If there's one thing smartphones still fail to offer customers, it's long battery life that negates the need of charging a device every night (or every afternoon or evening for those devices with really bad battery life). That's where extended batteries and battery packs come in, and now Galaxy S4 owners can extend their phone's battery life with the Mophie Juice Pack.
The Mophie Juice Pack is basically a case with an inbuilt battery, which charges your phone to extend its usage times. The S4 Juice Pack comes with a 2,300mAh battery (~80% of the standard S4 battery), and will add 13 hours of talk time, 6 hours of browsing, 35 hours of audio playback and 7 hours of video playback to the phone. A 4 LED indicator gives you the status of the battery, and the phone can be charged and synced without having to take it out of the case.
The Mophie Juice Pack costs $99.99, and you can check it out at the source link.
