Battery Life Test Methodology

How we test battery life:

• The screen is set to 180 nits of brightness
• If the device has an iGPU-only mode, this is activated
• If not, the test will be executed with the standard NVIDIA Optimus / Advanced Optimus / Auto mode settings
• All battery-saving features that don't decrease visual quality are applied.
• This includes:
  • Best Power Efficiency mode and Energy Saver mode in the Windows Power & Battery Menu
  • Variable Refresh Rate (if present, that's a display/laptop dependent extra)
  • Panel Self Refresh (if present, that's a display/laptop dependent extra)
  • The most energy-efficient mode is selected by the manufacturer's own software that controls the notebook's power

Settings Used

To maximize the battery life of this gaming beast, you could use the following settings:

• Open the NVIDIA Control Panel and select "Optimus" or "Advanced Optimus" mode. This will switch the graphics to the iGPU.
• In the Razer Synapse app, select the "Balanced" preset and tick the "Switch laptop screen refresh rate to 60 Hz when on battery" option
• Apply Best power efficiency + Energy Saver Mode in the Windows Battery menu
• Screen is set to 180 nits.

I'm pretty impressed with the battery life of this device. The 90 Wh lithium-ion unit has enough juice for more than 8 hours of 4K video playback on a single charge. This is a respectable result, especially for a gaming notebook with a 16" high refresh OLED screen.
