If you picked up an HTC One and found that its battery isn't quite cutting it, Mophie may have a solution for your dilemma. The accessory maker is now offering its popular extended battery line for HTC's crown jewel. In addition to its slim protective casing, the freshly minted Juice Pack keeps the party going with an embedded 2,500mAh backup cell. Mophie claims that its added pick me up can increase the One's battery life by two-fold, placing its performance on a par with the marathon-ready RAZR MAXX HD. Available in two colors to match whichever hue you're sporting, the $100 Juice Pack is a surprisingly attractive backup plan for HTC's aluminum marvel.
