If you aren't totally satisfied with your iPhone 6's battery life, this popular Anker battery case is down to $40 today. We've seen it get a little bit cheaper in the past with a promo code, but this is still a solid deal, especially compared to most of the competition.
The case comes with a built-in 2850mAh battery, which should give your iPhone a 100% recharge on the fly, with some extra juice to spare. I know there have been times when I'd gladly pay $40 for more battery life, so be sure to check this out before the price goes back up to $60. [ Anker iPhone 6 Battery Case, $40]
