Used the iPhone XR for a few weeks and I have to say amazing battery life. Battery can last from 1-2 days on full charge and normal use but your use can be different from the normal use. Good screen except for some of the unsupported apps. Yes, the screen is 1792*828 6.1" 326ppi..
Good Display; Speakers are great; Battery life is very good (2942 mAh; Great Camera
Some apps don't support XR display; Notch can block out parts of video when watching
