Device & Browser Information Testing

Depth resolution: technical details of equipment information testing

In modern Web development, understanding the user ' s equipment environment is a prerequisite for providing quality experience. Various APIs available via browser (e.g., Navigator, Screen, Battery Status API etc., we can access a wealth of hardware and system information.

Meaning of core parameters

• Device pixel ratio (DPR): The ratio of physical pixels to logical pixels. On high screens (e. g. Retina), the DPR is usually 2 or 3。 Developer needs to load images of different resolution based on this value to ensure visual clarity.
• CPU Core Numbers and Memory: These parameters reflect the computing capability of the equipment. For calculating intensive Web applications (e. g. video clips or 3D) Rendering) allows for the algorithm complexity to be adjusted by the dynamic of this information.
• Battery status: Allows application of lower backstage synchronization or visual features at low power, thereby extending the user ' s flight time.

Privacy and security tips

Note: While this information can help to improve the experience, it can also be used for the "browser fingerprints" tracking. Our tools are only locally displaying this information and will not upload it to any server. To protect your privacy, it is recommended that browser privacy models or tracking-proof plugins be used when accessing untrustworthy websites.

How can this information be used to solve problems?

Scenario one: The website displays anomalies on specific devices. You can check the window size and screen resolution to determine whether it is due to inappropriate media query (Media Queries) settings. Scenario 2: The web page is very slow to load. Check the bottom bandwidth of the network connection section RTT。 If the network environment is poor, you can consider starting light mode or optimizing the resource load path.
