There are two versions of this battery, one for the N7000 and one for the I717 - i have updated the OP with the link for the I717 so you buy the correct one

Amazing work, amazing write-up. The best battery review i've seen yet.

Im glad to be of service

Edit: P.S. The only thing thats keeping me from jumping through your screen and dancing is the lack of runtime data. Maybe MaH ratings are good for engineers. But runtime data is much easier to interpret. Because from the chart above, it seems that the battery is rated at 200% the capacity of the OEM battery, yet is only provides a certain percentage of that expected capacity. Is this what your chart is explaining? Sorry. It's late.

The reason i didnt do runtime data was that there is no standard test - mah is a much more scientific way to work out capacities - i can tell you though that on screen-full-brightness-test it surpassed 6 hours

i agree, the kickstand is a fantastic addition

It took 26 hours from 100% charge to 10% remaining with screen at 100%, either on wifi or 4G, with pretty much all the back ground stuff enable. I surfed, gamed, watched two complete movies and 3 episodes of Battlestar Galactica (wife was doing her scrap booking "fun" with her girlfriends and I had access to free wireless), checking e-mail, fiddle farting around trying to get it down to 10% faster. Charges to 100% fairly quickly, I plug it into 110 v around 2230'ish and has full charge when I wake up at 0600.

Was it a bit on the high side of cost??? Yes, but don't regret it at all, has been great not looking for an outlet every where I go, not rushing to connect to my charger (actually have not use my charger since I installed extended battery) and having to carry a plug and USB cord with me every time I leave the house.

Highly recommend.

I agree, a very worthwhile product

feel free to ask any questions about the product guys

My 5400 mAh Mugen battery arrived this afternoon. The order was placed on the evening of June 4, so it took a week for it to arrive in Toronto. Pretty good for free shipping from Hong Kong!

I'm just charging it up now, so nothing to report on so far. I will be on the road tomorrow, so I'll try running 4G+GPS+BT with Google Navigation while in the car (about 70 minutes travel time total), and Ethernet while on-site with a client. Screen brightness will be at 100% the whole time. If I can get through an entire day without the battery dying, I'll be very impressed.

I really like the much grippier, textured back. No need for me to take photos of how it looks, since panyan did such a great job. Kudos to Mugen for using packaging that is EASY to open! No knives or scissors or personal injury involved here. Just snap the two halves apart, and out pops the battery and cover!

^im glad your happy

ill be interested to see a screenshot of your battery usage after that epic trip

Great review, but at $100 dollars, the price seems too steep for just a battery... $50 probably would have been more reasonable

at first this was my thought too, but when i thought more about it:

we have all paid a great deal of money for our devices and when theyre out of battery, they are as good as useless... this product keeps our device running much longer and therefore is worth more than "just a battery" - if you see what i mean

$100 is on the expensive end of the spectrum, but it is reasonable considering the capacity, the convenience, the special back cover, the cost of the 2650 mAh battery, and the likely lower sales volume of the 5400 mAh part. If Mugen had been contracted by Samsung to produce a million units per month, they might sell it for $75 each... but then Samsung would retail it for $100 anyway.

You could buy two of the 2650 mAh batteries for $94. For an extra $5, you get just as much capacity, and a bonus kickstand cover with a better grip surface. Two batteries means I have to shut down the phone, pry off the cover, swap the battery, snap the cover back on, and reboot the phone. The convenience of simply having it all in one battery is worth it to me.

^ agreed



just so you know guys - im on its 20th cycle and it is still giving me the same screen on time
