I have a 2018 MacBook Pro 13 inch (the one without the touchbar). Over the past weeks, I have twice faced the situation where the charger is plugged in but the battery is draning and I get a "Battery not charging" message if I look at the Activity Monitor or hover over the battery icon.
Resetting the SMC seems to fix the problem but it reappears after a few days. Should I continue resetting the SMC each time or try something else? The laptop has a third party warranty but I cannot leave my home due to the COVID lockdown.
