Seconding some other users: the battery life on the XR is phenomenal. I upgraded from an iPhone 6, which even with the $29 battery replacement couldn't last till the afternoon with heavy use. Now, with the XR, I've stopped feeling the need to carry a backup battery with me, and I rarely even use my charger at work.

It's quite possibly the only product Apple makes today that Steve Jobs might approve of. Maybe that, and the AirPods.
