Test Your Controller Connection
Plug in or pair your controller, press any button, and choose a test length. Keep this page active during your session.
DEVICE STATUSWaiting for controller● Not detectedPress a controller button after connecting. Browser support varies.
Idle controllers may stop reporting updated timestamps. Gaps are evaluated only during observed active input; they are not proof of dropped Bluetooth packets.

03 / CONNECTION SETUP
How to Check USB and Bluetooth Controller Stability
Begin with the same controller and game conditions you normally use. Connect your Xbox, PS4, PS5 or compatible PC gamepad with a known working cable or Bluetooth pairing.
- Open this tool in a modern browser and press a controller button.
- Select the connected gamepad and choose a 60-second or longer session.
- Move a stick back and forth and press buttons at a steady pace.
- Watch for genuine disconnects and compare repeated measurements.
Keep the page visible throughout the test. Tab switching and background throttling can distort browser timing. Avoid treating an idle controller as a failed connection.

04 / UNDERSTANDING RESULTS
How to Read Connection Drops and Input Timing Gaps
A disconnect means the selected controller stopped being exposed as connected through the Gamepad API. A longer input interval means the browser observed more time between changed gamepad states.
Neither result on its own identifies radio interference, packet loss, controller firmware, battery condition or USB electrical faults. Active-input intervals can also be affected by browser frame scheduling.
- Repeat the same test with USB and Bluetooth if supported.
- Compare genuine disconnect events rather than relying only on interval spikes.
- Try another USB cable or compatible port when wired disconnections recur.
- Use controller firmware and operating-system diagnostics to investigate recurring problems.

05 / EXPLANATION
What Does a Controller Connection Stability Test Measure?
Connection Visibility
Tracks when a browser can see a selected controller, including genuine connect and disconnect events.
Input State Changes
Records meaningful movement or button changes. Idle controllers can legitimately report no new input.
Browser Update Intervals
Measures gaps between observable input changes. These reflect browser sampling and usage patterns, not physical radio polling.
Session Reliability
Shows how long the device remained exposed while the test was active, excluding periods when the browser tab was hidden.
Wired vs Wireless
Save repeated tests under comparable conditions to identify patterns without claiming lab-grade signal measurements.
Privacy and Export
Reports are generated in your browser. Export JSON or CSV to retain a personal record of the test results.
06 / TROUBLESHOOTING
Fix Frequent Controller Connection Issues
Controller not detected
Press any controller button while the page is visible. Confirm USB data support, system pairing and browser Gamepad API access.
Bluetooth disconnections
Compare results with a wired connection, check controller charge and make sure the device is paired correctly in system settings.
Input gaps without disconnects
Keep the page in focus, create steady input and repeat the measurement. Browser timing gaps are not automatically lost packets.
Multiple controllers connected
Select the exact gamepad from the device menu. A different device may take over an index after reconnection.
07 / FAQS
Connection Stability Test FAQs
How do I test a controller connection online?
Connect your controller, press a button so the browser can see it, start monitoring and move the sticks or press buttons regularly while the page remains visible.
Does this test work with Xbox, PS4 and PS5 controllers?
It works with devices that your operating system and browser expose through the Gamepad API, including many Xbox, DualShock 4 and DualSense controllers.
Can this measure Bluetooth packet loss?
No. Browsers do not expose raw Bluetooth radio packet loss through the Gamepad API. The tool records visible connection changes and browser-observed input timing.
Why does the timing graph change when I stop moving?
When a controller is idle, gamepad state timestamps may stop changing. Idle periods are not classified as input gaps by this tool.
Does a large update gap mean my controller is broken?
Not necessarily. Browser scheduling, uneven user movement and system load all affect the time between visible changes.
Can I run the test in the background?
For meaningful results, keep the testing tab visible. Browsers throttle background animation and input polling; the page flags visibility interruptions.
Is USB more stable than Bluetooth?
Wired connections can remove some wireless variables, but actual performance depends on the controller, cable, ports, adapter and environment. Compare repeated sessions on your own setup.
Is the connection stability checker free?
Yes. The tester runs locally in your browser with no account required.
Can I download a report?
Yes. Download JSON or CSV records, copy a summary or store recent comparisons in local browser storage.
Is this an input latency tester?
No. It does not measure the time between a physical button press and the corresponding in-game or on-screen response.
