Not really. Worst thing is running the cell dead or cooking it. Modern lithium cells are much less prone to damage at full capacity (because it’s not really full, your phone’s charge controller is using intelligent management for 4-5% of it) and it doesn’t really matter how often you cycle charging on/off either with modern anode configurations. You’re correct on the usage part though. Tools wear out. Just how it goes.
