Speaking as someone who uses their phone pretty darn constantly, I'm in need of a battery that lasts a bit longer than the stock.
currently, Seidio is selling an extended battery (I would link, but as a noob I'm not able to..) 1750 mAh - no new door required, but only a gain of 450 mAh..
Verizon has stated there's a 2150 mAh extended battery coming, but that will almost certainly require a new back plate.
Anyone spotted any other compatible batteries yet?
I ordered the Seidio one and while it fits behind the stock cover it also adds a bit of weight, which is great considering how light this bad boy is.
Seidio is also going to release a 3500 mAh battery in the near future! According to their website, it adds 3-5 mm of width. But for the extra battery I think it will be worth it. The only problem is I am debating on purchasing this because I had one for my tilt and well it flat out sucked after a month of use.
what do you mean it flat out sucked after a month, the thickness or the capacity of the battery?
The battery itself would barley last a day if I was lucky. Seidio just said it needed to charge like 8 times before it was full. It didn't kick in. Is this rare?

Did you let it fully drain till the phone died, and keep turning the phone on until it wont turn on anymore. Then charge it fully, unplug when it is fully charged, let it get back down to 90-95%, then fully charge again, let die & repeat. Do that a few times and your battery life should be better. This is what I do whenever I get a new phone...
We use LiION Batteries, No special charging required
OK, to start, there is NO NEED to do any special charging conditions with Li Ion batteries, it does not matter how they are charged. A standard battery will have between 400 and 1200 charge cycles before it loses 50% of its capacity (1200 if you charge at 50%, 400 if you charge at 0-10%, like when the phone quits on you). Ni Cadmium on the other hand does require special charging situations but we don't use them in cell phones because of the mass. You can do take the advice of the previous post, but if you do that I would suggest sacrificing a virgin symbian phone or doing a handstand while plugging in your phone to charge. That might increase the battery life too.
Secondly, I spoke with Verizon, and their 2100 mA extended battery will be available soon and it is supposed to fit with the stock backing, probably the best way to go if you ask me, only $60 too. I am checking their site almost daily waiting for this to become available since like many, I need more battery life, I find that I can barely make it through the day without being conservative with the use, and that's on a work day when I'm not on it that much, on the weekends I have to charge it in the afternoon.
If you want to save on battery, turn down the screen brightness, chose a background with as few colors as possible, the more black the less battery you will use since its an AMOLED, blacks mean there is no power being used on the screen. Turn off your GEO locations services both on the phone settings and in programs that run a lot. This will easily save you 25-30% battery life.

I was at a Verizon store yesterday asking about it and they showed me their documentation. Their extended battery will come with a new back cover that is slightly raised to fit the larger battery.
I'm waiting for this too because it looks like it will be the most aesthetically pleasing option.
Too bad the guy had NO idea when the accessories were going to become available. Ugh.

Verizon doesn't trust their employees very much - to prevent leaks, they don't tell people about equipment/accessory release dates til within about two weeks of the actual release. The Incredible launch announcement had one of the longest announcement to release times I've seen the the last two years.

$14.99 + free shipping for a battery that lasts all day from moderate use? This sounds great and I'm ready to buy it now! ... But is it safe to use this battery with an Incredible?

I dont know, but my seideco 1750 def gets me 3 more hours a day on my Incredible. I have switched back and forth from stock and the extended...the extended wins EVERYTIME...so Im not sure about that report.
@ suzook
I read that my OEM TP2 rated as one of the best.
TP2 OEM standard issue Rated @ 1500mAh Tested @ 1414mAh
Most Likely our stock incredible battery has a lower mAh then it actually states it is.
@ Xxq TZ pxX
Yes it will work because its in my phone now working like a champ ;O)
I also told someone else here like myself who swapped from the tp2 ====> incredible and he seen it first hand as-well.
TP2 batteries work fine
Hey all,
The TP2 battery works fine. Same size and 200mAh more than stock... in fact I've seen them sold on Fommy.com as the thin extended battery for $44.95. Don't be fooled, and just go buy the TP2 batteries. They're cheaper if you don't need the therapy session of a rebranding.
Enjoy!
P.S. Got a workaround for Skype too...
I'm sure a number of HTC CDMA phones have interchangeable batteries.
I swapped out the 1500mAh battery from my Sprint Hero and put it into my Incredible. It's easily out lasting the stock incredible battery.
I ordered the 1500 HTC battery as well. Between those to staying charged I am not worried about it.
Also anyone know of a battery charger for these types of batteries?
For those of you that want a red 1500mah battery I found this but im not sure if its oem or not it just says its an htc extra capacity battery hxxp://shop.htcpedia.com/index.php?dispatch=products.view&product_id=825

...sounds definitely interesting! It seems to be a company in Hong Kong. Are the $46.95 quoted therefore HK Dollar? ;-)
Any first-hand experience?
ill wait till i see some real life reviews before i get one of these but it sounds promising!
I have mine on order now. Upgrading to a 1500mah battery made a decent difference in usabillity, hoping for the same difference again in a step up to 1800mah.
Should get two days battery life out of it then between charges
Friend..Do not forget to post your experience in Detail.
Your experience will make 100's other crying people happy or sad....(they will decide whether to buy this or not)

There's a link for this battery, but I can't post it because I'm a new user, just google Mugen.
I'm considering buying this for my T-Mobile/HTC MyTouch 3G Slide, if it's any good. I'd like to find a dock to charge this battery! If anyone finds one, let me know.

Did you get the battery, or is it still on its way?
Edit: Someone on a Dutch forum has this battery and will report in a few days. I will post his findings here!
First review from a Dutch forum (translated from Dutch, so it might be a little iffy):
I've got the Mugen Power Extended Battery for HTC 1800mAh Legend BB00100 a few days now. Enough time (following the instructions) to fully charge and empty the battery a few times. I drained the battery by leaving the phone running Google Maps navigation. Yesterday and today was the first normal use.
Old situation: Before I had this battery, I was happy if the battery could make it through one working day. With light use in the morning, and in the evening with 40-50% left to do some web browsing. If I didn't put it on the charger at night, the next morning it was about 15%, not enough to start the day. Under normal to heavy use I never made it to the end of the day without charging in between.
New situation: With the same kind of usage it's about 70% in the evening. Again some web browsing before bed and no charger. This morning there was still 43%.
Conclusion: I still put it on the charger because I'm still unlikely to make it through an entire day. But what's clear is that I can make it easily through one day even with heavier use, no more charging in between. That makes the purchase worth for me.
Don't expect that you now can navigate for hours without draining your battery because that won't change. That was exactly what I hoped it would cause. Nothing more annoying than a device to with normal to heavy use that won't make it through one day. Striking is that the Battery Graph program (from where I get these measurements) shows that this battery longer stays at 100% and about as steep downhill runs compared to the standard battery.
so, to resume... even with the 1800mah battery, heavy use will make legend go for just one day...lol
this is intriguing to me...
how in the heck can a Samsung Galaxy Spica GT-I5700, with android 2.1 (there is an update for it now) last about 3 days with normal-heavy use, with the original battery of only 1500mah?!?!?!?! something is very wrong with Legend power usage...
PS. I've seen with my own eyes what I've said about the Samsung...
Yeah, I know it's strange.. Maybe the rom cookers can find out what's causing the power issue.
that would be nice, but I don't know what is the technical skills required to find out...
I can use the battery for 2 to 3days with browsing and some navigation (and 3G is always on, GPS only when needed). BUT: I use taskpanel lite too autokill most programs on standby, really made much difference for me

The reviewer from the Dutch forum said that the battery does what it stands for.. So it will add about 30% battery life and it will hold up better under heavy use.

Hi,
What about the size of the Mugen Power Extended 1800mAh Battery? Is it the same size as the original 1300mAh one? If not, how much bigger it is? Any photos?
On Mugen website it says:
"The extra size and weight increases pale into insignificance when you consider the true convenience the battery gives... it represents excellent value for money."
Thanks!

For the legend, the battery is the same size as the original (it has to be, since you can't remove the entire back of the phone and replace it with a larger back).
Weight? Not sure if it will be much heavier than the original.
I ordered mine and it's on the way, but it could takes weeks to get in
Mine is also on the way, and I was thinking about doing a mini-review of it. Not done like the other one here, but with the method mention earlier here: With the screen at maximum brightness and video running running and see who lasts the longest. Any other method? Maybe with a benchmark-tool standing at repeat, if there are any?
Suggestions?
the forum here is full with problems of people who did get a cheap chinese battery from ebay or somewhere else, that is not recognized by their htc hd2 and is discharging at the rate of the shipped original small battery.
also the forum is full with "solutions" that are NOT WORKING that WILL NEVER WORK.
this is the reason for this thread to give the people the one and only answer to fix their problem!
first of all, be sure to have the newest firmware to have the extended battery driver.
but this will only solve charging problems if you got one of the first shipped firmwares.
after that get the ORIGINAL EXTENDED BATTERY. also the 2300mah battery from the company "leicke" is working for me. (looks identical to the original extended battery, maybe its the same)
this batteries will be recognized correctly and will discharge in the right speed!
--- got a chinese "noname" battery? ---
your battery is crap like most other extended batterys for hd2. get another one, but continue reading the rest of this thread before!
i had a cheap 2400mah chinese battery before and had the same problem.
the thing is, that these chinese batteries are faking, they are normal ones because the driver of the hd2 origininally didnt support bigger batterys in the first roms.
the chinese batterys are out of date (they only added a kickstandcover) and also the capacity is mostly a giant fake!
i disassembled my chinese cameron sino battery and here is the result: its made of 2 small batteries pakaged in one frame and controlled with one chip that is sending fakedata to the phone, also the temperature is recognized wrong because it doesn't really have a sensor! it always shows 25,X°C all the time. like i said: totally faked data
tip but not a solution: if you discharge your chinese battery to 0%, remove it and put it back into the device, you should have 50% again, but thats no calibration because a calibration of this batteries is not possible!
my "leicke" battery did cost 21 euro incl shipping and is working correctly, also the high quality cover with metal-kickstand is fitting perfectly, not like the chinese ones that never fits!
dont try to fix the problem with hints and tricks or calibrations, it will NOT AND NEVER work with the cheap crappy chinese batteries! i already tested it!
i hope this thread is helping the most people with their cheap-battery-problems.
thanks for reading
Cheers for the info,,,, really was dissapointed with the cheapo one i got the other day..... Could you provide a link for the leicke battery?
~Many thanks in advance....

here is the link of my battery: http://www.amazon.de/LEICKE®-Akku-7VDC-2300mAh-Akkufachdeckel/dp/B0043DOCFE
working 100%
i paid 20.99,- euro 3 weeks ago included shipping inside of germany. current price is 15,- euro without shipping
thanks very much! on order now...
How long does the Leicke battery last by you ?? By me not too long , just a littel more than the original -.-
for me it lasts with wlan on and permanent internet using ca 10-12 hours (and still is not empty). in standby-mode many days and maybe weeks with windows mobile. (under 5-10% draining a day with phone on)
it lasts nearly the double time of the original battery. i can tell you, that the 2300mah are the real capacity and how long your battery lasts depends on your systemsettings, phoneusage etc.
i use battclock to control the current powerdraining. with wlan on it is ca 140-300mah but mostly a little bit under 200mah. so you can calculate yourself how long the battery lasts until it is empty
I'm using the licked battery too and can confirm that it works correctly with the hd2. With current android builds the battery last for 3 days with moderate use. If you can live with the bulky shape, the leicke is definitely a great alternative to the official HTC extended battery. Cover and stand are also quite ok, aluminium cover would be nicer but can surely not be expected at such a low price.

I use the cheap China batterry 2400hr
I bought off ebay for $14.00 US shipped and it works perfectly. The back cover fits like it was made for it. Snaps on cleanly and has never come off or stick up on the edges. The battery charges with Android and WinnMo to 100% and lasts for days. Most of your charging problems may be your rom or radio version. There are probably multiple makers in China so some may be better than others. My Cheap China works works okydoky!
can you share the companyname and capacity of your battery? many people are interested in that
Here is the current link.
It has gone up a little bit. Just bid on it to get the cheaper price. There are several in his store. I got mine several months ago. Just buy a cheap silicone case and cut a hole for the cover to stick through on the back. Works good and looks fine. Only HD2 snobs will know any difference!
http://cgi.ebay.com/2400mAh-Extende...211159?pt=PDA_Accessories&hash=item4cf386c897
Just bought the Leicke too.
Unfortunately it does not charge at all in WinMO
I use an NRG rom.
It seemed to work in Android but it went really fast downhill at 50% at 7% or so it was at 3.9 Volts which is rather high to be at that %.
maybe your rom don't support extended batterys. try another one like the oem rom from htc and test it.
the first roms didn't charge real extended batterys.
and you need the right android kernel for extended batterys because many kernels are buggy,
i use the kernel of froyo sense 2.4 and its working perfectly
Which WinMo rom are you using Schildzilla?
i am using a german rom called "EPS V5" - it is only a little tweaked oem rom with the newest drivers
thanx a lot.. i'm gonna update the kernel
Its nothing to do with the battery , its the android os and he kernel which is main cause of the battery not getting detected where the manufacturers are putting in the code which only detects the stock battery and thus your extended battery reports and drains like the normal battery.
I have a mugen 4800 for my dell streak and because of dell's coding my battery is not getting detected on froyo and on gingerbread, however it is getting detected properly on android 1.5 and 1.6 so its nothing to do with the battery. I agree to your point regarding the kernels having the extended battery support and that is the main cause for this reporting error.
Thanks! Great info mate
Leicke Extended battery only charges when switched off
I've just bought the extended Leicke battery (from Amazon @ £15.)
When plugged into either my laptop or to the mains adapter I get orange and green alternating blinking lights and it doesn't charge. When the phone is off, the light is constant orange and charges.
I have the standard WWE ROM 3.14.405.2 and have just reapplied the same ROM in case I've done something to cause the problem.
This FAQ seems to confirm that the battery won't charge when the HD2 is on as a result of something that HTC have put into the Kernel to try and make sure that we only buy HTC branded batteries. It seems that I will need to go to a custom version, although I may just leave it off over night when charging.
Thanks.
Hi guys,
Got an HTC extended battery. Not recognized by my hd2 running Pdaimatejam WP7 ROM Ver-7.1. I have read though many threads on XDA, but no solution !
After charging in magldr mode for 10 hrs it shows only 55 %. And the battery tool by HTC only shows capacity as 1230 , while the actual capacity is 2300.
Can any one guide me to a wp7 rom which will recognize the extended battery.
Sent from my HD7 T9292 using XDA Windows Phone 7 App
I would also need some help, the "stock" MIUI ROM doesn´t recognize the Leicke extended Battery...
Could someone please help me with all this Kernel stuff etc. I´ve read a lot but I don´t know what special Kernel is compatible with what ROM...
EDIT: Is it an alternative to just buy an externel battery dock so that you could just switch the battery if it´s empty?
New Extended Battery "possibly" 3'500 mAh + External Charger - "Update 10.16.2011"
Just recieved my new extended battery with extended back door for my Milestone 1. Bought it from here:
www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=180686832371&ssPageName=ADME:L:OC:CH:1123
It took a good month to arrive from china to europe, but it's finally here.
It weighs 47 gramms vs 27 gr for the standard BP6X and is twice as thick.
Can't say much about the accuracy of the amperage as I just fully recharged it with the external charger I ordered from here:
www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=250859367106&ssPageName=ADME:L:OC:CH:1123
As you can see it's quite cheap and although ordered on the same day as the battery, it arrived 3 weeks before..! (About 10 days after my order). It's working very good and sports also a usb port (5.2 Volts and 800 mA output) at the end for standard charging. I haven't tried yet which of the battery or the device will be charged first, though. Will report about it later.
I'll also report about real life battery time in a few days, after testing.
I'm still very happy with my good ol' milestone 1 (european droid 1), and although it's a little short on memory, latest CM 7.1 developpements make it very fast and usable.
Edit: Just tried to charge through the usb port of the charger, it doesn't work. I guess 800 mA is not enough, had the same issue with other car/home chargers. I think motorola's ones have 1A output. Even my Galaxy Tab's isn't powerfull enough... What a Milestone Beast!
Edit 2: Battery has reach 10% after 31 hours of standard use. As I though, real intensity most be around 2800 mAh and not 3500 mAh as stated. But it's still around 2x what we can expect from the original one. I run my Milestone on CM7.1 ROM and 1800MHz network.
Edit 3: I'm experiencing the "1% battery left" effect of some other devices' extended batteries for about 9 hours now! So until now It's been working for more than 40h. I tried to switch the phone of and back on again, but still 1% left and red led blinking (on some devices it makes it measure the value of the second cell, I guess, and brings it back to about 90%. Don't ask me why... It happens on my Dell Streak 5). I hadn't had this with my Xperia X10, where the energy left of my extended battery was accurate.
Final edit: worked for a good 48 hours. I must add that I put my phone during night time in Airplane mode (about 16 hours, but with some wifi surfing).

which charger do u use for charging the new battery through ur device's standardnusb port?
I charged it first with the external charger, as I think it's the best way to be sure that the whole battery is thouroughly and fully charged. But since first charge I also recharged it through the device's microusb port, which seems to work fine.
Since my first post, I also recieved my second extended battery:
www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=190572457987&ssPageName=ADME:L:OC:CH:1123
It looks almost the same as the first one, except the font used on the sticker is smaller and the price is cheaper.
I'm testing its power time right now, expecting it to be close to the one of its siebling.
I had also ordered a standard sized 1870 mAh battery from here:
www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=150585920125&ssPageName=ADME:L:OC:CH:1123
Problem with this one is it doesn't show battery status on the phone, as the mAh level can't be determinated by the phone. Will check with the seller what can be done (problem only with my battery?)
I saw another standard 1800 mAh battery for sale ($ 10.-), maybe will give it a try, seller seems more serious.

Some updates about my second extended battery: I now have had a full discharging/charging cycle (in the phone itself) and it seems that the battery is now calibrated. My updated "Battery Monitor Widget" shows me now 2885 mAh for the full capacity and the phone gives apparently the right power status. Real life use time seems the same as my first extended battery, about 48 hours.

How can you even put your Milestone in your pocket?? The battery door looks HUGE
Right now I'm using this battery:
http://www.ebay.co.uk/itm/ws/eBayISAPI.dll?ViewItem&item=130579480018&ssPageName=ADME:L:OC:GB:1123
it has cca 80% of the original battery capacity, however it is much better then the other chinese battery I've owned in milestone, (I think) it supports the 1% mod, and it did cost me $1.89 delivered to my place.
I always take the old original battery and the dying chinese battery in my bag in case this new dies. I will get probably the same power-on hours count as with this extended battery yet with smaller package.
I just order one like this... thank's for the review

Yes, please do post some updates and reviews.
I am only aware of 3300mAh [HLI-A855XL] by Mugen for Motorola Milestone which have good reviews.
it works fine
I have flashed my Att I897 with RemICS JB rom, and then I ran the battery dead. Then I fully charged it and it doesn't last 5 hrs now. I even calibrated the battery. Any ideas, or is this normal with custon rom?
Have you tried any other roms? Download a battery stat app let it run a few days and see what's using up all of the battery. Did this happen prior to flashing or no?

I have been running this rom for a few weeks, with no issues. Then went out and bought a new phone, and my brother needed one so I gave my I897 to him . I reflashed it, to clean everything up and let him put on the apps he wanted. And the battery does with in 4-6 hrs. I will d/l the stat app and see where is goes.
I have another I897 runnig the same rom, on my daughters phone, and it has great battery life still.
added thoughts
if your brother is making heavy use of the phone, with screen on much of the time, then 4 to 6 hours is normal.
running the batt dead once shouldn't kill it. there are protections in pm chip to stop before batt voltage gets too low.
aging, as in several hundreds of charge cycles, will reduce batt capacity to half or less of original capacity.

oh, and swapping the batteries between the two phones and running a few days will tell if battery age is the problem.
I'd say it's time for a new battery. 2y old battery has significantly reduced capacity. I'm using original Samsung Epic 4G Touch SPH-D710 1800mAh battery, fits well in Captivate with stock cover. Battery life is very good for a smart phone. Stand-by >48h easily, holds >18h with about 2h talk + 3-4h screen on. Currently on SlimBean 2.5 ROM. Search eBay, it's about $15 only. Avoid cheap noname 1800mAh (or even more "on paper") Chinese batteries, usually the real capacity is well below claimed capacity.

I was getting a good 10 hrs on it till I reflashed it this last time. I had great battery life with that little phone. That includes texting and FB'ing talking
I have 2 more and I still get great battery life.
I've never tried RemICS JB but I'm in doubt the ROM itself is causing battery drain. I'm getting almost same battery live with CM10 Stable, PAC-ROM, SaltyBean SE, SlimBean. Currently running SlimBean. Make sure it's not an app you install after flashing the ROM. Never restore system data from your previous ROM, just user apps + data. Look at the battery panel and you'll see what is draining your battery. Btw, clearing battery stats does nothing. You can't really calibrate the battery. Android OS will adjust battery meter automatically after 2-3 recharges.

Yeah. I found out one prob was he was trying to charge it with just hooking it up to a pc. Know it seems back to normal since he used the wall charger, for a overnight charge
I've charged from the PC many times with decent battery life results... Don't know if that's the reason why the battery life has been cut short.
A good way to gauge what is causing the battery drain would be to do as ValD said. See what is using up the most battery life from the battery panel and try to deduce it from there.
Have you tried full wipe, re-d/l the ROM, and flashing the ROM again? Double check the md5 or sha1 code from the website when you d/l the ROM too.

yeah, some PC only provide max 100ma per port, which means ~ 15 hrs. and the cap in phone for usb is set to 350ma, or about 5 hours, unless you have kernel that supports fast usb charging.
still, if the phone was charged to 100%, it shouldn't matter whether AC charger or PC used. Was he not charging it to 100% ?
fyi, the difference to phone is that pins 2 and 3 of usb are shorted in AC charger. This causes phone to allow higher charging current, up to 900ma, or as much as battery can take without overheating.
