...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)

Link to Mugen battery
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.

any news yet? I wan't to know the result

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?

Extended battery for original Droid?

Can the part MOTDRD2BATXW fit with the original Droid or should I stick to the Seidio slim battery instead?

I read that it does on a post. got to a verizon store and try it out. i have not personally tried either.
I saw a review that most of the aftermarket batteries fall short of claimed out put. buyer beware.

I am using a Droid 2 Extender battery in my Droid 1, and have been for months. I haven't noticed any issues yet, just keep in mind that you have to use the Droid 2 back cover (and it will be a tight fit).

Just have to use the extender battery door, because the extended battery (1850 mAh) is about 1.5 millimiters thicker.

what is its price?

So you use the extended on the droid 1. the battery fits but you have to use the droid 2 back? Will it still work in the dock and car dock? or does it stick out? also were did you buy it? thanks!

There are complete replacement sets on ebay including the needed battery door... and a bit more power: About 2300 mAH: http://cgi.ebay.com/Motorola-Droid-...624689435?pt=US_Batteries&hash=item2a0e12091b

a user on our german android forums (android-hilfe.de) had conducted a series of tests on these "extended" batteries and has (to sum it up) proven them to be pretty much pointless. the mAh value printed on is a lie to say the least, and the added bulk and need for a new battery cover drives the price up to a point where you´d simply be better off (cheaper and in terms of battery life) with an additional "normal" battery.
would explain why there seems to be virtually NOBODY that is using these extended hulks of a battery ^^

I think an original BP7X motorola battery can really boost the duration...

I use extended batteries constantly on my CDMA HTC Hero200 and on my Moto Droid 1. They last a great deal longer and yes they do make the phones look like a brick but it makes up for it in the time the phone can stay on longer. I'm in the military and my Hero stays on for 2-3 days without needing a recharge if I'm not constantly messing with it. If I'm actively doing things with the phone it draws more power. Also if you leave the GPS and Wi-Fi on it draws more power. Everything makes a difference. Close all apps you don't need running and shut down anything not needed for longer battery life. Overall,for 10 dollars on EBay you can't beat it,I'll make that user on the German Android Forums look like a chump when it comes to batteries.

I bought the extended battery a few weeks after getting my D3. Typically, I get more than 24 hours to a charge. That's with quite a bit of texting, phone calls and surfing. The battery comes with a new back cover for the phone.

You can find one here particularly for milestone 3300mAh [HLI-A855XL]
http://www.mugen-power-batteries.co...-milestone-with-battery-in-black-3300mah.html

With the BP7X battery being around 1 to 1.5mm thicker can you just remove the sticky sponge pad on the back of the Droid/Milestone battery panel? I'm hoping that works as the pad itself is around 1mm thick and is there to fill a recess and push against the battery.

[FAQ] Extended Battery is not Recognized correctly (discharging like the original)

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....
Mikeanywhere

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?

Highest capacity of battery

Hi all,
I would like to buy a same size as ori battery with highest capacity available in the market now..
Anyone know where could I get it? What is the battery capacity? And lastly what is the price range? Thanks ya.. I'm searching for it as i donwan to charge my phone twice a day.. quite irritating..
Sent from my HTC Incredible S using Tapatalk

there are a few ebay sellers who sell the genuine htc battery. just search for "genuine htc ba s520" on ebay. most are based in uk. all around 15 - 20 gbp.
you will find several chinese aftermarket batteries claiming higher capacity than the 1450mah of the genuine battery, but beware. none of them (i've tested a few) actually last longer than the htc battery, in my experience. and i don't know if the quality can be trusted. they do cost a lot less than the genuine battery so it is a cheaper option.

u can try dc mugen

I want higher capacity battery so that my phone last longer between charging.. not HTC ori battery with same capacity.. thanks ya..

If it would be possible to put more capacity in the same size battery HTC would have done that from the start, you're only option is to get one of those fat 3500mah batteries from ebay with a thicker battery cover, i'm thinking of getting one of those, unfortunatly i can't put a silicon case around the phone then ...

is anyone aware which is better battery among the custom makers ?
Will be great if that is available in India .

4000mAh Battery
Just bought one of those chinese 4000 mAh batteries on ebay.
The [email protected]#$%^ thing won't let me switch on mobile network (3G) ?????????!!
Real Handy.......wifi, bluetooth, gps all fine.
It may be an HTC issue, like Windows, doesn't like hardware changes, it may be the rear case,who knows?
It's a thumping big thing, twice the size, but I only get about another half a day.....Whooopeee.
Thankfully it was only about five bucks.
Anyone have a similar issue ?

SEIDIO SUPER EXTENDED LIFE BATTERY FOR HTC INCREDIBLE S

extended battery/door
Thanks mate, I'll take a look.

I've been using the previously mentioned Mugen 3700 mA extended battery (larger, yes, but I'm used to it already) for 2.5 weeks now.
I've completed calibrating and conditioning the battery thru the 5 discharge cycles as instructed, followed by some of the lore I've sifted from xda. It's been useful.
I used to charge in morning and had to be careful not to use my phone too much and need to charge again in one day if I used it a fair amount. My incS was used, so stock battery probably had wear.
Now I get two full days of moderate-somewhat heavy use, and very far into the 3rd day if I use it just for (many) texts and a few short calls and it sleeps half the time or more.
E.g., charged before bed, sat unplugged during sleep, heavy use today (gps for 30+ min, browsing, texts) and 71% capacity as of now.

Good try! how much it cost?

That's meant so far no identical battery with longer battery life (i.e. last 1 whole day for moderate to heavy use)? sigh...

Stick to genuine HTC batteries. Most of the Ebay fakes are far lower quality and often are mislabeled (especially if it claims higher capacity in the same form factor).
Your phone should last at least 24 hours on one charge though (unless you're using it very heavily). Try changing your habits a bit (turning off data/wifi when not using it) and also maybe try a battery calibration. If you do a battery calibration make sure you read a few guides on google and do it properly otherwise you will most likely be worse off.

Some aftermarket hi capacity battery need a special battery cover which makes it very ugly

I bought the 3500 mAh battery with fat back cover (from Ebay). Its a chinese ****s production... We know that on our IncS the antenna is placed inside of back cover. This chinese cover has some antenna as well, but the signal is much worse. For example with original cover I get like 4 full bars. With chinese ****s cover I get only 2-3 bars.
Im already having troubles with the signal in some places, but with this cover it will be even worse.. So I stay with my original HTC back cover. Dunno what to do with this 3500 battery..

why don't you buy another stock battery ?
i think stock one is gd enough.

I think that MUGEN 3600mAh is optimal high-capacity battery on the market. Its stable and reliable...

Has any1 tried using Seidio batteries for Incredible S?
Apparently, they claim to use Lithium Polymer technology as opposed to Lithium-ion.
Wikipedia says Polymer is superior to ion but also more expensive.
Only mobile manufacturer known to supply phones with Lithium Polymer batteries is Sony Ericsson.
Seido 3500mAH battery for HTC Incredible S is on eBay for $69. It says its assembled in Taiwan? Its also not as FAT as Mugen's but still needs a back door, which is included. They also have a website.
Mugen might have a new, superior competitor.

Review Mugen Power 3900mAh Extended Battery

SKU: HLI-NexusSXL
Cell Type: Li-ION
Voltage: 3.7v
Capacity (mAh): 3900
Battery Door: Included
Original Battery Model: AB653850CA (1500 mAh)
Product: Mugen Power 3900mAh Extended Battery for Google Samsung Nexus S / T-Mobile Nexus S with Battery Door
Rom used: my own kwbr rom
Kernel: stock kernel ICS 4.1.1 (3.0.31-g3b0c5d2)
For all that are interested in an extended battery for the Nexus S here is a small review of the 3900mAh extended Mugen battery.
Unpacking and installing
The Mugen 3900mAh for the Nexus S came in the known package including quick start guide how to calibrate the battery. Shipped the day after ordering it arrived within 2 weeks. First thing you will notice is the size of the battery as well as the battery door. These are quite huge.
The 3900mAh battery has a perfect fit although I had to use some pressure the first time installing the battery. Battery door installed without any problems.
Using the battery
Although the backcover is pretty huge, making the Nexus S really a bulky phone, strange thing is it gives a great grip. So, let's clear battery stats after installing the hardware. After a week of usage I can say the battery is great. I can run this device for days! Check images for stats and info.
The Verdict
A very good battery although not cheap. No need to charge the phone on a daily basis instead of the stock battery. In the end I think I will only use this battery when on holidays. It will give you a brilliant battery life ... but it also completely changes the way the Nexus S feels. And that's one thing I like about this device. Conclusion in the end is it highly depends on personal taste and real need for a bigger battery. More juice you will get for sure!

FYI to drop a bit on the price, if you buy from Mugen official website, they offer a facebook discount. And their customer support is also very good quality. And i think all together this battery is worth every penny, it is a very good accessory indeed.

Thanks for the review, does NFC (Beam) still work with the extended battery cover?
