Hello, I've been dealing with an issue for the past 3 weeks that I am unable to solve. I have an 2017 m7 1.4GHz, 16 GB RAM Macbook since last September. Up until around 3 weeks ago, it worked flawlessly.
Now, when I close the lid for the night (say with 80% battery), and I wake it in the morning, there will be 30-40% battery remaining. Power Nap is disabled. Inspecting the Power Management logs shows that the system went into sleep due to 'Clamshell sleep', and there are no more events until "Wake from Deep Idle due to ... Lid Open". Therefore, the machine enters sleep and remains in sleep until it is woken. So, why the battery drain.
One might suspect that a hardware issue is causing it to drain; however, if I reset the Energy Control Settings to their defaults, shut down the machine, reset the SMC, reboot and then repeat the overnight experiment, there is only 1-2% drain overnight (totally normal). About 1-2 days later, it is back to the above scenario: draining the battery while asleep. I have also disabled SIP, removed the sleepimage, then reenabled SIP to make sure that the sleepimage is not corrupted.
Based on other threads in this forum, I have the Power Management settings:
% pmset -g
standbydelay 10800
standby 1
womp 1
halfdim 1
hibernatefile /var/vm/sleepimage
powernap 1
gpuswitch 2
networkoversleep 0
disksleep 10
sleep 1 (sleep prevented by sharingd)
autopoweroffdelay 28800
hibernatemode 3
autopoweroff 1
ttyskeepawake 1
displaysleep 10
tcpkeepalive 1
acwake 0
lidwake 1
Any suggestions are greatly appreciated.
Cheers
