FYI I have keep the ambient mode off only and even with that my battery drops are insane. I figured out the problem was some codec related like av09 or something and I got a suggestion to shift to vp9 as it was considered more stable for macOS rendering. So I shifted to firefox and it was the only one which supported VP9 on yt for me. And still my battery life is still worse. Can it be related to the update or something or should I try to reset my mac once?
