If you’ve updated an older iPhone to iOS 8, there’s a good chance that it’s hurting your battery life. But, luckily, you can do something about it by buying special iPhone cases that also pack built-in external batteries. Skiva Technologies makes such iPhone battery cases, and they’re on sale right now on Amazon at a huge 80% discount.

Regularly priced at $99.99 a pop, the Skiva PowerSkin battery cases each offer up to 2,000 mAh of extra battery juice, effectively more than doubling the battery life of the iPhone models they protect, including the iPhone 5, iPhone 5s and iPhone 5c, which all have batteries of up to 1,570 mAh.
Currently, these cases retail on Amazon for up to $27 (depending on chosen model), which already are great deals. But you can take off an additional 25% of that price by using this special coupon during checkout: GOWWM3DK. The price then drops to around $20 per case.
