Controller Drift Test
Put your controller down, keep your hands off, and get a drift verdict in 10 seconds.
- 1. Connect & press any button
- 2. Put the controller down
- 3. Hands off for 10 seconds
Waiting for a controller — press any button to wake it.

How it works
Stick drift means your controller reports movement when nobody is touching it. This test samples both analog sticks on every animation frame for ten full seconds while the controller sits untouched, then computes the mean radial deviation from perfect center. Using the mean rather than the peak means a bumped desk won't fail a healthy controller — only a sustained off-center signal registers as drift.
Deviation under 2% is normal electrical noise and reported as no drift. 2–5% is mild drift that game deadzones usually hide. 5–10% is moderate — you'll notice slow camera creep in games with tight deadzones. Above 10% is severe and the stick module needs cleaning, recalibration or replacement. Quick workarounds while you decide: raise the in-game deadzone slider; on PS5, update the controller firmware via Settings → Accessories; on Switch, run Calibrate Control Sticks in System Settings; on Xbox and PC, compressed air around the stick base clears debris-caused drift surprisingly often. For a full walkthrough, read our guide to fixing controller drift.
What your drift percentage means
Stick drift is when an analog stick reports movement while you are not touching it. This test samples both sticks every frame for 10 seconds with your hands off, then reports the sustained deviation from dead center as a percentage. A small number is normal electrical noise; a large, steady one is a worn potentiometer or Hall sensor.
Reading the deviation %
| Deviation | Verdict | In-game effect |
|---|---|---|
| Under 2% | Healthy | Invisible — normal sensor noise |
| 2–5% | Mild drift | Usually hidden by the game's deadzone |
| 5–10% | Noticeable | Slow camera/character creep in some games |
| Over 10% | Failing | Constant unwanted movement — needs service |
Before you conclude it's broken
- Rest the controller on a stable surface — desk vibration and a taut charging cable both nudge readings.
- Run it two or three times; a one-off spike is not drift.
- Fully seat the stick — a stick still returning to center after you let go can read high on the first second.
Fixes, from easiest to last resort
- Recalibrate where the platform allows it (Steam, Windows "Set up USB game controllers", DualSense/Switch built-in tools).
- Clean around the stick base with compressed air, then a little isopropyl alcohol worked in by moving the stick.
- Raise the in-game deadzone to mask mild drift while you decide on a repair.
- Replace the stick module — worn potentiometer sticks eventually need new hardware; Hall-effect replacement modules resist drift long-term.
Troubleshooting
› The test says drift but my sticks feel fine in games
Games apply a deadzone that hides small drift. Deviation under about 5% is usually invisible in play; above 10% you will start to see slow camera or character movement.
› The result changes between runs
Make sure the controller rests on a stable surface with nothing touching the sticks, and that no cable is pulling on it. Vibration from the desk or a charging cable can nudge readings.
› My controller isn’t detected at all
Press any button once — browsers hide controllers until first input. Then start the test and let go. If it still fails, test the pad on the gamepad tester first.
Frequently asked questions
› How does the drift test work?
You leave the controller untouched for 10 seconds while we sample both sticks every frame. Sustained deviation from center is reported as drift with a severity percentage.
› What percentage of drift is bad?
Under 2% is normal sensor noise. 2–5% is mild and usually masked by game deadzones. Above 5% you will likely notice unwanted movement, and above 10% the stick needs service.
› Can drift be fixed?
Sometimes. Recalibrating (where the platform supports it), cleaning around the stick base, or raising the in-game deadzone all help. Worn potentiometer sticks ultimately need module replacement.
› Does this work for PS5, Xbox and Switch controllers?
Yes — any controller your browser detects can be tested, including DualSense, Xbox Series, Switch Pro and Joy-Cons (connected via Bluetooth).
