Adaptive Charging is a machine learning-powered feature used on Pixel phones, which learns your charging habits and charges the phone at different rates depending on your usage. If you plug it in overnight, the phone will eventually charge slowly at these times, while if you tend to top it up at regular intervals, the battery will charge quickly.

Well, Google may be bringing adaptive charging to the Pixel Watch line-up, which could be invaluable in preventing battery degradation over time. This feature is already readily available on Pixel phones and the Pixel tablet, and a deep dive by Android Authority suggests that the Pixel Watch could be next in line.
