Battery drain while sleeping

You imported a large number of old extensions when you migrated from your previous mac.

This was a bad idea.

If you had opted to migrate just the user accounts and not the other stuff, you'd start off with a nice system and leave all the old cruft behind.

I can't say which in particular are causing trouble, but extensions built for 10.9 or even 10.6 (in intel macs) are likely to not work without issues in Big Sur on an M1 mac.

You have Startup Items, which have been discouraged and deprecated for a looong time.

I strongly advise that you make sure to have updated Time Machine drive, then erase and install a clean system, and finally migrate ONLY the user accounts (not applications, settings or other files).

Hi,

We understand you're experiencing an issue with the battery life on your Mac. We would recommend the guidance in the following article that may help, including checking settings such as "Turn off “Enable Power Nap while on battery power”. This setting prevents your Mac from checking for mail or other iCloud updates during sleep which improves standby time.":

Hope this helps!

Have a great day.

Please run Etrecheck and post its full report here. Use the "additional text" button and paste the report into the text box.

It seems that things are getting great.

In intel macs, there is a setting called "Power Nap" that one can disable. I don't have an M1 mac to check, but I recall someone saying that this is not a thing in the new macs. Just in case, you may want to check the settings in System Preferences->Battery. Not that 3% is a very bad thing, but just to check all the possibilities.

You get ALL your data back.

You just reinstall fresh copies of the applications from the App Store or the developers' sites.

OK, first big unexpected improvement since reinstalling all: the MacBook Air now boots WAY faster than before! it is a much appreciated surprise of course, and it demonstrates that there was actually something wrong.

As per battery consumption: tonight It drained 3 percent, from 57 to 54. Does it sound acceptable to you? I can see it still had a lot of wakeups though.

do you think that importing NOTHING and just reinstalling everything from scratch would have been a better choice?

It would be a big pain in the ***, actually, but if it could solve the issue I would consider it.

In most cases, importing the user accounts is fine. This gets you all the documents, images, music, mail, etc. in place, and all you have to install is any applications, from the App Store or their developers' sites.

Only if that still causes issues would I consider not importing at all. That would be a great pain, indeed.

Hi there Luis, tonight, after many days of good behavior, my Mac lost 17%.

I don't know what did, I don't seem to have installed any new apps meanwhile.

Is there a terminal command I can run in order to check what drained the battery?

thanks.

no, it doesn't help at all,

your link mentions Power Nap but you should know that power nap feature is not available anymore in m1 Macs.

thanks.

Yes, like this.
