I'm not happy with my 5X any more. It's lagging a lot, even after rebooting. I do not have facebook or any other 3rd party messenger app installed. My battery life is also atrocious - I'm getting roughly 1 hour of screen on time with Android OS gobbling up most of the battery. This is with location set to battery saving mode, screen brightness on automatic, and wifi set to sleep. When I first got the device, i was getting 3 hours of screen time, but since the 6.0.1 update, the phone is laggy and awful. Oh, and it drops cellular data connection randomly (with a new SIM) and often shows no sim card - if I put it on airplane mode and turn that off right away, the sim is found and data is back. I wish I could return it.
