PS5 DualSense Controller Test

The DualSense lightbar is controlled by the host system. Browsers do not expose lightbar control through the Gamepad API, so the bar will sit at its default color (usually blue) for the duration of the test. This does not affect any measurements.

The browser can read trigger pressure values from 0.0 to 1.0, which is enough to verify the trigger physically moves through its full range. Sending force-feedback resistance back to the trigger requires a native driver and is not exposed to web pages.

Yes. The stick drift test samples axis values for several seconds with the sticks at rest. Any reading above 0.05 indicates drift the operator can feel in-game; anything above 0.15 typically requires module replacement.

DualSense controllers enter low-power sleep when no input is detected for several minutes — Windows often interprets the sleep as a disconnect. Either keep one stick lightly engaged during long idle periods or run wired over USB-C to eliminate the timeout.

No. The standard DualSense uses potentiometer-based sticks, which is why drift is the controller's most common long-term failure mode. The DualSense Edge also uses potentiometers, though its swappable stick modules let you replace a worn unit without a full repair.

Yes. The Gamepad API exposes the touchpad as an additional input surface on the standard mapping. The touchpad test reads position and click state in real time, so both the swipe surface and the mechanical click switch can be verified independently.

Sony specifies 12 hours, but real-world battery life ranges from 6 to 10 hours depending on haptic intensity, adaptive trigger usage, lightbar brightness, and speaker output. The Battery Health Check tool tracks the trend over multiple readings to estimate degradation.
