Exploring the Embedded Controller

Thank you both for the further explanations.

The closest thing you can do is to use a lower-power USB PD adapter, but this does introduce the possibility of draining the battery while plugged in if the computer consumes too much power. I can say from my own experience that a 30 watt adapter is fine if you’re using the machine mostly at idle or low CPU, and a 45 watt adapter is fine if you’re maxing out a single CPU core.

If I understand batteries correctly a draining can only happen if the Voltage of your adapter is smaller than the Voltage of the battery.

I found the topic where the power adapter was introduced: The Power Adapter

It says its a PPS adapter, and if I understood correctly the output current can be programmed. Does this mean someone can program it in a way to be like a 30W adapter?

But more generally, taking advantage of the charge capacity (SOC percentage) limit and doing fewer charge-discharge cycles will have a much more profound impact on battery longevity than limiting the rate of charge.

Ok I agree that maybe in the end this will extend the battery life not very much. I just thought that when users discuss the battery, it might be worth to also look at further details around.
