Received my 14" M3 Pro on November 18 and have been using it plugged in all the time. However, I shut down every night and boot back up in the morning because I have to store the laptop somewhere else (for now) when not in use. Optimized Battery Charging kicked in on week 2 of using it and it started limiting the charge to 80%. However, since I would shut down the laptop and disconnect the charger every night, sometimes in the morning it would charge back up to 100%, realize it is still being used plugged in, then come back down to 80%. Basically, all my charge cycles were going from 100% to 80% to 100%. As a result, my battery has increase its charge cycles by 1 over the past 3 weeks of usage. Laptop came with 2 cycles on the battery and 100% health. Now it is 3 cycles with 100% health after 3 weeks of use.

I just want to know if this is okay till I can finally keep the laptop in one place, plugged in all the time, and powered on all the time which would probably result in limiting the charge 24/7?

Here is what happened today: I shut down on Thursday night with the battery charge limited to 80%. Powered on today (Saturday) with it plugged in. Started charging to 100% then back down to 80%.

Going from 2 cycles to 3 is nothing. It’s to be expected. If you are worried about it going to 100% for awhile, then you might consider something like al dente. It looks like the battery optimizer is doing its job but it is my personal opinion that “al dente” does a better job. I think al dente has a free version you can try.

Thanks.

My concern was not increasing charge cycles but increasing charge cycles for no apparent reason (like going from 80% to 100% and then back down to 80%) while being plugged in all the time. Guess I'll wait and see how it is when I can leave the MacBook on and plugged in 24/7 (meaning without having to shut down everyday).
