The battery is great, the cover is a little bit weak- those plastic pins are easy to be broken. And the case doesn`t fit at all. But the battery is the best one I tried!


Very good product

This is a kickass product. More than twice the original battery with a a case that just clips and fits into place with no problems.


Very satisfied

8 October 2013


Product is excellent as described. What i loved was that the cover just fitted without a hassle . Would suggest 100%


2x is really 2x

If I were to use the stock 1700mAH battery, if on a normal day usage on 3G, i would have to charge it by lunch time. On Mugen's 4000mAH battery, it'll last me until I go to bed, which is around 11pm!


Excellent product

9 July 2013


I've been using the battery for a good six months now, and I can say that I'm fully satisfied with its performance.

As previous reviewers have already said, this battery at least doubles your phone's endurance. On a full charge I can easily get 2-3 days (50-70 hours) of moderate use. Even under heavy use the battery can last for a whole day (24 hours).

Battery door's a bit flimsy, especially the kickstand part. Mine's already somewhat damaged. But the great news is Mugen has shipped me a new one at no extra cost. Talk about customer service!

I hope Mugen sticks around for a long time. I fear the day when all phone manufacturers decide to make their phone batteries non-removable (which is true nowadays for almost all the top brands).


great battery,but

22 May 2013


Great battery, but low quality case



16 October 2012


Good fitting case, at least double the standard battery life. Could do without the kickstand, it catches on things and can get in the way.
All I need now is a pouch holder that will fit !

Good product high recommented.
Excellent service


More than doubled the lifespan of the stock battery

Starting for the outside in, the battery cover that is supplied fits like a glove. It snaps in very easily for a snug fit. It does add a decent amount to the dimensions of the phone but it doesn't feel bulky and it's not a huge compromise considering the return you get. There is a kickstand that is supplied with the cover and I find that to be more of an annoyance as the hinge loosens up after about a week and it occasionally decides to just pop out every once in a while.

The battery itself works wonderfully. Mine came with a 25% charge and I plugged it in and left it charging for 8 hours as the instructions said to. I repeated the 8 hour charge cycle for the first 4 charges as the instructions also mentioned. The battery now lasts for a good 2 days, sometimes even 3, depending on the usage. I use a decent amount of power consuming apps (BBC, Reddit, Youtube, Twitter, Airdroid, Grooveshark, Dropbox etc.) everyday and the battery holds up well.

I am satisfied to say the least. If only that God damn kickstand would stay in its slot.


Battery good, delivery as promised but some issues with the cover.

2 September 2012


Having used it now I say it has improved my phone alot. I no longer run out of power before the end of the day and its not too clunky, it still fits in my pocket.

It was not easy to get the cover to snap in, always some corner did not lock tight. After a few tries and much closer examination och hinges and haches I got all corners in and it now sits perfectly.

There was a latch, leg or something on the back side. Was it there for helping in taking the cover of or was some other feature? I don't know. This has already fallen of. I just hope it was nothing vital.
