Reports are stored in this browser. Sharing is optional and puts only the selected result in the link.
Diagnostic readings describe what this browser receives, not electrical measurements from the controller. Confirm important findings in the game or device where you plan to use the controller.
Use the test as evidence, not a pass/fail sticker.
Stick drift happens when a controller reports movement even though you are not touching the analog stick. This test displays the live X and Y values your browser receives, then measures how far each stick wanders from its resting center.
For the most useful result, place the controller on a stable surface and leave both sticks untouched during the hands-off sample. You can then move each stick through its full range to compare the resting result with normal input.
The reading reflects the controller data exposed by your operating system and browser. It is a strong troubleshooting signal, but it is not a factory calibration certificate or a measurement of in-game behavior.

Run a repeatable check.
- 01
Connect the controller and press any button so the browser can detect it.
- 02
Use the focused test panel slowly and deliberately. Watch the live values during presses, holds, movement, and release.
- 03
Repeat any suspicious result after reconnecting, then confirm it in the game or device where the controller will be used.
What a useful result looks like.
Look for repeatable behavior rather than a single momentary value. Stable, symmetric movement and clean press-and-release behavior are generally more useful signs than chasing a perfect zero.
If a result changes substantially between USB and wireless modes, browsers, or computers, the connection, driver, browser, or remapping software may be part of the problem.
Important browser-test limits
Do not touch the sticks during the hands-off sample.
Questions about analog stick drift test
What stick drift value is considered bad?
There is no universal cutoff because games apply different deadzones. A steady center offset above a game's deadzone can create unwanted movement. Compare the measured offset with the deadzone options in the game you play.
Why does the value move slightly near zero?
Small fluctuations can come from sensor noise, wear, wireless conditions, or operating-system processing. A tiny, random movement that stays inside the game's deadzone may not be noticeable during play.
Can this website repair stick drift?
No. The tool can document symptoms and help you compare results. Cleaning, recalibration, parts replacement, or manufacturer service may be needed depending on the cause.
