Hi,
Ever since I updated to the latest macOS update (macOS Big Sur 11.4), my M1 Mac will occasionally won't charge at nights when I plug it in. It comes up saying the battery is not charging under the battery icon in the menu bar.
Is this possibly a software issue or do I need to get a new charging cable for my M1 Mac?
MacBook Air (2020 or later)
Startup in Safe mode. https://support.apple.com/en-gb/HT201262 Choose the appropriate method.
To leave Safe Mode, choose “Restart” at the bottom.

Safe mode prevents your Mac from loading certain software when it starts up, including login items, system extensions not required by macOS,
and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility.
And it deletes some system caches, including font caches and the kernel cache,
which will be created again automatically as needed.

If battery charging is paused or on hold on your Mac
There is an Algorithm coded into Big Sur to Pause the charging process at about 80% when on the charger. It is intended to lower the number of Full Battery Cycles and thereby extending the life of the battery before it will need replacement.
My Macbook Air M1 updated last week (Early June 2021) and ever since it won't charge if I plug it in. However, if I reboot with the power cord plugged in it seems to charge. The minute I unplug the cable and plug it back in, it never recognizes it.
Even if the battery gets down to below 10%, it just keeps draining with no charge unless I reboot.
I can only figure this is a software glitch that an update will fix soon. If not, I'll have to contact Apple support as this laptop is less than a month old at this point.
I'd be interested to know if a reboot works for OP and if it charges then.
When I first started to get this issue, I usually had to restart my Mac with the charger unplugged and then plug it back in after it has rebooted.
Now, restarting my Mac doesn't even fix the issue. I have to now wait a few hours (in the afternoon) to plug in the charger so my Mac can charge.
I just got a refurbished M1 Pro. I plugged it in to migrate files from my M1 mini but the OS was not 11.4. So, I updated and now it won’t charge. Uuughhh
