Incredible battery drain in new Ventura 13

After I updating my macOS from Monterey to Ventura I am struggling with an incredible battery drain in sleep mode. I've already tried to change many options and even closed all my apps before entering a sleep mode. What I noticed in Activity Monitor is the fact that both kernel_task and WindowServer use a lot of CPU % and make a lot of wake-ups, but I suppose it is ok. Do you have the same issue with a new system?

I have called Apple several times since February of this year when the problem started to happen. I spent months doing steps with them. Downgrade, SSD partition, reinstall Mac OS several times, among other unsuccessful steps. After these 8 months, I managed to change the logic board, trackpad and battery. I can't say what the trackpad is related to the problem, but I've already left the Mac in for assistance and I hope it works with this more aggressive attempt. Air m2.
