This is false. It's true that staying at 100% is harder on lithium ion batteries than staying at 40%. However, the wear due to charge cycles is way, way more significant. Your battery will see much less wear if you keep it at 100% for some time vs discharging and recharging it a few times between (e.g.) 40% and 80% during that same time.
