Despite the size of your iPhone 7 Plus’ battery, you may find it’s not lasting through the day, especially if you’re a power user. Carrying around an external battery pack can be cumbersome, so why not streamline the process and grab a battery case instead. It’ll probably bulk things up a bit, but better bulky than a brick.

Most powerful

VOOE battery case

Staff Favorite

This case has a whopping 8500mAh battery, which more than doubles your battery life. Four LED indicator lights keep you apprised of its charge level. VOOE’s case also doesn’t have a ton of additional bulk, is easy to install, and comes in red, pink, and black color options.

Apple’s favorite

Mophie Juice Pack Wireless

Mophie’s Juice Pack comes in five colors and has a 2420mAh battery, which should give you an extra half-day’s worth of charge. This one’s ideal if you’re a power user but don’t mind charging up nightly. It has LED indicators on the back and proper cutouts for speakers and your camera. This one’s bulky, but it does provide solid protection, albeit expensively.

Which should you buy?

All of these battery cases will be compatible with both the iPhone 7 Plus and the iPhone 8 Plus. For my money, the VOOE battery case is the best option, since it has the most battery power. It should keep your iPhone going at least all day and into the next, and it’s protective without being extremely bulky.

If you’re wary of buying an unknown brand, the Mophie Juice Pack carries a well known name, so it’s a brand you can trust. Plus it comes in a variety of fun colors and is guaranteed to keep your iPhone’s battery secure and running around the clock.
