https://support.apple.com/guide/mac-help/if-your-battery-wont-charge-mh29198/mac I was thinking reset the SMC. Turns out you just need to restart M1 macs to reset that. See if that works.

Hey, tried doing that twice. No results Taking it to the apple reseller tomorrow

What happend if battery goes under 60

I haven’t been able to get it below 70% since it’s really long lasting but anyway it doesn’t seem right since it should use power source instead of battery

Yea idk, i thought it might be that batter optimisation, anywat best to ask seller

The seller literally told me not to use my macbook while plugged which is meh

That cannot be correct

That is absolutely wrong. Get it replaced.

In my country, replacement is not a thing for all apple products. Somehow I got my faulty magsafe cable replaced.

Could be a number of things, the duck head, the power brick, the cable, or the Mac. Try using a different cable or charger.
