MacBook Air 2022 M2 Battery drains with strange battery level record
Hi, everyone! My battery drains about 25% over night after completely shutting down. I bought this MacBook air 2022 M2 only three months ago. What is more strange is that the battery level record indicates that it is on charging over the whole night, see the green bars below in the range from 12A to 9. I didn't charge it. How to explain this? Can anyone give any suggestions to find the problem? Thanks in advance.
By the way, to solve the battery drainage problem I erased my mac and installed the brand new Ventura system today, so I have no third-party apps installed on this Mac. Days ago, I went to see the Genius Bar technicians and they found no problem after diagnosing the whole Mac. But, there must be a reason, right?
MacBook Air, macOS 12.6
