Excellent product

15 October 2013


It was was exactly what I needed. I used it extensively for a 7-hours run hike, using my phone as a GPS navigation device. The phone was still operational several hours later...
Overall, it is not so heavy nor so bulky


super battery

4 December 2011


excellent battery
it lasted 6days when the original lasted in 2days
with the same use
i will give an example
6days use=130minutes phone calls and 40minutes wifi
if you have always the wifi and gps on it wont last that long

I purchased a second hand Nexus S and the original battery lasted for max 10 hrs. After installing Mugen battery it took me some 11 days to format it and now it keeps my phone up and running for 2.5 days in average (regular use - gprs online all the time, 20 - 30 minutes of gaming, a bit of YM chatting, a bit of GPS, couple of pictures, some 20-30 minutes of voice calls, 10 minutes of Skype with video etc etc). And if I do not use the phone too much it can survive 3 days on a single charge - and still keeping above 10%.

Well, on the dark side, the phone is not that slim anymore and the door falls off easily when you accidentally drop the phone onto a hard surface so you need to be more careful. But this is compensated by long life of the battery for sure.

Final opinion: Great value for the money. I will definitely buy another Mugen battery when I switch to a new smartphone.


Lasts all day

If an app is not accidentally left on battery last all day. Just what I wanted. My old purple protector no longer fits and it would be nice if one was available that would fit the new cover.
