\r\n\r\nA common complaint\u00a0among\u00a0iPhone users is the rate at which the battery drains. Regardless of whether it's poor design by Apple to not include a larger, more powerful battery, or simply a result of increased usage of an amazing device, seeing the low battery warning on your iPhone is troublesome. In an effort to satiate consumer demand for extended iPhone battery life, several companies have developed iPhone cases which double as an external battery pack. These cases can breathe hours, if not days, of additional juice into your iPhone. Here\u2019s a list of some of the exciting products that were showcased at CES 2013.\r\n10. Esorun BC01 iPhone 5 Battery Case\r\n\r\n\r\nThe Esorun BC01 battery case not only charges your iPhone 5, but comes with a cool stand and functions as a protection case, providing users a well-rounded case that does it all. It features a built-in 3,000 mAh Li-polymer batter that is said to practically triple the iPhone 5's battery life. So far no price has been announced yet, but it will be available mid-February.\r\n9. PowerSkin Pro\u00a0iPhone 5\u00a0Battery Case\r\n\r\n\r\nI like my iPhone battery cases like I like my women: thin and powerful. Just kidding. The PowerSkin Pro iPhone 5 battery case is incredibly thin, durable, and full of power. The case, constructed of a double-injected TPU material and enveloped in a hard plastic shell will protect your precious iPhone, while the 2,000 mAh battery will provide plenty of on-the-go juice. The case features a front-end LED battery level indicator and will come in five colors- white, black, titanium, red, and pink.\r\n8. Tylt Energi iPhone 5 Battery Case\r\n\r\n\r\nThis product is a case within a case. Inception? This two case configuration is Tylt\u2019s attempt at making battery cases as thin as possible. The first case is called the Presto. It\u2019s a slim, hardshell case which provides day-to-day protection. When you get the dreaded low battery notification, simply slide the Presto case into the battery case where your iPhone will be greeted by a 2,500 mAh battery.\r\n7. iBattz iPhone 5 Battery Cases\r\n\r\n\r\niBattz is no stranger when it comes to iPhone battery cases. This year at CES they unveiled a few products that will not disappoint. First up is the Mojo Refuel. Unlike other battery cases that have a permanent battery, the Mojo Refuel allows the user to swap out the rechargeable battery simply by removing the back plate. The Mojo Refuel comes with two interchangeable 2,200 mAh batteries and will be made available in February.\r\n\r\nAnother awesome product by iBattz is the Mojo Armor. This case is similar to the Mojo Refuel but offers more in the protection department. It has a dual-material shell (think Otterbox) which provides more protection against accidental drops. Just like its cousin, the Mojo Refuel, the Mojo Armor allows for battery swapping and comes with two 2,200 mAh batteries. This case is slated to be released in March.\r\n6. uNu\u00a0DX Protective iPhone 5 Battery Case\r\n\r\n\r\nuNu had a really popular iPhone 4 battery case and is following up that success with what looks like another promising iPhone battery case. uNu\u2019s DX Protective Battery Case for the iPhone 5 is amazingly thin, adding only 15mm in thickness, and is comfortable when held. The case provides easy access to the iPhone\u2019s ports and switches, including the headphone jack, and features a 2,300 mAh battery which will provide an additional ten hours of talk time.\r\n5. Joy Factory\u2019s Ergos iPhone Battery Cases\r\n\r\n\r\nLow profile. Thin form. Kickstand. 2,100 mAh battery. What more do you need? The Ergos by Joy Factory is a pretty simple case that offers the basic necessities of an iPhone battery case (protection and juice). What sets this case apart from the others is its kickstand feature. The kickstand is a foldable appendage that allows for easy hands-free viewing. Joy Factory is also offering a similar case with no kickstand. Prices are set to be $89.99 and $79.99 respectively.\r\n4.
