Set the controller on a flat surface and don't touch it during the test.

This is normal sensor noise. Every analog stick reports tiny values at rest, and game deadzones absorb them completely. No action needed.
Above typical factory tolerance but still inside most default deadzones. Try recalibration first — on PlayStation controllers our calibration tool can often reset this to zero.
Your character or camera will visibly move on its own. Calibration may help temporarily, but sustained drift at this level usually means the stick module needs replacement.
Most analog sticks use potentiometers — tiny carbon tracks that a wiper slides across as you move the stick. Over hundreds of hours of play, the carbon wears away and the wiper starts reporting positions that don't match where the stick physically sits. Dust, sweat, and worn centering springs make it worse. That's why drift almost always develops gradually: a hair of camera pull at first, then a character who walks by themselves.
Drift affects every brand. Joy-Cons are the most notorious, but DualSense, DualShock 4, and Xbox controllers all use similar ALPS-style potentiometer sticks with a typical rated life of roughly 2 million cycles — heavy players hit that in under a year.
While your sticks rest untouched, the test samples their reported position dozens of times per second for 10 seconds via the browser's Gamepad API. It then computes the average and maximum deviation from true center for each stick and traces every sample on the circle so you can literally see the wander. A healthy stick draws a dot; a drifting stick draws a smear.
If your PlayStation controller failed the test, start with our free PS controller calibration tool — it rewrites the center point stored in the controller's own firmware, which cures mild drift without opening anything. Xbox owners can recalibrate through the Xbox Accessories app's deadzone settings, and Switch owners through System Settings → Controllers.
When drift returns after calibration — or the deviation is far past 0.10 — the potentiometer itself is worn and no software can fix it. Phone Repair & More replaces stick modules on PS5, PS4, Xbox, and Switch controllers at all 9 Florida locations, typically same-day, with a free diagnostic first and a 90-day written warranty. You can also check the rest of your controller with the full controller tester.
No — once the potentiometer track is worn, drift only progresses. Cleaning around the stick base with isopropyl alcohol or compressed air can temporarily improve contact, and calibration can re-zero mild drift, but worn hardware eventually needs a new stick module.
Early-stage wear is temperature- and position-sensitive: the wiper still makes good contact most of the time. Intermittent drift is the best moment to calibrate, before wear becomes constant.
It hides drift rather than fixing it, and it costs you precision — small aiming movements inside the enlarged deadzone are ignored. It's a reasonable stopgap, not a repair.
The browser reads the same raw axis values your PC games receive, so resting deviation is measured exactly. Console-side behavior can differ slightly if the console applies its own deadzone, but the hardware measurement itself is accurate.
It varies by controller model and whether one or both sticks are worn. Phone Repair & More diagnoses your controller free of charge and quotes the exact price before any work starts — you only pay if you approve.
Our technicians replace worn stick modules on PlayStation, Xbox, and Switch controllers — usually same-day. Free diagnostic, honest quote, 90-day warranty.
