Macbook Pro 16" 2019 - 4 months old - Battery life impacted after Big Sur
I observed a considerable impact on battery life after the Big Sur update.
My battery life has dropped from around 8 hours to 3 hours
I cannot hold a charge while using an external monitor anymore (even with the massive power adapter plugged in). My Mac would ultimately run out of power before the close of business.
The system runs extremely hot
Massive power drain noticed while using any video conferencing app such as Hangouts, Zoom, Teams, etc.
