Fantastic Power
I purchased this item because I was fed up of having to try and provide extra power when out and about. I have already tried all the other options, inc carrying several spare battery's, but this is superb the extra power is provides is fantastic and no more worries about running out while I am out. yes it adds a bit of weight and size to the unit but it is certainly worth it. I just need to find a new case for it now.

Helpful Ancillary
Vrey effective for much longer time before battery runs low. Downside is much more bulky Regrettably at the time I bought this Mobile Fun did not have an appropiate case for device with bulky back on it. Much better than fiddling about with battery conserving apps, which have their own downsides.

Extended battery adds 2500mAh to your Galaxy S3

The original Samsung Galaxy S3 battery is 2100mAh, this Mugen battery is an impressive 4600mAh. Adding 2500mAh, more than enough to give you that extra time you need to chat text or surf.

Built in NFC chip to use Samsung TecTiles

The Mugen extended battery features a built in NFC chip which gives your Samsung Galaxy S3 its NFC capabilities to use NFC technology on items such as Samsung TecTiles, programmable NFC tags which let you immediately launch apps, send text messages and change phone settings as well as many other things.

Includes replacement back cover with stand

Because this battery is so much bigger in capacity than the standard one, it also has to be bigger in size. To accomodate this, the battery comes with a specially built replacement back cover that houses the battery, while also offering additional protection to the back of your phone from scratches and scrapes.

Additionally, the cover also includes a unique stand which allows you to place your phone in a horizontal orientation for watching videos and displaying photos.

Guaranteed for one year

The cells used for these Mugen batteries are of such high quality, they are guaranteed for one year. Something other manufacturers don't do.
