Browser-side diagnostic only. Connect the controller in your operating system first; this page cannot pair Bluetooth or install drivers. Results depend on the browser, operating system, connection and controller mapping.

WHAT IT CHECKS

Measure the signal, not the guess

Use this joystick drift test to find movement that appears while the analog stick is physically at rest. Compare the live X/Y signal, center offset, jitter and circular range before deciding whether a controller needs cleaning, calibration or repair.

  • Joystick center offset while untouched
  • Deadzone and small unwanted movement
  • Jitter or unstable analog readings
  • Movement and angle coverage across the full stick range
HOW TO GET A CLEAN RESULT

Test conditions matter

Use a wired connection when possible, close other controller software, and press a button after the device is connected.

  • Connect the controller before starting the test.
  • Leave both sticks untouched while clicking Calibrate center.
  • Move one stick at a time during the circle test.
  • Compare USB and Bluetooth readings if the result is unexpected.
Privacy by design: input data is read and processed locally by your browser. It is not uploaded to a server.

FAQ

Questions about this test

What is a joystick drift test?+

A joystick drift test checks whether an analog stick reports movement while you are not touching it. This page measures center offset, jitter and deadzone-related movement from the browser Gamepad API.

How do I test joystick drift?+

Connect the controller, leave both sticks untouched, click Calibrate center, and wait for the readings to settle. Then move each stick through its range and run the circle test for a fuller check.

What is a normal drift reading?+

There is no universal number because controllers and games use different ranges. A stable center, low jitter and no unwanted movement are more useful than one universal threshold.

Can software fix joystick drift?+

Increasing a game deadzone can hide mild drift, but it does not repair worn hardware. Cleaning, calibration or replacement may be needed for severe drift.

Is this a professional hardware test?+

No. This joystick drift test analyzes the values exposed by your browser through the Gamepad API. It is a practical diagnostic, not a certified hardware measurement.

JOYSTICK DRIFT GUIDE

How this joystick drift test works

A browser-side check for unwanted analog movement, not a firmware repair tool.

01

Connect and center

Plug in or pair your controller, press a button, then leave both joysticks untouched. Click Calibrate center so the test can compare later readings with the controller's resting signal.

02

Watch the signal

Center offset shows how far the reported stick position sits from its reference. Jitter shows small fluctuations while the joystick is still. A moving value at rest is the clearest sign of drift.

03

Check the range

Run the circle test and rotate one stick around its edge. Angle coverage and radius consistency help separate a center problem from a limited or uneven analog range.

LOW OFFSET

Healthy center

The joystick stays close to its calibrated center and the jitter reading remains stable when untouched.

UNSTABLE SIGNAL

Watch the jitter

Small fluctuations can come from hardware wear, wireless noise, mapping software or browser sampling. Compare USB before drawing a conclusion.

DRIFT FOUND

Unwanted movement

A persistent offset above the displayed threshold means the browser is receiving movement at rest. A game deadzone may hide it, but cannot repair the hardware.

WHAT TO TRY NEXT

Need a deeper check? Use the browser calibration test for a fresh reference, read the controller connection guide, or compare a specific controller profile.
