Excellent Battery!

18 July 2013


This is my second Mugen Power battery and it works great! These batteries are a great remedy for Android battery life woes!


Worth Every Penny

1 February 2013


Short and simple: buying this battery gave me full use of my phone!

I've had this battery for about a month now, and my phone now regularly lasts me a full a day of heavy usage (at least 3hrs talk time, 2.5 hours of emulator games, Facebook, Google+, texting, 1 hr of Bluetooth audio streaming, and about 9 hours of idle time)! I no longer carry extra chargers/cables and I no longer worry about whether my phone is going to last the rest of the day or not!

I love my phone again :-)


Excellent Results Worth Every Dollar

Received battery yesterday with initialization instructions, battery door, and a free carrying case. Couldn't be happier. Even with my phone hunting for service all the time I have used only 6% of the battery in the past 4 hours even with moderate use. Really fantastic. Cannot even elaborate on how satisfied I am. Shipping was dreadfully slow but well worth the wait. I no longer feel scared leaving the house without a USB cable and charger and I have stopped using my car charger. No more turning the ignition on and connecting my phone to the charger. Phone shows 28 hours remaining of battery life using Gsam App. If you have any reservation spending the 90 bucks on this please don't hesitate any longer. This is by far the best extended battery I have ever owned. The battery door (cover) is also excellent. It fits snugly just like the OEM door. Haven't made my mind up on the kick stand; it's made of cheap plastic however in previous experiences I felt somewhat fearful of my old HTC with the metal one because if something got caught on the kickstand it was really the strongest piece of the phone and would do some damage so I can say I do appreciate the benefit of it being plastic on this door. The hinge is made pretty well on this and does not weeble wobble even when pressure is applied. Fantastic job. Excellent Quality. No longer skeptical.


beleive it

it's only been two-three weeks in use...but this battery has completely accomplished what it advertises. Emails, uploading/downloading, FB'ing,Youtubing, etc - No regrets with this purchase!


Samsung Galaxy Verizon 3900mah Battery

2 June 2012


Simply amazing! Didn't expect it to be that good. Even with heavy use of video, gps and email, have to charge only once a day. Lasts morning 6am till 11pm with about 20% still remaining. I use it for work and have come to absolutely love this battery and the phone as a result. The stock battery that comes with the phone is garbage and Mugen battery is worth every penny spent.


Mugen battery is the Best!!!!
