I managed to reduce my standby drain from 3000W to ~500W, by generating a sleep study for the entire 28 days allowed. I then found the time when it started going "bad", and uninstalled the software that I installed around that time. Turns out Labview was the curlpit for me. But now I can't use labview. There's still nohwdrip.c8 causing some drain, but it's much lower. S3 sleep would indeed be welcome.

I'm on the most current update, KB4284848 (June 26), and still having 0% hardware DRIPS (NoHwDrips.C8 still showing around 97% active during sleep). Draining about 2-3% per hour in sleep. [correction in next post below]

Not sure if it was the BIOS update to 1.25, or the windows update that installed today, but I'm finally getting proper sleep mode in Win 10. Seeing HW DRIPS above 0% for the first time. Also 0% battery drain in 1.5h of sleep. Fingers crossed that this continues.

I have all available updates installed from Microsoft and Lenovo. I will do a new sleepstudy since I had the laptop reconfigured to hibernate on all conditions since sleep is not working on the X1 Carbon 6th gen. My guess is that is has to do with which programs are running on the laptop when sleep is initiated. I use the EmClient as email program and everytime I resumed from modern standby it reported corrupted databases. Also virtualbox did't play nice with VM's misbehaving when resuming from modern sleep.
Normally I would not put a laptop to sleep with VM's running, but the problem is with modern standby that the laptop goes to sleep irrespective of the settings the user has chosen in the Windows power settings. I also want to keep the laptop on running certain applications like VM's with the screen off. Now I dim the screen to minimum with a screensaver on, but it seems very '80s and backward...
Has anybody found a way to keep a laptop with modern standby on with the screen off?

Is everyone here having problems on the "1803" version of Windows 10? A Lenovo guy I was working with wasn't able to repro it but wasn't on the newest version of Windows 10.
(To find this press: "Windows-X button --> System" then look for "Version")
