I keep a USB C and a Lightning cable plugged into my 14" M1 Macbook so I can charge my phone and iPad. Is this bad for the machine/battery? My Macbook is usually always plugged in.

Thanks.

I was wondering the same, but also about keeping my MacBook Pro plugged in most of the time. What reason is yours plugged in most of the time, I am home at my desk mostly so have been doing this, is there anything definite on of this is ok for the battery?
 
Whenever I travel I pretty much use my mac as charger for my phone/ipad etc.

It won't be drawing from battery at any times where the power supply in has enough wattage to cover needs.

Leaving plugged in all the time isn't greatest, but that's why macos on 2018+ devices now keeps battery at 80% if it recognises usage pattern of always being plugged in to help preserve battery.

Do you have “optimized charging” enabled? It is supposed to monitor your charging levels and eventually keep your Mac charged to about 80% most of the time. Some of us use the 3rd party app Al Dente for that purpose as it lets you set the 80% charge rate and not depend on a learning algorithm.
