Windows 10: My Acer laptop battery drains while in standby screen closed.

I have run both the battery report and the sleep study but neither one recognizes the discharge that occurs during sleep. So I am not getting any info there on the possible cause. Connected Standby is not supported, per the report. Typical scenario is I close the laptop in the evening with 60% battery left. Starting in the am it initially reports ~60% but within a minute it refreshes that to something close to zero and abruptly goes into hibernation. Any clues to TS this?

I don't know.

If you checked it really was sleeping when you thought it was then I'd suggest running a battery report to see how degraded the battery is.

High battery drain during Modern Standby sleep, no obvious culprit

I take a different approach from Denis. Rather than trying to disable Modern Standby I adapted it to suit my needs.

I have two 'almost new' laptops. One supports Modern Standby, the other (cheaper) one doesn't.

While I cannot remove Modern Standby, I could tame it. To save on battery power I like all my laptops to sleep (or standby) on closing the lid, then hibernate after 20 minutes if I don't return to them.

My first step was to reduce power drain in modern Standby by disabling network connectivity in Modern Standby.

Next I set Hibernate after in Power Options. This setting is missing by default on a Modern Standby install of Windows 10/11, so first add it back.

Then I could make my Modern Standby laptop behave like all my other machines.

 

the battery is getting drained

i have:-
The following sleep states are available on this system:
Standby (S3)
Hibernate

it also says:-
Standby (S0 Low Power Idle)
The system firmware does not support this standby state.

so why was the battery getting drained when the laptop was sleeping?
