Very powerfull battery but too thick.

10 May 2015

Kees Kuijstermans

My S5 looks like an early nineties mobile phone now: it's twice as thick with the new battery.
But I must say it's a very powerful battery.
It provides energy at least twice as long as the original battery.


I'm very happy with it

10 May 2015


Gives me 2 full days with heavy usage, over 11hrs of screen on time. It's twice the life of the original battery. Waterproofing looks good but I haven't tested it submerged


Great, but here are some suggestions.

Great Product. This is my second Mugen battery in the past couple of years, new since changing phones. I waited for Mugen to come out with the Qi charging for my GalS5 so i don't have to plug in anymore. Would be even better with a slight bumper. I have looked for a bumper to come out and just cant find one.
Also, For the next Extended battery, find a way to make the overall product slimmer by spreading the battery around more or make it more curved around the edges so it fits in my hands better.


Top product, as usual.

This is my third extended battery from Mugen Power for each of my Samsung Galaxy mobile phones as they have been updated. Excellent product each time and no exception on this one for the Galaxy S5. My usage pattern returns a threefold increase in battery time, meaning a recharge every three days instead every day. Brilliant product that delivers everything promised. Thank you MP. GK


Outstanding battery/backcover

31 January 2015


Mugen appears to be the only company (from google search) that has an extended battery AND wireless charging.


On the website, the backcover was not suppose to be IP67 water-resistant (they were working on that, but it wasn't suppose to be wireless charging capable. The model I received is!

Wireless charging: Worked effortlessly on the Qi charger I was using with a wireless charging card.

NFC: Worked perfectly.

Design: Very solid and well designed. The wireless connector is solid, the speaker is boxed in, so that sound won't echo in the hollow space, but is directed to the cut-out. Also, the speaker cut-out has a film cover, which the OEM does not. I'm used to having my phone is a case so I'm used to a larger feel in my hand and it feels very comfortable to me.


Just one. It would be nice if it included a bumper so that the front of the phone was raised slightly. That being said, Mugen included both a tempered glass screen protector, and a leather-like pouch for the phone. I honestly don't know if that's part of the standard order, but it was a very nice touch.

Lastly, Mugen is based out of Hong Kong, but they are by no means anything like an e-bay cheapy product. Instructions included with battery are written in perfect english. If you've ever gotten an e-bay product from the Far East, I'm sure you know what I mean!


S5 extended battery

8 January 2015


Great product. I used Mugen batteries since my first QTEK. With this S5 battery I received a black battery cover instead of gold (as I ordered), but this is a small minus.

Спасибо , доволен


very good product, excellent battery

Livio Bottiglieri

Extended battery is excellent, its cover fits perfectly my S5; duration is triplicated if compared to original one. the battery has its complete recharging in about three hours; recommended item for S5 hard-users.


достойная вещь

20 November 2014


Еще до покупки телефона увидел эту батарею и захотел ее приобрести, смущали только размеры.
Заказал, наконец-то пришла. Но телефон с ней в руке лежит только лучше т.к. он перестал быть тонким и держать его стало удобнее.
По автономности полностью устраивает: без игр, только вайбер, ватсап, звонки и немного интернета держит 5 суток; с играми по 3-4 часа в день держит 2 дня. замечательный продукт


Outstanding and well worth the price

19 November 2014


I am a sales rep who works on the road all day (and sometimes into the evening), and my number one issue with modern smartphones is battery. I'm willing to sacrifice many things for a phone I can use all day without constantly checking my charge and searching for an outlet.

With this battery, my dreams are fulfilled. First of all, do not be intimidated by the bump the larger battery adds. If you're using the S5 active, you've already said you value function over form. Second, it's not a pronounced bump. It adds some slight heft, but if you add a bumper style case, it smooths out the protusion and makes it pretty seamless. My friend has the regular S5 in an otterbox case, and her phone is fatter than mine with the excess battery.

As for performance, this battery is noting short of a beast. As I sit typing this, I started my day at 6 a.m.; 5 hours of heavy usage later I'm still at 89%. I no longer worry about using GPS heavily, or streaming music while driving. I don't worry about anything, because I don't think it's possible to drain this battery in less than two days. Forgetting to charge overnight used to be a death sentence for my phone; now it's no big deal.

This is an outstanding product, and has increased the usefulness of my S5 Active tenfold.
