Quality
Saved at a sensible quality
Photos straight from a phone are saved at quality 90 to 95. Quality 72 to 85 looks the same on a screen, and the file is usually half the size or less.

How the JPEG gets smaller
Phones and cameras save JPEGs with far more data than a screen shows. Two things come out.
Hidden data
Camera details removed
The camera model, date and GPS location are stripped. That saves space and keeps where the photo was taken private.
