Big Sur battery drain

Petrie1:

Is that an M1 based 2020 MacBook Pro 13inch, or an Intel based one?

If an Intel based one, did it come with Big Sur preinstalled, or did you upgrade to Big Sur (pre-11.1), yourself?

How did it behave before migrating your data and settings and software?

It is an intel Based 2020 MacBook Pro 13inch with Big Sur installed by my self because Apple Have stoped Supporting Mac OS Catalina because of the realese of Big Sur and it is 1.4 GHz Quad-Core Intel Core i5 with 16GB LPDDR3 Ram and a one 1TB flash storage . and here is the example of the battery drain

companies are not held responsible and that's the problem.

I bought my new laptop a couple of months ago and after this slurry Sur upgrade that I really didn't want to take, but felt like being forced by Apple, battery life is even less than any average no name laptop.

And yeah you the customer is wrong, because as the Apple's response foolishly says, every major upgrade has cost and we must be happy about our laptops dragging their feet, because the bloody no 10 is now called 11 and the goal post is changed once again.

Well, Alan Cook2, “obviously”, your MacBook Pro (2017) cannot be truly «sleeping!!»—as in having its CPU being in the “sleep” state—unless you have a hardware issue (a short-circuit, somewhere, such as internal to the battery).

However, the MacBook will continue to run background processes (processes without a Graphical User Interface [GUI]) even when “put to sleep” (such as being “clamshelled”).

So. This still fits nicely into the context of the comment marked “Solved”.

Have you tried the recommendations within the “Solved” comment?

We, all as fellow users, are here to help you track down the errant background processes.

Hi all,

I have the MPB 2020 with Intel, having the same issue even with latest Big Sure and keeping system connected with power for 48 hour, same it was directly after the big sure release date.

i tried resetting all SMC, all other short names Pxxxx, nothing helped.

Window server in activity monitor with one opened window consumed about 20 percent of CPU, Safari about 13 percent.

any suggestions how to get back battery drive? Is there any way for to re-start housekeeping, so I can solve it forever?

thanks

We were told Apple is working on the issue of the new operating system and that any new updates requires more power temporarily. Months on and yet this issue is there. The later update released didn’t solve the issue.

we are supposed to believe that this operating system update has been such a great development after so many years that the revision number changed big time.

However, I would like to call the situation a major mess up. My newly purchased expensive Mac Pro is turned into an ordinary laptop. That’s all into it for me.

What sort of clamshell processes could be going for months? Is this a spy and surveillance operation? Is all my data getting shipped to Apple? Is this the reason for the laptops becoming more popular, so nobody can truly turn off their devices?

I’ve got no extra ordinary amount or types of apps. MS Office and Opera and the rest are Apple provided applications eg Mail.

Besides I’ve been using these applications in the past and on my older Mac.

are we supposed to call all other applications the problem to say Big Sur doesn’t have an issue?

No wonder about the big sur issues. It’s the Apple people that are the source of the issue trying to misread and mis comprehend my posts to blame something else but themselves

I’m simply a fellow user, like yourself.

Please help me know what I misread or misinterpreted.

Big sir you can take the big sur issue to Microsoft and Opera to resolve. That’s not what I’m prepared to do

Microsoft has already produced versions of MS Office that are compatible with Big Sur.

As for Opera, you simply check for upgrades/updates.

Do you have Automatic Updates turned on, for your Mac App Store purchases? That will help make things easier.

So this is my activity monitor, one tab open in Safari. I reseted all SMC, P..., have the latest update. Having the computer in the power for 48 hours, cleaned Safari history, clean all via CC cleaner... but still not getting back Catalina battery. any suggestions? I did my update via Software update (About this Mac). Any suggestions?

thansk for reply.

basically I had all as I had in Catalina, basically no change in settings (expect of I turned off power nap on battery, which I had on Catalina). I have same networking as on I had on Catalina, so basically nothing changed.

I had mac on like 2m on when doing this screenshot.

Maybe question --> does the Mac do the Big sure housekeeping when on power supply, but it closed? Is there any way how can I re-start the "house keeping?"

thanks for help

I don’t know why you have now asked about «re-start[ing] the “house keeping”» twice, now.

The «”house keeping”» only runs as needed, such as when you “dump” a bunch of files (or photos, or such) on your drive.

Are you saying that your MacBook was only powered on for two (2) minutes before you obtained that screenshot of Activity Monitor? If so, you missed the high CPU, and even high GPU usage, beforehand.

The question, then, would be how often this happens as you are running on Battery. And what else is going on, during that time.

(Note: it does seem to be somewhat normal to have a burst of high CPU usage right after boot-up—maybe even a bit of high GPU—but that is only for a matter of seconds.)

here I attach the activity monitor with notebook on battery 20 minutes, with at least 15m with no activity (black screen, opened notebook). There is just one tab in Safari opened (komentare.sme.....), for me it seems it takes a lot of power (99),above highlighted, but I am not expert.

Feel free ask any questions

Other than your open webpage, there’s simply nothing there that is using a bunch of your computer’s resources, Stanley22.

WindowServer, obviously, had some time where its CPU usage was somewhat high, if your computer was actually booted only 20 minutes before this. (You only stated 20 minutes on battery. You didn’t say how long since boot-up.)

(Similarly for kernel_task.)

Depending upon what that webpage is doing, the 16.1% CPU currently being used by the WindowServer could be, mostly, to support that webpage. (Activity Monitor’s screen updates also go through the WindowServer.)

By the way, the percentage of CPU is not the percentage of total available CPU, but only the percentage of a single CPU core, on your machine.

Hence, the total available CPU is 100% times the number of CPU cores, on your machine.

So, 100% need not be all that high, depending upon how many CPU cores your system has.

Note that your entire system was 80.48% Idle, at the time of your screenshot.

(I have certain tasks that can use up to nearly 400% CPU, on my four core Intel based Mac mini, and as much as 750%, so far as I’ve seen, of my eight core M1 based Mac mini.)
