- [How to Test Controller Latency: Diagnose the Cause, Then Measure the Number](https://gpadtesterpro.com/how-to-test-controller-latency/): Controller latency is the delay between pressing a button and your system registering it, and it's caused by one of five things: your connection type (wired vs. wireless), wireless interference, outdated firmware, background software intercepting input, or display/game-engine delay unrelated to the controller. Most people can identify the cause in under two minutes using the checklist below, then confirm the exact number with a browser-based latency test.
- [Why Does My Controller Keep Disconnecting? Real Causes & Fixes (2026)](https://gpadtesterpro.com/why-does-my-controller-keep-disconnecting/): If your controller keeps disconnecting, the cause is almost always one of five things: wireless interference on the 2.4GHz band, a weak or corroded battery contact, a faulty USB cable or port, outdated firmware or drivers, or a power-management setting cutting the connection to save energy. Wired controllers point to a cable, port, or driver problem. Wireless and Bluetooth controllers point to interference, range, or battery issues. You don't need to guess which one applies to you, you can test for it directly, and this guide shows you how before you start changing settings at random.
- [How to Connect a PS5 Controller to iPhone](https://gpadtesterpro.com/how-to-connect-a-ps5-controller-to-iphone/): Pairing a PS5 DualSense controller with an iPhone turns touchscreen gaming into something that actually feels like console gaming - real buttons, real sticks, real triggers. Apple builds native support for PlayStation controllers directly into iOS, so no third-party app, jailbreak, or adapter is required. All you need is Bluetooth, or a USB-C cable if both your DualSense and iPhone support it. We tested this pairing process across three iPhone generations and two controller types while preparing this guide, specifically to catch the details most write-ups get wrong or leave out.
- [Why Is My Controller Not Working? A Complete Diagnostic Guide](https://gpadtesterpro.com/why-is-my-controller-not-working/): A controller your device doesn't recognize at all is almost always a cable, port, or pairing problem, not a broken controller. A controller that is recognized but does nothing in-game is usually a software conflict, like another app holding exclusive access. A controller where only specific buttons or sticks fail is the clearest sign of real hardware wear. Identify which of these three you're dealing with before trying any fix, or you'll waste time solving the wrong problem.
- [How to Calibrate Xbox One Controller (Step-by-Step Guide for PC & Console)](https://gpadtesterpro.com/how-to-calibrate-xbox-one-controller/): A well-calibrated controller can completely change how your games feel. If your aim seems off, your character moves without input, or triggers respond unevenly, the issue is often not the game, but your controller calibration. You can also verify these issues using a gamepad testerto quickly detect stick drift or input problems.
- [How to Use a Controller on PC (Complete Setup Guide)](https://gpadtesterpro.com/how-to-use-a-controller-on-pc/): Using a controller on a PC has become extremely common among modern gamers. While keyboard and mouse setups still dominate certain genres, many players prefer the comfort and precision of a controller for specific types of games. Whether you want to play racing games, sports titles, platformers, or simply enjoy a more relaxed gaming experience from your chair or couch, connecting a controller to a PC is easier than ever.
- [How to Fix Stick Drift (Complete Controller Repair Guide)](https://gpadtesterpro.com/how-to-fix-stick-drift/): Stick drift is one of the most frustrating problems gamers experience with modern controllers. When it happens, the analog stick sends movement signals even when you are not touching it. This can cause your character to walk on its own, the camera to slowly rotate, or aim to become inaccurate during gameplay. Many players immediately think their controller is broken, but in many cases the issue can be repaired without replacing the device.
- [How to Connect Xbox Gamepad to PC (Complete Beginner Setup)](https://gpadtesterpro.com/how-to-connect-xbox-gamepad-to-pc/): Connecting an Xbox gamepad to a PC is one of the easiest ways to improve your gaming experience. Many modern PC games are designed with controller support, and Microsoft has made Xbox controllers fully compatible with Windows devices. Whether you want to play racing games, action titles, or sports games, using a controller often feels more natural than a keyboard and mouse.

- [Home](https://gpadtesterpro.com/): A gamepad tester is a browser-based tool that uses the Web Gamepad API to read every input signal from your connected controller in real time, including buttons, analog sticks, triggers, vibration motors, motion sensors, and input latency, without requiring any software installation. Connect via USB or Bluetooth, press any button to wake the controller, and every input appears live on screen.
- [Gamepad Trigger Pressure Test](https://gpadtesterpro.com/gamepad-trigger-pressure-test/): A gamepad trigger pressure test reads the raw analog value your controller's L2/R2 or LT/RT triggers report - on a scale from 0.00 (released) to 1.00 (fully pressed) - so you can see whether the sensor is responding smoothly and reaching full range, independent of how any single game happens to display it.
- [Stick Drift Test](https://gpadtesterpro.com/gamepad-stick-drift-test/): Get quick responses to frequently asked questions regarding Gamepad Stick Drift Test.
- [Gamepad Connection Stability Test](https://gpadtesterpro.com/gamepad-connection-stability-test/): A connection stability test is not the same thing as a latency test, and confusing the two leads people to fix the wrong problem. Latency asks "how long does one input take to arrive?" Stability asks "does the link stay up, consistently, for the entire session?"
- [Gamepad Button Test](https://gpadtesterpro.com/gamepad-button-test/): A controller button tester is a browser-based tool that reads your gamepad's raw input signals through the Gamepad API and shows you, in real time, whether each button registers correctly. Connect your controller via USB or Bluetooth, press any button to wake detection, then press every button on your pad - each one lights up on screen and is logged with a response time and a status flag (OK, STICKY, BOUNCE, or FAIL). Works in Chrome and Edge on Windows, Mac, Android, and Safari on iOS 16.4+.
- [ Gamepad Vibration Test](https://gpadtesterpro.com/gamepad-vibration-test/): A controller vibration test checks whether your gamepad's rumble motors respond correctly by sending vibration commands straight through your browser - no game required. It tells you in under a minute whether a vibration problem is your hardware, your Bluetooth connection, or a setting buried in a menu.
- [ Gamepad Latency Test](https://gpadtesterpro.com/gamepad-latency-test/): This guide explains what your results mean, why two different "latency tester" tools can give you numbers that look nothing alike, how latency differs across Xbox, PS5, Switch, and PC controllers, and what you can actually do to bring it down.
- [Gamepad Controller Mapping & Testing](https://gpadtesterpro.com/gamepad-controller-mapping-test/): Controller mapping is the process of translating a gamepad's raw numbered inputs - "button 0," "axis 2" - into named actions like A, B, or left stick, so the same physical press behaves consistently in every game, emulator, and browser. This page reads those raw signals live, lets you build a custom mapping profile, and exports it as JSON, CSV, an SDL string, or a RetroArch config.
- [Joystick Deadzone Test](https://gpadtesterpro.com/joystick-deadzone-test/): A deadzone test answers exactly one question: how much noise does my stick produce at rest. It can't tell you about a stick's overall mechanical health. If your symptoms point elsewhere, here's what you're actually looking for and how to check it using the same Live Readouts above:
