It’s way easier to slide XS in and out of the case than it was when I had the 6S Smart Battery Case. It works just as I remember and now I’m not concerned with returning to my desk to plug my XS in and solely relying on my S4 cellular connection to stay In touch at work late in the afternoon when I have to run around my building. Also, Way better than carrying my Anker powerbank around. Now my power bank stays in my backpack and when my Smart Battery Case runs out of juice it’ll recharge in my backpack when I’m out and about or I’ll use my USB-C charger to fast charge it.
