Talking, texting, emailing: You do it all on your smartphone. Work, family, social life: You grab your iPhone 6 to manage all aspects of them. Your device is in constant peril, and so is your battery life. So, to take care of wear and tear of your ever depleting battery, clever inventors have come up with a dual solution: iPhone 6 cases that both protect your device and help those battery bars disappear a little slower.

Cases-cum-extended battery packs are becoming more popular. Let take a close look at a few of that are turning heads online:

  • One classic option comes from i-Blason with its iPhone 6 4.7 UnityPower Rechargeable External Battery Case.

    Its "external, rechargeable battery allows you to charge your iPhone to 100 percent battery capacity while working, shopping or traveling," the manufacturer said.

    The case features an 3200 mAh capacity polymer-lithium battery.

    Currently, it is only available in black and for the standard iPhone 6 model, and your added protection and battery life will set you back $79.99.

  • If you are looking for a less expensive option, you may want to put the $45.95 Alpatronix BX140 iPhone 6 Battery Charging Case on your list. Its rechargeable 3100 mAh battery effectively promises to adds a "150 percent charge to your iPhone 6 to last you the entire day," while its "ultra slim hard shell encasing provides complete protection and minimizes bulk."

    This case comes in no fewer than 10 different color combinations, though it, too, is only available for the standard iPhone 6.

  • If you are the proud owner of an iPhone 6 Plus, you can still boost your battery with one of these special cases, such as the MOTA Extended Battery Case. It "provides fast charging speed (2400 mAh), doubling your battery life," according to the manufacturer, and it is "designed to be slim, compact and lightweight."

    The case is available in black, blue, green and pink and will cost you $119.99 (or $20 if you get it for a standard iPhone 6).
