Hello!

I have acpi enabled kernel already. 

According to Juan "There was a bug in the idle loop that caused extra work
in the background, this was fixed ~1 week ago." So, i will upgrade to
4.99.32 today and lets see the difference.


Following configuration (thanks Dianne) let me have 1 hour 50 mins battery
life: "sysctl -w machdep.est.frequency.target=800 " and i also reduced
screen brightness.


Regards,
