40% Battery Drain in 21 Hours While Sleeping on M2 Pro 16" MBP

[ryansebiz]

Hello friends - I'm having battery drain problems with my M2 Pro 16" MBP (Ventura 13.4). Nothing connected to the Thunderbolt, SD card, or HDMI ports. “Wake for Network Access” is disabled.

• Wednesday, June 14 at 3pm - unplugged at 80% and closed the lid, didn't use it again until Friday at 12pm
• Thursday, June 15 at 12pm - opened the lid and the battery was at 40%

System Settings > Battery > Last 24 Hours ("Battery Level" drops from 80% to 40% with no "Screen On Usage")

System Settings > Battery > Last 10 Days (same 40% "Energy Usage" yet no "Screen On Usage")

"Wake for network access" is disabled

Activity Monitor > CPU (sorted by Idle Wake Ups)

Activity Monitor > Energy (sorted by 12 hr Power, very high Messages "12 hr Power", I only received around 10 Messages)

Any ideas? Thank you.

This has been a recurring issue since the introduction of Apple silicon. It also happens on my M1 machine.

We don't have a definitive solution. My suggestion is asking Apple for help or try the workarounds discussed in the community.

Try grabbing a copy of Sleep Aid (https://ohanaware.com/sleepaid/) and see if the machine is constantly waking up and going to sleep again while it's allegedly sleeping. If it is, Sleep Aid may be able to shed some light on why it's doing that.

Not sure if this applies to you - but I had Microsoft Auto updater running at startup (which I didn't realise and disabled), and it made a MASSIVE difference to my battery consumption and decline
