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!!
Big sir you can take the big sur issue to Microsoft and Opera to resolve. That’s not what I’m prepared to do
i had previous versions of OS, no problem at all. Upgrade vs update —> I simply downloaded new version and updated.
Of course

Is that simply in response to my question:
«Do you have Automatic Updates turned on, for your Mac App Store purchases?»
What of my other questions?
Also same won’t charge. Will Apple compensate us for this excessive wear and tear on our devices?
That update didn’t change anything for me
Anyone found an actual fix? This is f*cking appalling, it's been months of complaints from people around the world and Apple has yet to address this.
I am experiencing the similar issue, with a 2019 15-inch MacBook Pro with an intel i9 chip on macOS 11.0.1. According to iStats Menu, even if I am doing nothing, the temperature of my CPU never gets below 50 and sometimes spikes to 70 degrees celsius . If I use screen mirroring, it will get super hot and drains battery quickly. If not on AC power, the battery life when I am just editing files in Pages also shows a notable decline. Tried several ways to solve it including boot into safe mode or a hard restart but did not work. Will go to Apple Store tomorrow.
If you are synchronizing between a device with a significant Safari History vs. one with a recently wiped Safari History, I would expect significant Network activity (perhaps more so than CPU use).
If this network use is wireless, especially if not very close to the base-station, that can be a significant power drain, in itself.
Do you see any such corresponding network activity with Safari iCloud sync turned on?
I updated to Big Sur 11.1 yesterday, without a single “hiccup”. (Admittedly, I have had no troubles with 11.0.1, either.)
I know it has fixed a number of issues many have been having (though, admittedly, not all).
I have a brand new 2020 MacBook Pro 13inch which was upgraded to Big Sur 11.1 but since then I have not been getting a full use out of the internal Battery and do you think that this is a warranty issue

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
Did you upgrade to Big Sur right away, or only after you had installed software and files?
(Sounds like you had been using your Catalina macOS for a while, before upgrading to Big Sur, as if it were just another update, without any thought about whether your software would be compatible with the brand new Operating System [OS].)
Note: clean installs of Big Sur has never caused anyone any issue: battery or otherwise. (Well. With the exception of some people adding monitors to M1 based Macs.)

Apple has not «stoped Supporting Mac OS Catalina because of the realese of Big Sur».
Even all macOSs back to High Sierra are still supported by Apple, with only High Sierra going on the “no longer supported” list, sometime soon.
I’m sorry if you so misunderstood the nature of the release of the major Operating System (OS) upgrade of Big Sur. Big Sur is certainly not a mere update.
In fact, Apple considers Big Sur to be such a major OS upgrade, that they increased the major version number, from 10 to 11, for the first time since 2001!
The distinction between an update vs. and upgrade is quite important:
Note: No one should install an OS upgrade without checking the compatibility of their own software, with the new, upgraded OS!
I’m sorry to say this, but since you simply treated this major upgrade as if it were a mere update, you are “reaping” one of the consequences, due to third-party software incompatibilities.
In the case of Big Sur (and some OS upgrades, in the past), rather than having so many third-party programs simply “bombing” or refusing to run, they are running, but are “confused” by the changes in their operating environment: this has caused some to “run amuck”, using a great deal of computer resources (usually CPU) for no productive result!
Please read the Solved comment, in this Discussion, for information on how you, too, can solve this issue on your system.
Please do keep us informed of how things go, or don’t, for you, in this “hunt”.
We are here to continue to support you as best we can, in helping you find and fix the issues you find.
This is my battery drain when asleep since installing Big Sur, happens every night. No reported battery issues, or anything showing as high battery usage. Hope there is a patch soon.
Thanks, Snagel1956.
While Google Chrome is not a universal culprit, it is an example of what can happen with incompatible third-party software.
