Frequent Questions

  • Will the base case work with a mophie charge force mount?
    Yes, the magnets in your base case will firmly attach it to mophie charge force mounts, so you can conveniently dock your phone while you’re driving or working. However, your phone will not wirelessly charge from the charge force vent mount or charge force desk mount.
    Does the base case case work with other magnetic systems?
    We do not recommend using the base case with 3rd-party magnetic systems. The magnets in the base case will firmly attach it to mophie hold force accessories and to mophie charge force mounts, but we cannot guarantee that they will adequately hold when used with a 3rd-party magnetic system.
    Will the base case work with my iPhone 6/iPhone 6 Plus?
    The base case was designed to work with the iPhone 7/iPhone 7 Plus. Although the iPhone 6/iPhone 6 Plus will fit in the base case, the base case camera cone does not align properly with the cameras in those older phones, which may impair your photos. Because of this, we do not recommend using the base case with the iPhone 6/iPhone 6 Plus.
    Do the hold force folio and hold force wallet work together?
    You bet! You can attach the hold force folio to the base case and then attach the hold force wallet on top of that, giving you even more flexibility!
  • Can I use the hold force powerstation plus mini battery and hold force wallet together?
    The hold force powerstation plus mini battery only has magnets on the side that attaches to the base case. You can’t attach other hold force accessories on top of it while it’s attached to the base case.
    Does the base case work on a phone with a screen shield?
    We’ve made sure that the base case will work with phones that have a ZAGG Invisible Shield screen protector installed. We cannot guarantee a proper fit with phones that have other brands of screen protectors.
    Will this product demagnetize my credit card?
    Absolutely not! It’s perfectly safe to carry your ID and credit cards in the hold force wallet and hold force folio without harming their magnetic information.

base case is rated 3.9 out of 5 by 11.
Rated 5 out of 5 by from Fits great! I love the protection this case provides and still allows me to charge my phone without having to remove it to fit the charger!
Date published: 2017-08-31
Rated 5 out of 5 by from Works as expected I bought this for my wifes iphone. Hope the protection is better than the old one.
Date published: 2017-08-30
Rated 5 out of 5 by from Great concept I purchased from mophie.com. Case has kept my phone safe. What I really like is how the battery attaches. No extra cable. I've purchased 2 cases
Date published: 2017-06-01
Rated 5 out of 5 by from Great case! I bought this because i want the charger case and i wanted to test before I spent the money. I really like the case. I think the magnets are a wonderful idea. The case didn't budge when my toddler dropped it!
Date published: 2017-04-18
Rated 5 out of 5 by from Love the colors Happy with my purchase. The clear edges of case don't get stainy with the denim dye color like I noticed on my last tech 21 clear case. But so far the mophie seems to be holding up and my case doesn't turn blue from being in my jeans pocket.
Date published: 2017-04-01
Rated 5 out of 5 by from Perfect Match I bought this case because it matched the Rose Gold of my phone. The fact that it was part of the magnetic package was just a nice extra. I am so pleased that the color of the case is a perfect match to the phone! The "bumper" part of the case is clear to let the phone color show through but it is such a good match that it almost looks like the case is clear and the whole phone is on display. Nice grip and slim profile keep the phone safe to use and does not add any bulk to it at all.

Rated 4 out of 5 by from Awesome *sarcasm* I got the magnetic case for iPhone 7 and I had fallen down the stairs with my phone in my back pocket. My phone bent but the case is still in perfect condition. Good to know that there's no protection up to my weight.
Date published: 2017-01-13
Rated 3 out of 5 by from Good but scratches very easily. The case works well but the plastic back scratches so easily. Right after opening it and putting it on my phone it scratched IMMEDIATELY. You cant even lay the case back down on a table without getting scratches. I've had it for about a week or so and it looks as if I've had it for months or as if I rubbed the back against concrete. Looks like i'll have to buy a new one every month or so
