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?

Had one of their batteries on my previous phone.
3400mAh... though it was quite bulky. What id really like if they would develop a battery which is wider above the battery compartment.

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.

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):
TP2 Mugen 1800mAh 1414mAh 79%
TP2 Mugen, exchanged 1800mAh 1256mAh 70%
Hero, Mugen, oversized 3200mAh 2396mAh 75%
And to add some OEM batteries:
TP2 OEM standard issue 1500mAh 1414mAh 94%
Nexus One, OEM 1400mAh 1357mAh 97%
TP2 OEM, new 2150mAh 2150mAh 100%
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.

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.

Dear Thomas,
Thank you for your email!
Yes, we will have XL and SL size for this battery very soon.
It will be around 1700mAh for SL and about 3000+ mah for XL.
We will announce this on our social networks and on our site!

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.

Anker 1900mAh battery?

Hey guys browseing Amazon or GS2 accessories and I came across the Anker 1900mAh battery.
Now ive had the Anker 1900 on the Sensation and its legit a beast of a battery with extra juice, anyone used this for the GS2?

why not just wait a few weeks and buy the proper 2000mah battery??
iam sure samsung would have made a battery this size if possible rather then build extra back covers due to the 2000mah battery they have designed
basically i dont think anker could squeeze another 300mah into the battery at no extra size , its probably not what it says it is and i would go the official route , i have found all these cheap batterys to be useless in my times of owning mobile phones
to sum it up just buy the offical 2000mah battery from samsung or the bigger one from mugen if you want better battery life

look for anker 2300maH on ebay for $12-14 . buy it and make a review

tempted!
im very tempted. amazon uk has an offer for 2 and dockcharger and travel charger for £13. Even if its 80% of original battery i would be happy. But seems like a new release..not 1 review...
I would get the official samsung one but i have the perfect a leather, carbon fibre cases. would it fit in there? i don;t know...will i find an equivalent case that fits it...i don't no. If only if they had a demo version with new battery in a highstreet store i could try putting my case on,

ohh this make has had some reviews from same phone and different phones
im not advertising lol, just discussing reviews

probably not even half that capacity..

I try the anker battery and doesnt work for me. That battery is bad quality because I charged and when the phone was in 5% the screen staring flashing. The phone reboot when is in 5%. I return the battery and they gave me a refund.

Eug measured the capacity one of the spider foot batteries as 2413 mAh.
Even though it is well under the stated rating there is nothing that touches it for value. USD $10 for a 2413 mAh battery is a fantastic deal.

Go on expansys if you are in the UK...they have them for sale on their website

I ordered an anker battery set. should be here in one or two days will report back

I ordered it, nothing to complain but follow my feeling its not like 1900mha... same as 1650mha... one more thing universal usb travel charge need 8h to full charge( output 350mha+-50mha)
>>> with me, im using USB cable + universal usb travel and ..... im smell something from cable so i never do it again

yes, i do but its my opinion

My experience will be subjective, but I've been using 1900mah Anker batteries for the last 2 weeks. They are OK. With original battery I get 12-13 hours when everything ON! With Anker approximately 16-17 hours.

is 3500 mah battery better than 1900 mah ? increasing number of mah is better or decreasing ?

More mAh is better. Just be aware that the 3500 mAh spider foot battery is actually about 2400 mAh. At $10 that's not really a problem though...

Mugen Power 1800mAh battery (3200mAh also available)

Using 1800mAh battery on his Evo 4G and he love it. Had issues with the price at first but quality proved itself over buying cheap batteries from ebay or amazon. In the end it's cheaper to stick with a good battery.
Check them out, I'm on 3 days usage with 3200mah now.
Check review from Droid Dog here: http://www.droiddog.com/android-blog/2010/10/mugen-powers-extended-batteries-for-the-htc-evo-4g/
3200mAh with battery door
1800mAh OEM socket battery

I'm using the 3200mAh battery from Mugen right now. With a new ICS ROM I'm getting about 18 hrs, sadly that is without 4G.

The Mugen batteries are showing horrible results on battery boss, the 1800mah is less actual mah than the stock OEM that comes with it.

If you'd make some research you'd find out that batteryboss was a project to throw dirt at all third-party batteries out there. The tests were biased and not proven. I'd suggest you trying the stuff yourself and make up your own mind. When the battery allows me to work on my phone for another 1.5 days, I don't care about some stinky site out there.

hmm has 4.35v vs 3.8 oem and has plenty of positive reviews, tempted to buy it

4.35V just the max charge, same with OEM battery. 3.8V is the nominal charge...just another fake battery

they don't. wtfmateim65 implied in his post that 3.8V and 4.35V made a difference, i was trying to clear up that misconception.
since the battery is the same size as OEM, there's no way that this battery is 3250mAh as claimed. also, if you look at the back of the battery it says 4.2V...just another fake like i said.
this seller is also implying in his auction that these batteries have short life, and to ignore it because of a "memory effect" that li-ion chemistry batteries do not have.
all in all, would not trust the rating, but it may certainly be a good replacement for the stock battery -- sans NFC and the extra mAh claimed.

Damn wouldn't that be a nice deal

I´ve checked the negative feedback for the last months of that ebay-shop and other which offer stock size monster battery´s, and some sounds like this: "misrepresented strength of battery", "Bad battery no difference between the original one and this battery very poor", so it seems like clear fake mAh strength. :crying:
I think Samsung itself would equip their flagship with a thin stock-sized 3000 mAh battery if it would be technically possible, but i think it is not and all the ebay items are fake. There are a few other battery’s on ebay with similar strength (2850, 2950 mah), and there are also negative feedback about their real battery performance, except the good feedback for fast shipping or something unimportant.
I bought two weeks ago a Polarcell 2400 mAh battery and I´m not disappointed, but also not really happy, there is almost no noticeable difference in life perfomance between the stock 2100mAh and polarcell 2400mAh (+15%), but i think their 2400mAh is real, because the Polarcell is noticeable heavier and like in all corners 1mm bigger than the Samsung stock.

Nexus 5 3800 mAh batteries legit?

Are those Nexus 5 batteries at AliExpress with a capacity of 3800mAh legit? They even claim it's the same size as the original batteries.

No, this is fake... Maybe the real capacity will have a 1500mAh... Search original or replacement of good quality, for example. PolarCell: http://www.polarcell.de/english.html

I second that (what bykumza writes), if the manufacturer (LG) could have fitted a real 3800 mAh battery they would have done that. Often the more modest capacity values are more accurate. I can confirm that PolarCell are very good, well worth the money. The Chinese cheapies often dissapoint.

Actually Nexus 5 and G2 are released almost same date. Nexus 5 has 2300 mah battery and G2 has 3000 mah. I bought G2 battery and put it in my Nexus 5. It fits but it needs ~1 mm space which is not a problem for LG to do it! But they did not! That company did not put 3000 mah battery in nexus 5 which could have been the bestseller because of price/performance and put 2300 mah in it so they could sell their ****ing G2s with great battery life. So no they would not have done it even if they could. Today companies do not do so much things that they can, we just can't even imagine. Intel, Nvidia, Qualcomm, Samsung , apple and other mobile companies are good example. Why on earth can't mobile companies like apple put bigger batteries in it's super high price phones? Juts why? Samsung managed to put 3600 mah battery in 5.5 inch phone which is smaller then iphone 6s plus or 7 plus which has ~2900 mah and takes 3 and a half ****ing hours to charge it!!!!

Thanks

Fitting G2 battery requires some hardware modification, which I frankly don't feel like doing.
I just wonder which battery is better, a PolarCell one (someone recommend in previous post) or OEM one.

Polarcell is reportedly one of the best alternatives and has a slightly higher capacity than the original cost can say that comes out more or less the same as the original.
Here, unfortunately, you have to answer on your own if you want to take a chance and buy a replacement if you prefer a standard solution.
