Stick drift test
Let both sticks rest, then compare live axis values with an adjustable dead zone.
Last updated: July 29, 2026
Stick drift test: This stick drift test focuses on resting analog-stick axes and compares them with a dead zone you choose.
How this stick drift test works
Connect the controller, press a button, release both sticks, and wait for the values to settle. Compare several dead-zone settings, then rotate each stick fully and reset the maximum before another resting sample.
How to read the results
Axis values near zero are centered. A small nonzero value can be normal, while repeatable resting movement outside a game's dead zone can move the camera or character. The practical threshold depends on the controller and game.
Common causes of failed tests
Drift can come from worn potentiometers, contamination, spring wear, calibration, firmware, Hall sensor alignment, wireless interruption, or remapping software.
Troubleshooting before you replace hardware
Update official firmware, remove remapping, reconnect by USB, recalibrate only through official tools, and compare the full gamepad tester. Hardware service may be needed when drift is repeatable across devices.
For setup and buying context, see the gamepad tester and mouse test.
Frequently asked questions
How much stick drift is normal?
Tiny resting values can be normal; repeatable movement outside a game's dead zone is the practical problem.
Does this change controller dead zones?
No. It compares live axes with a selected threshold but does not change firmware or game settings.
Why must I press a button first?
Browsers commonly require interaction before exposing a connected gamepad.
