Good product

23 August 2015


A good battery: i've waited almost 2 months (shipped to Italy) and loaded according the instructions; it lasts a few more than an original battery, much lot more than a non-samsung common battery



24 June 2014


Spedizione velocissima, arrivata in Italia in 3 giorni lavorativi. La batteria funziona bene e garantisce un 20% di durata in più rispetto l'originale. Consigliata.


Fast delivery, great service

The Mugen battery for my Samsung S3 keep the power twice compared to the original.


Like a new set of legs

9 August 2013


My phone has recovered its stamina. Like a new set of legs, this battery has gotten me back to a full day of worry free power. I can even play games without worrying about taking too much power.

I give thanks to Mugen Power for a powerful product, quick responses to my questions, and peace of mind.



10 July 2013


This is not my first Mugen battery. I am as pleased with the quality of this one as my previous purchases. Supposedly OEM batteries can be purchased online for much less, but I have found most are cheap copies that are poor quality.



23 May 2013


Improved my S3 use time in 20% wich is nice.
