The Samsung Galaxy S4 comes with a really great battery. With just one lithium ion 2600 mAh battery, the Galaxy S4 lasts through most days, no problem. But you still have to charge the phone every night, and if you forget, then your day is full of checking the battery level and looking for a place to plug in your charger for a moment.
That's what extra juice packs and battery extenders are there for, and the Samsung Galaxy S4 just got a great new one. Mophie is probably best known for its juice packs for the iPhone, but the company is now releasing a solution for low batteries on the Galaxy S4 as well.
The Mophie "juice pack" extra battery case and charger is just under $100 and comes in white or black. It's both a protective case and a 2,300 mAh battery that can flip on to charge the Galaxy S4 whenever its own battery gets too low. At 2,300 mAh, that's about 80 percent of the Galaxy S4's, and will add about 13 hours of talk time, six hours of online browsing, 35 hours of audio playback, and seven hours of video watching, according to SamMobile.
The only downside for the juice pack is that it will add quite a bit of thickness to the incredibly thin S4 - more than doubling the thickness from under a third of an inch to two thirds of an inch, at 0.66-inches. Still, with an extra battery capacity like the juice pack, you'll probably be fine from now on, as long as you remember to charge your Mophie-enhanced Galaxy S4 a few times a week. And the juice pack seamlessly blends with the aesthetics of the Galaxy S4, simply making the S4 look a little bit plumper. Here's the promotional video for the Mophie juice pack:
