Don't do it - it is literally impossible to stick so much capacity in a battery for the DHD. There are tons of fake batteries on eBay. The easiest way to confirm they're fake is the rating
If you really want high capacity, the only option is the Mugen battery (1500mah), check the threads in this section.
Alternatively, try custom ROMs, since that will reduce battery consumption

Please try and stay away from those "business" or "gold" battery, I had the misfortune of getting one of those a couple months ago, the battery last quite long initially, but after 3-4 cycles they lost about 80% of their runtime, tried to get a refund but it was some shady ebay vendor, don't bother with any of those batteries, not worth the trouble, not to mention any potential damage they might do to your DHD due to their shoddy construction and circuitry

Yeah, I agree. If Mugen can't double the capacity without doubling the battery thickness - it probably can't be done. Last time I doubled the battery capacity, the battery was double the thickness.
The battery was excellent though and made by Mugen.(They even sent me 2 battery covers.)
Example for Toshiba G900: (Click for larger images)

I have one of them gold battery. Does not show real temperature stay on 24°C all time. Run time like on original. I wouldn't recommend it..

I got one, stock battery has more power, poor substitute

If I set myself up as an Ebay seller, with a 2650mAh Gold DHD battery for $15, will you buy it?
Or will I need to drop the price a bit?

you have to use BlackIce rom, your battery will last two days!!

Good one

Sad and annoying
the battery lasting one day is ferly sad and annoying. I was talking about batteries that claim they have extra amps but unfortunetley they are 99% rip-off's if they are the same size.... the only solution is a external battery case pack...
a bad solution but at least some solution

In my opinion we know very well how we use our phones. The battery consumption varies from user to user, from rom to rom and from location to location. So.... i think only same user with same rom in same location can see and feel the difference.
My experience till now with this battery is very satisfactory. I think is at least 40% better than the stock one. The things i think about now is the life cycle of it.

Quite old thread
Unfortunately until a new type of battery is presented the lithium ion batteries can't exceed 1300mAh for this tiny space we have. So anything above 1300mAh is fake
P.S. I wish there was some sort of control so they don't lie SO much and if they went that road someone could sue them according to some law

So is the physical limit around 1300? Beacuse I read 1600 in some other threads here.
Thanks!

is better to buy the original o similar.

I am quite satisfied with Momax x-level batteries. For me its better than the original batteries.

Battery Charger for my i9000m

I bought a momax 2700mah battery and Now i'm not 100% sure that the battery will charge via my phone, even if it does. it'd be nice to charge my stock battery for backup.
I'm looking into : Wall Charger
and this thing: Usb Charger thing.
I'm not really sure what to get tbh.

if it's the same voltage as your stock battery, I don't see a reason not being able to charge using the phone.
Anyway, it seems that both will work.
Also please make sure that you keep the replacement battery charged, meaning that if you're not using it make sure to recharge it once a month.
These batteries can break down if their inner voltage drops below a certain threshold.

the sgs has been known to detect some batteries as non genuine and won't charge them.

I buy a 2430MAh batery and it works fine with me. It have the same voltage of the original 3.7!

I've read that it is detrimental to the battery's life to store it while fully charged, just as it would be to store it while dead.
Since we're giving differing advice, I would suggest the OP look it up himself.

It seems to be hit or miss to whether or not the sgs knows it's not a genuine battery.. maybe it's a slight difference of voltage that triggers it, and it seems that it's the cheaper batteries that trigger it and the "oem" ones.

I've heard both, but going by my retail experience with these types of batteries. Most come precharged anywhere between 30-70%, so I can only guess that that is around the preferred charge percentage for maximum life of the battery as batteries don't move all too fast from the shelves. Heck my sgs had 70% off the start.

Question about Mugen Battery 1500mah

I'm very curous about this battery for Desire HD. From my experience, 3rd party batteries are generally frowned upon because they usually either
1) Does not contain the advertised charge (mah) amount
2) Does contain the advertised amount of charge but the battery spoils fast, and would be unable to hold charge properly after a few months of usage
3) Heat issues, etc, safety issues in general
It seems like many people in this forum have already got the battery and would like to know whats it like so far. my current original DHD battery has already semi gave way after a year+ of usage, it no longer hold the charge proper and I can only charge up till 60+% before it jumps straight to 100%, as well as battery level jumps erratically.
I went to check, seems like the mugen 1500mah battery http://www.mugen-power-batteries.co...ery-for-for-htc-desire-hd-softbank-001ht.html cost around $45 US which translates to roughly $56SGD whereas locally the original DHD battery costs $59SGD. Adding a couple of bucks for shipping and all, it definitely works out to be a better battery to purchase if it actually works well (e.g. refer to above criterias).
So I would like to know whether the battery suffer from the problem of holding charge and also any heat/security issues. Considering I've read that many people claim that they get a lot more battery life out of it in their initial usage.

If you can live with a modified battery cover then this is superior to the mugen battery and cheaper too:
http://forum.xda-developers.com/showthread.php?t=1344761
Big advantage here is you can use an original sensation/evo3d battery from HTC and don't have to have rely on 3rd party batteries.
On the other hand you can get as much as 1900mAh instead of the 1500mAh mugen offers.

As a matter of fact I have skimmed through that threads and I don't find anyone talking about how the battery life performs after months to a year of usage. This is a common concern because many 3rd party batteries lose their ability to hold charge very quickly after a short period of time. Of course it can be argued that no one complained about it in the thread but thats not substantial enough. The uesr reviews thats stated in those thread that you have linked are mostly by new users who were "wow"ed by the battery and then stop coming over to the thread altogether.

Even if they would reply, you wouldn't be able to use their statements because you don't know how they treated the battery so far.
I received my Mugen battery lately and I will be handling it the way I learned from here:

I have been using the Mugen battery for about a month now, following their instructions on how to handle the battery during the initial charges.
First, you say "3rd party batteries lose their charge.... after months to a year". Well, my original HTC battery after one year, is - I estimate - about 50% of the new Mugen.
OK, a new battery will outperform an old one, but it's not just 3rd party batteries.
When I changed batteries, the OEM one had actually expanded slightly and it did not slide out of its compartment easily. So the OEM is not a perfect guarantee of a lifetime of high power and good behaviour
And, I spent the extra € on Mugen and not the 2000mAh cons from eBay - Mugen has built a reputation over time, it is built to a similar (or higher?) standard as the OEM's.
btw look for a coupon that is valid for 10 or 20% I recall off the standard Mugen price.

test1800mAh
Many businesses will pretend to be the large capacity, we choose the best choice in the factory, so the quality guaranteed some. I bought a nominal capacity is 2300 mAh, I test the actual can reach 1800 mAh.

does it give you much better battery life?

So if im charghing my battery and it jumps to 100 from 74pct it shows that my battery is in bad condition?

There's a lot of people that are satisfied with Mugen, even here on the board.
http://forum.xda-developers.com/search.php?searchid=12986796
I personally don't care if you don't believe that.

I used a battery testing widget when I first got the mugen battery about 2 months back...
It was around 1300mAh with maximum 15% deviation, stayed around that value for the charge cycles done during that period, for about a couple of weeks.
I'd say its definitely pretty close. My HTC battery was at 800mAh with maximum of 20% deviation by the end of 1 year.
(Deviation comes from the limitation of calculating the mAh if I'm not wrong. Because it takes value of the actual consumption / charging once every minute or so, it kind of either interpolates between values, or just assume the whole 1 minute being the recorded value. Hence the possible variation.)

Of course you don't, but no, ignorance is not a replacement for knowledge.
Actual testing (250 mA drain until shutoff voltage) shows Mugen to be wrong. Where is proof that you're right?
For the OP: http://www.amazon.com/Motorola-Univ...able-Packaging/dp/B00486MH80/ref=pd_sim_cps_6
That should give one full charge of the Desire HD from 0% to 100%. It's about the size of the phone, but thinner.
http://www.amazon.com/Anker-SlimTal..._1_6?s=wireless&ie=UTF8&qid=1334818005&sr=1-6
This should give around two to 1.75 full charges.
I would highly suggest going with genuine OEM batteries to get the maximum you can get. Always ask yourself: If it was so easy to get more battery capacity into the phone, why didn't HTC do it?

Also showing 1214 mAh with +- 41% deviation while on daily use, with no complete charge/discharge cycles that I made in the beginning, after I had received the battery on March 13th 2012.

They tested a Mugen battery, which consistently shows that they overrate batteries. By default, the rating of the battery is in serious doubt.

Your own phone is telling you that you're getting exactly OEM capacity, maybe less. Battery Monitor Widget extrapolates what it thinks your mAh rating of the battery is based upon the voltage and the mA consumed to get to that voltage. So far it looks like your battery is either OEM capacity or slightly less. The top 1526 mAh number is what the battery claims to have, not what it really has.

1. Your test app is proving you wrong.
2. Phone based test applications are a horrible idea, proper testing should be done with the battery charged outside the phone to 4.2v then discharged to 3.4v at constant mA drain. Multiply the time that it took to drain by the mA drain used to get your accurate capacity.

No. This is how the app works: This value (1214 mAh) was measured by not draining the battery completely anymore. If I don't drain the pack to 0%, the app cannot measure all the capacity. Simple logic.

If it's 2450mAh and the same size as the original battery, it's fake.

I've seen these gold batteries before. Often they are OEM batteries with a fancy sticker on. Don't be fooled. Run it via a battery test, or even use Spare Parts to check the capacity. Also, avoid the placebo effect, your phone might seem to last longer and because of that you think it's a good battery but it might be simply because the battery is newer; you should consider does it run better than when you first had the phone?

If "Item location: Hong Kong, China" doesn't say enough, the free shipping and outrageous capacity claim should tip you off that it's a burn. It's just a low quality knockoff battery with a flashy label.

It's a fake.
If you want more capacity you need to buy a bigger battery and the cover to contain it, there are no other options.

Not a precise measurement. Orginal runs about a day. This one half a day with not much activity. It has a jump from 30% to zero. I had several full charges/ discharges before. And several attempts in trying.

lithium batteries should be kept between 30 and 90 %. It's worse to discharge them.
You could charge to only 80% but 90% is where on most phones the battery statistics reset

Sure, these are recommended usage conditions. But jump from 30% to 0% likely means defective battery, which cannot hold its capacity.
Normal battery should go smooth from 100% to 0%. Well, it may be not a straight line, but under constant average load graph should be near linear.
If it's jumping and suddendly goes 0% it's something wrong with battery. You may still try to calibrate it by full discharge/full charge several times,
but high quality batteries usually don't require it. Also I think high capacity battery must be thicker than original. If not, it's most likely a fake.

Decided to stick with the OEM battery, and will continue purchasing them if they go out or need to swap. Because of build quality, coping with a dead phone is better than one on fire or overheating.
But if Motorola or Anker releases an extended slim battery...
