New macbook Pro M1 chip waking when asleep with log "SMC.OutboxNotEmpty" wake reason

My new Macbook Pro with the M1 chip, when sleeping and on battery, will slowly drain. I looked at the logs and the wake reason is:

"Wake reason = wlan, kern.wakereason: 'SMC.OutboxNotEmpty smc.70070000 wifibt wlan"

This happens every few minutes or so in the log.

I checked the system preferences and Wake for Network access is OFF.

Never had this issue with prior MacBooks, until the new M1.

Any ideas?

MacBook Pro 13″, macOS 11.0

The com.apple.PowerUIAgent process is associated with the optimized battery charging option. To disable this maintenance process, just need to uncheck the optimized battery charging option. Anyway, it's my pleasure to solve your problem.
