So after testing the Mugen Power extended batteries (see review here), we’re giving them away to readers who have the corresponding smartphones — SE Xperia X10, HTC Desire, LG Optimus 2X and HTC HD7.

Here’s all you need to do — leave a comment below indicating which of the 4 smartphones you use and why you want the extended battery from Mugen (costs between $50 to $110 each).
That’s it. We’ll randomly pick 2 winners and give them the corresponding batteries which we’ll announce on this post by Monday. Not a lot of people might qualify sire there’s a huge chance you can get one of these for free.
Go hit the comments to be included.
Updated: We have our two winners!
We randomly picked which battery to give away using random.org and we got the one for Xperia X10 and HTC HD7.
We then randomly picked which of those who commented got the batteries and picked these two:
– reikoku
– Franz
Please email me with your shipping address so I can send them out to you by Monday. Thanks!

I use HTC Desire. Since I am always on the go and I used to play games, and used to browsing the Internet while I am outside as well, extended batteries like Mugen will be of great help!

These batteries are a necessity for me, when going on on multi-day outdoor trips, on the mountains and the beach. I can surf the web, post photos instantly on facebook while out. It completes the power of the smartphones.

Goodluck to everyone! ^^

I currently have a Sony Ericsson Xperia X10.
The reason why I badly want this Mugen extended battery is because I basically use my phone for almost everything. Music, video streaming, browsing the world wide web over 3G & wifi. Sometimes, I also use this android phone to edit my lesson plan & powerpoint presentations which I will use for my classroom teaching. I do these things most of the time because my laptop is very heavy and I don’t bring it everyday. So I just use my android phone to do my research and those that I mentioned above. It will be really great if I have more juice for my phone for me to be more productive and of course, to be able to save energy. :)

I have an Xperia X10. I want the extended batteries so I don’t have to keep charging my phone every single day. I also don’t have to worry about my phone going dead if there’s an emergency.

LG Optimus 2X
I have a Battery consumption issue with my Optimus 2X – 1500mah is not enough for this phone. After 20 hours of moderate usage (3 widgets running on home screen, simple wall paper, very few services running, 300-500 SMS exchanges, 1-2 hours of Wi-Fi on with Market app downloading 2-5 apps, less than 30 minutes of talk time) my battery got drained.

Hi I’m using an LG Optimus 2x. Currently i’m a researcher and a neophyte developer of GPS application for Intelligent Transportation System in Manila. My needs of accessing the internet anywhere and testing a number of power hungry GPS applications in my phone when and where charger is not available are definitely good reasons why i need something that can extend my battery life up to 3 times which Mugen Power extended batteries can give. Thanks

LG Optimus 2X.
Battery life is my main gripe with LG Optimus 2X. I’m a heavy user and my phone is on WIFI most of the time. It barely makes it through the day. An extended battery life would be a godsend.

I’d love to have the Mugen battery for my HTC desire. It’ll be great for our weekend trips, when we go on treks, mountain climbing , long cycling trips, etc where no charging stations are available.

i have my htc desire and having Mugen extended battery will give me more time to talk to my “bebe” longer than 6 hours like my htc desire can manage to take for a continuous talk.
Hope i win!!!
She’ll be very happy more than I do. It will make Pampanga nearer for us.

HTC Desire
I am a Medical Intern and I have to be on duty some times for more that 36 hours. And during this time I rarely get chance to charge my Desire and eventually the battery dies. So if I get a Mugen Power Extended Battery, I think it would help me concentrate more on my patients rather than checking the remaining power percentage every now and then.

Oks na sana yung LG Optimus 2X ko kaso bad trip lang dahil ang bilis maubos ng baterya. Ayaw ko namang i-root para tanggalin yung mga LG bloatware apps (na malakas kumakain ng baterya) kase mawawala ang warranty. Sana man lang malutas na yung mga bugs sa parating Gingerbread update. Pero habang wala pa, sana pagbigyan ako ng tadhana at mabunot ang pangalan ko sa raffle na ito.

I want an extra battery because my HTC HD7’s measly 1230 mah battery can’t last all day due to my always-online presence. I wanted to maximize my phone by signing up for a Globe SuperSurf Plan 1799 but was disappointed to find out that my unlimited mobile internet was limited by my phone’s endurance. Don’t get me wrong, the HTC HD7 is great! But being always-on on Twitter, Facebook, and all that jazz has a price – a Mugen extra battery. ;-)
Tony says:

I would like an Optimus 2X Mugen.
Because it’s cooler to play Galaxy on Fire 2 without charger cable between your fingers.
And because it’s 330am and I’m browsing Yugatech on my 15 min break at less than 15% battery remaining.

HD7.
My HD7 is my partner at work. I am a Pediatrician and I use the phone to communicate to my patients and colleagues via SMS/chat/calls. Online drug references and medical apps are a big help.
Although I enjoy the benefits of a versatile smartphone, battery life has always been a problem. Mugen is truly an innovative solution. With it, my standard battery can become my back up battery!

My wife gave me an awesome Sony Ericsson XPERIA X10i however the battery has a defect an won’t last 24 hours with regular use. I don’t care if these Mugen batteries are bulky, as long as my phone gets the extra juice, its all that matters.
