Best Battery Cases for iPhone 7 Plus iMore 2021
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.

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 so much battery power. It should keep your iPhone going at least all day and into the next, and it's protective without being extremely bulky.
