MacBook Air M1 battery drain when sleeping
Check the activity monitor under &quot;Battery&quot; for usage statistics.
Sort by &quot;Energy Impact&quot; &amp; &quot;12Hr Power&quot; tabs to find the app that is using the most energy. If it's an app that you are not running on the foreground, then close those applications.
Also check if any apps are Preventing Sleep by sorting &quot;Preventing Sleep&quot; Tab.
