Yes and No. Yes if you keep plugged in battery count cycle will be very low, but for protecting the battery then no. It will still deteriorate over time and even with low cycle the battery will still need replacement.

Imo just use as how you like , my battery died recently after about 6 years and 90% of time i use it plugged in, 10% on
Battery itself. It died on the 205 cycle shown on coconut batt.
So if you asked me i am satisfied the battery can last me that many years lol.
