'modern' standby battery drain...
I don't know who thought this modern standby feature replaces the S3 sleep mode, but it does not.
I have a XPS 13 2-in-1 7390 with windows 11. When I put it in sleep mode it will drain about 6% per hour
What I already did/tried :
- regedit trick to show the "Networking connectivity in Standby" in the power options panel. Set 'Disabled' for both. "powercfg /a" indeed returns "The following sleep states are available on this system: Standby (S0 Low Power Idle) Network Disconnected". But as per the image below, I'm not sure that windows tells me the truth.
- The regedit PlatformAoAcOverride, but when resuming from sleep, it just freeze on the Dell logo.
- Both with AC/on battery when entering sleep mode gives the same result.
- Maybe more but I can't remember
What to do to solve this battery drain issue, as neither Dell nor Windows will make S3 mode available (unacceptable btw...).
Thanks

I don't have your machine, or even a newer version, but it appears you seem to have a graphics and NVMe controller staying active.
Do you have any sense of what it is doing during those periods?
Normally, in low power mode, my older system would burn around 2% to 3% of the battery until I let it go into hibernation.
You might check the Device Manager and look for the NVMe controller and the Graphics to see if there is some type of power management tab on those devices.
You might also, in the Device Manager, highlight the PCI Express Root Port #9, then change the view to "Show by connection", which may give some info as to what devices are involved.
I don't think messing with the registry will do much good and may even hurt.
