Remember when cell phone batteries would last for a week, and recharging wasn’t a nightly task? Our devices are now capable of so much more than just telephone calls — in your pocket, you have the entirety of the internet, a myriad of sensors, and tons of other capabilities. So is it any wonder that average battery life is now a day, maybe a day-and-a-half at most?

What do you do when you need to use your iPhone 8, but you’re worried about the battery life (you can read more about what we think in our iPhone 8 review)? Well, a power bank is a good idea. But they’re often bulky, inconvenient, and difficult to use on the move. Battery cases may be a better solution to your issue — attached to your phone already, they don’t need extra cables, or extra space. They just clip onto your phone, and they’re there for when you need the extra juice. That’s why we’ve put together a list of the best iPhone 8 battery cases that we’ve found on the market today.

Since the iPhone 8 is almost the same size as the iPhone 7, most of the battery cases that we recommended in our iPhone 7 battery case round-up will work just as well.
