That is by design, it's a feature from Intel and Microsoft called "modern standby." It basically means your laptop cannot actually sleep anymore. Instead, it enters a slightly-lower-power mode so that it can download emails in the background, run Windows updates in the middle of the night, and generally pretend to be a phone even though no one wants that and the hardware/os was not really designed for it.

Modern Standby requires that deepest sleep states take less power than S3 standby, the issue is mainly drivers and applications either waking the system or not putting peripherals into deep enough sleep (or shutting them down entirely if possible)
