S22 Exynos Battery Drain on WiFi

Hi, I'm experiencing an issue with WiFi on S22 . When the phone is idle and connected to WiFi it can't switch to "deep sleep" mode and battery drains much faster then when on 4G. 

Is this a known bug ? Does Samsung is working on a fix ? I need to keep the WiFi turned off currently to reduce the idle battery drain, which is pretty annoying. According to multiple threads on Reddit and other sources online I'm not the only one with this issue

Does that meen it is an hardware issue?

I am really mad that this update didn't improve anything. 

I'm also having lip sync issues while watching video content (YouTube of mx-player etc)

I ordered an Snapdragon S22, sent back the exynos one. Its strange samsung keeps up with the substandard exynos for some markets.

Wonda have a few colours of the HK version, same goes for some German retailers (where i get my snapdragon).

Etoren has also the HK and E versions , bit pricey tho
