I have ordered 2 high capacity batteries for my new HTC HD7 and DHD.
They are simply higher capacity batteries but not made by HTC.
The Desire HD battery is 1600mah (standard is 1230mah) and
The HD7 battery is 1500mah (standard is 1230mah)
My DHD is aweful with its standard battery - I won't even touch it once in the day and after 6 hours it will only have 1/4 left of battery!
The HD7 is much better and seems to last the whole day with call and text use but it is always on its last legs towards the end of the day - I imagine that these batteries will offer at least another 2 hours of good use a day to these phones.
My question really lies in the safety of these batteries... they are not HTC batteries - they are made by some oem somewhere in china I would guess and I don't know if they are likely to leak and damage my phone or not with extensive use. Does anyone have any actual experience with such batteries on their phones?
I did actually buy 2 spare oem batteries for my Nexus One from eBay and have never had problems with them however I have never used them for a sustained period so I don't know for sure...
i am also interested in this. ive seen a few 1500mah batteries on ebay. but my concern is if they are really 1500mah. they could just throw a sticker on there that says so.
as for safety, as long as the batteries output is equal to that of the stock hd7 battery i dont see why there would be a problem
you'll have to let us know how they work when you get em. i might end up just getting one here pretty soon though
It's not recomended and it is risky.Those batteries can really damage your phone and in some extreme cases you can even lose your warranty.You can find this hot topic in various forums, I read a Blackberry user buying one and after 3 months working presumly better the battery started to literally mealt, ouch ! (could have been a bigger ouch btw lol). I'd wait for an extended battery but I'm new to the world of HTC and don't know how they would react. Nokia in 2006 launched a program which replaced some particular batteries and delivered increased cappacity back.
OR buy a 2nd original battery. It's the safest decision and 2460 is still better than 1500
I bought a battery like this for my Treo 700wx. Worked great for awhile and than it started to die really fast. I put back the stock battery and it would even start to die on my pretty quickly. After that, I never would buy another extended battery. Seems hit or miss but just wouldn't trust it again.
^ Exactly. Forgot to add that their cycle life is a lot shorter. While with an genuine one you could go even for years, for an extended one you should expect 6-7 months at best.
Don't buy these batteries. They all look the same and I'm guessing originate from the same supplier. I bought one and it didn't fit quite right, and I worked out the label was misaligned, so I peeled back the label to line it up and low and behold the battery itself said 900mah despite being labelled 1500mah and "replacement for desire hd".
Blatantly trying to rip off users who are desperately trying to get a little better battery life, ironically they are actually getting a lower capacity battery! Beware! Also note, I've had my hd for a month now and the battery life has improved hugely, I always get a full day now! Although its in power save mode by bed time. I have though invested in an external 5000mah portable battery charger for use when I know I'll be away from mains or usb, a much safer option.
Cheers!
Ps this is by far the best smart phone I've owned, iPhone, blackberry storm, palm not a bit as good as this, wish it could deal with outlook meeting requests though, ie accept, reject, send...only fault, and I can live with it for how amazingly it does everything else.

I've bought plenty of generic batteries and have yet to have my phone blow up in my pocket.
So I have been running two 3500mah batteries from 2 different vendor and one hold a lot more charge than the other, probably a faulty one. Went ahead ordered two more extended for longer usage.
Does anyone have really good experience from ebay seller that you get the same consistent quality every time you order or is it a hit / miss situation?
Can the kernel play any role on a different capacity battery?
People that run multiple 3500 mahs, do they run relatively same? do you wipe battery stat every time you swap?
I can get 40-50 hrs with light wifi radio use
I got a good battery from http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=260798018307&ssPageName=STRK:MEWNX:IT
a bad one from http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=220771384257&ssPageName=STRK:MEWNX:IT
It's only bad because it doesn't hold as much charge, and when you use it for a a few task the battery would drop 1-3% just because maybe using it updated the percentage? but this happens a lot after it goes on stand-by.
It could've just been a bad batch.
The kernel definitely doesn't effect battery capacities; however, I do believe it can effect the rate of consumption depending on the coding, if I'm not mistaken. During my experiences with eBay non-oem batteries is that they aren't great quality and fail a hell of a lot faster than oem batteries. I do a lot of research before I buy so that's saying something...hope this helps
Theoretically the battery can last longer or shorter depending on that setting.
The oem does pretty well holding its charge.
How long does your battery last and which rom?
Where do you get your supply from?
Model : EB575152VA is what I'm seeing being sold from a few places and what came with my phone.
Wonder if that's what you have?
Has anyone tried this GOLD 2430MAH BUSINESS BATTERY FOR DELL STREAK MINI 5 battery here? (Just check it out on ebay, i can't link it because i'm a new user)
Wondering if its worth getting it or if I should just get a cheaper pack with a charger and 3x 1800mAh batteries? Mainly looking for an extra battery to take with me on long car trips so I can use the phone more like a tablet, but I wouldn't hate having a longer lasting battery for daily use either and then using the stock battery as my extra.

this looks interesting..one thing good about it , is that is the same size as the original dell battery.
I think its a fake capacity, the largest capacity that fits as standard size offered by a decent battery manufacturer, Mugen Power is 1800mah, and if you read the threads here, there is a 2400mah extended battery that has to use a custom battery cover because the battery is twice the depth of the standard battery.
So, i think you will find its not really a 2430mah battery, but a 1800mah battery at best.
if it seems too good to be true...
The best bet is to get one of those external battery packs with 3000-6000mah and a spare cable.
Also be agressive in your control of screen brightness and data use
If you read the feedbacks of that seller on eBay. There are heaps of negative feedbacks from buyers calling him a CON.
I bought off amazon since it had to be shipped to India... think there was only 1 seller in Amazon and he seems genuine.
There's a point with batteries where to make them any more powerful you must make them bigger. If fitting 2430ma into an 1800ma package was possible Mugen would have done it, so yes the rating is a lie.
REF: Gold Battery 2430mAh on eBay...
Total fake and ripoff!! ...so dont be wasting your money...

Sorry. Thought you asked for the regular 2400mah.
hi, i bought this battery 2 mounth ago and my phone authonomy is double now. so dont coment if you dodnt try!
Do dell sell them?
Probably a con, but what the heck… I just purchased it. If it’s not 'as stated', I’ll report the bugger.
could keep us posted about this, i looked at the seller's feedback and seems it is fake but wondering if that is true.
The Americans have a saying "You can't put a quart in a pint pot" and that applies to battery power as well. Don't waste your money.
Irritatingly, battery capacity is only shown on the battery itself and not in the device’s battery info. So, is it really 2430mah? Don’t know. But there IS a difference. The 1530mah stock battery ran out of juice alarmingly quickly – like falling off a cliff - when at 30-40%, yet ‘Business Battery’ allows heavy use (downloads, browsing, video… etc) right down to single digits. So now I can use Streak much more (I’d say several hours more of constant use) when battery level is below 50% without worrying if it’s going to suddenly die on me. No gain between 100-50%, though.
I was prepared to slag this off, but from my experience it’s genuinely longer-lasting, especially at low battery levels. How long the battery itself will last only time will tell.
I’m not prepared to test it against Mugen’s 1800mah and spend near 30 quid (plus £18 p&p) in the process.
I've read elsewhere that the cheap Chinese batteries often don't report the available power in as many steps as a 'proper' one does, so they appear to fall slower.
I don't know how old your Dell battery is but it might not be as good as it used to be when new.
Yep, I had to replace the Dell battery (after about 10 months use) because over the past week it became completely unstable – dropping to 70% after 30min use, suddenly back up to 95%, and plummeting from then on. But the stock battery right from the start was always weakest when two-thirds empty, and it drained juice even on standby. Last night it was 100% or ‘fully charged’ for over 3 hours (mostly on standby and some light doc editing)… that had never happened before.
The thing is actually stamped ‘made in Japan’… aren’t Japanese products supposed to be expensive? Looks suspect, but whatever. If it becomes unstable after a month or two then sure, I’ll invest in a nice new Mugen or Dell replacement. But as of now I’m fairly content with a £13 Ecell batt.
Got one of these last week, & have put it through a few recharge cycles etc, unfortunately, it's no better than the stock battery
Oh well, it was worth a try..
As with all cheap batteries it has a short life - no more than 2 or 3 months before it starts to rapidly drain. As a temporary and inexpensive solution it's fine, but don’t expect long-lasting quality.
Disclaimer: I know there is already another thread on Mugen HD2 Extended Battery 2,600mAh, but I would like to state that this is an official review since Mugen has provided me with a review unit to debunk the many bad comments given concerning their battery quality. This you can read from http://forum.xda-developers.com/showthread.php?t=1294124.
[BACKGROUND]
I have contacted www.mugen-power-batteries.com directly after hearing many comments concerning their false claims. I was surprised that they actually responded by providing me a review unit of the 2,600mAh. It is now on the way.
My review unit will be coming in about 2 weeks time. I will try to conduct an extensive review to determine the actual worth of the battery and whether they work as advertised. I will be conducting a few tests specifically on the battery, as objectively as possible. This would cover video playing, 3G usage, full valuation of the battery charge (using battery widget pro) to name a few.
If you would like a particular test to be conducted on the battery, please state and give a few ideas below. I will be comparing them against the original 1,230mAh from HTC.
I think as faithful users of our HTC HD2, I would really want to get the best extended battery. If this provides even 90% of the advertised capacity, it is already worth the money. Anything less would be pointless.
Thank you.
Larger cell will indeed be good but 2600mAh will be higher than reality as Mugen have admitted this already in a round about way on responses to another testers results.
A new standard HTC cell & new standard size 1500mAh Mugen is the test that needs to be done.
Any chance of a sample 1500mAh review unit ?

I will try to get a 1,500mAh review unit after this one is done Oh, have Mugen admitted to that? Would be good if you can provide me with the link. Thanks!
Cant Wait for the review
Im Planning on getting one myself a 2,600mAh

This was response to Dougs battery testing.
Not in any way slating Mugen but the mAh ratings marked on their cells are higher than what would be achieved in any lab test.
1500mah is the one I would love to see tested side by side with genuine cell in device & technician mAh testing.
Mugen cells are ok quality but for the asking price we need total transparency on actual cell capacity ...
I have no idea how good that battery is, but I bought this one about 6 months ago and it's working very well, doesn't gain much heat and it doesn't discharge itself much. Average battery consumption in standby is 6mA. All I can do is recommend you guys this one. And cover is really strong. And it's "bit" cheaper than Mugens
[email protected]/MB434B/review_MB434B.html
looking forward to seeing your test results...i just got me a 2400mAh battery and it lasts me about 15hours under heavy use...
Hi guys,
Sorry for the silence... I just received the battery today! Give me some time to get it charged and conditioned for testing
Let me know what else you would like me to test it with.
Display use is interesting for me, such like browsing etc.
Open a browser with some ads or something and look how long the Battery live..
My Galaxy SII gets there 4,5h.
Start the Match
Idc really care about that battery. I know its fake, but is there any real battery that's better then the original stock? 1400, 1450, 1500?? Not the fat ones with the kickstand
Just an update, I am still conditioning the battery. The first charge/recharge was really pathetic, at 12 hours before it was flat (moderate-heavy use). The second charge/recharge is much improved, I am on 25 hours on (moderate use) with 25% left (taking pictures, listening to music, games, surfing, etc.). I will begin formal testing after 4 full runs to find the optimum condition.
One things I have to say is that the ROM does play a high factor. I was on Dorimanx 3.0 and somehow the governors for oc/uc is not working properly as I kept getting some high drainage. Once I reverted to 2.9, the drainage was gone and it seems to sip battery at a much, much lower rate.
So many factors!!!!
By the way, I really like the battery cover. It is not cheap like the other China made products (unlabelled). I have already 4 different covers, and while I would prefer a metal back cover, this is the 2nd best
Can You please also start the heavy display usage test?
And put some pics please
Greetings

I have a few questions which i hope you dont mind answering:-
1. How did you recondition the battery?
2. Does your kernel recognise the battery's full capacity or do you do a battery pull then it jumps back up significantly? Im facing this problem at the moment...
thank you in advance!
how long will the battery last for heavy use like playing 3d games?this is important as i use my phone for gaming most

1) I conditioning it by charging it overnight for 6-8 hours and then depleting it until it powers off (Actually, this is based on the instructions they gave in the parcel). I need to do it 5 times. Once done, I will be able to charge and stop charging when the indicator hits 100%. I basically use Battery Widget Pro (they have a feature called 'calibration'). Apparently, the battery itself states that it is 2,300mAh, but I think this is not accurate (hence the testing). You will know that the battery is fully charge when the indicator goes down to 0 (zero) mA (shows that the battery is not receiving any more charge).
2) Most cheap batteries have wrong indicators (e.g. temperature detection is not working, no indication of battery capacity). And yes, they suffer the need to 'pull the battery out first' before an additional amount is given. I bought one a while back, apparently one that has 3,000mAh. My observation is that the indicators are really gone. In fact, it will slowly go down to 50%, after which if you pull, it will give you 70%, once it goes down to 15%, it will last for a long while (30 minutes of browsing over 3G) before going down to 14%. Using that battery, I have been able to last 31 hours of moderate use (1 hour of music, 1 hour of gaming - not 3D, a few hours of browsing and a lot of photo taking). It costs only USD12 (thereabouts), which to me is the best deal yet. Down side of that battery is the very poor back battery cover. Using Battery Widget Pro (you have to charge fully and discharge until it shuts down and charge up again continuously), I got an estimated charge capacity of 1900mAh. Not bad don't you think?
The Mugen 2,600mAh easily matches my fake 3,000mAh one. The question is by how much. Sorry for the delay but my HD2 is my daily phone. So, I cant conduct full test like Engadget and other websites. But I'll do my best

Try Andida batteries. I had the 1600mAh one and it was slightly better than the original (giving me about 1300mAh). I had that a while back.
After much charging and recharging, I can confirm that the battery has about 2,200+mAh. See the attached images to see the estimated calculation using Battery Widget Pro.
Charging takes about 2 hours plus using the wall charger. The last 2% takes the longest.
As per request I ran 2 emulation apps (sorry, no 3d games), fpse & n64oid. The former ran Strider 2 while the latter ran Legend of Zelda: Ocarina of Time. Do note that I have overclocked my phone to 1.6ghz. All in all, it ran for 4.5 hours with 15% battery left. I'm pretty sure it could have clocked 5hours easily. I think that it is a good performance for 2.2kmAh battery don't you think? See the images below for a read of what other apps I was running. I managed to deplete the whole charge after nearly 10 hours of extremely heavy usage!
What do you guys think? Okay?

[Not the Mugen 2,600mAh Battery]
As an aside, I took and strip out the cheap battery which I bought for USD10, which claimed a 3000mAh, which only was about 2000mAh (+/- 200mAh) and took some photos of it. I can understand these extended batteries better. I am not an electronics person, but this would explain why it takes a restart to 'recognise' the 'remaining' battery on our devices.
Notice that they are basically two lower capacity batteries which are slapped together with the thin connectors and wrapped together with scotch tape.
I am not sure whether Mugen's the same, since it does not suffer from the 'restart-phone-to-get-additional-battery-reflected' scenario. However, I wonder whether there are any manufacturers who would just manufacture a genuine 2000mAh without merely slapping two products together (like in this picture). In light of this, it is much better to carry an external battery charger (anything more than 6,000mAh around!).
Anyone with electronic expertise want to comment on the pictures, please do.
Opps, forgot to add the photos of the battery and the battery cover which I mentioned. I find that after the first fall (yes, I tend to have accidents with my HD2 ... ) there is a slight creeking sound with the battery cover (nothing is chipped though). It is a rubberised battery cover, unlike the original metal cover. Still, the feel of the cover is great to the touch.
I am no longer using this device, but my dad is! It still works and have survived loads of damage... mostly dropping the device with the battery cover!
Hi, has anyone purchased / replaced their battery recently and could recommend a place to buy good quality battery. I have looked on e bay and all claim to be genuine, but some feed backs complain about battery not charging or losing charge fast.
Any help is appreciated
Bro, this phone is approximately 6yrs old. Hence there might not be any good battery like the original battery you re looking for. All you can find now is a battery that can do the job of a battery and not necessarily an original battery that can hold charges for hours.
I recently changed my battery. And this was the technique I used. However, more often than not, I use the packaging of the battery to determine its level of originality.
