Anyone have some experience with the Mugen double life battery?

You get 5 hours moderate to heavy use on the G3? You either have apps that are draining your battery, or your screen is on permanently.
 
I get a day and a half out of my battery. I know that Facebook app likes to drain your battery.

Maybe he means he is getting 5 additional hours from the Mugen Double Life Battery thing.
 
I'm interested in the Mugen because day one I used my phone from 9am and it ran from 100% to 0% by 2pm. I should have said heavy use and don't think it's an ap/screen thing. Day two of moderate use it ran out by 8pm. The Mugen double life seems like a good idea since it doesn't block features like the zerolemon. Guess I really value the extra battery life since I'm still in the trade-in period and the compeditor phone has an extra hour of life. So, it's decision time.
 
If not experience with this Mugen, how about Mugen batteries on previous phones. Are they a reputable company? I was not able to contact anyone calling the number on their website. It was a google voice number that sent me to a mailbox.
 
Mugen are one of the most reputable names in mobile device aftermarket batteries. Just make sure you buy from a reputable seller.

Thanks Stevovr.
So, the picture on their website has four electrical pickups on the case as opposed to two on the oem case. Its says nfc ready. The word "ready" give me pause. Will I have to buy another piece to use NFC?
 
I haven't used Mugen for this phone but have for others and it is about the only brand that I will buy. On my Nexus 5 I tried products by Mugen, Limefuel and i-blason and had failures with multiple products from Limefuel and i-blason. The Mugen product worked like a champ.

You shouldn't have to. However, be cautious, as depending on your model of the G3, the contacts might not be in the right place to line up with the contacts on the case for NFC/Wireless charging.
 
So, if we take heavy use as on all the time, then the battery life seems on par with what is to be expected from 3,000mah.
