Customers are saying

Customers are delighted by the iPhone XS Max Smart Battery Case's extended battery life and wireless charging capabilities. Many appreciate its protective qualities and the overall build quality, noting a positive user experience and ease of use. However, some users find the case to be somewhat bulky and heavy, and the price point is a common concern. The size increase is also mentioned as a factor affecting the user experience.

    It worked well to keep my phone charged all day but the quality of it wears down and chips very fast. Another overpriced item by Apple that was probably made in China.

    The case so t last long and it’s a waste of money. The rubber part literally starts fading and comes off after a week. Literally had to be the most overall priced case of the 2020z
