Customers are saying

Customers are satisfied with the iPhone 11 Pro Max Smart Battery Case's extended battery life and wireless charging capabilities. Many appreciate the improved grip and protection it offers, along with its ease of use and sleek design. However, some find the case to be bulky and heavy, and a few have noted concerns about its durability. The relatively high price point is also a recurring criticism.

    Sturdy and not too heavy. Keeps my phone charged. Doesn’t overheat like Mophie cases do. It’s worth it plus I got it on sale so even better!

    Great quality and depend on the day the case extends the battery life anywhere from 9.5 hours to 11.5 before the phone battery is used.
