For those who want more battery life out of their phones, there are charging cases. The most recognizable brand of charging cases is mophie, who offers a wide selection of charging cases and portable chargers for a variety of devices including Apple devices and certain Samsung devices. Mophie offers different cases, each with their own advantages and disadvantages, such as the juice pack air that adds an extra 100% battery but comes at the cost of being bulkier than other cases and the juice pack H2PRO which is one of mophie’s bulkiest cases. It also provides an extra 100% battery life as well as waterproof protection. Apple also sells charging cases designed specifically for iPhones.
