Sleep mode on MacBook Air A1932 causing battery health to drain

Since you’ve already replaced the battery and saw the same issue return within a week, that tells us the battery itself isn’t the root cause. On this particular model, unexpected drain while the laptop is asleep usually means the system isn’t actually entering deep sleep, even though the lid is closed. This can be triggered by software processes that keep waking the machine, corrupted power-management settings, or a hardware subsystem—such as the charging circuit or battery-management controller—not handing off correctly to low-power mode. These issues won’t show up in the standard battery-health report, which is why everything appears “normal.”

To move forward, I’d suggest a few checks. First, verifying sleep behavior can reveal whether something is waking the system repeatedly. Resetting the system management controller and NVRAM is also worthwhile, as it can correct power-state issues that develop over time. Testing overnight in Safe Mode is helpful too—if the drain disappears there, we know the cause is software-related. It’s also a good idea to disable features like Power Nap and Wake for network access temporarily and review Activity Monitor for any apps that continue running in the background.

If the problem persists even after all of this, the most likely cause is a fault on the logic board, such as a power-rail leak or T2 standby issue.

Shut down the MacBook when you won't be using it for more than a day.
