    Battery case arrived on time. The battery case is a little heavy, but I am used to it as I use this case every day. I can go almost 2 days without charging my phone. Great purchase if you need extra power during travel. I definitely recommend

    Too Pricey

    For what it is... it’s just too expensive and adds a lot of weight to an already heavy phone. This case is great for vacation or long trips, but not for everyday use.

    Works as advertised. Mainly bought this to take on vacation trips where I will need the extra battery. I don’t use for everyday because it is a bit heavy and uncomfortable to use for everyday. My battery lasts all day with this!!

    I bought this accessory wanting a battery case for my upcoming trip. I've had Mophie cases before but this is much better. It uses the battery case's battery before your phone's so it won't wear down your battery. This case works perfectly!

    After a year my iPhone XS Max barely makes it until 11am in a work day with a 06am start. I’m constantly using it for estimates, navigation, calls to clients, other management, and my wife not to mention 15-25 emails a day. This allows me to leave for work at 5 and not have to worry about it dying ALL DAY!!! My screen time is 9 hours a day and this case supports it. I’m very cautious about how and when I charge my phone and keep it cool on hot days so the battery life issue wasn’t due to an abused or neglected battery. Thankful to apple for the rad case! It’s not like the otter box I had but, I’d still attractive

    Wonderfull extended battery case. keeps up to 2 days with a full charge along with the phone fully charged. just a little heavy but definitely feels like the phone case itself when put on than an extra piece of equipment.

    I really like the feel of the silicone. It fits really nicely in my hand. It can get dirty easily, but it wipes clean for the most part. It charges using the case first and then my phone charger kicks in. It’s super easy to use. I really like it.

    I love this case and use it daily. My phone is well protected if it is dropped and I’m not plugged into a cord all day because of fear of having no battery. I’m fully charged all day long and I’m talking 18-20 hour days.

    Very easy to use, clean fast plug and play- good for long trips as I catch planes 2 to 3 times a week. Cut the extra battery for good! The application that governs power toggles intelligently always charging phone first! Worth every dollar!

    Expensive but works

    I ended up trying several other battery cases before committing to this one because it is expensive. It works very well with the iPhone XS Max and supports all accessories at the lightning port that I threw at it. The other ones didn’t support the full functionality of some of the accessories at the lightning port. So this something to keep in mind if it is important to you. As others have mentioned, the only negative is that there is no power switch so you can decide when you want it to charge your iPhone.

    Loved it. I no longer had the phone but it saved me so many times over for not having enough juice during the day. The bump on the back isn't too bothering though it adds a little weight.

    I have the latest Apple phone and have had for about 7 months and now the battery seems to be being used faster and faster. Maybe I’m on it more and more? LOL. Anyway I can be on the phone pretty much all day and by the end of the day I may have 30% left on my phone and then I put on charger overnight and can start all over again the next day. I ready the reviews and how some people do t like that it uses up the case battery before the phone battery but really who cares! Very expensive but decided to treat myself. If there is one negative it is that the phone is very slippery and I’m worried I may drop it.

    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

    Purchased this while it was on sale and I love it. You can wireless charge the unit without the phone inside, this is the second unit that I have and I use them every day to keep my phone charged.

    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?

    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).

    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!
