Battery drain on my macbook post catalina os 10.15.1 update

In my case the same problem started to happen from Mojave.

I did everything like removing incompatible app, killing unnecessary background processes, optimizing display brightness, SMC reset, reinstallation of macOS etc., but none of them worked.

I finally "clean" installed macOS, where "clean" means formatting the disk completely before installing, and now the problem seems like has gone.

Of course it requires lots of effort and actually I'm still in process of reinstalling all the apps and documents back, but I see this is the only way to go....

Hello tinafromog,

Thanks for reaching out in Apple Support Communities! I understand you're having trouble with your battery life since updating to macOS Catalina. I'm happy to assist you with this.

Let's take a look at this article and follow the recommendations to optimize your battery. Give it 24 hours after making changes to see if you notice any difference: About Mac notebook batteries

Thanks for using the Apple Support Communities, and have a great day!

I, too, have a problem with worse battery life after upgrading to Catalina (Macbook 13" early 2015)

Mojave gave me 9-10 hours of battery life easily, now it's about 5 hours tops. Will definitely try to downgrade to Mojave and see the results.

Same problem with Macbook Pro, Retina, 13 inch, Early 2015.

After Updating MacOs Catalina 10.15 to 10.15.1, battery is draining very fast. I checked out monitor and there were not something processing with more cpu and memory, everything is normal, but the battery still draining fast.
