Nintendo Switch Drift Test

How to use

1. Pair the controller to a phone or PC. The Switch can't open a browser, so connect the Joy-Con or Pro Controller over Bluetooth. Each Joy-Con pairs on its own, so add the left and the right separately.
2. Rest the sticks. Let go of both sticks. A dot marks each Joy-Con, and a healthy one parks dead center in the ring the second you let go. If a dot won't settle inside the ring, that Joy-Con is drifting.
3. Run the drift check. Let go, then hit Measure drift and stay off both sticks for three seconds. The tester logs the worst deviation for each one and posts an OK or DRIFT call the moment the timer ends.

Why test this

Your character wanders while both thumbs are off the sticks. A menu scrolls on its own, or your aim pulls to one edge. Joy-Con drift is the most common way a Switch controller fails, and it turned up often enough that Nintendo ran a free repair program for it. The cause is the small potentiometer stick inside each Joy-Con. A graphite pad wears, dust gets in, and the stick starts reporting motion at rest. A test tells you which stick is going and how far. Because the Switch can't run a browser, you connect the Joy-Con or Pro Controller to a phone or PC over Bluetooth and read the sticks there. This test catches a stick a few percent past its resting deadzone, well before the drift is big enough to notice mid-game. That reading is also your evidence if you go after Nintendo's repair program instead of guessing at the cause.

What the results mean

Each Joy-Con stick draws a dot inside a dashed ring, with live X and Y numbers beside it that should sit close to zero the moment you let go. Press Measure drift and stay off the sticks for three seconds. The tester tracks how far each dot strays from center. It reads OK while the dot stays inside the ring, DRIFT the instant it crosses out, and the dot turns red right then. A resting reading within a few percent of center is normal noise, not drift. The problem is a dot that keeps sliding further out, or one that never settles back to zero between runs. Recalibrating in the Switch's Calibrate Control Sticks menu can shrink a small drift by moving where center sits, but it can't stop a worn potentiometer from drifting right back once the contacts wear more. If one Joy-Con keeps failing after that, send in or repair that one, not the pair.

FAQ

Can I test Joy-Con drift on the Switch itself?

No. The Switch has no browser, so you pair the Joy-Con to a phone or PC over Bluetooth and test there. Its Calibrate Control Sticks screen only re-centers the reading. It doesn't detect wear the way this does.

Why does only one Joy-Con show up?

Each Joy-Con connects as its own gamepad. Pair the left and the right one at a time, run the test on each, and you learn exactly which stick is drifting.

Does Nintendo fix Joy-Con drift for free?

Nintendo has repaired drifting Joy-Con at no charge in several regions, in some cases even out of warranty. A clear DRIFT reading from a test is the proof to attach when you open a repair request.

Does the Switch calibration menu fix drift?

It can mask light drift by resetting where center sits, but it doesn't repair a worn potentiometer. If the stick keeps drifting after you recalibrate, the hardware needs cleaning or a replacement.

Do Switch Pro Controllers drift too?

Yes. The Pro Controller uses the same potentiometer stick design as the Joy-Con, so it wears the same way. Test it over Bluetooth exactly like a Joy-Con.

Is the Joy-Con drift test free?

Yes. Open the test page on whatever you paired the Joy-Con to. No install, no account, and no Nintendo Switch Online login needed.
