I'm wondering what power setting you all use. I have power nap enabled but not sure why lots turn it off.
Got a tip for us?

I had power nap on but I found that it kept waking up then doing backup every one hour, which doesn’t make sense to me.

I have power nap off. If the machine is sleeping, I do not want it to wake up. I really have no interest in getting emails on a laptop that is in sleep mode.
Is put hard disks to sleep needed? Like does it help the computer in the long run. Especially with SSD.

I'm wondering where the sleep setting went. Like, put computer to sleep after X minutes (hours). It's gone on my new 2018 MBP, while my 2011 had it. Does it automatically sleep the whole computer now if the screen blacks out (which would be dumb), or what are the rules these days? Never sleep, unless manually engaged? Seems dumb too, especially when on battery power!
SSDs don't need to be sleeped to the same extent that spinning disk drives do as their idle power consumption is typically a lot lower. But still, there's some power-saving to be gained by sleeping even a SSD, so why not, yeah? I don't know if MacOS actually sleeps SSDs though, or if Apple's own SSDs are capable of sleeping... That option could possibly apply to only attached USB/thunderbolt drives, possibly. 🙂
Yes I think it sleeps on it on. I checked on prevent from sleeping when display goes off. Cause I do with from home and hate that it would go to sleep Everytime my screen went off.
But anyone else have more insight.

According to Apple it does nothing on an SSD only computer such as your MBP...
“ Solid-state drives (SSDs) don’t have moving parts, so this setting doesn’t affect Mac computers that use only SSDs to store data.”

Seconded. It does affect external drives, so there is some benefit there.
I have this options enabled (HDD Sleep). I have power nap disabled (as others mentioned, why receive emails when sleeping?) and I have Time Machine disabled when on battery.
Ah okay. I don't have an external HDD so I guess I'm good to keep it checked off.

Yes, It really won't matter if you keep it checked or not if you have SSD only. I believe it will do an equal amount of nothingness in that situation 🙂

You can view the setting under /Library-->Preferences-->com.apple.PowerManagement.plist, which shows you the default time for the Disk Sleep Timer for both Battery Power and AC Power, but it is above my pay grade on how you unlock it for editing.
I wouldn't think I need to type in code to find this out. I hate messing with those things.

Me too. When I attempted to change it I got a message saying that it was locked and I didn't have permission to edit it and something about having to go into terminal and claim ownership or something like that. Thats beyond my pay grade 🙂
