Detailed description:
I got this laptop a few days ago. Everything is great except the battery. It only lasts 2 hours of browsing the internet and using OneNote. I use whisper mode and battery saving mode but it didn't make the battery life better. I expected 6+ hours of battery life and not just 2. Please tell me if this is an issue with the OS or with the laptop itself.

Hello. I was using Microsoft Edge and OneNote at the time. I am using the Whisper Mode, with 40% brightness. I had Bluetooth off but Wi-Fi on. No updates were installed in the background.

Please charge fully and start operation until the battery is 20% left.
Run powercfg /spr with powershell, then provide sleepstudy-report.html data to us for confirmation.
Sorry for any inconvenience it may be caused.

Sorry for the late reply - Looks like the preinstalled McAfee app was using so much battery. I uninstalled it and now the laptop lasts around 5 hours on battery.
