Mugen have told us there is aproblem with some battery's. They should replace it for you.

I'm waiting for my replacement still.
[Desire Accessories] Diamond360:
I have already waited several week before getting this battery... If I have to exchange it, ... i will take an eternity to have a new one back!!!!
[Desire Accessories] paprkut:
Only way to do it is by getting in touch with mugen
[Desire Accessories] Diamond360:
Thank. I just contact them... Hope they will find a rapid solution...
[Desire Accessories] asuradahk:
hey ,

May I ask something here,

people keep saying the Mugen 3200mah battery is faulty and device off prematurely.

just wonder how long can these faulty batteries stand for with fair usage or heavy usage?

phone dies at 20% after 1 or 2 days heavy usage?

really so tempted to get one now! OMG

hate the official battery so much, even with setcpu underclocking my Desire is still so hungry all the time.
[Desire Accessories] paprkut:
With heavy wifi net use around 1.75 days. That's with texting a lot.

If you hardly use it and have all the default settings on. Ie auto brightness. Then in a day I use up about 15-20%

The good thing is you know it will last a day atleast with heavy use and you wont have to charge up until atleast the evening or when you sleep.
[Desire Accessories] karazz:
I received it, installed it and walked around with it for 1 day. The battery was fully charged but I haven't noticed a real difference. The larger and heavier phone is more annoying than it is useful. With the new battery the phone still has to go on the charger each day...

So I'm back to the stock battery and my smaller and lighter phone... :)
[Desire Accessories] goofy584:
I use it since 2 month now and it works! Between 3-4 days with Wifi, Gmail, Exchange ...

:D
[Desire Accessories] goofy584:
you have to uncharge and recharge the battery 5-6 times to get the full power!

use the phone to 5%, shutdown, charge full ....
[Desire Accessories] paprkut:
That's of it doesn't switch off at 25%
[Desire Accessories] karazz:
Does it make a big difference?

But I will try and let you know...
[Desire Accessories] paprkut:
Well after mugen told me I'd get my replacement battery by the end of the month it seem s they have not even shipped it out yet
[Desire Accessories] asuradahk:
hey,

i got a reply from them as follow

Thank you for your email!

We send back all the Desire's battery to factory, they might destroy the old stock,

The factory will make the new good working stock at the moment,

they will send us the stock after test, so the next stock must be all right.

The next shipment would start on 31 Aug.

Please contact me if you need any additional info.

Best Regards,

I purchased two 1600mah mugen and tried in two desires with same test settings etc and have seen next to no improvement over the standard HTC battery. On paper they appear to have more mah but in testing ive seen as little as 2% increase?

How does the 3200 fair as on paper again it looks impressive but do the results match the spec?
[Desire Accessories] paprkut:
Probably the same as two 1600mah.
[Desire Accessories] goofy584:
Mugen 3200

I got one of the first 3200 mah batterys from Mugen and after several uncharging - total recharge cycles my battery works REALLY FINE! With "normal" use (Wifi, sync of Gmail and Exchange (every 2hours), some Internet, Games ...) I have to charge after 3 days.

;)

[Desire Accessories] DrHRH:
I disagree about larger and heavier being annoying. In my case the fact that the battery sticks out means that the phone is much easier to hold and less likely to slip out of my hand (something which happened with the stock battery). I must say that the difference in weight is hardly noticeable in my opinion.
[Desire Accessories] paprkut:
Hrh any Luck? Mugen haven't sent out the battery yet.
[Desire Accessories] DrHRH:
Had a reply on Monday 30th saying it would be sent out the following day and to expect it in 5-10 days. So a bit more patience is needed I spose.
[Desire Accessories] paprkut:
They told me they would send out tracking details on Monday. Here's hoping they do.
[Desire Accessories] wanted008:
Hi all,

I placed a advanced order for the mugen HTC desire 3200 mah battery and was told it would be shipped out on 26th august and I would be provided a tracking number.

Well 26th august passed by and no news of my tracking number so i contacted mugen customer service and got this reply.

--please do not reply below this line--

Dear sir,

Thank you for your email!

Sorry for the delay again, the shipment will be on 31 Aug.

our desire's battery need to double check the quality,

make sure we won't send the fault battery to customer.

Please contact me if you need any additional info.

Best Regards,

Jan

The 31st of august passed by no news on my tracking number. I was really frustrated by this time so I contacted them again and got a reply back saying that I would get tracking number later that day but I never did.

I was really mad now I emailed them on 1st of august and had to email them three times to get a reply back and finaly got this reply back.

--please do not reply below this line--

Dear sir,

Thank you for your email!

This was some technology problem in factory,

the battery doesn't work after test, so we make the new one,

we don't want our customer received any fault battery from us,

sorry about the delay.

Please contact me if you need any additional info.

Best Regards,

Jan

https://www.mugen-power-batteries.com

And I was promised in another email that it would ship out on1st august but it never did. So I finally gave up and requested a refund.then I got this reply back.

--please do not reply below this line--

Dear sir,

Thank you for your email and sorry for delay!

We had to do final tests with new batteries as we had received some reports of desire xl batteries not working as expected. All the batteries are tested now and ready to be shipped on Tuesday.

Please confirm.

Please contact me if you need any additional info.

Best Regards,

Nikolai

https://www.mugen-power-batteries.com

So I finally got my refund back the customer service here was awfull. They should have tested everything before accepting orders. Not good from a reliable seller? If any does receive there battery from here ever please let me know how the battery does. Thanks
[Desire Accessories] paprkut:
Dude. I'm sure you would be more pissed off if they had sent you a faulty battery and then told you to return it before they gave you a working one.
[Desire Accessories] wanted008:
I think i will wait till there batterys ready to buy. Then I will purchase it.
[Desire Accessories] paprkut:
i think someone reviewed that battery earlier on in this thread.

by the way mugen have sent me a email saying the batterys been dispatched, heres hoping they actually did test them before dispatch
[Desire Accessories] nodiaque:
what about all those battery on ebay? doesn't that suit anyone?

there's also dealextreme that got a 2600mah one

details.dx/sku.41891

sorry cannot post link
[Desire Accessories] wanted008:
I would not recommend the ones from eBay as they are not compliant ce standards.

And if buy the ones off eBay it might just blow up in your face after you put in mobile.
[Desire Accessories] DrHRH:
I agree and disagree at the same time. Yes, it's true that there are some unscrupulous sellers who would offer potentially dangerous untested batteries. However, there are also plenty of genuine people selling genuine goods. I bought an extended battery for my Hero from eBay and it was amazing. The seller was based in the UK.

I recommend caution when buying from a seller based in the Far East. Thoroughly check the feedback and sales history, but don't rule everything out just because it's on eBay.
[Desire Accessories] wanted008:
As long as your buying in to a Europe country and the item is genuinely Ce certified then it should be alright to purchase from a reliable seller with good feedback.

But I strongly don't recommend buying any battery without Ce approval in Europe from any where which is not Ce certefied.

[Desire Accessories] Mikeyy:
Anyone tryed one of these 1600mah batteries? Any comments?

http://cgi.ebay.com/1600mAh-BATTERY...500813?pt=PDA_Accessories&hash=item483c4fb08d

or

http://shop.ebay.com/i.html?_nkw=ba...re+1600&_osacat=0&_trksid=p3286.c0.m270.l1313

Does it last longer then original 1400mah?
[Desire Accessories] paprkut:
Why bother? You will get an extra 3 hours or so if yourlucky
[Desire Accessories] Mikeyy:
Why not? 3 hours is better then nothing. Just interested if someone already bought it and tested it?
[Desire Accessories] whoosh71:
I have been reading and following this thread for a while since I purchased the 3200mA battery from Mugen as well. Unfortunatly it had the problem other people described in here; it lost all power at 25%.

Anyways; as Mugen was able to identify the problem and revised some parts, I mailed them last week and they sent me a replacement on Monday. It arrived today, it's still on the charger, but Im pretty sure it'll be okay.

Here's the good thing; replacement was free of charge (which isnt special; since the original unit had a defect) but they included their belt holster with a protective cover as well! That's pretty good service in my book :)

Even with the battery not working right I was getting a few days worth of useage out of it, so this should only get better as it has another 25% worth of juice to play with.
[Desire Accessories] DrHRH:
Look at batteryboss.org. I don't think these 1600 batteries are any better than standard. In some cases they've actually turned out to be worse than the original.
[Desire Accessories] DrHRH:
When did you contact them and how long did you have to wait for your replacement? Mine hasn't arrived yet despite an email saying it would be sent out on Sep 1st. They said 5-10 days. I'm hoping it'll get here tomorrow.
[Desire Accessories] whoosh71:
I've contacted them on Sept. 3 and they shipped out the replacement on Sept. 6 by regular airmail from Hongkong. It arrived yesterday, on Sept. 11.

Funny thing is; this was regular registered airmail. My original order was sent by Speedpost (premium service) and took 10 days to arrive... '

Battery has been charging till about an hour ago so I'm going to keep it of the charger now and see how it goes :)
[Desire Accessories] paprkut:
they sent out mine on the 7th sept, they also sent me a tracking number since i got pretty sick of asking if it had been shipped or not. im hoping it arrives this week since its left hongkong
[Desire Accessories] DrHRH:
Cheers. I've got my number now. Still no battery though. Let me know when yours arrives
[Desire Accessories] whoosh71:
Quick update; the new battery has been running for 48 hours now and is at 21%. This is with a single initial charge and it's below the 25% where the broken one would die so things are looking good.
[Desire Accessories] whoosh71:
Another quick update: my phone just beeped to tell me I have 15% battery remaining :) so all seems to be well!
[Desire Accessories] paprkut:
*jealous* :p. But good news
[Desire Accessories] wanted008:
Update: I received my battery on 13/09/2010.

I gave it just one 12hour first charge. And its been running for 1dy 12hr 34mins so far and has 34% battery left.

Android system 24%

Cell standby 24%

Phone idle 19%

Display 6%

WiFi 5%

Phone calls 2%

Nearest hotel 20%
[Desire Accessories] paprkut:
I thought you got a refund?
[Desire Accessories] wanted008:
Yes I initially did get a refund, then I got and email guaranteeing that it will ship out the same day so I bought it again.
[Desire Accessories] paprkut:
Bah. Still not here!
[Desire Accessories] xlxl:
with a so called "3200 mha"? That still sucks. I need some battery, that will give me at least 3 day battery power!

because blackberry with always push-mail can still stay a week without recharge!!:(
[Desire Accessories] DrHRH:
Mine arrived on Wed but I was away til yesterday. I'm pretty chuffed I must say. They've included a new back cover, a hard case and a belt clip. I charged it for 12 hours overnight and have really caned it today. Left the screen on for about an hour and a half by accident, as I'd been playing a game and didn't realise I'd left it on!

The battery is currently at 14% so looking good in terms of calibration.

Fingers crossed.

I'm really hoping it carries on like this cos I'd love to recommend Mugen to people.

I'll keep you all posted.
[Desire Accessories] wanted008:
Update; second 12 hour charge lasting for 1 day 10hour so far with 22% left.
[Desire Accessories] paprkut:
Still.not received mine yet. Hoping it will arrive on Monday. Weird thing that I can't track the parcel to see what's going on in the uk
[Desire Accessories] DrHRH:
Don't fret, I reckon you'll get it soon. They seem to be sticking to their word, Mugen.

Patience is needed - good things come to those to wait!
[Desire Accessories] wanted008:
Update; after third 12 hour charge 10% battery drained after 1hr 50mins. This is not good as the first charge lasted much more linger than this time.
[Desire Accessories] paprkut:
Used it more maybe?
[Desire Accessories] paprkut:
received mine today too, seems they included the extras in mine too.
[Desire Accessories] wanted008:
The usage was same as the first charge. But I am still happy with it at least I don't have to charge it 2-3 times in 24hours any more.:)
[Desire Accessories] wanted008:
The down side of these types of cases is the locks break easily if the phone falls. I normally used to use a flip leather case I would love to see a version for the xl battery version.
[Desire Accessories] paprkut:
Yeah that's what I thought. Nice of them to include it though
[Desire Accessories] DrHRH:
The belt holder doesn't actually work for me if you have the case on. Has anyone else tried theirs?
[Desire Accessories] paprkut:
Nope.

Any.updates on the battery life?
[Desire Accessories] DrHRH:
Battery life's fine, as far as I can tell. All I need is for it to last until bedtime. Which it does. I usually end up with about 40 percent at the end of the day but I use GPS and talk a lot on it. I'd call myself a heavy user.

I imagine if I could avoid using the GPS I'd probably get 2 days out of it. Problem is I'm always driving to new places every week so I really rely on SatNav
[Desire Accessories] launton:
I've now got one of the mugen extended batts. I think it's a revised one seeing as they were out of stock till the end of September. This is my initial charge (over 15 hours) and overcharge shows the following:

Percentage 38%

Voltage 3757 mV

Status Not Charging

Health Good

Temp 21

Uptime 61 hours 49 mins 47

I can only compare this to the stock batt which would need charging every night. Looking at my percentages I think it's gonna be Monday before I have to charge this again which is brilliant for me and exceeds my expectations.

I'm a 'medium' user. wifi gps etc all on. Updates to apps every 30 mins.

Did not clear batt stats phone stock froyo (although debranded)
[Desire Accessories] wanted008:
I really can't complain regarding this mugen 3200 mAH battery. The longest charge time I've got so far is 2 days 15hours with 20% left with average usage like few calls and WiFi .

I am a really heavy user so after heavy usage it seems to last for 24hours only. Well that's good enough at least I don't have to charge three times a day like I used to with original battery.
[Desire Accessories] paprkut:
Well Ive used the battery for abit and have had a chance to test this out. With wifi sync and 3g / wcdma on I got around 1.7ish days with moderate to high useage. This lncluded texting and browsing the internet.

On flight mode with mobile networks switched off and no wifi I managed 3 2 hour films with around 30% left.

On basic network mode letting me receive only calls and texts with no wifi on either. I managed to get around 8% of battery being used per day before I speed drained the battery. 8% was achieved with nocalls being made and about 2 texts being sent.

So overall there's a definate improvement for both heavy and light users.
[Desire Accessories] cooljonL:
I don't get how my phone can be using 60% in one day or light use!

I'm using LeeDroid, but it was the case on Stock too.

I drop the back light to 40%, bluetooth, wireless, mobile internet and gps off.

I've tried app killers, SetCPU to underclock ect but nothing seems to be improving the battery. Kinda stumped.
[Desire Accessories] DrHRH:
Sounds like the capacity isn't being used. Assuming you're using the 3200 Mugen battery. Install vizBattery widget (or something else similar) and see what the battery health, voltage etc is. When you've fully charged it you should see around 4100 mV.
[Desire Accessories] alex_mib:
Hi, guys!

so is there a reliable extended capacity battery you can recommend?

Thanks.
[Desire Accessories] DrHRH:
Have a read through this thread ;-)

It's all explained! The Mugen 3200 is recommended
[Desire Accessories] alex_mib:
Yep, I'd read that if I had time =) I just found several of them for sale and don't know which is better. I just read somewhere their capacity could be less than it is said on it...

Mugen 3200, does it really hold the charge 2.2 times more than standard battery?

I found also 2600 mAh http://www.hippomodo.com/Desire-Ext...froogle&utm_medium=organic&utm_source=froogle

Naztech 2600 http://www.configuremyphone.com/Naztech-2600mAh-Extended-Battery-with-Door-for-HTC-p/hy10822.htm

ElectraSpan BoxWave 2600 http://www.buy.com/prod/electraspan...re/q/sellerid/19656454/loc/111/217278469.html

Did anyone tried these?

Thanks.
[Desire Accessories] paprkut:
Dude I know its tempting on a cheaper option but seriously get the mugen. You'll wish you got one after you've bought one of the cheaper options
[Desire Accessories] alex_mib:
nah, its absolutely nothing to do with money, I thought 3200 would make the phone bigger than 2600 ones. And, if there would be high-quality 2600 I'd better chose them.

So does Mugen 3200 REALLY holds 2.2 times more charge than original 1400? If yes, then I'll get this one without a doubt.
[Desire Accessories] launton:
It depends on how much you use it. I get 4 days without charging with the mugen. The cheaper ones are the same size. I have one.
[Desire Accessories] alex_mib:
so, is the problem with phone shutting down at around 20% of charge solved now by Mugen? Does the phone warn you as usual at 15% then 10% and so on? Is there a need to reset battery stats or it works now good out of a box?

Thanks in advance!
[Desire Accessories] launton:
I've ran mine down to 8% then plugged it in.
[Desire Accessories] paprkut:
All fixed.defiantly worth it imo. Just for the extra juice if you should ever need it.
[Desire Accessories] alex_mib:
I sure need that! Extra juice didn't harm anybody yet =)

Thanks for replies, guys!
[Desire Accessories] DrHRH:
As Paprkut says, there's no problem with the new Mugen 3200. Worth going for it I'd say.

N.B. Make sure you follow the instructions and do at least 5 full conditioning charge and discharge cycles before you start using the battery as you would normally.

That means: charge it for 12 hours, use it until it gets down to 15 percent, then do another 12 hour charge. Repeat this until you've done it 5 times. That way you should get the maximum charge out of it.

Another tip. Buy an external charger from eBay or wherever for around 10 GBP. If you charge the battery externally you will get a "fuller" charge. The science behind it is: there's some sort of an issue with the phone's capacity measurement and 100 % doesn't necessarily mean that it is completely full. Don't know why but there you go. I definitely seem to get longer from it when I've used the external charger.
[Desire Accessories] DrHRH:
Not so sure about that actually!

[Desire Accessories] alex_mib:
Thats horrible, and see, its Nokia's original phone and battery! What a piece of crap!

I've heard about Mugen long time ago, but never tried it. Just received my new 3200mAh battery from them and I really thought the phone would look much worse, BUT I like the look, I like the weight and grip! The only question I got, does your new back panel kinda "goes over" your phone? See pics attached. Old panel was just making a seam, but new one looks like is over the phone a little bit in the upper side. Its not that big complain, but its pretty expensive stuff and it should be all perfect...

http://bayimg.com/BAAPmAaDa

http://bayimg.com/BAApPaada
[Desire Accessories] DrHRH:
Yeh, that's normal. It doesn't quite fit perfectly but for me that is really not an issue. The fact that I've got piece of mind regarding battery life is the only important factor.

The phone is definitely much more comfortable to hold than with the stock battery. I made a DIY case for my phone from the rubber skin I used before I bought the Mugen battery. I simply cut a piece out of the skin with a Stanley knife to allow the extra depth to stick out. Now the imperfect join can't be seen.

I'll take a photo at some point and show you what I mean.
[Desire Accessories] alex_mib:
That's interesting, let's see how it looks!

Sorry, it's proving trickier than I thought to get pictures up here. I'll sort something out asap

Right, hopefully these will give you an idea of what I mean:

Another Extended Battery problem

Just found this thread after searching a lot for similiar problems.. I've bought the Cameron Sino 2400 mah battery. It does not have the auto shut off at 20%, but does have other peculiar problems.

Twice when I was using it, it came to 22%. I put it in sleep mode, and after 10 mins when I wakened it, it had gained 6% of battery life. This happened two to three times. I guessed that it was calibration issue. Resetted battery stats a couple of times. Twice when it was near 10% and when fully discharged. Another problem is that the battery does not charge fully when switched off. I mean, if I had charged to 100%, switched it off and again charge it while it is off, it never gets fully charged, at least not even after 6-7 hours.

Anyone else have this problem..
[Desire Accessories] DrHRH:
Haven't had that problem but I know that the Desire has calibration issues with charging with the normal cable plugged in to the phone, even with the standard HTC battery. I recommend you charge your battery in an external charger and see if that helps. They're not expensive on Amazon or Ebay.
[Desire Accessories] alex_mib:
It looks not that bad!

Then only problem I got now is that this new battery is well enough for 1 day hard use, but even if 2nd day is light usage it won't be enough. So anyways I have to charge it every day during the night, but thats definitely better than charging during the day!

Also, I noticed if battery is about 40-50% and I put it on charge overnight, the phone shows 100% in the morning and the led light is green, but once I disconnect it from the charger it drops down to 90% immediately. Then I connect it again and it starts to charge again and led light is red, like its charging...

Anyone has smth similar?
[Desire Accessories] paprkut:
Common problem. Most if not all desire owners have the same problem. Best way to sort it is flash the cyanogen mod as that has a hack to fix it.
[Desire Accessories] DrHRH:
Have you got a link to a specific thread on this Paprkut (or anyone else) by any chance?
