Macbook M1 battery drain fast after update to 15.3.2
My mac battery would run from 100% to 0% overnight after the update. Basically the battery keeps running even when it is not in use. This issue never happen before the update. And my battery health is 84% which is normal. I checked the activity monitor and the figures look ok.
I don't know if update to 15.7.2 can fix the issue or could make it worse.
MacBook Air 13″, macOS 15.3
Update to the latest available Sequoia OS, 15.7.2.
There have been many, 8 or 9, releases to address security, bugs and glitches and make improvements to the OS performance between 15.3.2 and 15.7.2. It may well be there is a battery management adjustment in there somewhere.
