No one has come up with a good theory so far. There’s a small chance there’s a change in the battery charging circuits, but it could just as easily be a simple segmentation decision. I think you’re right that it’s purely a life preserving thing. Filling up a battery to 80% is better for it than 100%. So if people are willing to make that choice they may be able to use the battery a little longer as they’re not stressing it as much.
