Ever since I updated to Big Sur, I've noticed my battery life on my intel MacBook Pro 2020 13 inch is quite poor. It lasts about 4 or 5 hours from full to 0 when I'm web browsing (I always use safari). This is far below the 10 or 11 hours or so reviewers seem to get on the device. I got coconut battery so I know I'm 200 cycles in and the battery is at 87% capacity so it's not battery degradation. I've reset SMC and PRAM multiple times to no avail. I also can't find a good source of the drain, my activity monitor doesn't show any processes taking up huge CPU usage, I see no more than 20% use when I'm using Safari.
I have no idea what to do here, has anyone faced this problem and knows a solution??
