I was wondering if I just left my Mac on the charger all day if it would take power from the charger instead of the battery because I want my battery capacity to last me as long as possible.
MacBook Pro 13″, OS X 10.11
Your high quality MacBook Pro does not behave like a $10 toy and charge its battery to oblivion if left alone.
Your MacBook Pro uses ‘smart charging’ to charge in the optimum way, and only when necessary.
Your computer performs best when connected to AC power.
In general, you should ALWAYS connect AC power when it is possible to do so, and only run on batteries (which could be somewhat slower) when no AC sources are at hand. Your Mac will NEVER over-charge.
Catalina software 10.15.5 and later for MacBook Pro with T2 chip (2018 models and later) and all Apple-silicon Macs include a new feature called Battery Health Management. Now, based on your usage patterns, this widens the hysteresis to initiate a charge cycle at a lower level, and stop well before 99 percent.

That computer is a battery-CAPABLE device. It is not optimized as a battery-operated device. (It is NOT an iPhone.)
Your computer performs best when connected to AC power. It can use the full output of the Power Adapter AND when doing especially challenging work will also freely "borrow" power from the battery. In some cases, even with the power adapter connected, the charged state may decline during stressful work.
When used only on battery, your computer has no extra cushion of power, and may perform more slowly. However, for ordinary non-stressful tasks this may not be objectionable (possibly not even noticeable.)

Ok thank you I was just wondering it because I just got this MacBook and I never owned one before but my windows one when I left it on the charger for months while occasionally running some heavy emulators in the background it ruined my battery health. but thank you for responding quick!
so if I leave my computer plugged in it would take power from the cable and not use the battery what so ever?
If I just leave my M3 Pro MacBook Pro in the charger would it make my battery capacity lower
