I'm asking about this one. I also have optimized charging enabled and since my MacBook is typically plugged in , it pauses charging at 80% . Why is yours showing a plug icon and mine shows a lightning icon? what am I missing here.
The issue no one is understanding here is that the battery charge level is never able to remain at exactly 80%. It will drain a bit and macOS will top it off again by charging it a bit again so it remains around the 80% level. And the battery information shown on the menu bar and elsewhere in macOS is not always 100% accurate or in real time....it can lag behind.
Plus, even with a Charging Limit or Optimized Charging enabled......macOS will will the battery to drain & charge beyond the 80% mark. Read the Apple documentation here:
About Optimized Battery Charging and Charge Limit on Mac - Apple Support
Besides as @Grant Bennet-Alder likes to say: 80% charge is a side effect, not the goal (although it may be more of the goal for Charging Limit, but Apple still says otherwise in their documentation).
People should not worry about their batteries. Just ignore the battery & its condition. Use the laptop until the battery no longer performs to your expectations. Then & only then look at the battery information & details to see if it mentions a problem. If it shows "Service Recommended", then you have your answer. Of course you can check the battery condition every day and sooner or later will see "Service Recommended" even though the battery is still performing to your expectations. Do you want to waste money on replacing the battery if you haven't noticed any problems with battery runtime? Or would you rather get the most from the battery before spending money to have it replaced?
If you enable Optimized Charging.....use the laptop & forget about it. If you decide to disable Optimized Charging....yes there are cases where this is best for how some people use their laptops. In the latter case with Optimized Charging disabled you should periodically run the laptop on battery at least once a week so it becomes habit, but chances are you are already running the laptop on battery if you disabled Optimized Charging. Again....use the laptop & forget about the battery other than a once a week drain & charge.
If you look at Apple's own documentation which I linked....even keeping the battery at 80% Charging Limit is bad for your battery. A batter needs to be exercised once in a while for optimal health.
