Awesome Battery Upgrade for Q10 4400mah

18 June 2015


As my stock blackberry Q10 battery died, i decided to go for the extended 4400mah. It lasts for 2 days as advertised. No more switching to 2g to save battery life. It adds a bit of a bulk but its worth it


brilliant product

27 May 2014


Excellent battery pack. Great look. Extended life. Reaches its maximum capacity after three or four full recharges. I am a very heavy user on calls and data ALL day and in 12 hours my battery level reaches 40%


Amazing product \ produit incroyable

More than double the original battery capacity ! My Blackberry Q10 become a real workhorse now...
La capacité est + que doublée par rapport à la batterie originale ! Mon Blackberry devient une vraie bête de travail maintenant.


Very Happy - worth the price

3 January 2014


Purchased 3. One for me, my husband and my business partner. Very happy with the life on the battery. I like the extra weight on the phone because it gives it stability and the quality of the battery door is impressive.


Worth considering

31 December 2013

Q10 business user

I was steadily complaining about Q10 stock battery that was not reaching 24 hours and I have decided to give a try (4400mAh).

It adds a "hump" at phone' s back as described but you can easily live with it.

It even puts some extra weight that adds a bit more stability while you type, but this will depend on the size of your palm (mine is 9-1/2). If you have small hands, you may think otherwise.

It could last about three times more than original battery.

My useage profile is heavy e-mailing & texting, frequent whatsapp & browser use, sometimes mobile hotspot for my laptop.

I do not use this device for gaming.

There is only one point : OtterBox does not have a commuter case for the resulting Mugen geometry :-)

I recommend this to Q10 users.


Issues with Instructions & Calibration with Blackberry Q10

27 November 2013


I have purchased numerous Mugen batteries in the past. They have always worked well and lasted longer with respect to recharge cycles than any other batteries I have tried. This includes the OEM versions … which are nowhere near as good as Mugen.

However, there are some good and not so good comments about the latest battery i purchased and how it performs with a Blackberry.

The instructions state that the battery will not calibrate with a Blackberry Q10 … which I found to be true.

However, an insert that came with the battery states that you should NOT use the battery beyond 0% as it will do harm to the battery and reduce its useable life.

What they really mean, after talking to Mugen tech support … is that you should not use it beyond the point where the phone turns off. This is not at all clear in the instructions .

The instructions state that when the battery reads 0% on the Blackberry, it is not depleted. It will still power the phone for much longer … I assume twice as long as the stock battery.

Mugen says to use the battery until the phone turns off and then recharge.

This is a problem for me as I do not really know the state or condition of the battery and I cannot be without my phone since it is my primary business line.

One good thing i found which I was worried about is that the antenna in the battery cover seems to outperform the stock Blackberry antenna by a small but noticeable amount.

I gave the product 3 stars because the issues seems to be out of the control of Mugen and it appears to be a Blackberry related issue.

However, if I had know this prior to purchasing the battery, I would have stuck with my standard battery and recharged as needed.

I cannot afford to have my phone die unexpectedly … so I find that I recharge the Mugen just as often since it is not reading accurately and telling me it is at 0% when it is not.
