Use the guided tester to record observations. Browser response measurements are not hardware latency or true USB polling-rate measurements.
Open the controller tester →What the symptom tells you
Stick drift describes unwanted movement when the stick is released. It does not, by itself, identify a damaged sensor. Input mapping, settings, calibration and physical condition all deserve investigation. A browser test observes the reported input, not the component inside the controller.
Measure the resting position first
Place the controller on a stable surface, release both sticks and run the guided center check. Repeat after gently moving and releasing each stick. Record whether the offset is persistent, intermittent or changes direction.
Keep the connection and software settings consistent. A demo result is simulated and must never be included as evidence about your own controller.
Range and circularity answer different questions
A range check observes where a stick can reach. Circularity describes the recorded outer path against a circular reference. It is not the same as resting-center drift. Finish the full sweep before interpreting the result.
There is no universal circularity percentage that proves a controller is healthy, worn or counterfeit. Firmware, mapping and the test method affect the trace. Our earlier percentage-based failure categories have been removed.
Deadzones and calibration
A deadzone can suppress small reported movements in the game or software that applies it. That changes the response and can hide a symptom; it does not establish that a physical defect was repaired.
The reference deadzone in this tester is a visual comparison. It does not rewrite your game or controller settings. Hardware calibration is a separate operation for supported devices. GamepadInsider’s calibration still needs physical-device verification and should not be presented as a guaranteed fix.
When to seek support
If the symptom persists in multiple supported applications, save your observations and consult the manufacturer’s model-specific support process. Follow the device manual for cleaning; do not pour cleaning fluid into the stick opening. Contact support before attempting invasive repairs, especially when warranty coverage may apply.
