For Apple’s iPhone 7/8, the Apple Smart Battery Case is definitely the best battery case there is. It’s elegant and convenient, but it also provides iPhone compatibility you won’t get from any other device. Of course, the problem is that it’s very costly. Many iPhone users are prepared to pay the Apple tax, and that certainly doesn’t mean anything wrong… but why pay more, then? Go right now to Amazon and you can get a $21 discount in black or white!
√ The Smart Battery Case for iPhone 7 gives you extra battery life with the look and protection of an Apple-designed case.
√ Combined with the Smart Battery Case, iPhone 7 provides up to 22 hours of battery life for browsing the web, up to 24 hours of watching HD video, and 26 hours of talk time.
√ The Smart Battery Case also works intelligently with your iPhone to charge simultaneously when you’re plugged in, so both case and iPhone will have more than enough battery life to get you through the day, and then some.
√ The soft elastomer hinge and one-piece design make it easy to put the case on and take it off. You can even connect it to any Lightning accessory, such as the Lightning Dock. And iOS 10 or later allows you to see the battery status of your iPhone 7, your Smart Battery Case, and even your Apple Watch, all in one place.
