If you're still using the iPhone 7 or iPhone 8, particularly if it is one you bought at launch or a couple of years back, then you may have noticed your phone's battery getting less effective over time. Even if you're using a new version, you know that's going to happen eventually. As it is with all phones. Thankfully, you can grab Apple's official Smart Battery Case on sale for just $59 at Amazon. It has never dropped this low before and, at that price, it is around $25 off its average. The discount applies to the black, red, and white models.

iPhone 7 Smart Battery Case

If you're using an iPhone 7 or iPhone 8 from a few years back, then you may have noticed your phone's battery getting less effective over time. The Smart Battery Case helps ensure that your phone lasts longer without you having to think about it.

$59.00 $83.83 $25 off

The Smart Battery case helps ensure that your phone is never dead by providing additional power to it without you even having to turn it on. Combined with the Smart Battery Case, your iPhone 7 will give you up to 22 hours of battery life for browsing the web, up to 24 hours of watching video, and 26 hours of talk time. The case is actually compatible with the iPhone 7 and iPhone 8 however you will not be able to use the wireless charging function of the newer handset with the case on (which you won't need as much with this case, of course).

If you have a phone that's more recent like something from the iPhone X or 11 lineup, then grab the appropriate version of this battery case instead.
