Is it the same with macOS Monterey?

Ever since I updated to bigSur, the battery drain in sleep mode is just horrible. Previously when I had macOS Catalina, I would lose only 1% at max when I put my MacBook Pro (early 2020 model) to sleep. But in Catalina I'm losing almost the full battery. Will apple solve this issue or should I downgrade to Catalina again? This is a new Mac not even 6 months old and such performance is not acceptable at all!!!
