Macbook Air 2018 battery issues

[john7979]

Hi all,

I got a Macbook Air 2018 about 1.5 years ago, brand new. In the beginning it worked fine. But since about three weeks it has battery problems: at seemingly random battery levels (percentages) it shuts down without any warning. Just a black screen. I have to plug in the power cord in order to be able to boot it up again.

This happens at battery percentages like 40%, 60% and 70%. I updated to iOS Catalina last week, but the problem remains.

Yesterday it even started to happen when the power cord is connected...

Do you have any ideas what could be the cause and what to to? It's rather frustrating

Update: yesterday my Mac turned off instantly after powering it on. At home, when plugging in the battery, it

I have similar problems which is why I have just joined today. My Mac Air required charging a few days ago so I plugged in the charger, not it's just completely dead. I bought a new cable and still no luck?
