Hi everyone! After upgrading my MBP 16" 2019 to Big Sur, I am facing shorter battery life than on Catalina. It's worse about 30%. My battery is in a pretty good shape - 58 cycles. Any idea what to do? Will the next update fix the problem? Thanks!
PS: I saw people having same problem at reddit.
MacBook Pro 16″, macOS 11.0
I previously said that I was experiencing the same issue. I went to Genius Bar and they told me to wait for future updates since my battery draining might be caused by some compatibility issues. Today, I accidentally noticed that a process from "Karabiner-Elements.app" is occupying a great amount of CPU usage (this is an app used to customize keyboard functions). So I tried to uninstall it and it worked. Now my Mac has returned to normal (see pic attached). It turned out that my "Karabiner-Elements.app" was not updated to the latest version to work seamlessly with macOS Big Sur.
So my suggestion here would be to:
First, check App Store for app updates;
Second, check the official website of third-party apps you downloaded from web to see whether they have updated their apps for macOS Big Sur. If not, you can try uninstall them to see whether it will help (if the app is not a must-have for you).
Lastly, if software side is okay, try running system's hardware check to see if there is something problematic.
Hope this can be of some help to you!!
Glad to hear that your system is running better under Big Sur 11.2.1, oandor1.
Do you have {Automatic Updates” turned on for your software (especially your third-party software)?
That will help, over time, as your software is updated.

What is that image supposed to be showing us?
Is your MacBook not charging (even though the Battery icon seems to be showing that it, supposedly, is)?
Or is it that you are experiencing such high energy use, that the charger cannot keep up, when your MacBook is in use?
Have you tried the recommendations in the comment marked “Solved”, here?
Other than the Charging issue, in only certain MacBook Pros, the latest Big Sur update (11.2.1) will do little, if anything—by itself—to solve the High Energy use issue.
my macbook heated up like 2 mins after i turn it on and the fan went crazy.
Same here. My battery has been draining like crazy since updated to Big Sur. Wish I hadn't done that @.@
I've found some solutions online here, but I doubt they will fully solve the problem.
Exactly the same here with my MBP 13” 2016, everyday I’m having to recharge it, as overnight the battery has completely drained. Something is different with Big Sur for sure.
Further testing proved that I'm back (more-less) to the original performance.
Got about 2.5h on 50% battery with about 30mins on the last 10%.
I’m not sure I have safari iCloud sync disabled and I’m still suffering. Nearly full battery last night and this morning my 2016 MBP 13” was showing just over 50%.......something is not right???
Thanks but I don’t understand your comment? I had no problems with installing BS, it went like a dream as usual and as of last night I have not seen an update for BS yet?
Very good advice, Orange_Lu!
İ too am very relieved. Do you recommend updating to 11.1? I have not yet done so.
🤞🏻👍🏻
it is the 2020 intel version and came with Catalina and the battery was lasting a long time and I have upgraded to big Sur and the battery has been draining fast
This severe battery drain happens even while my MacBook Pro (2017) is sleeping!! I close the lid at night with, say, 70% charge, and by morning it's down to 20 or 30%. Do you have any ideas for that?
Conspiracy theorizing helps no one, mmabood.
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
