Controller Stick Drift &
Analog Deadzone Tester
Connect your PS5, Xbox, Switch Pro, or PC controller via USB/Bluetooth to inspect real-time analog stick centering, deadzone thresholds, and circularity.
๐ฎ Controller Connection
CONNECT GAMEPADPress any button on your controller to activate detection (or use the simulated stick controls below).
๐ Hardware Health Diagnosis
Your analog stick shows minimal resting deviation (2%). With a standard 5% in-game deadzone applied, your crosshair will not drift or pan on its own during gameplay.
Frequently Asked Questions
How does the Gamepad Stick Drift Tester work?
This tool connects directly to your controller via the HTML5 Web Gamepad API. It polls analog stick X and Y potentiometer axes up to 250 times per second, measuring resting deviations from true center (0.0000, 0.0000). If your analog stick fails to re-center when untouched, it confirms hardware stick drift.
Why do standard potentiometers get stick drift while Hall Effect sticks do not?
Standard controllers (PS5 DualSense, Xbox Wireless) use carbon resistive wiper potentiometers. As you rotate the stick, metal fingers physically scrape the carbon track, causing friction wear and graphite dust debris that alters electrical resistance within 3 to 12 months. Magnetic Hall Effect sticks use non-contact magnetic flux sensors that never physically touch, completely eliminating mechanical drift wear.
What in-game deadzone should I set if I have slight stick drift?
Check your drift magnitude on this tester (e.g. 0.04 = 4% drift). In games like Apex Legends, Warzone, or Fortnite, set your Controller Inner Deadzone to 5% (just 1% above your resting drift value). This completely prevents unwanted camera panning while preserving maximum aim sensitivity.
