Juice it up!! Best battery cases for the iPhone 4 4s 5 5S Samsung S4 Note 2 Note 3
The recent smartphone's battery life isn’t bad, but it isn’t awesome, either. With careful use, you can make your phone’s battery last all day. If you want to work your phone hard, however, particularly when you’re traveling or otherwise away from places to recharge the device, you need a battery case. We’ve looked at many battery cases for the smart phones. All of them plug into your phone’s charging / lightning connector, and all of them work basically the same way: You charge the cases up by plugging them into a wall adapter or USB port, and you activate them when you want to start charging up your phone’s built-in battery. If your smart phone is inside a battery case and you plug in the case to recharge it, your phone recharges first, and only afterwards does the case start charging. The best phone "Battery cases" should be easy to toggle on and off, simple to charge, and capable of providing a good indication of how much battery life remains in the case.
