To get reasonably accurate results your device and browser need to be focused on the benchmark. Here are some basic instructions to allow that:
- Ensure you are running the latest stable browser version.
- Prefer using a separate clean browser profile — extensions and non-default browser settings can have a large impact on the score.
- Don't run any programs in the background.
- Restart the browser and close all other tabs and windows.
- Keep the Speedometer page focused and do not interact with the device while running the benchmark.
- Keep your battery-powered device plugged into a charger.
- Some devices might need time to cool down between between consecutive runs.
