probably an app acting up, you might want to re-install the latest update with XC

@VNT

Could you test the phone without the SIM and SD cards? use WiFi for few hours.

Hello!

Have you solved this issue? If so, could you please clarify how you did that? My Xperia X Performance restarts by itself about 3 times per day.

Thanks,

Dmitry

Hi I have the same problem with my X performance.
I have tried the software repair 2 times.

It is still the same.
Apps are crashing, even the crash handler crash.
Chrome browser have problems on a lot of pages.
And the phone freezes and reboots.

Best regards.

I've send it to Sony RMA on Jan 9th, and got it back today, I have to test it out for a few more days.
