Extends battery life by almost double, (which ain’t saying much in pre-iPhone 11 models). Works with existing iPhone lighting cables and chargers. Works seamlessly with iOS. Must have for normal iPhone users

I love this case it keeps my phone charged all day and I use my phone constantly! I love that it’s one piece too and not a separate top and bottom, and it wirelessly charges both case and phone at the same time.

Bought this couple days ago and what a great investment so far only use about half my case battery all day and still have a full phone charge. Plus can charge wirelessly why did I wait so long?

Case keeps my phone at 100% throughout the entire day until I make it back home. Fits in my hand perfectly & protects the back of the phone from scratches of course. Highly recommend if you’re always on the go!

Adds Hours of life

Purchased for a trip but ultimately decided not to keep it. It was a great companion for long days (and flights) away from a power socket.
However, you will ultimately find this way too heavy and difficult to use with the added bulk and weight.
It it easy to use (you literally don't do anything but put it on) and your phone stays at 100% for hours.
Buy if battery life is the utmost importance (sacrificing usability and portability).

This case was defiantly worth the cost as it allows me not to worry about battery life as well as the overall protection for my device. An amazing product I will use for a long time

When I know I’m going to be out all day this battery case is ideal. A bit heavy and bulky but it’s great having the confidence that I can depend on having all my phone’s services all day long.

Excellent power case. You can work or play on your phone as much as you want with no worry about the battery. Had one of these with an earlier iPhone. Like the new design better than old.

This case has a great battery size and is comfortable to hold in the hand, when you first put it on you might need to charge it (Charges your phone first if not charged all the way then the case, but sometimes it charges your phone and the case simultaneously). It does not have a button. BUT Apple does manage this for you. They do this automatically so YOU don’t have to worry about it. And it is a great feature. +Has tight integration w/ software +Battery% is in the battery widget that should show up & can add it if not there w/ the widget edit button. Hope this review helps you decide & if you buy it Hope you enjoy it as much as me, And I highly recommend it. Enjoy! :^D

This is a top notch battery case. The grip and mold makes it easy to hold 1 or 2 handed. Provides great extended battery life. I literally have no complaints with it. Great product by Apple.

Good battery case. The bulk of it is annoying, but I knew that before I purchased. I love not having to turn it on and off to do its job.

The case is excellent! Offers a lot to power-users and the wireless charging makes it even better. If you've ever used an Apple silicone case before, it's exactly like that but heavier.

Works great and vastly extends time between charges. Just a little too expensive. I paid $130 but had some Reward Certs so decided to try. Otherwise would have been cost prohibitive.

Works well. Of course it makes the weight increase slightly, but I have never ran out of battery even overnight without a charger.

I saw so many bad reviews I was worried about it . I took a chance and I love it. I’ve had it for about a month now and my phones battery health is still 100% . Unlike other battery cases this case uses its battery first than switches to the phone battery . The case last around 10 hours before switching to phone. I just charge my phone at night when I sleep, never need another charge all day. Great Product so far.

Only complaint is the price. This case works well and does what it’s supposed to do.
Wirelessly charges too.

The appearance to this phone case is great. It isn't bulky or heavy. So handy for charging my phone with out cables or hand held battery packs.
