Fact: We’ll never be satisfied with the battery life of a phone. Even in some distant future we’ll be like, “This thing only stays on for seven months?! What a piece of junk.” When you’ve got Twitter feeds, pages of apps and texts to fire off your iPhone battery can die quicker than the hot girl in a horror movie. Luckily, there’s the Juice Pack Reserve from mophie. Keep it on your keyring and give your iPhone battery (or iPod battery if you’re just rocking out) a quick shot of adrenaline. The high-output battery allows for super fast charging and there are zero cables needed to use it. Just remember that it is going to be a tad tougher to tell your wife or girlfriend that you didn’t call because your battery died.
