Gamepad Stick Drift Test — Check Your Controller

How to use

1. Connect your controller. Plug in over USB or pair over Bluetooth, then press any button so the browser wakes the gamepad and the test panel appears.
2. Watch the sticks at rest. Let go of both sticks. Each one is shown as a dot. At rest it should sit on the center inside the dashed ring. A dot resting outside the ring is drift.
3. Run a drift measurement. Release the sticks and triggers, press Measure drift, and keep your hands off for three seconds. The test records the largest deviation and shows an OK or DRIFT verdict per stick and trigger.

Why test this

Stick drift is the most common way a controller dies: the analog stick starts reporting movement you never made, so your aim creeps, the camera spins, or your character walks into a wall on its own. It creeps in gradually as the potentiometers inside the stick wear or pick up dust, which makes it easy to blame your game, your settings, or yourself long before you realize the hardware is at fault. Testing puts a number on it. Instead of a vague feeling that something is off, you can release the sticks and watch exactly where they rest and how far they wander, then compare that against the deadzone a healthy stick stays within. It is also the fast way to decide whether a controller is still worth keeping: a clear drift reading is grounds for a warranty claim or repair, while a clean result points you back to in-game sensitivity or deadzone settings. Run it on a controller you suspect, a used one before you buy, or a new one straight out of the box to confirm it is sound.

What the results mean

Each stick is drawn as a dot inside a circle, with a dashed ring marking the resting deadzone. At rest the dot should sit on the center, inside the ring, and the live X and Y values should read close to zero. When you run a measurement the test watches both sticks and both analog triggers for three seconds and records the largest deviation each one reaches while idle. A reading inside the deadzone shows OK; one that pushes past it shows DRIFT, and the dot turns red the moment it leaves the ring. Small non-zero numbers are normal. No stick reports a perfect zero, and most controllers have 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 that reports pressure you aren't applying, has worn hardware. Run the measurement a couple of times to be sure the result is consistent rather than a one-off twitch.

FAQ

What is stick drift?

Stick drift is when a controller registers movement on an analog stick even though you aren't touching it. Worn potentiometers or dust let the stick report a non-zero position at rest, so your character or camera moves on its own.

How does this test detect drift?

Release the sticks and run a three-second measurement. The test records the largest distance each stick wanders from center while idle. If that exceeds a normal resting deadzone it reports DRIFT; a healthy stick stays inside the dashed ring.

Does it work with Xbox, PlayStation and other controllers?

Yes. It uses the browser Gamepad API, which supports Xbox, DualShock/DualSense, Switch Pro and most USB or Bluetooth controllers. 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 gamepad after connecting; browsers only expose it once it sends input. Use a Chromium-based browser for the widest support, and check that the controller is paired or plugged in directly rather than through an unpowered hub.

Can this test fix stick drift?

No. It only diagnoses whether drift is present and how severe it is. Fixing it means cleaning the stick module with contact cleaner, recalibrating, or replacing the stick. A clear DRIFT reading tells you the hardware, not your settings, is the problem.

Is the gamepad drift test free?

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