Gamepad Vibration Test — Controller Rumble Test

Q: How to force a controller to vibrate?

You can force a vibration by sending a playEffect command through the Gamepad API. Our tool does this automatically when you click the Start button, allowing you to bypass in-game settings and test the hardware directly at maximum intensity (1.0000).

Detect dead motors in 30 seconds. Plug in your controller to pinpoint exactly which actuator is failing. Unlike basic checkers, our tool reports numeric intensity values to 4 decimal places for surgical precision.

Whether you're diagnosing a PS5 DualSense, Xbox Series X, or DualShock 4, this controller rumble test analyzes the Gamepad API signals to confirm if the issue is hardware-bound or a browser limitation.

No installation required. Results are instant.

How to Test Controller Rumble

01. Connect

Plug via USB or pair via Bluetooth. Chrome/Edge will detect the device in the HUD above.

02. Focus

Click anywhere on this page. Browsers block the Gamepad API until the user interacts.

03. Start Test

Press Quick Pulse or Stress Test. The tool fires motors in precise sequences.

04. Read Values

Monitor the numeric intensity (0.0000 to 1.0000). Steady zero means a dead motor.

05. Troubleshoot

If values are lower on Bluetooth, it's power-saving. If zero on USB, it's hardware failure.

Vibration Test Troubleshooting

Symptom	Possible Cause	Fix / Action
No vibration at all	Browser Focus or Page Focus	Switch to Chrome/Edge. Click anywhere on the page to "wake up" the Gamepad API.
DualSense Haptics not working	Bluetooth or Audio Mode conflict	Use a USB cable. On PC, full haptic feedback often requires a wired connection or DS4Windows.
One motor reads zero	Internal Hardware Failure	Check connections. If the software sends a signal but the motor stays dead, it needs replacement.
Both motors weak	Low Battery Throttling	Charge your controller. Most controllers reduce rumble power below 15% battery to save energy.
Vibration stops mid-test	Tab Inactivity / Security	Keep the tab active. Browsers pause vibration if you switch tabs or minimize the window.
Xbox triggers silent	API Standard Limitation	Standard browsers only support the main handle motors, not the Impulse Triggers.
Motor will not stop	Firmware / Driver Logic Hang	Disconnect/Reconnect. If it persists, use the reset pinhole on the back of the controller.
Grinding or Clicking	Mechanical Damage	STOP TESTING IMMEDIATELY. The internal weight is loose or the motor shaft is bent.

Key Features

Dual Motor Isolation

Test the high-frequency and low-frequency motors independently. Pinpoint exactly which motor is underperforming without guesswork.

Numeric Intensity Output

Both motors report values in real time to 4 decimal places. No vague “working” or “not working” - you see exact output.

Browser Limitation Detection

The tool flags when your browser is limiting vibration output, so you know immediately whether it is a hardware fault or a restriction.

Full Controller Coverage

Tested with PS5, PS4, Xbox Series X, Switch Pro, and generic USB controllers. If the Gamepad API detects it - this tool tests it.

Zero Setup

Open the page in Chrome or Edge, connect your controller, and press a button - done. No install, no account required.

Wireless vs Wired Comparison

Run tests over USB vs Bluetooth. If wireless is weaker, it is power-saving behavior — not a mechanical motor failure.

Browser Compatibility — Vibration API Support

Browser	Support Status	Notes
Chrome	✅ Full	Recommended - best performance
Edge	✅ Full	Same behavior as Chrome
Firefox	⚠️ Partial	Works on Windows - unreliable on macOS
Safari	❌ None	Vibration API not implemented.
Android Chrome	✅ Full	Full mobile support
iOS Safari	❌ None	No Gamepad API vibration support.

🧭

Safari users: This test will not run on your current browser. Please open this page in Chrome or Edge on any OS. This is the only solution — there is no Safari workaround.

Who Should Use This Tool

Gamers

Pinpoint exactly why your rumble feels mushy or weak. This test confirms if your motor is physically dying or just being throttled by software settings via our Online Gamepad Tester.

Developers and QA

Verify vibrationActuator implementation across different environments. Validate that your code's intensity parameters match the actual hardware output.

Second Hand Buyers

Unlike simple button checkers, this tool reveals hidden motor defects. Use our Full Controller Diagnostic to ensure there is no shattered weighted mass inside.

Parents

Checking a gift for your kids? Verify the hardware works perfectly before they start playing. Ensure the controller is fully functional and worth the price paid.

Tournament Organizers

Verify equipment integrity before a match. Ensure every player has a consistent haptic experience and identify failing hardware before it affects results.

Why This Vibration Test Over Others?

UNLIKE GENERIC CHECKERS

Scientific Numeric Precision

Most sites just offer a vibrate button. We report real time intensity values to 4 decimal places. This allows you to detect if a motor is underperforming by using our Gamepad Health Checker methodology.

HARDWARE VS BROWSER

Isolation Diagnostic Logic

Is the rumble weak because of the controller or the OS? Our tool tests Left and Right actuators independently to identify if a specific internal coil is burnt out.

PRO LEVEL TESTING

Custom Frequency Sequences

Standard tests only fire a single pulse. We provide Frequency Sweeps and Stress Tests to check for intermittent failures where vibration cuts out during sustained gameplay on our Free Gamepad Tester.

PRIVACY FIRST

Zero Data Footprint

The code runs entirely on your local machine via the browser. No account required and no data is sent to a server. Your hardware ID remains 100% private.

Common Real-World Scenarios

"My controller vibrates weakly in Warzone. Is it a dead motor or just low battery?"

"Verifying vibrationActuator fires correctly in Chrome for my new web game."

"Checking both motors of this used PS4 controller before the return window closes."

"Xbox trigger vibration stopped working. Is this a hardware fault or browser limitation?"

Frequently Asked Questions

How to check if a controller has vibration?

Most modern controllers (Xbox, PlayStation, Switch) have internal motors. To check, connect your device to this tool and press "Start Test." If you feel a physical rumble or see numeric values move on the screen, your controller has functional vibration actuators.

How to test vibration on Switch controllers?

Connect your Joy-Cons or Pro Controller via Bluetooth or USB. Note that Nintendo uses "HD Rumble" (LRA motors). While the browser Gamepad API supports basic vibration for Switch, the intensity might feel different than on the console. Use our tool to confirm both left and right motors respond to signals.

How to force a controller to vibrate?

You can force a vibration by sending a "playEffect" command through the Gamepad API. Our tool does this automatically when you click the Start button, allowing you to bypass in-game settings and test the hardware directly at maximum intensity (1.0000).

How do I check if my controller buttons are working?

Vibration is only half the story. To check buttons, triggers, and bumpers, you should use our dedicated Button Tester. If a button feels "mushy" or doesn't register a 1.0 value when pressed, the internal rubber membrane or microswitch might be worn out.

Why does my PS5 DualSense have weak vibration?

DualSense uses voice-coil actuators. Browsers send simplified signals rather than full waveform data. This is a normal software limitation of the Gamepad API, not a sign of a broken controller.

Why does my Xbox controller not trigger vibration?

Xbox trigger motors are separate from handle motors. Current web standards only support the main handle vibration. Trigger "Impulse" haptics currently require native Windows apps or specific game support.
