How to Use This Gamepad Diagnostic Tool
- Connect: Plug in your Xbox, PS5, PS4, or PS3 controller via USB or pair via Bluetooth.
- Activate: Press any button (A/B/X/Y) to wake the browser's gamepad driver.
- Analyze Sticks: Rotate thumbsticks slowly. Look for stick drift (movement when untouched) or "jitter."
- Check Buttons: Press every button. If a button stays lit up on screen, it may be "sticky" or conductive pads may be worn.
- Test Rumble: Click "Vibration Test" to ensure your motors are functional.
Controller Diagnosis & Quick Fixes
Test for Stick Drift Right Now
Don't let stick drift ruin your game. Use our visualizer to see if your analog sticks are sending ghost inputs. Stick drift occurs when your character moves on their own, usually caused by:
- Wear and tear: Internal sensors wear out after heavy use.
- Dust & Debris: Dirt interferes with signal readings.
- Physical Damage: Dropping the controller misaligns parts.
- Calibration Errors: The center point software is miscalibrated.
Detected Drift? Here is How to Fix
If our tool confirms faults, don't panic. You can often fix stick drift by cleaning the sensor or adjusting the deadzone. For permanent fixes, consider upgrading to a hall effect ps5 controller which uses magnets to prevent wear.
Works with PS5, PS4 & PS3
Whether you need to test joystick online for a PS4 controller or check an old PS3 gamepad, our input delay tester supports all standard Gamepad APIs.
Controller Diagnostics & Repair Advice
Diagnose Faulty Buttons
Sticky or unresponsive buttons can ruin gameplay. Our tester helps identify which specific buttons aren't working, whether it's a hardware issue or dirt buildup requiring cleaning.
Xbox 360 & Series X Support
Even legacy hardware like the xbox 360 controller is supported. Use this tool to verify used controllers before you buy.
Verify Controller Connectivity
Having connection issues? Test if your controller is actually detected by your device. Useful for troubleshooting Bluetooth pairing problems or USB connection issues.
Calibration Verification
After calibrating your controller or cleaning joysticks, verify the fix worked. Our real-time analog display shows exact stick positions.
Frequently Asked Questions
How do I fix stick drift without taking my controller apart?
Before opening your hardware, try software solutions first. Calibrate your thumbsticks via Windows Game Controllers settings or increase the deadzone in your game's menu to ignore small movements. You can also use compressed air to clear debris from the potentiometer sensor housing, which is a common cause of stick drift in DualSense and Xbox controllers.
How do I test my Xbox Controller on PC?
It's simple to test your Xbox Series X or Xbox One controller on Windows. Connect via USB-C for the lowest latency or use Bluetooth for wireless testing. Our tool uses the browser's Gamepad API to instantly recognize inputs without installing drivers. This is the fastest way to verify button response and check for faults before buying a used Xbox controller.
Why is my Xbox controller drifting?
Most Xbox controllers use ALPS potentiometers that degrade over time due to friction. If our stick drift test shows the red dot moving on its own, the internal wiper tracks are likely worn. While cleaning offers a temporary fix, the only permanent solution for severe drift is soldering a new module or upgrading to a Hall Effect controller which uses magnetic sensors.
Can I test controller vibration on this site?
Yes, our tool fully supports controller vibration testing directly in your browser. We can trigger both the weak (high-frequency) and strong (low-frequency) rumble motors found in PS5, PS4, and Xbox gamepads. Note that vibration support depends on your OS and browser; it works best on Chrome and Edge for Windows and Android.
What is a good polling rate for gaming?
For casual console gaming, a polling rate of 125Hz (8ms delay) is standard. However, competitive PC gamers often overclock their controllers to 1000Hz (1ms delay) to minimize input lag. Our tool measures your real-time Hz so you can verify if your overclocking software (like DS4Windows) is actually working.
How do I know if my controller has stick drift?
To diagnose this, run the test above and leave your thumbsticks perfectly centered. Watch the "Axis" values. If they fluctuate (e.g., jumping between -0.05 and 0.05) or the visualizer jitters without you touching it, you have stick drift. This confirms your analog stick sensors are sending "ghost inputs" to the console.
