Controller Drift Test

How to use

1. Connect the controller. Plug in over USB or pair over Bluetooth, then press any button. The browser only wakes the gamepad once it sends input, and the test panel appears.
2. Let the sticks rest. Take your thumbs off both sticks. Each one shows as a dot that should sit dead center inside the dashed ring. A dot resting outside the ring is drift.
3. Run the measurement. Release the sticks and triggers, press Measure drift, and keep your hands off for three seconds. It records the largest deviation and calls OK or DRIFT for each stick and trigger.

Why test this

Stick drift is the most common way a controller dies. An analog stick starts reporting movement you never made, so your aim creeps, the camera spins, or your character strolls into a wall on its own. It sets in slowly as the potentiometers inside the stick wear down or collect dust, so people blame the game, the sensitivity, or themselves before they suspect the hardware. A test ends the guessing. Instead of a hunch, you let the sticks rest and watch where they sit and how far they drift, then read that against the deadzone a healthy stick stays inside. It also settles whether a pad is worth keeping. A clear drift reading backs a warranty claim or a repair, while a clean one sends you back to in-game sensitivity and deadzone settings. Run it on a controller you suspect, a used one before you pay, or a new one out of the box.

What the results mean

Each stick is drawn as a dot inside a circle, and the dashed ring marks the resting deadzone. At rest the dot should sit on center, inside the ring, with the live X and Y values near zero. Run a measurement and the test watches both sticks and both analog triggers for three seconds, recording the largest deviation each one reaches while idle. Inside the deadzone reads OK. Pushing past it reads DRIFT, and the dot turns red the instant it leaves the ring. Small non-zero numbers are fine. No stick reads a perfect zero, and most pads carry a built-in deadzone of a few percent. What matters is whether the resting value stays small or keeps climbing. A stick that wanders well outside the ring on its own, or a trigger reporting pressure you aren't applying, has worn hardware. Run it twice to be sure the result holds and isn't a one-off twitch.

FAQ

What is stick drift?

Stick drift is when an analog stick reports movement while you aren't touching it. Worn potentiometers or trapped dust make the stick read a position other than center at rest, so your aim or camera slides on its own.

How does this test detect drift?

Let go of the sticks and run a three-second measurement. It records how far each stick wanders from center while idle. Past a normal resting deadzone it reports DRIFT. A healthy stick holds inside the dashed ring.

Does it work with Xbox, PlayStation, and Switch controllers?

Yes. It uses the browser Gamepad API, which reads Xbox, DualShock and DualSense, Switch Pro, and most USB or Bluetooth pads. Press a button after connecting so the browser registers the device.

My controller isn't showing up. What do I do?

Press any button on the pad after you connect it. Browsers only expose a controller once it sends input. Use a Chromium browser for the widest support, and plug in directly rather than through an unpowered hub.

Can this test fix stick drift?

No. It tells you whether drift is there and how bad, nothing more. Fixing it means cleaning the stick module with contact cleaner, recalibrating, or swapping the stick. A clear DRIFT reading points at the hardware, not your settings.

Is the controller drift test free?

Yes. It runs entirely in your browser, needs no install or account, and saves nothing about your controller.
