What is the reported battery life of your P2 Max devices with Windows 10?
Mine is reporting a life of about 5.5 Hrs roughly with the following settings:
- Screen resolution set to 1920 x 1200
- Windows Battery Saver On
- BIOS TDP Profie with **Fan** : Standard Mode
- **TDP** : Energy Saving Mode
I feel that 1920 x 1200 is pretty much sufficient on the display of this size.

I did a lot of tests and there are results:
just to understand names
25/50/100B - brightness level (resolution was native)
0/25/100CPU - power mode (in default balanced plan)
no prefix - wildlife.wmv video playing time
edge prefix - special script that opens randomly 10 tabs in edge with intervals 30-120secs
FFV - Final Fantasy XV bench in Lite 1080p loop mode
I did this on BIOS 0.20, after add additional tests with new 0.23 (low/std power in BIOS)
As you can see - most important part of battery life is screen brightness.
