Mugen, I think I speak for everyone when I say "please stop." I mean, really? Look at their latest creation, a 5400mAh extended battery for the already gargantuan Galaxy Note:

hli-i717xl_3 hli-i717xl_4

If you own a Galaxy Note and have grown tired of carrying around a small diesel generator, though, this may be the solution to all of your problems. Of course, no one said this solution didn't come with problems of its own. Like looking as though you have some sort of awful malignant growth attached to your thigh should you dare to put your Note in your pocket with this monster attached. I'm not sure Levis are rated for this sort of application.

But hey, if you've got a Galaxy Note, you may not be one to care about size.

This catastrophic collision of batteries and sheer ugly is about $100, and you can buy it on Mugen's website right now.

    How long does this thing last? LOL

    • https://twitter.com/#!/psycho_maniac_ Jerry Lange

      like 5 extra minutes lol jk i dont really know

    • http://www.theandroidsite.com benmarvin

      About 3 days according to some reviews.

  • Matt Schepp

    Headline problems anyone?

    • http://www.androidpolice.com/ David Ruddock

      Too. Many. Names.

  • http://twitter.com/set_iroN SetiroN

    Not any uglier than any other smartphone with an extended battery.
    It's all in proportion - although, considering the larger footprint, they should probably consider producing a just slightly thicker-than-stock 3500mAh battery.

    • fixxmyhead

      the ugliest one is gotta be the thunderbolt extended one. have u seen that thing it looks freaking stupid with a bigass hump on the back and it doesnt even look good or proportionate

      • Tyler Chappell

        but it feels good in the hand

        • fixxmyhead

          That's what she said

          • Nate

             Jokes aside, I'm with Tyler on this one.  I actually prefer the feel of the Thunderbolt with the extended battery.  I'm not a fan of super-thin phones anyway.  To each their own...

    • p3ngwin

       the Galaxy Note's stock battery is 2,500mah.

      this aftermarket battery is therefore over twice the capacity.

    Just tell people its a tumor LOL

    • zurcaled11

      Its naht a toomahr!!!! arglggl

    it's a computer in your pocket 1000000 times more powerful than the computer that put humans on the moon. it doesn't need to be pretty.

  • TheFirstUniverseKing

    That sized battery will likely last the average person far more than 24 hours, as it's nearly twice the capacity of the Droid Maxx's 3300mah battery. Not many people are away from an outlet for that long, so I wonder how popular an accessory like this will be.

  • Zaatour36

    Mugen batteries are wayyy pricy for an after market!

    And the fact that they are located in HK, doesn't give me the confidence to buy it even if I don't mind the price tag.

    I know that they are a reputable company with many positive video/written reviews, but I can't help it knowing when something is wrong or changed my minde, I won't be easy to return it back

    • Dude_Virus

      Buddy i am using a mugen 4800 for my dell streak and now looking forward to buy it for my note.. they are good batteries, i havent had any issues with the battery..seeing the battery i use even my friend bought one and he too is happy with the performance.

      • Zaatour36

        Interesting, so I might pull the trigger if I got the GS 3!

        thanks for the feedback

    • Sankeerths

      They provide 1year warranty and check xda forums u will see how other 5000mAh batteries are fake like hyperion.And moreover most of the gadget parts are made in china(Apple,Sony,Htc ) :P

      • Zaatour36

        WoW 1 year! I was looking everywhere for any information that leads me to the warranty period, but sadly didn't find it. Maybe i missed it!

        I think actually all of the gadgets one way or another are from China, but I meant the seller location, it would nice if they have a U.S. location or supplier.Also, I have a done a great deal of research for extended batteries, and most and not reliable enough, as they advertise more then what the actual capacity. Also, reviewers as well as blogs have a gave Mugen a good review, but the reason for me was the high prices!!

  • Misternagoya

    This battery looks actually pretty good, the cover is of better quality then the original and it feels better in the hand. The extra power is really awesome, 4 hours of video watching, websurfing, screen on 100%, gps on, wifi on... and still loads of power left at the end of the day. You don't look cool? Wake up you geeks, nobody looks cool with a smart phone!

  • Jay

    Very funny article David!

    • UNF

      Wrong, this was not even slightly funny, unless you have no actual internal humour function. In fact, it was evidently written by an unoriginal brat with nothing better to do than idly toss more clickbait into the seething pool of fanboy spume that is this webs[h]ite.

      • http://www.androidpolice.com/ David Ruddock

        Fanboy spume? Somebody got out their thesaurus!

    Galaxy Note, please come to Verizon!  :(

  • Oliver Petruzel

    I'd rather just carry my standard-sized $25 backup battery that easily fits in my wallet... seriously, this Mugen battery brick is ridiculous.

  • Freak4Dell

    Um, no, you don't speak for everyone.

    If you're already carrying an enormous phone, a little extra thickness won't hurt. Especially when that little extra thickness provides a crap load of extra battery life.

  • Guest

    As if the note was not big enough..
    Personally, I'm not to fond of Mugen's extended battery's. Last I heard they were based in China and made in China. Not sure how safe it would be to have such a huge battery on a phone.

    • Dude_Virus

      It doesnt matter if they are made in china .... 90% of the electronics or parts are made in china. The note itself has parts made in china so adding a battery which is made in china to it wont harm. Moreover having personally owning one of the mugen for my dell streak i can say they are worth the cost and the extra thickness they bring

    • Sankeerths

      Mugen Provides 1 year warranty on there batteries :P

  • Herrick_17

    If you own a g.note you already really know its big, and you really know what it can do, and you really know that you need a high capacity battery. (

    Over used of really know? Because you must really know you need this battery. :)

  • Mrknifenut

    Were things that slow around the office that you had nothing better to come up with then trying to bash a company that gives you the option of having more portable power? Really pathetic of you...seriously.

    • http://www.androidpolice.com/ David Ruddock

      Yep, things were that slow, so I said to myself, "guess I'll bash Mugen today, they've had it easy for a while." And then I put on my bashing hat and completely destroyed their reputation and everything they stand for. Last I heard they had to shut down because the negative press was "just too much to bare."

      Also, your comment has hurt me so deeply that I've decided to just quit writing about Android, I feel so bad for what I've done that there's no way I can go on. Woe is me!

      • http://twitter.com/TeamAndIRC Justin Case

        Good, you should quit, no one cares about your opinion

        • http://www.theandroidsite.com benmarvin

          For punishment, David should have to review this battery and carry around the Galaxy Note till the extended battery dies, so about a month or so. I specifically want to hear about all the things strangers say to him and how it ruined the pockets on every pair of pants he owns.

          • http://www.androidpolice.com/ Artem Russakovskii

            Except he should carry it around his neck like a Flava Flav clock.

      • Mrknifenut

         Wow, what a pathetic person you are. As far as you quitting your "writing"...GOOD! Your article was terrible anyways!

    • http://www.androidpolice.com/ Artem Russakovskii

      I sent a note with a local pigeon to David to post about it in a serious way, but the pigeon got drunk on the way there and rewrote the note. What a jerk.

  • Dj Arsonizt

    another pointless rant about the note. go play in traffic Android police! fu*k off! :)

    • http://www.androidpolice.com/ David Ruddock

      Gee, another easily offended Galaxy Note fan, whoda thunk!

  • Angelot48

    hey its a big phone anyway..... and useless when out in the world with out power....so where are you coming from...... i have the mugden on a note.... so are you calling me a mug for buying it.... of course it's a choice and for me a choice that works well...... thank you...

     from what his page says he uses a droid bionic, which isn't much smaller than the galaxy note. The Droids are decently large phones to begin with. SO I'm not really sure what he's complaining about. Those that use their phones consistently, need the power for it to last, so you're not charging it every few hours, or daily. and..sadly, more power, means bigger.. when it comes to batteries. As a female, I have no problem with my phone seeming bulky(i have the htc rezound, with a.. mugen(gasp), extended battery).. im used to the bulk, i see no problem with it cause i have a purse, and dont stick things in pockets. I can see where guys, or others, would have a disadvantage trying to stuff it in a pocket, but  ah well, the sacrifices we must make. I wouldn't be so against Mugen, as a company, since most cell phones have an OEM extended battery anyway. Mugen just goes up from there.

  • Sankeerths

    First off all People who haven't used Mugen
    1.stop talking as if u have used 2.It Provides 1year warranty (dont worry )
    3.it will easily fit in ur pockets

     its  like kawasaki ninja 600r(2500mAh)  vs kawasaki ninja 1000r(5400mAh)
    kawasaki ninja 1000r does have more weight and more power then 600r
    i choose more weight and power :P

  • Iain

    You David are so behind the times, People want style yes but what's the point of a great phone if you cant use it. Chances are you sit by a pc all day so don't run the battery down quickly and have charging at the finger tips. Every review of an upcoming phone I've read contains many, many comments like: hope it has a big battery or something similar. I think people have the right to choose functionality over form if that's what they need and as such I am a fan of anyone who tries to help facilitate that choice. I commend Mugen for creating batteries that make smart phones more practical.

    My phone lasts a day if I'm lucky, but if I'm using its massive storage potential(64GB N900) to listen to music at work, read the latest news stories on lunch and maybe watch the odd vid and show a mate some photos, its dead by 5 which is unacceptable in my opinion. Bring on the big batteries!

  • papa

    I have ordered this battery and it rocks. however, has anyone put a protective sleeve or use it in a car mount to see is if will fit?

    Dude you stop. I am so tired of tired of this device fashion trend. I dont give a fuck about what people think about my device. I just want it to work. Stop complaining the internet is already filled with people like you that takes from actually being able to enjoy it.

  • Diesel

    There's nothing 'ugly' about it. That is something you are projecting on it. People used to carry around phones attached to car batteries basically. Marketing has tricked people into thinking slim is sexy...instead of actually making a phone last all day long.
