Mugen 1800mAh & 3600mAh Battery

Here's two batteries from Mugen Powers, a 1800mAh and 3600 mAh. From my understanding, The 1800mAh will work with the original stock battery cover. And of course the 3600mAh, has the bulkier build. Here's some links for those interested.

3600mAh is sick but im going to order the 1800 mAh i wish they made a 2000mAh normal looking battery with the stock cover.
Thx for the post!

Let us know how it works out. I'm curious if there are any heat issues associated with the larger-capacity battery.

I just bought the 1800mAh, but it will be shipped in 10 days and will take 10 more to arrive!

anybody got a 1800mah one yet? thinking of getting one but im not sure they are worth it, has anyone had a battery from these guys before?

Mugen is one of the best second party manufacturer for batteries! It's really quality, no Hongkong Crap.

Interesting, Ive always wondered about suposedly good aftermarket batteries. ....Mugen you say !

OEM batteries is the only option unless the battery is inbuilt. Why are people so gullible? The manufactures always uses the best cells for their phones as it is part of the features present, i.e. long talk/standby time.
I have a HD2 and bought two original batteries which were not from Ebay.

maybe its because the people who know they are no good are so patronising when they are saying such. Not everyone has knowledge of these things and not everyone has had experience of this before but thats no reason to talk down to them. Its logical that these batteries should be better, after all they are rated 400mah higher, if thats not the case then you cannot blame the person who buys it thinking it is.

After market batteries is not a new phenomena and people buying such batteries should have learned by others which have made those mistakes before. It does not matter if it says Mugen or whatever on the battery.
I bought a battery for SE P1 on Ebay for 3 GBP and the picture was showing the retail package. When I received the package it was a "Walkman" branded when P1 is a business phone. I filled a complaint and received my money back. I would never do it without PayPal covering the full amount. I knew it from the beginning, if it sounds to good to be true it is not.

no, but what about somebody doesnt know anything about battery tech, or somebody who simply bought their phone from and o2 shop and has never had experience of other people buying aftermarket batteries? how are they supposed to know?
i came into this thread asking questions because to me it seems a little too good too be true, i know very little about battery tech but i do know a fair bit about other areas. other people, even those on this site may not have the slightest clue other than 1800 is more than 1400 and to talk down to them because of this is very unfair.

Mugen makes horrible batteries and have a long history of such incidents such as the ones above.

£26+ for 400mAh more - seems a bit steep IMO.
Better to buy a second genuine BST-41 from SE - seen them for the same money all over the place:
For example: http://www.amazon.co.uk/EMARTBUY-GE...6?ie=UTF8&s=electronics&qid=1274285908&sr=1-6
and

So long as it arrives with SE logo and hologram on it, it's probably fine.

Not true. The P1 battery from Ebay did have a hologram but when comparing against the original battery there was a visible difference.

Mugen 3600 mAh battery
I got my 3600mAh battery on Friday and it works great! 5% drain an hour even with heavy useage. I can go the whole day without charging and still have 30% before I go to bed, beats the OG battery which I had to charge 2 times a day which sucked...

I'm personally a bit skeptical to 3rd party batteries, but I would like to have a 3600mha battery, the added thickness is not a problem. But as far as I know there only available battery from Sony is the stock 1500mha battery?

That's exactly how my original battery behaves... lol

Not for me.
My original 1500mAh battery was dead by 3.30-4pm after taking it off charge at 8.30am and that was with moderate use. Its been dead by 2pm before now.
Got my 1800mAh Mugen battery and i can take it off charge at 8.30am and have it still on 40% at 5pm after heavy use during my lunch hour.
It does work much better

Saw an eBay auction for the Mugen battery set up by "Mugen Battery".
Read the lower lines and they want to add 19% VAT after the sale is completed to all EU buyers by sending you a separate bill for the VAT (totally against eBay rules)!
What a bunch of shysters!

Innocell 1600mAh Slim Extended Life Battery

Available here! Who wants to try one first?

Me definitely! $50 seems like an awful lot to spend for an extra 200mAh though

I would but no money right now. Hey anything would be better off then the OEM 1300mAh =)

stock is 1400mha.

something tells me the stock battery have a higher capacity than those crooks using inferior cells while inflating the numbers.

You are most definitely right I bought one if those for my G1 and it crapped out within a year. Your best bet is to take your chances with the cheap batteries on ebay. You can get ten of them for what one from Seidio charges you. No knock on Seidio.

dunno where i saw it (somewhere here on xda prolly N1 forum) but some guys put every aftermarket battery for MANY phones up against HTC's stock batteries the astounding results:
NO aftermarket battery from ANY mfg. has EVER beaten HTC's stock battery...
(this is referring to batteries that fit in stock battery enclosure)

I agree after market battery might show higher numbers but not as good as the stocks ones

me 3 right under a year mine crapped out and it never seemed much better than my 2 year old htc it replaced.

I'm surprised, I've had good results with extended batteries. The one I got for my G1 did considerably better than stock. (8-9 hours versus 6 with OEM battery.)

I bought 2 1500mAh batteries with charger from ebay for less then $15 shipped. They last less then stock battery does (I kill stock battery in about 14 hours, the ones from ebay last me about 10-12 hours) but I always have charged spare battery now. Great investment IMHO, no way I would pay $50 for 1 battery, not even original HTC.

Hey Zoltair, What brand was the one you got that was better than stock???

Well I should hope that an extended battery would give you longer life then a stock...seeing as how its suppose to. I don't think that the problem is whether or not extended batteris last longer, because I would think if you bought an extended battery and it didint last longer then a smaller, stock battery..you would then return it...I think what people have problems with is getting what they pay for, price per mA and how much mA there really is...if your paying 50 dollars for a battery rated at 1400ma, your probably going to want all the mA you payed for...for example: (PURELY FOR SPECULATION, NOT REAL NNUMBERS) say you have a stock 500ma battery and you get like 4 hours out of it or whatever, and then you purchase an extended battery for 50bucks and its "rated" at 1000ma, yet you only get 6-7 hours out of it...? Then it would seem that it isn't truly rated at which they say it is... Then you get into how much certain companies value their own integrity, and how much they are going to inflate their own battery ratings to simply sell the product. Examples of this can be found on batteryboss.org ...This website obtains batteries and tests them, and you can see clearly, some companies inflate their ratings more than others... If you look at what the battery was rated at, and what exactly it tested at...they even break down price per mA...so if you paid 2dollars per mA for a 1500 rated battery and it tested at 1300..how much money are you losing? Purchasing an extended battery should be looked at like all consumer purchases, weight the pros and cons... and read reviews on companies, you can also seek alternatives such as previous post in this thread of having spare OEM batteries that cost 1/10th of an extended battery, yet they immediately doulbe your battery length..

No word yet on performance on this? Anybody get it? I don't want to go first, lol!

Well $49.99 for 1600mAh is high as hell and top of that from unknown source, might well as wait for Mugen power stock size. I hope whoever has this post data on it so we can see if its any good.

Got one of these for my N1. Definitely NOT worth the money. Don't notice any difference from the OEM.

Do yourself a favor guys....

Stop the debacle and concern on whether or not the 1700mah, 1600mah 1500mah blah blah blah batteries are better than stock.. I have a LOT of experience with Li-Po and Li-Ion batteries (cell phones use Li-Ion technology) and I can tell you WITHOUT a doubt that all these knock off companies are full of SH^* trying to say there batteries are of a higher capacity than the stock battery while staying the same size. Although it is possible to cram more mah into the same size package with li-ion batteries it is VERY unlikely to be able to do so with the current technology out right now. Most of these companies rate their mah on a different scale and actually will pull the battery to a lower voltage to justify their claims when it dosent matter because cell phones have a safety feature that has to shut the phone down at the specified voltage to prevent fires. Yes fires, Li-Ion has a fire risk if it is depleted all the way, not the same risk as a Li-Po battery but a risk just the same. HTC has a separate department that deals specifically with batteries and I can assure you they know and use the most up-to-date batteries they can get their hands on for these devices. There is nothing for them to gain by using inferior batteries in our phone. Those that have purchased the seidio 1600 extended battery and claim to have a better life on the phone are under a placebo effect. If you are just purchasing this "Extended" battery as a spare than buy all means go right ahead but dont expect a miraculous two hours extra from it because it is of lesser quality than the stock battery. I have hundreds of dollars in battery testing and logging equipment and If you guys dont believe me i will run some tests on the stock vs. whichever battery you'd like me too and post the data for all to see, but Ive been down this road before with htc phones and have always come up with the same conclusion......The aftermarket "Extended" batteries actually have less mah's than their stock counterparts.
Of course Im not referring to the htc extended battery in this post, its obviously pushing more mah's with its monstrous size, lol.
....just sayin..

Oh' and to elaborate because Ive also read some concerns over the length of time for charging the thunderbolt (which does seem lengthy I will admit).
Since our phone has such a hard time time keeping up with a normal days use I believe what htc has done is given the battery a longer "saturation charge" for the battery to completely charge before it completes the charge cycle.
Li-ion batteries are charged on a 3 cycle charge system and stage two is what is considered the saturation cycle where the battery may sit at a relatively static voltage for a period of time to saturate the cells with current to top off the charge, some cell phones skimp on this step to give the phone a fast charge time which is termed "charge-and-run" and people assume the device has been adequately charged when it has not. For an adequate "FULL" charge without harming the battery or affecting battery life, typically li-ion batteries take approx. 3-4 hours.

So the 3 batteries I got for 12$ on ebay ARE paperweights?

Sent from my ADR6400L using XDA App

I wouldnt go that far, I doubt any of the batteries are "paperweights" yet. Im just making the point that the claims of higher capacity are unfounded and the cheap knock-offs are of lesser quality. Also check where the batteries are made. Good quality Li-ion cells come from Japan.
One thing to note with the cheapies is the temp while charging or under heavy use. Get a temp monitor app and compare between the stock and your aftermarket batteries, they will probably run hotter. Unfortunately I dont have any other batteries to test for you guys other than the stock OEM battery otherwise I would. If I pick any up Ill cycle the stock vs. aftermarket and post the data log between the two.
Also I didnt mean the "fire" comment to worry anyone, Li-ion batteries have protection curcuit that will render the battery useless and unserviceable if the cell reaches a voltage of 2.70v or lower which is where the chemistry of li-ion becomes unstable.

I'll ship your one of the two 1700 when I get it if you wanna test it and post results. Just ask that you ship it back after your done.

ha, I bought the same ones you did.
I didn't expect them to be as good as the 1400 mAh battery that comes with the phone. I just wanted to have a spare battery available in case I'm traveling and watching movies or something (on a plane). Even though it says it's 1500 mAh, I expect them to be more around 1200 - 1400 mAh.

I used their results when I purchased the Seido 3500 for my Evo.

I've used Chinese batteries every chance I get. They do work. From an Eris to the Dinc. 3500mah. Never had a problem. Emails and games etc. I bought the extended battery along with the Tbolt. Just don't like the hump on the back. I'm on eBay every night waiting for the Chinese to strike with a extended battery. At least a Better extended back cover. For $10.99 free shipping ill wait 2 weeks for it. F%$% what u heard their cheap batteries work.

If you do I recommend you buy the 1500 MyTouch4G batteries from ChiChi's htcexpress or their store on amazon. They should be the same a the 1700 Thunderbolt batteries and $20 cheaper.

When I get around to ordering up the batteries Ill post a chart like that on a seperate thread for our phone. I have some pretty sophisticated logging equipment. It shows the temp, charge capacity, voltage, mah, cell balance and health in an easy to read graph.
Im not a battery nerd but I used to be into RC helicopters BIG time and when you have a $5000.00 helicopter that can kill someone its just normal practice to have the equipment to check your $800 batteries so they dont fail 80 feet in the air and blow up or decapitate someone, lol

Heres a video of one of my helicopters (Trex 700 electric) , this one uses two 6s 5000mah li-po batteries and each one costs over $300 and they only last 8 minutes before there dead The video isnt of me however, I need a video camera to post mine but the helicopter is identical for the most part.

(speaking from g1, nexus, and g2 experience only)
i've bought extended batteries for phones for less than $15 each all in the 2400 to 3600 mah range. they last 2-3 days with normal use. the oldest one is 3 years old (g1) and still performs like new.
iirc the seller was based in hongkong.
just saying.

the htc extended battery
personally of all the batteries i have tried this is by far the best one until sedio has an 3500mah then i will be getting that i think

Mugen Extended Batteries! Woopie!

Hey everyone! I asked Mugen if they're going to make any extended batteries for the SGS2! Guess what?:
Look at my attachment They said yes!
I've been a big supporter of Mugen, they've made some WONDERFUL batteries for my older devices (blackberries mostly), and I certainly hope to get an OEM sized (20% more powerful) mugen battery in my device.
Will you guys?

Samsung makes that, as well: http://samsunggalaxysforums.com/sho...ective-case-extended-battery-power-pack-combo
Which I might get as well. It all depends. I'm waiting this week to get mine SGS2, most people say it's OK. While others moan about its horrible battery life. So I'm not sure. I'll test it out and see. Regardless, I will get the mugen one that fits OEM. And if it's too little as well, maybe the case. All I know, is that I'm already in love with the SGS2

If they would be able to make 2500mAh batteries with the same thickness as the original, I would be happy

Well, they can't do that, maybe 1850, 1900 mAh tops.
What I was thinking off was a battery which is a cover at the same time. A bit like the batteries on the nokia 6210 and 6310i of long ago. You could get those from Nokia in the 'small', normal, and 'large' variants.
The SGS2 and battery construction allows for this. I.E. a battery that 'snaps' on and is the same height as the thicker part of the telephone on the bottom. Such a battery if constructed properly should easily be able to hold +/- 4000mAh while adding little to the overal phone thickness.

anything over 30% more power as the same original size i think its worth change anything under that change my vote to from YES to NOOOOOOO WAY.

Easily 4,000? I don't think so. You're talking about the actual battery + a few more mm for the top. Now, the rest of the body will be the same thickness of the same cover, right? Then that'll make it impossible to construct any usable MAH into that! So we'll get around 2,000 mah. Which by my standards is just frikken fantastic! I'd buy that in a second

I would highly recommend all of you to take a look at this page:

The findings are pretty clear; 3rd party batteries _never_ hold up to their supposed mAh-rating.
If there was a way to make a battery of the same size larger capacity why wouldn't Samsung have done it? Battery capacity is a _huge_ selling point for mobiles, Samsung has truckloads of money and huge departements doing R&D. The same can also be said for all the other big manufacturers.
But lo and behold, time and time again some rather small battery making companies release 3rd party batteries that offers upto 30% increase in capacity at the same size as the OEM batteries, it's just amazing!
One thing is oversized batteries giving you some more juice for your phone (not exactly what it says on the box there either...), but never take a 3rd party's word for it if they say they can cram more capacity into a same-size battery than the original. More often than not they have lower capacity than the OEM batteries despite being rated much higher.

Those are awesome news!
I hope they release it soon!
My experience with the 3200mAh extended battery for SGS was excellent!
I wish they released a smaller one of about 2500mAh of capacity for SGS II, that would be astonishing!
Either way I am looking forward!

You obviously never bought or used a geninue Mugen brand battery before then. They're probably the only company that doesn't make ridiculous claims about battery life.
And just because the manufacturer doesn't squeeze more power into their batteries doesn't necessarily mean it can't be done. They do have cost considerations and a profit margin to think about after all.
EDIT: I expect Mugen's OEM size battery to probably be around 1750-1800mah, or about 10% more capacity than the Samsung one.

Just to clarify, it's not always OEM size. It could be a tiny bit larger, but still fits in the OEM slot. That has been the case with all my blackberry batteries. Why my trusty OEM batteries fit comfortably, the mugens still fit well, but are a little bit tighter. So that DOES justify an increase in mAh.
I have also tried non-mugen / seidio and OEM batteries, and those are ALWAYS crap! Capacity usually drops after 2 weeks or even less sometimes. They're horrible. But mugen has always made great batteries (at least in my case) and I would highly recommend them to anyone Seidio ... meh... Not so much! Because they're REALLY over priced haha.

What tests have you done that proves Mugen's claims are true? Oh really, you didn't do any except anecdotal ones about your own use?
If people want to spend money on batteries with supposed higher capacity, good for them. But us rational people at least won't have to

I had a bad experience with a mugen battery. Bought it, charged it, used it for one time and it crapped out on the second charge. Dead.
Called and emailed for support and they wanted me to send it back, plus tracking, I wasn't going to pay more.
Basically I threw it out. My loss. But I would never by a battery from them again. It looks like cheap stuff of ebay anyways.
Maybe you'll have better luck though.

You quoted one sentence and didn't bother to look at the link I posted?
Let me paste it here then (first mAh rating is what they claim, 2nd is actual mAh rating):

True, I was feeling a bit lazy yesterday
Interesting link. Yes, my last Mugen experience was anecdotal (Xperia X1), but if my extended battery had really only lasted ~70% of claimed capacity I would've noticed (plus there would be more people complaining in the forums).
Guess they need to tighten their QC then.

was looking forward to a plausible 1800mAh standard size battery from mugen... 1700mAh is barely any jump and in all seriousness would have the same or even lesser battery life than the original one.

Wow, 1700 from 1650? That's nothing. That's literally minutes (10 maybe?) of the screen being on! I would totally skip on that one.
Samsung also makes its own extended battery case, which might also interest me... We'll see

[Q] Toke my HOX apart, need internal HI-CAPACITY battery

Hello All,
I toke my HTC One X apart to replace the internal battery with a higher capacity one, as i've tried all the methods listed here to enhance my battery life, but it failed to survive a 12 hours idling - it seems that HTC forgot that the user might use his phone through the day -
anyway, i'm looking for an "INTERNAL" and "HIGHER-CAPACITY" like 2100mAh, 2400mAh battery to replace my 1800 mAh one, any suggestions please?

I don't believe that there is a higher capacity internal battery for the HOX. From what I've read on here is that any higher capacity battery would require the a bigger case for it. Just by opening it up you have now voided your warranty, and any third party manufacturer would not make you void your warranty to increase battery capacity. Your only option is to buy the cases that utilize the pogo pins to increase your battery

thanks for your reply teky, actually i dont care about the warranty, but i believe i can find a higher capacity battery as the iPhone one, i've bought a 2300 mAh from ebay for my old iphone and it was at the same size as its original one, the performance was amazing, it lasted about 2 days with a heavy usage.

likeliness is, if it wasn't physically bigger, then the mah was no more than the original. probably the fact that the first battery was knackered and just buying a new one seemed like it was lasting longer, when in fact it wasn't lasting any longer than a new original battery..

btw, the battery in the 1x is soft...gg, how were u planning on replacing it.

i need too an hi-capacity battery, but...is simply to remove the internal battery?

Be careful... A design flaw in the custom battery may cause it to explode.

Every battery I've read about online that promised higher capacity for the same size proved to be a fraud. The best story I saw was posted on the xda-dev forums. The user cut off the outer packaging of the battery to reveal the original battery inside, and printed on this was the real (much lower) capacity.
I don't know much about battery tech :silly:, as I'm about to prove but ... I believe it's basically a chemical reaction that releases power (and the reaction is revered when charging). The capacity of the battery is related to the volume of material available for the reaction, so basically physics is against us on this one.
If it seems too good to be true, it is. If technology were available to produce safe, cheap batteries, of the same size with a higher capacity, why doesn't a single large reputable manufacturer produce what would obviously be a lucrative accessory?

Are we not missing the point that his phone can't do 12 hours idling? My wife's currently very under used one x has managed 7 days and 10 hours from a single charge with 3g on almost zero screen on so true idle.
My used one x can easily make 2days of what I class as moderate use.
There must be some software issue or as Vodafone in Perth did a misconfigured network stopping 3g from going idle and sucking the battery dry.
Cheers
Steve

you can use the battery of the hox+ and get an extra 300mAh ...
but am going to take the batt of my spare one x and see if the battery of the htc butterfly s would fit... you get like an extra 1200mAh
hope it does....

Please make a thread about that, even if it doesn't fit. Battery life on my HOX is crippling, hardly get 2 hours screen time.
