Free PS5 Controller DualSense Test
The TechTester PS5 DualSense controller test lets you check every single input on your PlayStation 5 controller directly in your browser no app download, no PlayStation console required, no account needed. Connect your DualSense via USB-C cable or Bluetooth, open this page, press any button, and every input will appear on screen in real time. Test all face buttons, shoulder buttons, adaptive triggers, thumbsticks, the D-pad, touchpad, Create button, Options button, and the PlayStation button. Instantly identify which inputs are working correctly and which are faulty including thumbstick drift, trigger calibration issues, and unresponsive buttons.
How to connect your PS5 DualSense to PC for testing
The PS5 DualSense controller can connect to your PC in two ways USB-C cable (recommended for testing) or Bluetooth. Follow these steps:
USB-C connection (recommended)
- Get a USB-C to USB-A cable the same type used for many Android phones and accessories
- Plug the USB-C end into the port at the top of your DualSense controller
- Plug the USB-A end into any USB port on your PC or laptop
- The controller will power on automatically the light bar will glow
- Open this page in Chrome or Edge and press any button to activate detection
USB-C is the most reliable connection method for testing. It gives a direct, low-latency connection and charges the controller at the same time.
Bluetooth connection
- On your PC, open Settings → Bluetooth & devices → Add device → Bluetooth
- Hold the Create button and the PlayStation button on the DualSense simultaneously
- Hold both until the light bar flashes white rapidly the controller is now in pairing mode
- Select DualSense Wireless Controller from the Bluetooth device list on your PC
- Once paired, the light bar glows steady blue the controller is connected
- Open this page in Chrome or Edge and press any button to begin testing
How to test your PS5 DualSense
Step 1 – Activate the controller on screen
With your DualSense connected, open this page and press any button once. The controller will appear in the detected gamepad list on screen. You will see a visual representation of the DualSense with all inputs mapped face buttons, shoulder buttons, triggers, thumbsticks, D-pad, and special buttons.
Step 2 – Test all face buttons
Press Cross (X), Circle (O), Square, and Triangle one at a time. Each button should light up on the display immediately when pressed and return to its default state when released. If any button shows a delay, fails to appear, or stays lit after you release it, that button has a fault.
Step 3 – Test shoulder buttons and adaptive triggers
Press L1 and R1 these are the shoulder bumper buttons above the triggers. They should register as a binary press (on/off). Then pull L2 and R2 the adaptive triggers. These are analog inputs. Watch the trigger axis value: it should go from 0.00 at rest to 1.00 at full press, smoothly and consistently. If either trigger shows a non zero value at rest, sticks at a partial value, or does not reach 1.00 at full pull, the trigger mechanism is faulty.
Step 4 Test thumbsticks and check for drift
Move the left thumbstick in all directions up, down, left, right, and all four diagonals. Do the same for the right thumbstick. Both sticks should show smooth, proportional axis values as you move them. Then fully release both sticks and do not touch them. Watch the axis readings for Left Stick X, Left Stick Y, Right Stick X, and Right Stick Y. In a healthy DualSense, all four readings will settle at or very close to 0.00. If any axis reads above 0.05 consistently while the stick is at rest, your controller has thumbstick drift.
Step 5 – Test D-pad, touchpad, and remaining buttons
Press all four D-pad directions individually. Press the touchpad (it is a clickable button, not just a touch surface). Press the Create button (formerly Share), the Options button, the PlayStation button, and both L3 and R3 (thumbstick clicks press straight down on each stick). All inputs should register cleanly.
What your test results mean
0.00 to 0.03 – Healthy
Normal resting variation. No drift. Your thumbstick is working correctly.
0.05 to 0.12 – Mild drift
Visible in precise games. Try cleaning around the stick base with isopropyl alcohol.
Above 0.15 – Significant drift
Will cause visible movement in all games. Controller needs repair or replacement.
Button stuck or registering without pressing
If a button appears lit on the display without you pressing it, that button is stuck internally. This is usually caused by debris inside the controller, a damaged rubber dome, or a faulty switch. Try pressing and releasing the button firmly several times to dislodge debris. If the issue persists, the button mechanism needs repair.
Trigger not reaching 1.00 at full press
If pulling a trigger fully does not reach a value of 1.00 (or very close — 0.95 to 1.00 is normal), the trigger mechanism may be worn, the spring tension may have degraded, or there may be debris limiting the full range of motion. Clean around the trigger hinge area and retest.
How to fix common PS5 DualSense problems
Fix thumbstick drift cleaning method
Power off the controller. Dip a cotton swab in isopropyl alcohol (90% or higher do not use rubbing alcohol below 70%). Gently work the swab around the full circumference of the thumbstick base, rotating the stick slowly while cleaning. Use a second dry swab to remove any excess moisture. Allow to dry for 10 minutes at room temperature. Retest using this page for mild drift (readings below 0.10), this method resolves the issue in a significant proportion of cases.
Reset the DualSense controller
There is a small reset button in a pinhole on the back of the DualSense, near the L2 trigger. Use a pin or paperclip to press and hold it for 5 seconds with the controller powered off. Reconnect via USB-C and press the PlayStation button. Retest all inputs on this page. This resolves calibration drift that is software rather than hardware in origin.
Update DualSense firmware
Sony periodically releases DualSense firmware updates that include thumbstick calibration improvements. Connect your DualSense to a PS5 console via USB-C and go to Settings → Accessories → Controllers → Update. Alternatively, firmware can be updated through Sony’s PC firmware updater tool (available from the PlayStation website).
Sony warranty claim
PS5 DualSense controllers are covered by Sony’s standard 12 month manufacturer warranty. Drift caused by normal use has been accepted as a warranty claim by Sony in most markets. Contact PlayStation Support with your proof of purchase. If your controller is out of warranty, authorised repair centres and third party repair services can replace the thumbstick potentiometers for significantly less than the cost of a new controller.

FAQ
Yes. The TechTester PS5 controller test works by connecting your DualSense to a PC via USB-C cable or Bluetooth. You do not need a PlayStation 5 console to run the test. The Web Gamepad API in your browser detects the DualSense directly.
Connect your DualSense and open this page. Once detected, fully release both thumbsticks and do not touch the controller. Watch the axis value readings. If any axis reads above 0.05 consistently while the stick is at rest, drift is present. Values above 0.15 will cause visible in-game movement.
Cleaning with isopropyl alcohol around the thumbstick base resolves drift in a significant number of cases, particularly when the cause is debris or dust buildup rather than worn potentiometer tracks. Test before and after cleaning using this page to confirm whether the values improve.
Drift can occur on either stick or on both simultaneously. The left stick is statistically more common because it handles forward movement (the most frequently used input in most games). The TechTester test shows separate axis readings for both sticks so you can identify exactly which stick — and which axis (X or Y) — is affected.
Sony’s standard warranty is 12 months from purchase. Drift caused by normal use has been accepted as a warranty repair by Sony in most markets. Contact PlayStation Support with proof of purchase. Consumer protection laws in some countries (including the UK and EU) may extend your rights beyond the 12-month manufacturer warranty.
Yes. Use a USB-C to USB-A cable (most PC users) or USB-C to USB-C (for PCs with USB-C ports). Plug directly into the computer rather than a USB hub for the most reliable connection. Windows will detect the DualSense automatically with no additional drivers needed.
Google Chrome and Microsoft Edge provide the most complete Web Gamepad API support and are recommended. Firefox also works. Safari supports the Gamepad API from version 16.4 onwards. For the most accurate thumbstick readings, use Chrome or Edge.
Yes. The TechTester gamepad checker detects the analog pressure values of L2 and R2. You can see the trigger axis go from 0.00 at rest to 1.00 at full press. However, the DualSense’s adaptive trigger resistance features (variable haptic tension) are a PS5 console feature and cannot be tested via the browser Gamepad API.
