M1 MacBook Battery Drain on Standby – Anyone Else?

Tags: Apple, Browser, Byod

Hey everyone,

I’ve been using an M1 MacBook Air (2021) for about two years now, and overall it’s been great. However, lately I’ve noticed something odd: the battery seems to drain quite a bit while in sleep/standby mode. I used to be able to close the lid and come back two days later with barely any change in battery percentage. Now it drops by 15–20% overnight.

I’ve tried the usual stuff:

Disabled Power Nap

Turned off Bluetooth before closing the lid

Closed all apps before sleep

Reset SMC and NVRAM

I’m on macOS Sonoma 14.5 (latest update as of this post). Has anyone else experienced this? Any known fixes or logs I should check to diagnose?

Appreciate any insights or even just to know I’m not the only one!

Thanks,
— James

Do you leave it plugged in when you are near a power source and using the MacBook? Many portable batteries start degrading seriously after 2-3 years. Might be time to get a replacement battery. This is not unusual and is similar with many cell phones. I use a Samsung Tab 10 Ultra that is about 1 year old and do notice that the battery drains faster than when I first got it. Nothing unusual to see here folks.

The idea about WiFi is spot on.

I had a MacBook Air in 2011, I think, and I shut off Bluetooth and Wifi when not in active use which made a major impact on my battery life/charge. I haven’t had that computer for almost 10 years now.
