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?

2021 MacBook Pro 16 Battery Health 93% after 6 Months Hi, I have read numerous articles on the community, but either their batteries are not depleting as quickly as mine or they are dated (like a few years ago), so I thought I want to bring my case to attention and see if it is normal that this is happening. Model: MacBook Pro 16" (2021) (M1 Max) Battery Health: 93% Cycle Count: 61 Purchased / Start using: July 2022 (6 months ago) I have been aware about the battery health precautions so I do the following few things daily: I use the official Apple Charger (140W) and the MagSafe cable I have battery management turned on Reboot my Mac from time to time Run mostly on power adapter but will still use unplugged from time to time I believe I am already doing all the right things here to preserve the battery, yet at this rate 7% per half a year, I will be at 72% at the end of the second year?! Can I be advised on whether this is normal or should I send it in to Apple? Thanks!

Likely something running the background. When you do a major OS upgrade, spotlight will reindex your internal storage and that can take a few days.
