If nothing suggested by the others helps and If you want to report this to Microsoft use the Feedback Hub app in Start Menu where developers are tasked to process consumer feedback. They will not even see it here. This is a tech forums staffed mostly by volunteers trying to help others with your problems.

Additionally, to make sure it gets seen if you're a Windows Insider you can report it in the Windows 11 Insider forums here which is monitored by developers:

I hope it helps.

I recently upgraded from a trusty Thinkpad T430 to a Lenovo Yoga Slim 7 Pro (Ryzen 5800H) with Windows 11. I am appalled every morning to find my laptop hot and even spinning its fans if plugged in, or during the day to pull it out of my backpack and feel some warmth with 5-10% less battery life. I have no idea who thought that a professional machine with a hungry x86 processor should behave as a smartphone and be constantly on.

Sadly, my researching online has led to no way to disable completely Modern Standby and bring S3 Sleep back. Even the system reports it doesn't support it:

Is it really possible that a laptop cannot sleep or is it just somehow disabled in the registry? What can I do to enable S3 sleep?

Many thanks

Well as a start its a very bad idea to leave your device in sleep overnight, for many varied reasons. The device should be shutdown overnight

You have updated drivers etc with the Lenovo update utility?

A system in low power mode should not be running fans or getting how. You need for check what a sleep study report is and spend some time learning how to read it.

powercfg /sleepstudy

Copy the report to the desktop and open with a browser. Make note of where the report is kept after running the process.

Also be aware certain Bluetooth devices can wake the system up. Possibly, something else is also capable of bring the system out of low power mode.

Thanks for the advice. I have done that multiple times and never found an explicit culprit. For instance, here are 23 mins of sleep that cost me 5% battery... The "top offenders" don't say there is anything

here is a a bit more info:

• the Windows push notifications service has been active

• the CPU has had "non-attributed" time

This network activity is exactly why I want to completely disable Modern Standby. I do not want my "sleeping" laptop checking emails, chats, indexing file systems or scanning for viruses. At the very least, I want to disable the Network-connected side of Modern Standby. There seems to be no way to do it though.
