2018 15" i9 slow to start charging after Big Sur update

[e1me5]

I've noticed that after updating to Big Sur (11.0.1), my 2018 MBP takes a couple of minutes to start charging its battery after I plug in the apple power cable. Although it chimes when I plug it in, the power indicator switches to an icon with a power plug and says not charging and only after a couple of minutes or more it changes to the battery with bolt icon that indicates the charging process. This happens on all 4 TB3 ports and I wonder if its something software related rather than a hardware problem. Battery is kinda new, it was replaced in July after the previous one was swollen and bent the chassis. But after only 5 months health dropped to 88%. Anyone else having this problem.
