Not a miracle, but still perfect

26 August 2015


First - about the ordering itself: I had to wait for my order 2,5 months (!), which I was very angry about and was already prepared to write a mean review. However, customer service was really VERY nice and polite every time (both on the phone and per e-mail), kept appologizing (apparently there was an issue with the factory delivery), in the end they also offered money back. I was already thinking about that, but just out of curiosity I wanted to see for myself, why does everybody seem to go crazy about these products - so I kept waiting.
Second - the product itself: finally when I received my battery, I must say, it was really a pleasant surprise. Of course, it does not do wonders (like e.g. old Nokia phones, which stay on the battery for 6-7 days), but compared to what I experienced with my smartphone before, it's a paradise:
-my old battery used to die after 3 hours (!!!), even when not really heavily using the phone;
-even on stand-by it used to loose 10-15% per hour;
-when there was around 15% left, the phone used to freeze and switch off completely;
-when fully using the phone, I had to charge it 3-4 times a day and if there was no charger available I had to carry around 2 external batteries, just to be sure that I will have connection for 1 single day.
The new battery keeps the phone alive for more than 24 hours - current record is 42 hours (!), also with pretty active usage (calls, SMS, FB, games, GPS, WiFi, mail, Skype etc.). Also, even with 5% of the battery left I can be pretty sure, that I will still be able to make or receive a call, if needed - no more external batteries in my pocket. Long story short - love it!


Just wanted to leave a review (5 stars)

Maybe you might be intrigued by the number of 5 stars by every reviewers? (Thats why I left 1 star and see if they would post it) It's nearly 2 years since I bought it. I am so pleased with it that I just wanted to leave a review. The battery is rock solid, I get 2days+ on normal use using CyanogenMod. + its customer support is the best. Definitely recommended.

Just, received, it's charging now for the first time, when installed the battery, check the power was 53%, so spoke with some buddies, before plug the charging cord, for commence the all night first charge. The finish & quality of the battery & back cover it's SUPERBLY. Surely, I that will kept my Samsung S3, white color, fitted with the Mugen battery & back cover, for a long time.

Highly recommended!.



Bonne qualité générale

26 June 2014


La batterie est de bonne qualité, malgré que le gsm devient plus gros le look reste génial.
Un seul bémol, malgré l'étui offert d’excellente qualité, son encombrement est selon moi trop grand, cela double carrément la taille du Gsm ce qui est très dommage pour un homme que le met en général en poche !!
