battery drains so fast
Hello everyone! I've noticed an immense decrease in battery's health. I have a 2020 13th inch macbook pro 2.0GHz quad-core 10th-generation. It used to last for over five hours few months ago but since I've upgraded the BigSur it wouldn't last three hours and with watching shows it barely make 2 hours. This is so frustrating. Yesterday I worked on my laptop and I had to stop working after two hours. This is causing real troubles for me.
MacBook Pro 13″, macOS 11.1
