Thanks! I'm hoping they will fit as I have several X cases already. I kind of thought the X Performance would be a little thicker but not by much. I'll know cone Wednesday or Thursday when mine arrives. I went ahead and ordered a few X Performance cases for it yesterday just to be safe. Still though it would be nice if what I have already fits it. I appreciate the information on that and letting me know. It's much appreciated.The dimensions are slightly different: https://www.phonearena.com/phones/compare/Sony-Xperia-X-Performance,Sony-Xperia-X/phones/9988,9986. Cases for the X, if they do fit, would be pretty snug on the Performance.
That's a good point. I didn't think about that. I've read so far that if I have the Sony Xperia X cases that if they fit the X Performance they will just fit a little more snug as I have this really good looking light brown folio case that I want to use on my X Performance whenever it gets here Thursday which by the way is taking forever!! I'm so ready to get it. I've ordered several other cases for it to be covered just in case my X cases didn't fit. I typically don't use cases really so I ordered this sleeve which I've heard is awesome. Here it is along with a full body protector and screen protector kit that is anti glare and of course anti fingerprint too. Here's a pic of both.A major concern is button placement. Trust me, you don't want the camera button getting pushed randomly while in pocket. Been There Done That on a different phone where even the official case caused an issue. Next thing you know the phone is hot and when you pull it out and examine it you have 547 pictures of the inside of your pocket.

Stick with cases that are made for the Performance, IMHO.
