Z13 Flow 2025 Battery Life

I am curious to know if anybody tested here, I am testing since yesterday and with the following settings:

Model: 395+ 128GB RAM
Profile: Silent
RGB: low
Volume: 40%
Brightness: 50%
youtube video 4k continuously playing
WiFi: ON
BT:ON

I am getting 7h to 7,5h

I am curious as I saw many ppl saying 10h etc... so either I am doing something wrong or I am missing something? or... those reporting 10h used different settings?
