I just upgraded my MacBook Pro to MacOS Big Sur Version 11.0 Beta, and my battery, even though the power adapted is connected, is showing the message "Battery is not charging", while displaying this (new) icon:

My Mac is indeed not charging, even though the battery source is the power adapter. How is it possible to solve this issue?


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.

  • The battery charging code is one of the things that was heavily overhauled, so it's not surprising to see bugs there, I would say. That's what Beta testing is for, after all. – Jörg W Mittag Sep 23 '20 at 19:52
  • I am now getting a notification in settings: "The battery's capacity is significantly reduced. To restore capacity, please check your service options." and I'm getting a "Service Options" button too. I wish if I would have not updated the OS to keep my battery alive – Adil Nov 16 '20 at 13:48

    Is it available in older mac? I have MBP15 mid 2015 and I can't see this option on Big Sur. – pawisoon Dec 9 '20 at 21:33
  • Yeah, that was the first thing I tried. Doesn't work. – SMBiggs Feb 17 at 19:35

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 :-)

  • +1 The 65W (90W in our case) worked great, thank you for saving us from an expensive service call. – tremoloqui Jan 22 at 4:16

Theres also a button when you click the icon to "charge to full now." However, its recommended to keep optimized battery charging on so your Mac battery can be prevented from aging quickly. to SMBiggs that button comes when your Mac will say "charge complete by [time] or charging on hold (rarely used on battery) I cant make that button come on demand, it is in the menu bar after clicking on battery icon

  • Where is that button? A picture is worth a thousand words. – SMBiggs Feb 17 at 19:41

Resetting and trying a different charger worked for me. How bad from Apple to drop such a bad feature on old MacBooks.
