My M1 Max MacBook Pro's Battery Drain Mystery: Solved by Sleep Aid
2025-08-01
My M1 Max MacBook Pro started mysteriously draining its battery overnight. Analyzing power management logs with `pmset` proved too complex, so I wrote a small analysis tool, but it wasn't very helpful. I then discovered Sleep Aid, a tool that displays wake events more clearly and lets you change settings. It turned out the 'Wake for maintenance' option was disabled; enabling it fixed the issue, and my battery now lasts through the night.
