Like the iPhone 6, the iPhone 6s can be a little slippery to the touch, as it's rather thin, with no sharp corners. These cases will keep both phones protected.

The case I've actually used most over the last few weeks is the enCharge, mainly because it allows the iPhone 6's headphone and Lightning ports to be exposed while the phone is in the case.

Worthwhile cases primarily protect your iPhone from scratches, scuffing, and dirt without sacrificing aesthetics or interfering with the phone's functionality. Cases can also add helpful features.
