DualSense Calibration: Free Web Tool to Fix PS5 Controller Stick Drift
Professional DualSense calibration tool that permanently fixes stick drift through firmware-level recalibration. Our free software recalibrates analog stick center positions and movement range on DualSense, DualSense Edge, and DualShock 4 controllers. This method uses WebHID to save calibration data directly to controller firmware via USB connection.
Free DualSense Calibration Tool (WebHID)
Important DualSense Calibration Notes: This tool requires USB connection (Bluetooth not supported) and a Chromium-based browser with WebHID API. Keep your controller battery charged during the process. Use at your own risk - this is experimental software developed through reverse-engineering.
Why Use Our DualSense Calibration Tool
Free DualSense Calibration Software
Completely free DualSense calibration tool developed through reverse-engineering PlayStation controller protocols. This DualSense calibration software requires no downloads - works directly in your browser via WebHID. Open-source project with ongoing community development.
Permanent DualSense Calibration Results
DualSense calibration data is saved directly to your controller's firmware, making changes permanent across all devices. Our method recalibrates analog stick center position (0,0) and movement range to fix minor drift issues.
Multi-Controller DualSense Calibration Support
DualSense calibration works with DualShock 4 (V1 & V2), DualSense, and DualSense Edge controllers. Note: DualSense Edge requires hardware modification to disable write protection. Standard controllers work without modifications.
How DualSense Calibration Works
Connect Controller for DualSense Calibration
Use a USB cable to connect your DualSense, DualSense Edge, or DualShock 4 controller for DualSense calibration. Bluetooth connections are not supported. Ensure controller battery is charged before starting.
DualSense Calibration: Stick Center
The DualSense calibration tool samples where your analog sticks naturally rest and resets the X and Y axis default positions to (0,0). This step recalibrates the center point, helping fix minor drift caused by calibration offset.
DualSense Calibration: Stick Range
Rotate both analog sticks in full circles during DualSense calibration to calibrate their complete range of motion. The tool records maximum movement range to ensure accurate input detection.
Save DualSense Calibration to Firmware
DualSense calibration settings are written permanently to your controller's internal memory. Changes persist across all connected devices including PS5, PC, and other platforms.
Supported Controllers for DualSense Calibration
- ✓Sony DualSense (full support)
- ✓Sony DualSense Edge (with hardware mod)
- ✓Sony DualShock 4 V1 & V2
- ✓Clone detection available for DualShock 4
WebHID support required. Works on Chrome, Edge, Opera, and other Chromium-based browsers. Firefox and Safari not supported.
Understanding DualSense Calibration Technology
What Causes Drift
Stick drift in DualSense controllers occurs when analog sticks register movement even at rest. Common causes include: (1) Potentiometer wear from extended use (2) Dust and debris lodged under analog stick housing (3) Calibration offset where the controller's center position drifts from true (0,0). Our tool addresses calibration offset issues through firmware-level adjustments.
While physical cleaning (compressed air, isopropyl alcohol) helps with dust-related drift, and hardware replacement fixes worn components, calibration drift requires recalibration to reset the controller's stored center position and range values. This tool resets these firmware-stored values through professional methods.
The calibration process uses WebHID (Web Human Interface Device) API to send USB commands directly to the controller. Commands include Feature IDs 0x82 (Set Calibration) and 0x83 (Get Calibration), which read and write calibration data to the controller's internal memory.

DualSense Calibration vs Other Drift Solutions
| Solution Method | Cost | Effectiveness | Permanence | Difficulty |
|---|---|---|---|---|
| Web Calibration Tool | Free | Good for calibration drift | Permanent | Easy (web browser) |
| Buy New Controller | $70-200 | Solves all issues | Until new wear occurs | None |
| Replace Analog Module | $10-30 + tools | Fixes hardware damage | Depends on quality | High (soldering required) |
| Compressed Air Cleaning | $5-10 | Good for dust/debris | Temporary | Easy |
| Increase Software Deadzone | Free | Masks symptoms only | Per-game setting | Medium |
Web-based DualSense calibration is the best solution for fixing calibration offset drift. DualSense calibration won't fix physically worn potentiometers (which need hardware replacement) or dust buildup (which needs cleaning). DualSense calibration is best used after replacing analog modules or when experiencing minor center drift from calibration offset issues.
When DualSense Calibration Helps vs. When It Doesn't
⚠️Symptoms Fixed by DualSense Calibration
- • Character slowly drifts when sticks released
- • Camera pans without input
- • Stick center reads as off-center position
- • Inconsistent neutral position detection
- • After replacing analog stick modules
🎮When DualSense Calibration Won't Help
- • Physically broken potentiometers
- • Worn out analog stick sensors (1000+ hours)
- • Dust and debris inside stick housing
- • Cracked or damaged analog modules
- • Requires hardware repair/replacement instead
✅After Successful DualSense Calibration
- • Sticks properly centered at (0,0)
- • No drift when sticks at rest
- • Accurate input detection restored
- • Works across all games and platforms
- • Calibration persists in controller firmware
Important Calibration Notes
This is an experimental tool developed through reverse-engineering. While it has helped many users fix calibration drift, use at your own risk. Always ensure controller battery is charged before starting. Firmware updates may affect compatibility.
What This Tool Does:
- • Resets analog stick center position to (0,0)
- • Recalibrates stick movement range
- • Writes calibration data to controller firmware
- • Works via WebHID over USB connection
Best Use Cases:
- • After replacing worn analog stick modules
- • Fixing minor calibration offset drift
- • Free alternative to buying new controller
- • When center position reads incorrectly
DualSense Calibration FAQ
What does this DualSense calibration tool do?
This web-based DualSense calibration tool recalibrates your DualSense, DualSense Edge, or DualShock 4 controller's analog stick center position and movement range. It samples where your sticks naturally rest and resets the X/Y axis default positions to (0,0), fixing calibration offset drift. The tool saves these settings directly to your controller's firmware via WebHID over USB.
Will DualSense calibration fix my stick drift?
It depends on the cause. This fixes drift caused by calibration offset (when the controller's stored center position is incorrect). It will NOT fix drift from physically worn potentiometers (which need hardware replacement) or dust buildup (which needs cleaning with compressed air). Best used after replacing analog modules or for minor center position drift.
Which browsers work with DualSense calibration?
Requires a Chromium-based browser with WebHID API support: Chrome, Edge, Opera, Brave. Firefox and Safari do NOT support WebHID. You must connect your controller via USB (Bluetooth is not supported). Ensure your controller battery is charged before starting.
Is DualSense calibration safe? Can it break my controller?
This tool is experimental, developed through reverse-engineering PlayStation controller protocols. While many users have successfully used it, there is potential risk. Use at your own risk. Always keep controller battery charged during the process. Firmware updates may affect compatibility. Not officially affiliated with Sony.
Does DualSense calibration work with DualSense Edge?
DualSense Edge is supported but requires hardware modification. The stick module's flash chip is write-protected by default. You must apply +1.8V to a specific test point on the PCB to disable write protection before calibration. Standard DualSense and DualShock 4 controllers work without modification.
Can I undo DualSense calibration?
Once saved to firmware, calibration persists permanently across all devices. There is no built-in undo function. However, you can re-run the process again if needed to adjust the center position. First-time users should carefully follow on-screen instructions and ensure sticks are at neutral position when sampling center.
