    I have always loved mophie cases. I own a car charger that is magnetic and it helps with my long distance drives. The downside of this new version of the case for the Samsung galaxy s9+ is it only holds 1 single partial charge for my phone. Where as my old one for the s7 edge could charge my phone up to 3 times on a normal day. So I am disappointed with the manufacturer of my mophie case for a smaller internal battery.

    Have owned one of these for the last 3 Samsung Galaxy phones I've owned. They are great if you watch movies or stream to have power "to spare". This model returns to the better way of attaching to the phone the model for the Galaxy S7 had a front bezel piece that was hard to remove and flimsy.

    I love having the charging the capability without having to carry a separate device. That being said, they have got to find a way to do it without adding so much weight. It is almost too heavy to hold. Also, I have had one before and it used to fully charge my phone. Now it only gets to about 70%.

    I have other Mophie chargers. This is my 1st actual Mophie charging case. Huge fan of Mophie. But this case is def not good for any added protection. Though it is very nice, it makes my S9+ too bulky and weighty. Adds way more weight to the phone than it should. Probably will be returning it.

    This Juice pack has allowed my daughter to meander out and about for hours longer now. The battery pack is Dads insurance policy, knowing that she will be able to call out when she forgets to charge her phone.

    I bought this for my son. We play Pokemon Go a lot. This case let him play a lot longer & easy to have. Protects the phone and gives him lots of enjoyment. I like it so much I just might buy one for my phone.

    Better quality than the last generation. It has small ports to the speakers which allow for better sound quality. The case slides off and on easily without any snapping parts. My only complaint is that it doesn't really add much more battery life. It seems to only charge my phone battery about 45%. For the added size and weight I would have hoped for more.

    I had a couple different mophie cases for my old iPhone and they both were great. Now that I have my Samsung Galaxy 9+, I decided to but a Mophie case for it. They never dissapoint.

    this case does was it is supposed to do. Charges the phone and keeps life longer. But it does not protect the phone from damage. Dropped it and phone broke had to buy another. It is a charger not a phone case. Know that going in and you should be fine.
