how can you tell a macbook is charging when it's switched off?

I charge over USB-C, so there's no little light on the cable. When the laptop is shut down there's no sign it's charging at all. Is there a way to check?

if the light goes green at around 80% and it seems to stay there, that's optimized battery charging, not a fault. it learns when you usually unplug and finishes the last bit closer to then.

On a MagSafe one the light on the plug tells you: amber is charging, green is full. With a plain USB-C cable there's no light at all, so the only way is to check the battery percentage when you turn it on.
