Stick Drift Test: Is Your Controller Drifting?

How to run the drift check

1. Connect the controller by USB or Bluetooth and press any button. Browsers only reveal a controller after a press.
2. Put the controller down on a flat surface, or hold it without touching the sticks. Do not rest a thumb on them.
3. Press Start drift check. A progress bar fills over 5 seconds while the tool measures.
4. Read the result for each stick. It shows a verdict, the average offset and the maximum offset.
5. Run it two or three times. Do the check with the controller in the position you normally play, since a stick can read differently when the controller is held.

If the controller does not appear, follow the steps on the controller test page. They cover cables, Bluetooth pairing and remapping software that can hide a pad.

What stick drift is and how the numbers work

Stick drift is when a stick reports movement while nobody is touching it. In a game, the camera creeps, the character walks, or a menu cursor slides.

Each stick has two axes, X and Y, and each reports a value from -1 to 1, where 0 is center. The tool combines them into one offset: the distance from center on a 0 to 1 scale. A stick at rest should read close to 0.

The check samples the offset for 5 seconds and reports two numbers per stick. The average offset shows a steady lean to one side. The max offset shows the largest single reading, which catches jumps and flicker. The verdict uses the average.

The deadzone is the small area around center that a game ignores. This page's slider defaults to 0.10, and many games use their own value. If your drift is smaller than the game's deadzone, you never notice it.

What the verdicts mean

• No drift detected: the average offset is under 0.05. The stick rests close to center.
• Slight drift: the average offset is from 0.05 to 0.10. A deadzone in the game settings usually hides it.
• Stick drift likely: the average offset is over 0.10. The stick reports input that a normal deadzone may not cover, and you will probably notice it in games.

A high max offset with a low average usually means the stick flicks occasionally, for example from a loose connection or a single piece of debris. Run the check again and see whether the result repeats. A controller that is not standard-mapped is checked axis by axis instead of per stick.

What causes stick drift

• Worn potentiometers: most sticks read position with small potentiometers whose contact surfaces wear down with use, so the center reading shifts.
• Dust and debris: dirt or sticky residue under the stick can hold it slightly off center or disturb the sensor.
• Damage: drops, a bent stick shaft, or a stretched spring can leave the stick resting off center.

Sticks that use Hall-effect or TMR sensors resist drift because they read position without a rubbing contact. They are common in aftermarket and replacement modules, but they are not a guarantee against every fault.

How to fix stick drift

Try these in order, from the cheapest to the most involved.

1. Raise the in-game deadzone. Most games let you set an inner deadzone for each stick. Raise it until the drift stops. This hides the problem rather than fixing it, and a very high value makes small movements less precise.
2. Recalibrate. On Windows, a DirectInput pad can be calibrated in "Set up USB game controllers": press Win+R, type joy.cpl, select the controller, open Properties and use the calibration option in the Settings tab. For an Xbox controller, update its firmware in the Xbox Accessories app. For a PlayStation controller, update the firmware through the console or the PC app.
3. Clean around the stick base. Turn the controller off, and clear dust from the gap around the stick with compressed air. Do not pour liquid into the controller.
4. Use warranty, repair or replacement. If the drift stays above 0.10, check whether the controller is still under warranty. Otherwise, a repair shop can replace the stick, or you can buy a replacement stick module if your model has them.

After each step, run the drift check again to confirm the change helped. Before spending money, compare the result on a second port or cable using the full controller test, since a poor connection can look like drift.

Brand-specific notes: Xbox controllers and PS5 DualSense controllers each have their own page.

What this test cannot tell you

The drift check measures the stick at rest. A stick can also behave badly only in motion, such as an uneven or flat-sided circle, so use the Circularity test for that. A browser also cannot tell you why a stick drifts. It reports the numbers and a verdict, and the causes above are the likely explanation.
