After a week use I really like this Mugen 5500 mAh battery :) Yes, phone is about 2x thicker with this battery but corners are nicely rounded so its not so big issue - after all, I bought this battery for capacity, not thickness :) And Mugen provides enought capacity to get me throught day, when working and on free time. And I appreciate the quality that Mugen promises of their batteries. Unfortunately I'd have take one star off quality due the back cover, which I'd like to be more robust, sometimes it "bends" too easily.

Oh my God, my phone finally lasts through a work day :). I have tried juice packs, cable at work desk, external extended batteries. Nothing is as good as this Mugen battery extender.
Even at my 15% battery notification, I still have 30mins of heavy usage.
Mind you , I play games daily and this battery lasts the mile.
only on two days usage - 7:30am-20:00pm heavy usage gaming, AWESOME highly recommend and the back case has a bit of a grip to it which holds the phone nicely in your hand.
The pouch though, another story, funny looking and gigantic :) Looks like a cheap extra on the side.
Galaxy s4 works 4 days instead 1,5 with original battery!
Shipping was great. I had the battery within one week of ordering. This is our 4th Murgen battery and would not hesitate to buy another. Completely charges in 3 hours and lasts for 2 to 5 days depending on phone usage.
My original battery was always letting me down so I decided to purchase the extended battery.
What a difference!
I charged and drained it several times to bring it to its top efficiency and it is now lasting a couple of days at least with heavy use.
I access work emails constantly, so am a heavy user.
Hyvä akku Galaxy S4:een, nopea toimitus Suomeen. Kandee tilata, pystyy suosittelemaan!
First time I used a Mugen battery and I am totally happy with the product.
Not having to charge the phone every day was my main incentive to purchase this item, and I was not disappointed. Although I have not run the battery empty yet - I am certain it will easily last for two days of moderate use - possibly longer.
The only downside is that I cannot find a decent protective cover for the phone now - although the supplied pouch is okay and much appreciated, it's still a long way from having a user friendly protective casing. This however is a small price to pay for the extra power this battery supplies.
You will also need to purchase some universal mobile phone cradle if you want to use your phone in your car via a windscreen mount - the original mounts, designed for your phone, will not be suitable anymore due to the added dimensions. I didn't have any problems though finding various alternative mounts.
I dropped my phone twice, and you should be aware that due to the size and extra weight of the battery, it is more likely that on impact the cover and battery separates from the phone. So don't drop it (doh).
Unless the supplied phone stock-batteries improve in the future, I will happily purchase this product again for my next phone(s).
Using this battery almost a year, if you follow instructions for initial recharge then this battery is much better than ZL. I wasn't afraid about running off power much after having this battery while on long business trips.
I'v been using the Mugen Power Battery about 45 days and i'm very pleased to buy it.With the original battery i have to charge my phone everyday but now i don't charge my phone for 3 days.Thank you for making such a great product.
A little bit biger, so it's difficult to use but it's work really good
