M1 Macbook Pro battery drains very quickly while asleep
My new M1 Macbook Pro 14" had really great battery life when I got it — I could go like 5 days using it several hours a day without charging. But for the last month or so, it drains very quickly while it's asleep. If I leave it unplugged overnight it will be dead by the time I wake up. This is what System Prefs shows, draining while the screen is not on at all:
If I enter pmset -g log | grep -i "wake from" in terminal, it looks like it's darkwaking every 10 seconds, which doesn't seem right:

This was happening at least since 13.3. I've also turned off Power Nap, turned off wake on LAN, turned off all sharing, and done an OS reinstall. Nothing has fixed this.
