> I suspect the high failure rate of drone batteries is due to the extreme loads drones put on batteries. Very few other devices are continuously operated at loads that will drain their batteries in a few minutes.
Indeed. The charge / discharge cycle causes physical strain on the carbon anode. Microscopic pieces of it break off with use, and are part of the cause of capacity degradation over time.
