This is the LG G3, one of the best smartphones for 2014. It hasn’t really received a whole lot of attention lately because there has been a ton of new flagship smartphones released not too long ago. But if you guys remember, the LG G3 has a rather large 3000mAh battery. It requires a lot of juice due to its high end component so you can get about a day of use out of this phone.

Well, this is the Mugen Power LG G3 Extended Battery. It’s a 6200mAh battery that significantly improves battery life. In fact, it can last more than two times as long, which is crazy.

Now with such a big battery, there comes some sacrifices. The first is that it adds a considerable amount of bulk to the G3. With the stock battery, it’s a pretty slim device coming in at 8.9mm thick whereas with the extended battery, it’s going to be twice that size. And there’s no question it adds a significant amount of bulk to the device, especially in the hands. It just feels much more substantial both through its physical size and it also weighs quite a bit more as well.

Mugen does provide additional cases with the extended battery because if it didn’t, you wouldn’t be able to pop on the original back cover. It just wouldn’t fit. And these covers range from gold, white and black as you can see here. And they feel a little bit different than the LG G3’s back cover. They’re a bit more slimy feeling since they’re made of plastic whereas the original LG G3 cover is made of plastic but it’s brushed and smoothed down to make it feel like metal. So overall, the cases for the extended battery feel cheaper than the LG G3 and its stock back cover. But not by a whole lot since they are both made of plastic.

And these custom cases still do feature an NFC wireless charging support, both of which just work fine. The G Wireless charging won’t work on the AT&T power mat however so you’re definitely going to want to keep that in mind. What’s cool though and rather useful is the included kickstand, which is actually indented into the case. All you have to do is pop it up and you can prop it up and watch videos. The only problem is that you can’t really navigate your device with a kickstand ejected. It just really isn’t positioned to support the use of the touch screen. It’ll just fall over. But once you have a movie or video set up, it will work just fine on a flat or sturdy surface.

There’s also cutouts for all the rear-facing buttons. Mugen did do a great job up here and that the cutouts fit perfectly with the camera and rear-facing buttons. And you can easily reach them with no problems at all.

But I’ve been testing this battery out for the past couple of weeks and it’s really amazing how long it lasts. The standby time is excellent. You can literally leave this phone on and it’ll stay on for about a week just on standby. And if you use this phone moderately, like myself, you’ll get about 3-4 days of use out of it give or take, depending on how much you actually use your phone.

So overall, if you play a lot of games, watch a lot of videos, maybe you just like to use your phone at full brightness with all the bells and whistles enabled, then you’re going to seriously want to consider the extended battery since you’ll be able to use this phone for, like I said, more than twice as long as you normally would before you’d have to plug it into a charger.

If you guys want to check out more details about this product, I’ll leave a link for you to do so down below the description bar. It costs right around $90 but could seriously be worth it to you, if you value using your LG G3 for longer periods of time.
