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.
[HD2 Accessories] Curious!:
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.
[HD2 Accessories] xxljmzlxx:
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...
[HD2 Accessories] AntonJart:
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.

Sent from my HD2 powered by HyperDroidGBX
[HD2 Accessories] TheATHEiST:
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.
[HD2 Accessories] apallohadas:
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.
[HD2 Accessories] stevedebi:
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.
[HD2 Accessories] zarathustrax:
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.
[HD2 Accessories] optyqus:
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.
[HD2 Accessories] stevedebi:
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!
[HD2 Accessories] stevedebi:
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.
[HD2 Accessories] ashasaur:
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.
[HD2 Accessories] apallohadas:
I really hope that you're joking.
[HD2 Accessories] optyqus:
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.
[HD2 Accessories] AntonJart:
Read some feedback about this GOLD battery:
[HD2 Accessories] apallohadas:
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.
[HD2 Accessories] stevedebi:
Where did you get this feedback?
[HD2 Accessories] ez2remember:
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
[HD2 Accessories] AntonJart:
Ebay sellers that sell the same battery
[HD2 Accessories] experto1:
It might be gold, might be rubbish...

found this buyers statements for HTC GOLD 2430mAH BUSINESS BATTERY:

+ excellent product

+ great item

+ Got Item. Not the greatest but a decent enough replacement

- it ist a normal batery

- Refounded, product did not live up to expectations (Good Seller but bad product)

- Perfect. Great item.

+ quality battery

- batteria non conforme con quello che dice ! dura meno di quella originale!!!!

+ Got it and it works allright.

+ Fits and Works like a charm! Recommended!

+ I have gained at least 50% more uptime on my mobile

- Leave positive feedback, but not happy with battery

Statements are mixed but for a price of £9,99 (or EUR 11,75) it should be worth a try and some sellers give Moneyback Guarantee*.

"Refund / Return Policy

* If customers are not satisfied with our product, simply return the item to us in an unused condition and we will make a refund once we have received the item."
[HD2 Accessories] shahnowaz:
Just ordered for testing lets see what that thing is.I let you know after i received.

One thing it mentioned it is lithium polymar not lithium ion.

stock made with lithium ion.polymar came later.it is much better than ion.

what i know may be i am wrong.Dont say stupid or something else and even didnt find any bad reputation about the seller(except one).
[HD2 Accessories] Mister B:
It will be ion. I live in Asia & have friends who have tried these.

Current battery technology for consumer electronics has no battery material/technology that will double stored charge for same unit size.

Mugen tried to improve HD2 standard size battery capacity & the best they could do was about 5% increase.

Even NASA Science would have trouble matching these battery specs :-P

I respect you for actually parting with cash to test, would recommend filing for no item received so you get full refund & the lying thieving scum selling these products start loosing out.
[HD2 Accessories] :
LOL

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.[/QUOTE]

LOL that battery looks Fake as hell!!!! haha, i suggest you dont buy never know might end up frying your phone
[HD2 Accessories] shahnowaz:
i know guys but it says lithium polymar thats why ,it gots better power density than ion as per theory,

Besides my original one already gone so i need one if it is 1200mah thats also ok ,cheaper than original battery.hope it is not less than that.

Lets see what that thing is.
[HD2 Accessories] lucky_j1:
:)

aHa .. !! good shairing
[HD2 Accessories] AntonJart:
The difference in Lithium Ion and Lithium Polymer is that Lithium substance is liquid in one, and is solid Polymer in another. It can give the flexibility in terms of shape of the battery, but not the size.

So No, you cannot have smaller battery for DOUBLE the capacity.
[HD2 Accessories] apallohadas:
Ok, let's think about this. If you don't USE it, how will you know if you're satisfied or not?
[HD2 Accessories] experto1:
I copied it from one seller's page as an example but yes it's funny. I did not read it well but it's like: If you don't like what you see...

Everybody is buying batteries because of it's look, lol :)
[HD2 Accessories] stevedebi:
This is going a ways back, but I had an Ericsson R300 World, for which I bought an aftermarket LiPoly to replace the LiIon that came with it. The replacement battery was much lighter, and lasted longer. That phone didn't have any fancy charge meters available, so I was unable to see the difference in mA.

Not that I disagree with you - if it could be done, I'm sure Mugen would have made a smaller battery. Although maybe it is just too darn expensive, and it would not make economic sense (if such technology was a couple of hundred $$, for example).

This is one reason I suspect the Andida 1600; it is marked polymer, but it feels heavier than the OEM battery.
[HD2 Accessories] Mister B:
Polymer cell should be lighter as each cell is wrapped within a polymer laminate unlike Ion cells which are in metal casing.

The Andida battery is cheap china ****, basically standard design & materials with varying production quality & tolerance resulting in the varied user opinions we get, but for the money is an ok budget spare .

Personally I have a standard HTC spare & compact usb charge cell which is my preferred option as the HD2 stays slim & the battery door stays looking like new.

for major gains in battery capacity to size ratio you will have to wait for EPSRC to finish developing the porous carbon oxygen catalyst cell.

I sure the Chinese will release one first though lol :-D
[HD2 Accessories] AntonJart:
We better of suspecting all cheap chinese import for worse. I would rather save up few more bucks and get a better quality replacement. I read somewhere that those cheepo batteries are loosing its capacity pretty quickly.
[HD2 Accessories] hardlineratwork:
got the 2300mAh extended battery of Original HTC for about 30 Euro(uk import)

still no fake at amazon and qualitiy is fine

definetly no FAKE
[HD2 Accessories] xxljmzlxx:
looks very promising, but im highly doubtful of squeezing 2430mah into a slim factor size...
[HD2 Accessories] torrentulla:
don't even bother getting this as I have bought it tried for almost 5 days it does not even hold charge longer than the original 1230mah battery. with my normal battery hd2 works fine for a day. with this so called 2430mah battery I had to charge 3 times a day.
[HD2 Accessories] cmarti:
I got an Andida 1600 battery and will like to test it, what's the application you all guys use for that?
[HD2 Accessories] yslee:
To be honest, I don't mind the thickness. I mind the hump. Can someone do a cover that just makes the phone thicker instead?
[HD2 Accessories] stevedebi:
I don't see how that is possible, since the battery cover is only over part of the phone. This is as opposed to the TP2, where the entire back comes off.
[HD2 Accessories] AntonJart:
Are you using Android?

Current Widget from the Android Market. See how much % you lose in 2 hours of standby. With out legit HTC battery I get about 1+ hour of standby per 1% and 1-4 mA discharge
[HD2 Accessories] cmarti:
So there is no app that can tell me the real mAh for the battery, I been used just today and I think that yes it is giving me more battery life than the factory one.
[HD2 Accessories] shahnowaz:
ok just got it .after recharge full it last little bit less than 3h like stock battery .

(with everythings on full display power just left it on to see how long it last )

so it is not 2450 mah it just 1200 mah or may be little bit more.

how many days it last now lets see.
[HD2 Accessories] optyqus:
Thanks for reporting this. But please do around 3 cycles of full charge-full discharge to ensure the battery reaches it's potential. Maybe you'll get more time.
[HD2 Accessories] stevedebi:
I bought two. Both of mine show 12296 mAh when fully charged. However one of them seems to last longer. I've had them for a couple of months, so there have been enough charge/discharge cycles.
[HD2 Accessories] yslee:
The Samsung i600 shows how it's meant to be done. Only the lower half of the phone's rear comes off, but the extended battery cover still covers almost the entire rear of the phone. I wish companies making this could be a bit more imaginative.
[HD2 Accessories] stevedebi:
Is suppose it could be done, but I'm still not sure it would be stable with such a small battery opening.
[HD2 Accessories] tednelson83:
12296 mAh out of a 2400mAh battery? how? typo?
[HD2 Accessories] stevedebi:
I was discussing the Andida "1600" battery. I have used their stuff before. It is a quality battery, but never anywhere near the stated mAh. I had a similar experience with their battery for the TP2.
[HD2 Accessories] PKV:
So is it worth to buy such a battery ?
[HD2 Accessories] apallohadas:
Not going to tell you to use "search" but the answer is right on this very page.

"No."
[HD2 Accessories] stevedebi:
I find it to be an acceptable replacement for the OEM battery, but if you want "extended" capabilities, then no - it will not provide more power. But the price makes it a decent replacement choice.

EDIT: I used Andida batteries in my TP2 as well, and they worked well. So I think their quality is good.
[HD2 Accessories] Mister B:
It may be a good battery for the money, but I would not buy it.

I will not support these lying scum, state the real capacity or go under is my policy.
[HD2 Accessories] kolyan:
I am very surprised that original battery is only 1200....Nexus 1 has 1400, Vibrant 3G has 1500, and Vibrant 4G has 1600...and none of them even have 4.3'' screen
[HD2 Accessories] Mister B:
shocking really ! HTC went for sales of Wow factor thin phone.

Trouble is it's too thin for easy handling for the width of display hence why so many people drop it & break display.

Could of increased thickness by 2mm & tried to allow room for a 1600Mah battery.

HTC are incredibly good at wrong choices & poor quality speakers & components, still waiting to see a HTC device that has button quality that matches the old magician. Almost a case of 2 steps forward & one back :-/

Problem these days is everything focuses on high-tech & flashy design & functionality is luck of the draw !

Still love the HD2 but would never of paid the retail or contract rate, those sort of prices require HTC to resolve it's major device flaws of poor main speaker

(almost got it right on Diamond 2 with side port, just need to add one more for perfection) sloppy buttons

(got this right in the early days of magician & made the biggest mess of buttons possible with Diamond & released same d-pad design again on Touch Pro, total monkeys !)

sensible capacity battery units & more consistent build quality in general is needed, example of low quality would be the pathetic battery cover & securing clips of Desire & compare that to HD2 Kaiser or Magician ! ... HTC quietly bungling :-P lol
[HD2 Accessories] hx4700 user:
HTC are far from the only ones offering stupidly small capacity batteries, so don't knock them for that. Knock the press and pundits who insist on giving headlines to thinnest and lightest, the industry marketing people, and finally the public for buying them.

I have an HTC manufactured HP hx4700 and it is wonderful. No damage after hard use, the screen is the best I have ever had because it works in bright sunlight, and only the wish to combine phone with pda got me to change to my HD2. If it had a longer battery life, and the screen from the hx4700, I'd be even happier.
[HD2 Accessories] manemzjum:
The word extended in the naming of these batteries refers to life time not the dimensions of the battery

Otherwise it would be called the hd2 bigger or larger battery not extended battery
[HD2 Accessories] Hagenlund:
extended capacity and extended dimensions is mutually inclusive. you can't have more capacity without adding more bulk. this has been stated many times.
[HD2 Accessories] stevedebi:
I would disagree; it is possible to have the same size and more power, but it would also be more expensive. We don't see these solutions here at the market level because they are not cost effective.

At the same price points I agree completely with your statement.
[HD2 Accessories] Hagenlund:
you're prolly right about that, stevedebi. "... at the same price point" is more accurate.
[Atrix 4G General] legider:
So, when plugging it into a monitor and only using the cable, the only options that pop up is the "Multimedia" interface where you can only listen to music or see pictures/videos stored on the phone. Has anyone found a way to do a real video out so you can display your browser or certain apps like Youtube? Or perhaps even enable Webtop so you can view it over just the simple HDMI cable. I hate to have to buy a dock just to use Webtop.
[Atrix 4G General] Fixter:
That's not possible at the moment.
[Atrix 4G General] clubtech:
There is some value in the build.prop file that might enable this.

Look for ro.hdmi.mirror.enable=false

Change to true and reboot the phone.

See if that helps.

you need to be root of course.
[Atrix 4G General] Fixter:
Well that worked while the phone was booting. After it detects the HDMI cable it goes back to blank and then lets me choose between doing nothing and Entertainment Mode and none bring back the mirror. It was working fine tho. While it lasted...
[Atrix 4G General] Squeak22:
In the multimedia mode, is it popping up with the Windows Media Player like big icon's view on the monitor?

If so, there is a "Start Webtop" icon that should kick off the Linux webtop.
[Atrix 4G General] Fixter:
I can't do that. While you are in Entertainment mode you can change anything on the phone or it kicks out and the screen of blank.
[Atrix 4G General] MeX_DK:
AFAIK the Atrix doesnt have true HDMI Mirroring, only the LG Optimus 2X has got that. I might be wrong naturally.
[Atrix 4G General] Squeak22:
Right, you need to use the remote or a bt keyboard, I think.
[Atrix 4G General] Fixter:
But the mirroring was working. Except that when it detected the HDMI quickly when I unlocked my phone it went blank and asked me what I wanted to do. Entertainment Mode or Do Nothing and none of them got me back to the mirroring. If anyone has a solution or idea, let me know. I'll test.
[Atrix 4G General] clubtech:
Maybe there is an option in to disable that popup message / feature...

I'll be getting the phone tomorrow and i'll take a look.

Mirroring is working - but something is overriding it in the settings.
[Atrix 4G General] Fixter:
Yeah we need to write that down. It was working beautifully. I even so the Moto logo while it was booting and the unlock screen. As soon as I unlocked it OR it detected the HDMI cable, it kicked into another mode and overwrote that = true statement.
[Atrix 4G General] legider:
I will be rooting it tomorrow so I can dive in and see about getting true mirroring to work. But if we can't get it to do it, this may be a deal breaker for me. I can only assume it is possible somehow.
[Atrix 4G General] clubtech:
You can try to delete the following two lines from build.prop:

ro.hdmi.default.app=

hw.overlay.path.config=

back it up first!

Let us know if that worked.

I hope it wont cause a boot up problem (it should not but you can never know).
[Atrix 4G General] Fixter:
It is, theres just something overwriting it. I'm taking one for the time and I'll start looking at everything now and start tinkering with it. :P
[Atrix 4G General] Fixter:
That actually made me loose data connection I think? The H+ dissapeared. I have no idea how that has to do with anything but I went back to the back up and everything was fine. :P
[Atrix 4G General] kenio8185:
How about just removing:

ro.hdmi.default.app=

and keeping the other one.
[Atrix 4G General] ranova:
any word on this? I would love to enable true mirroring!

how did the droid x do it with this app:

[Atrix 4G General] exo8:
Same here, I desperately want this feature for hdmi out on emulators. I hate Att for crippling features, the bionic has hdmi mirroring listed as a feature.
[Atrix 4G General] zeta0134:
That doesn't do anything different. I've got it happily mirroring through the boot sequence, drawing the lockscreen and my security pattern to the TV, but just as soon as it unlocks, Moto's crapware takes over and away it goes. It never comes back until it reboots.

Forgive my relative ignorance with Android-- this is only the second one I've ever owned. Is there a way to bypass the restriction and uninstall either the Entertainment Center or the DockProvider packages? I have a hunch that it's one of those getting in the way of things, but I can't be certain.
[Atrix 4G General] ANDY12001:
anyone know how to get in mirror mode
[Atrix 4G General] Techcruncher:
there is now a hack. it doesn't do mirroring, but will make the phone go to webtop from hdmi. Then you just fullscreen the phone view window and your done.
[Atrix 4G General] link64dx:
Care to explain how?
[Atrix 4G General] malfuncion:
http://xdaforums.com/showthread.php?t=980193

That explains the mod, you dont get mirroring but in webtop mode it shows your phone as a small window. With your phone as a trackpad you can maximize this window.

As long has you have at least 1 finger or toe to type with and the ability to read you too can achieve this feat.
[Atrix 4G General] motoatrix:
please excuse a newbie here, so you can do this just only the HDMI cable?
