famous" business gold battery, which no one here bothered to test), and the seller says it has the same dimensions as the original one. If this battery has indeed 2430 mAh remains for us to find out. I'm thinking to buy one, just to test.

Nowhere in the add does it state that it is the same size as the OEM battery. I'm wondering if it really is; from the picture angles it is difficult to tell and might be deeper. But it is probably the same.
However, the packaging looks amateurish and suspect. This almost looks like a home-made wrapper.
Let us know if you order one!

Gold Battery
OK, I asked the seller about the size and if it will work with the stock cover, here is the answer:
"Hi,
I think it will work with it and the battery has a same size as standard battery."
On looking at the pictures, the batteries may be from Japan, but that is Chinese writing on the battery... or at least it is identical to my Andida "1600" writing.

Yeah...I would'nt put that battery into my HD2...seriously, that looks sketchy as hell. IF it turns out to be 2300mAH, which I highly doubt...it looks REALLY amateur-ish. It's all about memory management people, close crap thats running in RAM and your stock battery will last literally ALL day.

I really hope that you're joking.

Well I'm not, call me stupid, call me whatever you want but I do believe what I said for a main reason: one of my hobbies are rc flying models, both electric and with combustion engines. In this hobby you need powerfull batteries for controllers or engines (NiCD, NiMh, LiPo). I have a range of these batteries of different capacities and some of them have the same size but different power (eg: a 750mAh has the same size as a 2200 one). Of course, the ones that are more powerful are not cheap, but it's money well spent.
I'm not saying that the ugly looking "gold"battery which seems to be wrapped by a 5 years old kid has 2430mAh, but it worths tested. I just want to put this battery on the ohmmetter to read it's values. Regarding the safety for my device, I used chinese batteries on other phones too (spv m3100, kaiser) and none exploded, got bigger or overheat; they do loose their capacity much faster but if you are on low budget a 10 bucks battery saves your as* for a couple of months.

No one is calling you stupid, but you do seem ill-informed.
Cell phones are not the same as hobbyist 3rd party suppliers. Batteries for rc devices are much more third party friendly than cell phones. What we're likely buying from these Chinese manufacturers are probably cast-off batteries that didn't make it through quality control.
Sometimes you get lucky, sometimes you don't.
I asked if you were joking because the battery you linked was blatantly sketchy. It isn't even worth checking unless you just like to throw money away.

Where did you get this feedback?

I wish people would just give up trying to find a higher capacity battery which is of the same size. If it was that easy wouldn't you think HTC and ALL major phone manufacturers with their vast resources wouln't want the same thing? A few mm less in dimensions or a higher capacity battery can mean far better sales (millions more).
From experience with tons of mobile phones and 3rd party batteries they have always come out worse 99.99% time. Most of them are cheaply made where they blatantly lie about there actual capacity, don't meet safety standards, can explode, can bulge, overheats etc.
How many more threads about these cheapo batteries quoted with much higher capacity that is pulled out of thin air.
Not to rant but if you want more juice I recommend you get the official HTC extended 2300mah or Mugem battery. I'm afraid you can't have a thin phone and more juice. end of

Ebay sellers that sell the same battery

(Q) Ultra-High Capacity Samsung AB653850CE Gold Battery - 2430mAh

Have anyone tried this????
The ultra high capacity battery for Nexus S, boast 2430MAH but has the SAME SIZE with the original battery!!!

It's not the real capacity.
Put it this way: the OEM batteries are made with almost latest Li-Ion technologies. Unless there is a breakthrough discovery which will double the amount of energy stored per volume unit (in which case you will see this all over the news) any battery that will claim more than 10-15% energy boost in the same volume is a fake.
Take as an example the Momax batteries.
They've achieved to put 1700mAh in a battery the same size as the original 1500mAh used for Galaxy S (I had one of those on my ex GalaxyS) and indeed .. it was "a little" stronger than the original. Anyway, in order to get 2700mAh, the Momax battery got double the original volume (I also had this huge battery and indeed, had the claimed capacity).
Now ... just look over the internet after the manufacturer of these wonder batteries you're asking in your post and see if they really have the reputaion for "super-batteries" ...

Also Seidio make ultra batteries but are too big.

thanx for these info

I was about to buy this extra battery with more power. Thanks bro ... will drop i decision.

Is there any battery with a bit more capacity then the original one?
i'm going to buy a second battery and therefore i'm glad for any hint which one is good (and cheap)

I found a review on Amazon for this battery. I always take these with a grain of salt as there are so many variables to conclude "Your Results may vary".
I found the OP's 2430 Double capacity battery on Ebay. I went through the reviews and a few savy users stated something similar to this.
Let's call it fraud. I was not expectin a 2.43mAh but gettin a 1367mAh is bad!

What a waste of time and money. I followed the instructions exactly. Charged it for 5 full cycles and allowed it charge after it was full. This is labeled as an 'extended battery' yet there is no extended life to speak of. If anything it at or worse than the original battery it came with. I also was experiencing more of my programs force closing than usually. If this battery was only $19.99 than maybe I wouldn't care as much, but at $50 you have to get what you pay for. Avoid and get an extra OEM Genuine Samsung Battery or an extra wall charger for work.

Researchers increase charging capacity, speed of lithium ion batteries by a factor of ten
So ... maybe in about 3-4 years, along with multi-core phones, we will see also super-duper batteries .

REF: Gold Battery 2430mAh on eBay...

Lg l7 battery fits our OB just fine :)

EDIT:
Do the following at you're own risk.Even though it works for me and there is no logical reason it wouldn't work for you.
My wife got a new L7 couple of Weeks back and i have been paying with it every now and again.
As the battery on the OB is experiencing bad drain lately i thought to look for replacement. Tried other battery with no luck and than last night thought what the hell i will try the L7's battery.
Hell yeah ! Fits nicely ( but the OB battery had to be filled a bit to fit in the L7 , just in the right corner about 1mm on 1mm).
Now to the nice part. As it is a new battery the self drain is gone.
And it is 1700mAh
Although i will have to return it to my wife as she is gonna be in a shock as her phone is gonna be dead before tonight The big question for me is is the L9 battery the same size and would it fit as well .

I forgot to mention with the original battery the current drain is about 1% every 2 minutes .
But this is due to me using the phone a LOT. At least one and often two charges a day for year and a half so long gone the 300 charges which are supposed to retain 90% of the original charge.

can you take a picture of your p970 backcover battery?

Here goes the pics, sorry about the delay.
P.s. Pics are from the old trusty s8500 aka wave. L7 camera is crap

So L7 battery is 3.8 volt our p970 battery is 3.7 volt.Cant it be any damage on main board?

Wouldn't think so. As both mobiles work fine with swapped batteries

And during charging voltage is way higher anyway. Remember 5 volt charger

That's a nice find! Good job! Might buy a genuine L7 battery...

I am glad to share
But as for the L9 looks like different shape and contacts positions

Thanks gor info:thumbup:
sorry for my bad English

So is it safe despite the voltage difference?

So far so good. One day use and it is great. 4 hours + screen time compared to 2.5 (again worth repeating my original battery is degraded)
I even find data connection working better, but that might as well be fruit of my imagination.
Best part is my wife hasn't caught up yet .

Yes. Don't use it. Just because something fits doesn't means it is supposed to work. For instance I am pretty sure if I try I can fit my phone in my mouth. Is that good? NO!
You won't notice it short term but long term it will bite you and Lg can refuse warranty if it's damaged due to incorrect use.

super correct , if this was the deal lg simply would have included it at least in the models of today , but the main board will suffer on long terms of use :good:

Actually my neighbour is using razor xxx batery in his phone and that's half volt higher than his original battery.
The problem for the main board is not the voltage itself but the incoherent amperage and power consistence, and this battery is lg made so complies to their standard.
Again remember that the phone runs ok on charger which happens to be 4.8 volts without battery inserted.

Of course it's not the voltage itself, but the increased voltage causes increase current and that increases heat output and that does damage your phone.
Try this yourself.
Create a two circuits with a two identical light bulbs. Use a battery one battery that is 1.5 Volts and use another thats 3 Volts. Which do you think will burn out quicker?
And the fact that it's 1700mAh doesn't necessarily mean it gives longer battery life it might just mean that it has a higher current output.
You can use that battery if you want. I wouldn't.

It's 0.1v of diference, I don't think that could break the phone or something.

The heat output of the CPU is directly proportional to Voltage squared and since the change in temperature is equal to the Heat Ouput minus Heat Disipation the result will be a lot hotter than you think. The hotter it runs the higher the resistance in the circuits the more power you have to us to keep it running stable. Can you see why even a small difference in voltage makes a big difference.

[Q] Battery overcharging

Hello.
With Current Widget I measured voltage during charging... In 100% it is over 4.35V what is, I think overcharged, because Li-po or Li-ion have max voltage 4.2V per cell. I have rooted phone, but stock ROM and stock kernel. Can rooted firmware change charge specs. or this is way how SONY damaging their batteries so people have to buy every year/two new phone or new battery?
Thanks for answers.

It's 0.15V of difference, it do not hurts or anything. Sony do not plan to ruin your phone. You are just paranoid on Stock Rom...LOL...

I'm working with Li-po batteries in RC planes and I can tell you, that 0.15V overcharged can significantly decrease life of your battery. But it is easy way how to increase capacity of battery, but it is very bad way.
So, those limits are controlled by Kernel, yes?? And when I flashed different FW to root my phone, it didn't changed kernel, so I probably has stock kernel?? Thats the main question for me, because with previous experiences I rather stay at stock kernel and stock ROM before flashing anything custom.

You can stay on Stock Rom and flash a Custom Kernel, for that you have to Unlock Your Bootloader, and play with the settings or anything to undervolt the charging, but I think is not that simple.

On more than one occasion I've seen you post and give horrible information, in most cases, very wrong because you don't know any better. If you don't know something, DON'T COMMENT ON IT.
0.15V is a big difference when it comes to batteries as small as ours. In a car battery, sure, 0.15V isn't that big of a deal, it's less than 0.01% of a difference, something that can naturally occur with impurities in the lead/acid components, magnetic shift or hitting a speed bump too fast. However, on a battery the size that's in our phones? That's a 3% difference. 3% variance is MASSIVE in relative sizes.
I'm not saying don't help anyone, but don't fake answers in hopes someone clicks your thanks button.
On topic:
In the past, have you flashed a 3rd party kernel at any time, for fun or testing, or for daily driver use? (Even if you're stock now)
How are you plugging the device in - USB port on a computer? USB port on the side of a surge protector? If it's a computer port, is it USB 2 or 3?
Are you using the stock charging block and stock cable that came with the phone? A 3rd party solution like Belkin, etc.?
If you have access to one, plug into a car cigarette lighter, either Sony or 3rd party, do you see a change in the overcharge values? What about a magnetic charging cable?
Have you opened up the phone and tinkered with anything?

Just going out on a limb here but have you checked the app is actually accurate!!

The only way you're going to be sure if that voltage is accurate is if you use a multi meter, apps only read what the phone reads and outputs, which isn't always accurate, try getting CPUZ HW monitor for your computer and check your 12V rail, you'll find that it's nowhere near accurate whereas other apps will give an accurate reading, with this being the case there is no way of knowing which one is accurate and which one isn't, a multi meter is the only way. But in all fairness you're probably going to be using your phone for around 2 years so with that in mind does it really matter?

On more than one occasion I've seen you post and give horrible information, in most cases, very wrong because you don't know any better. If you don't know something, DON'T COMMENT ON IT.
0.15V is a big difference when it comes to batteries as small as ours. In a car battery, sure, 0.15V isn't that big of a deal, it's less than 0.01% of a difference, something that can naturally occur with impurities in the lead/acid components, magnetic shift or hitting a speed bump too fast. However, on a battery the size that's in our phones? That's a 3% difference. 3% variance is MASSIVE in relative sizes.
I'm not saying don't help anyone, but don't fake answers in hopes someone clicks your thanks button.

Take it easy dude, on more than one occasion i've seen him give perfect advice and to keep things real i've seen mods and elite developers make bad decisions and give bad advice out because they simply thought they knew, give him a break eh! Theres ways of saying things to people if you have a problem, like not doing it publicly, if you voice your concerns properly then no harm no foul, personally if you'd have just said that to me i'd be annoyed.
Just a heads up.
And as i've already said about the voltage offsets which have been talked about, in all fairness it's a negligent difference and won't matter in the overall scheme of things.

Is it possible to connect 2 batteries and use as one?

I've got two original Samsung note 5 batts. They currently have 2300maH and 2800mah capacity left.
I searched online for this, I only found here in xda a threat, someone said that if batts are same model and parameters connecting them might work....
Please comment

Probably not a good idea. If one shorts internally it may get fed by the other. Double trouble.
May screw up the power controller ability to effectively monitor charging and lead to a Li failure.

Right...thanks for this

You should probably pass on that....

You can try it. I'm not real keen on the Frankenphone thing. Using frequent midrange power cycling (40-80%) may be a better plan.

what will happen if I connect battery for another model of samsung, something like 5000maH? (assuming, the batt. has same voltages..and parameters)

It will probably charge normally as I believe the charging is voltage based. Whether the battery thermal sensor will work correctly is another concern. That is important as it helps set charging rate and the under/over temperature behavior of the controller. It may take longer to fast charge as the power controller circuit may not be able to sink that much current.

ok, thanka for the information.I could go deeper to check if a script could make custom-management of th. sensor ,based on diff. parameters of battery, but I even if it can, there would be other problems i guess; lost cause

You're welcome.
People do create Frankenphones using huge batteries but they are awkward and more likely to be damaged in a drop. As glaxys graphically illustrated it's a crap shoot if it will go supernova on you. An optimized Samsung will generally get good SOT with the stock battery.
