Product speaks for itself


Worth the price

I717 user for a long time

The battery is excellent, and safe.
The instructions for conditioning are clear.
The Customer Service is outstanding.

The leather case - Well, it's high-quality leather, but I don't find it very useful. It would be much better if:
1. The top covered the full width of the phone instead of just about 1" at the center, to keep it reasonably dry when it rains - nobody expects to go scuba-diving with their phone.

2. If it had a belt clip.

Right now the leather case is tough to break-in, when it's brand new out of the box, but with these two additions, it would be worth the effort.

Also, Mugen, how about:

1. A charger for this battery?
2. A dock that could accommodate the phone WITH your extended battery and door?



great battery

22 May 2013


This battery adds an incredible amount of longevity to my Note. I am not a heavy user but I find I can go 3 days before even having to think about charging. I highly reccommend this battery. The extra bulk actually makes it fit in the hand better.


Update after 6 charge and usage Cycles

21 May 2013

Note717 user

I am really impressed with this battery. It holds up to the description and expectation. The battery is at 20 % after 28 hours of medium-heavy usage. If you travel, turn off the data and you will be amazed at how long the battery holds up.

I am now able to use the Note 1 to its maximum potential as a Phablet.

Under heavy -very heavy usage the battery will stay for about 12 hours which is way more than the stock battery due to which I had to keep a spare charger at home, in the car and at work and charged it twice a day. With MP I charge it ones a day.

Must buy if you travel or are a heavy user.
The quality and longevity of the charge offsets the weight of the phone.
Will provide another feed back after 6 week of usage.


Battery works as stated

14 May 2013

Note717 user

Received last night. After the first cycle of recharge and 3 hours of usage the battery is sitting at 91 %. Usually the stock battery runs down to 50 % of charge after 3 hours of usage.

Battery case is good quality and clings on to the phone body though not 100% perfect.

Delivery times: Takes about 10 days to reach from the day it was shipped out of Mugen warehouse/facility. if not in stock it will take longer to be shipped.

5 star for now and will update after 5 more cycles of charging and usage.


battery bueno

27 April 2013


The battery is good. Loses some efficacy over time, as others have stated, but it's still much better than stock. The cover doesn't fit perfectly - bottom left corner sticks out more than the other corners, but it stays on fine, even if dropped. The main problem was took over a month to get to Texas.


Great battery for the price

22 April 2013


Batt works great...back cover does nt fit quite right..does not completely snap in...would like another...would buy your battery again...thanks




9 January 2013


This battery is well worth the price. I don't have to worry about carrying around a charger now and just charge it while I'm sleeping, the way it's suppose to be. Plus I like the sturdiness of the back cover, it's much thicker and grippy than the stock. Good job Mugen!


Really Great Battery

26 December 2012


This is really one of the great batteries. I'm impressed with how longer I can go without having worry about charging my phone. Great Job Mugen.
