Battery drain on my macbook post catalina os 10.15.1 update

Hello, has anyone had this problem with their macbook air battery life drain post catalina update? I used to be able to use my laptop battery for 8+ hours, but now my battery drains so quickly I can barely eek out 2 hours.


If there's any fixes, I'd greatly appreciate your help. Thank you!

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....
