I see the charge drop from 79% then go to 80%, but I don't monitor it closely. I'm fairly confident Apple has engineers that understand this exact use-case, and account for it via the battery management software.Do you know does it still increase battery charge cycles while it is constantly plugged in and optimized charging function where it keeps battery at 80% is in use? I mean does it continuously use battery a little and then charge back to 80%?
