    I get that it’s pricey, but you won’t find a better battery case for an iPhone than this one. I absolutely love the feel of it, along with the smart capabilities it has to work so seamlessly with the phone.

    Great quality and does a brilliant job of maintaining charge for a LONG time. My only negative mark is that it can’t be turned on and off when required which would be handy.

    Heavy, but I got a deal at $30 because it's an iPhone 11 and the 13 is out. I swap cases when I travel and enjoy the feel and weight so I know where it is. Hope it lasts a full year for the price. Maybe I can resell it??

    I had this battery case for my xs max, so it was no brainer for my iPhone 11. Once use get use to the bulky case, you won’t own iPhone without this case

    This is a great addition for the iPhone Max family from Apple. Very streamlined and does what is suppose to do, Give additional life (Charge) when you do not have access or time to charge when on the move.

    I really like this charger but it took some getting use to the bulkiness. The down side is that over time the finish of the case wears off which is cosmetic but it still gets the job done.

    Perfect companion when I am on the go and I need that extra battery life to get me through the day. I think apple made a great product when they introduced the smart battery case.

    Best case out there. I can get at least two days out of a single charge on my phone battery. Sleek and comfortable. This is my third case for different iPhones and they’re amazing.

    I like the battery storage but the case sucks, color has faded, and the rubber has chipped literally only thing I like is that the battery has held up well.

    I’ve had this case for a couple of months now, and I honestly love it. I get about a extra 10 hours of usage out of my phone with the case on and I couldn’t be happier.

    These last about a year but at the current prices it’s worth it. Plus after a year I want to replace my case anyway because of the damage I inflict on it.

    Nothing but awesome. My iPhone 11 Pro Max lasts me over 2 days. Perfect whenever I travel, since I tend to use google maps often, battery drains, but with this I have no worries!

    This is a game changer for the heavy user. Less charges and a piece of mind. Your charger will feel some what neglected. Lol.

    Bought it since the normal phone battery stopped lasting the whole day. Works as expected and usually lasts all day before the phone battery kicks in.

    While I loved this case it’s really unnecessary for those that live day to and don’t need the extra juice, it would have swayed me if it allowed reverse wireless charging sadly this something apple is saving for the next iteration of their devices.

    I waited for this case to become available and as soon as it was, I bought it. I’ve used Apple battery cases before and there really is no substitute. Get it - it’s worth the dough!
