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?

The battery is still under deveploment, but i suspect soon will be available.
for those of you who are fimilar with extended batteries, which is better, Mugen Power or Seidio?
I used to run a 2600mah battery in my G1 from them. I loved it. Im waiting for clearer pics of the Mugen battery door though, this one isnt that great looking but the price is much better.

Will this battery still allow the full use of the NFC reader?
On the website they say that it "Adds only .8cm to your device"
It's almoast as thick as the phone itself???
Am I right?

Great info!
Great to know! I also found this blog site where other companies like Mugen Power offers Nexus S extended battery with battery backdoor. http://www.mythoslife.com/2011/04/nexus-s-now-has-extended-battery.html
Like title says.. I've been trying to find a extended battery which has higher capacity yet the size of the original battery but no luck
Does anyone know if there is one and where to fine one
Thanks

are you sure that's even possible ? unless the battery was made of some other kind of materials, I have tyrouble seeing how you could store more power in the same battery size.
If you don't want a bigger phone, Your best bet would probably be to buy a second standard battery but it's a hassle to swap the battery when it's empty
If the battery is the same size it could in theory have more juice but it would be negligible. Seriously though, I picked up a charging cradle with battery charging slot and 2 spare batteries for $20. I also have a car charger and 3 chargers in my house. Unless you get a battery that is about double the size, you won't see a big difference and even then many batteries don't live up to their specs. Chargers and spare batteries are cheap. We're not dealing with smartphones of a decade ago where everything was proprietary and would cost at least $30 a pop.

I remember reading something about this... I think it might have even been on this forum but it was something along the lines of "Don't you think, if it were possible to fit more juice into the same size battery, that samsung wouldn't do that with their OEM batteries?"
Samsung, and I'm sure many other major device manufacturers don't just buy a battery off ebay and throw it in their phones. they spend time and money researching better battery technologies to get the best power/life they can.
It's my second day with an Andida 1850mAh battery, no big changes yet compared to my 8 month old 1500mAh OEM battery, i'll post back after a few complete drain and charge cycles.

Be careful buying those batteries. More often than not they just repackage 1500 batteries and Mark up the price :/

After 3 complete charge cycle its a little bit better than OEM but no big improvement. I'll see in a few more days.
I finally get about 15% better battery life. For the 20$ it cost me, I'm happy.

How long have you had the battery? I'm looking for a new one as well but not if I am going to get scammed. Thanks!
Not Nexus related, but I have a vibrant that I got the Galaxy S 2 Epic 4G Touch battery for recently. Battery life went from about 6 hours to dead (month old 1500 mAh replacement battery bought at a phone hut) to 34 hours to dead (new samsung 1800mAh battery.) Nothing else changed.
My point is this:
1. If the above statements about samsung packing in as much as possible are true, why didn't the vibrant have a 1800mAh battery from the start? (hint, it is always about money.)
2. Take a crap 1500 mAh battery, slap a 1800 mAh sticker on it. People that buy these batteries will see an improvement because most generally they are replacing a worn out battery with a new one. Of course you will see an improvement, your worn out stock battery has only (arbitrary number) 600 mAh worth of usefulness left. The replacement is new and is not worn yet. (All arbitrary numbers follow) So, you will still see an improvement if you take a rated 1500mAh battery, that is labeled 1800mAh, but is in actuality only 1000mAh.
So asking if there is another, bigger, better battery for the Nexus made by Samsung, is a very valid question. So:

Because it is a device from 2 years ago (2010) and the S2 is from q3 2011. Maybe two years allowed them to cram more juice into the battery.
Maybe it wasn't viable then, to stick such a large battery, considering the power consumption of the vibrant compared to the S2. Maybe if they did the price would have gone up.
I highly doubt that Samsung would just stick different stickers on the same capacity batteries. maybe you had a defective or a non-original one. There are people that measure this kind of stuff. How much damage would Samsung's image suffer if someone found out that they sell a 1000 mAh battery with different labels and price tags?
I got a gold 2430 mah battery from ebay. http://www.ebay.com/itm/2430MAH-HIG...093799?pt=PDA_Accessories&hash=item2c5edcdce7
i don't know about it holding 2430mah, but it's far better than my 1 year old stock battery. i can post some battery usage stats later.

"Take a crap 1500 mAh battery" In this case "crap"="non oem"
I figured that would be obvious with my prior "phone hut" comment. I guess not.
----------------
I am a big fan of the OEM batteries. I have not tested a non-oem battery that will perform anywhere close to the stated specifications so far.
If you guys find some good battery reviews, tests, etc. please post up.
Keep in mind that comparing a brand new "Craptastic Brand™" battery to your old worn out OEM battery is kind of pointless for getting a feel of the comparative quality/capacity of a battery.

Sounds great!
Does anyone know of any extended or aftermarket batteries that could work with the Droid 4 by replacing the internal battery?
I understand it is an internal battery, but that does not mean it cannot be removed :good:
You can take it out, but it's not supposed to be removed, so as far as i know no one makes one for the droid 4. Some ppl tried putting in a razr maxx battery, but they then found out that the battery doesn't fit into the same slot. What you can do is get an external battery or maybe you can see if they make cases with battery's in them like they do for the iphone and other devices. Hope i helped.
I have been looking for a case that has an extra battery in it and i cant seem to find one anywhere. If anyone finds one please let me know. I use my phone everything so it would be nice to not have to take my charger with me all the time.

Do Droid 4s share the same battery with a Razr? If so, the Razrs can upgrade to the Razr Maxx battery with some tinkering. I foresee problems finding a bulged backplate for a Droid 4, though.

did you read the 2nd post in this thread?
the mugen site doesn't list the d4. closest thing is the d3 and photon (not the photon q, which looks a lot like a d4), both of which have regular removable batteries, so it doesn't look good for us. esp now that it looks like the droid5 just got leaked... and it doesn't seem to have an easily replaceable battery either.

I just puchased the mugen extended battery. It does add a little more bulk and unable to get a case that will fit the larger door. Other than the power meter not able to show true battery life. It is a software limitation. I do like the longevity of the battery though. My original battery would die while I was asleep after about 5 to 6 hours offBT the charger just sitting idle with no wi-fi or BT on.

hey there! Figured I would chime in on some info concerning extended batts for the D4.. Even though I am not sure that this pertains to the particular model you are looking at, I have found one that works extremely well, and does not need an extended back for the phone. It has thicker cells, and I've gotten more than a day out of it. Given that is not full use of course, but still thats almost unheard of (at least for me) when it comes to the D4. Also, I have to say that I was a bit pretentious at first, because this battery is sourced from china/japan on eBay. Anyways here is your link!

Yeh they have a extended battery 2085 mAh using stock door but the Mugen is 3800mAh which seems super capacity tho the device will become a bit thicker due to expanded door.
I don't mind the expanded door just want to know experience of people who have used it - how long it takes to charge from 0 to 100% and does it almost give double battery life to Droid4 when compared to stock battery...
PLSE PLSE share your experience before I spend $100/- :laugh:
I bought 3weeks ago a new battery from eBay. It 2100mAh and the battery life is quite better than before. I was charging after 4-5 hours of use and now it around 6-7 hours of use. What kills it for me when it is 1xmode for internet.....because I have flashed over to another carrier. Im quite happy with the battery.

With my settings running I am getting up to 30h of heavy use...
I don´t think that paying 45 USD is worth the additional 100mAh more but I might be wrong

So this might be a good thing, I just hope that it will not be bigger in thickness, maybe they can figure out how to make it the same size, but i highly doubt it unfortunately

I suppose it will be thicker than the stock. Anker did not offer any improvement in mAh, Mugen offers only +100mAh so I doubt that you can fit additional 1900mAh w/o making the battery thicker. 1-2 mm thicker battery won´t be much of a problem because you still could fit that battery under the plastic cover (tried it out). we´ll see I think, but I am not getting anything that makes my SGN2 any thicker as it is.
EDIT: there is a 4200mAh battery (I suppose total crap, just look at the price) available: http://www.eforchina.com/view/12921...attery-for-Samsung-Galaxy-Note-II---N7100.htm
With this I suppose a 5000mAh battery from Mugen should be possible w/o making it thicker than 1-2mm (lets hope "fingers crossed")
I'm patiently waiting for the Mugen "super" battery. LOL!
I've always had great results in the past, however I've always sacrificed the thinness of every phone I've owned. I guess that's the toss up.

I think that Samsung is improving their own batteries so there is less room for improvement with aftermarket. The Anker battery in my S2 was better than stock, but that wasn't the case with their S3 batteries. Either way, having a spare battery available is really really cool when your away from a charger

Is it worth the investment?
what about the mugen battery?
When you can get an Anker for $8.99, it's beyond me why some one would pay for an overpriced Mugen.
great price.. but i've never had Anker before.. how long do they last? Those cheap chinese batteries that I've had in the past (for my HD2 for example) lasts about 4-5 months and would refuse to charge after that. How is Anker?

I recently bought one of the eCell Gold 4500mah extended batteries from Amazon. When I looked this morning they were no longer in stock. It is an extended battery that uses the stock battery door. Just barely. It is a very tight fit. But I had my doubts as to it really being 4500mah. I just finished my 3rd charge cycle on it and I must say that I am impressed with the results so far. The majority of the screen on time was using FBReader to read a book. I also did some gaming, interenet browsing, texting, and made a few phone calls. I don't know how long it will hold up. I will report that after a month of use.

Is the battery physically larger than the stock one? If it isn't I doubt it's 4500mah...as many "gold" batteries claim much more life but use the same size.
Could you post pictures of this battery side by side with the stock one?
Do you have a link to where we can get one?

I will report that after a month of use.

I don't think you should trust that "Battery Management" app to actually give you the capacity for the battery you use. In that app, you actually type in 4500 mAh for what you think the capacity is and then the app just estimates drainage around that number. It's not reliable to measure the mAh for a battery this way.
From looking at your Android battery usage breakdown, it doesn't look any different than what a stock battery would do. Your on screen time looks particularly low for a 4500 mAh battery should provide and looks in line with the battery stats in the battery stats thread where people use stock 3100 mAh batteries.
Don't know about NFC as I don't use it. Physically it is slightly larger than the stock battery. I don't know where you could get them now. I got mine from amazon. As far as the capacity, I doubt it is much better than stock but for me it is getting about the same or a little better on screen time as my stock battery did. Maybe the stock battery I got wasn't that good but I couldn't get 8 hours of screen on time from it. The eCell was only $20 so that is not a bad price. For a gold battery the performance is pretty decent.
