Hi all

After used MacBook Air M4 over two months it finally learned to stop charging at 80% during plugin but I don't like how it worked.

At 100% battery plugin the megasafe cable light has changed from green to orange color. Although it still plugin but it using the the battery powered. Battery would drop from 100% to 80%. At 80% it start to powered by adapter and stayed there.

I have unplugin at 80% battery. When I plugin, it start charging from 80% to 100% again. After reached 100%, battery would drop again till 80%.

Is it how the optimized battery charging worked ? or because it used 35W charger ?

Thank
