-Nearly all apps adding black bar to top and bottom which severely reduces screen size.
-Videos sized to full screen chop off the bottom, or if you don’t expand to full screen the video feels very small.
-FaceID didn’t work when phone was positioned on center console of car.
-FaceID takes 1+ sec to unlock compared to instant Touch sensor.
-No headphone jack unlike 6s Plus.
-No noticeable speed increase in web browsing and normal (non-gaming) activities compared to 6s Plus.
-If you lock phone using right side button, you need to click right side button again (?!) and then use FaceID to unlock.
-Weird (bad) glare in sunlight when wearing polarized sunglasses.
-Screen resolution and quality didn’t seem that much different/better then my 6s Plus except when looking at Photos.
-Corners of X chop off precious real estate from phone.
-Annoying to have to position fingers/hand at top left and right of phone to swipe to access menus.
-2716mAh battery of X compared to 2750mAh of 6s Plus.
-174gram weight of X compared to 188 grams for 6s Plus, so practically the same weight but much smaller screen.
Only positive was the camera did take nice pics.
