Mophie recently started shipping their Juice Pack cases for the Samsung Galaxy S6, and I picked one up for an upcoming trip. I’ve used the Mophie Juice Pack for an older device I had — the HTC One M7 — and thought it did the job of providing extra battery for your device pretty well.

The Juice Pack itself is standard Mophie fare: black, unobtrusive, and packing lots of protection. Mophie rates this device a 3 out 4 on their “Level of Protection” scale for devices. It definitely feels sturdy and tough. It is a 3,330mAh battery that outputs to your device at only 1.0A. That is a lot less power going into the device than if it was plugged into the wall, especially if you’re using a Quick Charge 2.0 charger or Samsung’s Adaptive Fast Charging block. Either way, the case gets its job done, as it can charge your phone at least fully one time and still has some left over battery to charge it further if need be.

The phone fits quite well in the case and it is quite slim considering its 3,330 mAh capacity. It is extremely snug in the case and if you try to take out the S6, it will require a bit of force, as the phone is so tightly kept in the case. I don’t mind this, though, since it doesn’t leave “marks” on the back of the S6's glass back, like some other cases do — I’m looking at you Spigen.

The case is not as thick as you would think, and is in fact quite a bit thinner than the Mophie Juice Pack I have for the HTC One M7, which only has a 2700~mAh battery. Here’s a look at those two:

The M7 Juice Pack has a significantly bigger ‘bulge’ in the middle of the device and the S6 pack remains relatively flush throughout. The buttons on the side of the S6 work really well on the device itself, as they are easy-to-press and provide good feedback, unlike some other S6 battery cases — I’m looking at you, ZeroLemon.

But overall, the S6 Juice Pack is a great purchase. It’s $100, sure, but it gives you that extra battery that you probably sorely need from using the S6 when you are out and about. It doesn’t make the device insanely big, and it is a case that protects the device well.

Here are some more photos to show you a bit more of the case, especially compared to the S6's case from Spigen.
