Apple - "Battery is not charging" after updating to MacOS Big Sur

UPDATE: This looks like a new feature of MacOS Big Sur. In the Battery settings, there is a new option called "Optimised battery charging" which stops battery charging after 80% to reducing battery ageing. By unchecking this option the battery starts charging again normally.

Resetting SMC helped me with "Charger not recognized" after update to Big Sur.

I am using Macbook Air 2020 with 30W charger. Interesting was that after update I was not able to charge with 30W original Apple charger but it was charging from 65W AVACOM USB-C power bank.

After reset (option+control+righshift etc) it started recognizing the original 30W charger - https://support.apple.com/en-ca/HT201295

I hope this helps you all too.

Happy Big Surring & charging :-)
