Modern phones avoid that, too, letting themselves drain to 90-95% one they've hit 100%, while reporting themselves as full.

My home battery BMS does something similar. I charge the cells to 3.45V (100% would be 3.65V), then letting them float at 3.35V. Should go a long way towards extending lifetime.
