Battery Drain Issue on Macbook Air M1 During Sleep Mode Below 30%

I've been enjoying my Macbook Air M1(base model) for about a year and a half, and overall, it's been a fantastic experience. Recently, however, I've noticed a peculiar issue with the battery. Specifically, when the battery level drops below 30% and the laptop is in sleep mode, I've notice on several occasions an unexpected 7% battery drain. This has occurred on multiple occasions and is a new development. Despite regular use (about 5-6 hours per day), the battery generally holds up well for its age. I've checked for background processes, disconnected peripherals during sleep, ensured the system is up-to-date, and adjusted energy saver settings. I'm reaching out to the community for any insights or advice on this matter. If anyone has encountered a similar issue or has suggestions, I'd greatly appreciate your input.

Hello roh_96,


If you haven't yet, be sure to try running the Apple Diagnostics test. This can help to check for various hardware-related issues to see if anything comes up there.


If needed, this page will help provide details on the test, including how to start it: Use Apple Diagnostics to test your Mac - Apple Support


Prepare your Mac
1. If you're able to install the latest macOS updates, do so before continuing.
2. Shut down your Mac.
3. Disconnect all external devices except keyboard, mouse, display, Ethernet connection (if applicable), and connection to AC power. 
4. Make sure that your Mac is on a hard, flat, stable surface with good ventilation.



Start Apple Diagnostics
Apple silicon
1. Press and hold the power button on your Mac. (Every Mac has a power button. On laptop computers that have Touch ID, press and hold Touch ID.)
2. As you continue to hold the power button, your Mac turns on and loads startup options. When you see Options, release the power button.
3. Press and hold Command (⌘)-D on your keyboard.


Cheers.
