Studio Display Charge MacBook Pro

[performa_6400]

This was kinda asked before, but not fully answered here.

Is it harmful to only have the Studio Display charge a MacBook Pro (16" M1)? The MagSafe will only charge the MBP to 80% unless told to charge to 100%. The Studio Display seems to constantly charge to 100%.

If you have Optimized Battery Charging turned on, charging will stop at 80% or so when hooked up to the Studio Display.

About Optimized Battery Charging and Charge Limit on Mac - Apple Support

To improve the lifespan of your battery, Optimized Battery Charging allows your Mac to learn from your daily charging routine so that it can delay completing a full charge in certain situations. And with Charge Limit, you can limit what your Mac considers a full charge.

Sometimes it takes a bit for the MacBook to learn your charging routine. In my case, it took a few weeks.

I agree with the past above - the Mac will eventually learn not to charge to 100%. I have a 14" MacBook Pro in clamshell mode with a Studio Display 24x7 and you see below the system eventually learned this (but it took like 2.5 weeks).

I didn't know this was now built-in to macOS. I've been using Al Dente to halt charging at 75% until I need more.

I found the optimized charging feature to be inconsistent at best and still use Al Dente.
