Samsung Galaxy S3 fans now have an additional option  to increase the battery life of their smartphone, courtesy a battery case called the Mophie Juice Pack.

With smartphones becoming an indispensable part of our day-to-day lives, the constant usage makes one wish that the device had more battery life. It can be argued that one can carry around extra batteries, but that becomes cumbersome and that is where the Mophie Juice Pack, a case with a built-in battery becomes a savior.

Mophie is an award-winning California-based company, which manufacturers and designs mobile intelligent devices and accessories.

"Get the most out of your Samsung Galaxy S® III with the mophie juice pack®. This durable, ultra-thin case houses a rechargeable battery that virtually doubles your time to rock, talk, surf and send," notes the Mophie Web site. 

The Juice Pack for the Galaxy S3 is priced at $99.95 and is available in two colors: black and white. The Juice Pack includes a rechargeable 2300mAh battery, which provides an additional 9 hours of talk time on 3G, up to 9 hours of additional Internet usage on 4G, and up to 11 hours of extra Wi-Fi Internet usage. What's more, the Juice Pack gives users up to 32 hours and 8 hours of additional audio and video playback, respectively, without compromising on any of the phones' features.

The Galaxy S3 packs in a 2100mAh battery and supports 10.8 hours of talk time on 3G.

The Juice Pack, with its 2300mAh battery will double the device's battery performance. Additionally, the Mophie Juice Pack includes a four-light LED indicator. Moreover, both the Galaxy S3 and the Juice Pack can be charged using the microUSB cable which is included.

"As one of the thinnest S III battery cases on the market, the juice pack was created with you in mind. It provides a comfortable, ergonomic design while fully protecting your phone and a toggle switch allows you to charge only when you need it. It's also completely S Beam and NFC compatible, so don't worry about us getting in the way of sharing with your friends," states the Web site.

The Juice Pack also lets users access all ports, speakers, and controls without any hassles. The case is also S Beam and NFC compatible, which means that users can share files or make payments via NFC without needing to physically remove the case.

The Juice Pack is a viable option for users who use a case for their Galaxy S3. Even though the battery case at $99.95 is an expensive option, when compared to buying a second battery, the benefits the Juice Pack offers may well justify its steep pricing.
