Controller lab
Controller stick drift observation
Record stick-axis values at rest for a chosen period and review the observed peak radius.
How to use this check
Connect a controller, press one of its buttons, then start. Available mappings and features depend on your browser, OS and device.
What the browser measures
Axes 0/1 and 2/3 are shown when exposed. The green circle is your preview threshold, not a hardware diagnosis. Numeric axis values appear above.
Reading the result
Place the controller on a stable surface, release the sticks and record ten seconds. A nonzero value describes the reported position. Compare repeated trials; this site provides no universal acceptable-drift threshold.
Why results can differ
A browser observes events exposed by your operating system. One test cannot establish whether a device is faulty. Connection, settings, focus and browser behavior can change the results.
