Devices

⚡️ SpeedVitals offers various different device configurations in order simulate the specification of various real-world devices.

Each Device Configuration has its own Performance Throttling, Network Throttling, and Screen Size.

info

⚡️ SpeedVitals doesn't perform the test on an actual device. We simulate their screen size, performance, and network capabilities. This behaviour is similar to Google PageSpeed Insights.

Here's the configuration of all devices available:

We have also calibrated the CPU Throttling of devices with respect to the performance of the actual device and our server hardware.

The network connectivity is selected in a such a way that it matches with the internet connectivity of average user running that specific device based on demographics and economic factors.

tip

As to the difference in device resolutions, your website may have a different LCP & CLS Elements for real-world devices. To discover all the different LCP & CLS Elements in Lab Testing, we recommend testing with ⚡️ Multi-Device Batch Test.
