Apple iPhone Diagnostic
iPhone Test – Test Your iPhone Online
Check your iPhone touchscreen, display, cameras, microphone, speaker, motion sensors and browser-visible device information online, with clear manual checks for Face ID, Touch ID, battery, charging, buttons and haptics.
Complete iPhone Test
This iPhone-specific diagnostic combines browser-accessible tests with manual checks for protected Apple hardware. It is designed to work without installing an app and clearly separates what Safari can inspect from what must be checked in iOS or manually.
- Touchscreen
- Check touch-grid coverage and browser-reported multi-touch input.
- Display
- Inspect solid white, black, red, green and blue screens for visible pixel faults.
- Front camera
- Check front-camera preview, focus and framing where permission is granted.
- Rear camera
- Check rear-camera preview, focus and image stability.
- Microphone
- View live input level and make a short temporary playback recording where supported.
- Speaker
- Play a test tone and confirm sound quality manually.
- Motion sensors
- View browser-exposed orientation values after permission is granted.
- Display information
- Review screen size, pixel ratio, orientation and estimated refresh rate.
- Device information
- Review browser-visible platform and capability information.
- Face ID or Touch ID
- Manual check because raw biometric diagnostics are not exposed to webpages.
- Battery and charging
- Manual iOS and charging check.
- Buttons and haptics
- Manual physical-button and haptic-response check.
How to Test an iPhone Online
- Open this page on the iPhone itself.
- Check touchscreen response and full-screen display colours.
- Allow camera permission and test front and rear cameras.
- Allow microphone permission and check live sound plus optional playback.
- Play the speaker tone and listen for distortion.
- Allow motion access if prompted and tilt the iPhone.
- Review screen and browser-visible device information.
- Complete the manual Face ID or Touch ID, battery, charging, button and haptic checks.
- Review the iPhone Test Report.
What the iPhone Test Checks
Touchscreen and Display
Check touch coverage, display colours and visible pixel problems.
Front and Rear Cameras
Open each camera direction and inspect focus, exposure and image stability.
Microphone and Speaker
View microphone input, make local playback where supported and play a speaker tone.
Motion and Orientation
View browser-exposed device orientation after permission is granted.
Battery and Charging
Use iOS battery information and a real charging test because browser access is restricted.
Face ID, Touch ID and Buttons
Complete manual biometric, physical-button and haptic checks.
Which iPhone Tests Work in a Browser?
| iPhone feature | Browser can help? | How to confirm |
|---|---|---|
| Touchscreen | Yes | Touch or pointer events and full-screen grid coverage. |
| Dead or stuck pixels | Partly | Browser shows solid colours; you inspect the panel visually. |
| Front and rear camera | Yes, with permission | Live preview and visual image-quality check. |
| Microphone | Yes, with permission | Live level and optional temporary playback. |
| Speaker | Partly | Browser plays sound; you judge clarity and volume. |
| Motion or orientation | Sometimes, with permission | Browser-disclosed orientation values. |
| Face ID or Touch ID | No direct hardware diagnostic | Use normal iOS setup or authentication and Apple diagnostics. |
| Battery health | No reliable direct browser metric | Use iOS Battery settings. |
| Charging port | No | Use a known-good cable or charger and physical inspection. |
| Buttons and haptics | Not reliably | Manual physical and iOS-level check. |
iPhone Battery Health and Charging
A webpage cannot reliably read the same maximum-capacity battery metric shown in iOS. Use Battery settings plus a real charging check, and watch for rapid drain, unexpected heat or unstable charging.
Face ID and Touch ID Testing
Normal webpages do not receive raw biometric diagnostic data. Test Face ID or Touch ID through normal unlock and authentication flows and the relevant iOS settings.
Use the iPhone Test Before Buying a Used iPhone
Browser diagnostics can reveal obvious touch, display, camera, microphone, speaker and motion issues. For a used iPhone, also check battery health, charging, activation or account lock, mobile service, repair history and physical condition.
iPhone Test Troubleshooting
- Allow the requested permission. Camera, microphone and motion checks can require separate permission.
- Run the page on the iPhone itself. Desktop emulation cannot expose the phone's real hardware.
- Reload after changing permissions. Safari can require a reload after permission changes.
- Separate unsupported APIs from hardware faults. A browser restriction does not automatically mean the iPhone hardware is faulty.
iPhone Test Frequently Asked Questions
What is an iPhone test?
An iPhone test is a browser-based diagnostic and checklist for checking iPhone functions such as touchscreen response, display pixels, cameras, microphone, speakers, motion sensors and browser-visible device information.
Can I test my iPhone online without installing an app?
Yes. Many useful checks can run directly in Safari or another iPhone browser, although Apple restricts access to some hardware and system diagnostics.
Does this iPhone test work in Safari?
Yes for many checks, including touch, display, camera and microphone when permissions are allowed. Motion access can require a separate permission prompt, and some browser APIs remain restricted.
Can this page test the iPhone touchscreen?
Yes. Drag across the touch grid and watch cells respond to browser touch or pointer events. It can help reveal missed areas, but it does not inspect the digitiser electronics directly.
Can this page test iPhone dead pixels?
It can show full-screen white, black, red, green and blue views so you can visually inspect the display for dead, stuck or bright pixels.
Can I test the front and rear iPhone cameras?
Yes when Safari or the browser grants camera permission and exposes the requested camera direction. You still need to judge focus, image quality and lens condition visually.
Can I test the iPhone microphone?
Yes. The page can display a live microphone level and, where MediaRecorder is available, create a short temporary recording for local playback.
Can I test the iPhone speaker?
Yes. The page can play a test tone, but only you can confirm that the speaker sounds clear, loud enough and free from distortion.
Can this page test iPhone vibration or the Taptic Engine?
Not reliably. Browser access to vibration and haptic hardware on iPhone is restricted, so this page treats haptics as a manual check rather than claiming direct hardware diagnosis.
Can this page test Face ID?
No. Normal webpages do not receive raw Face ID diagnostic data. Use iPhone settings, Apple diagnostics or normal Face ID setup and authentication to check it.
Can this page test Touch ID?
No. A webpage cannot directly inspect Touch ID hardware or fingerprint sensor health.
Can this page test iPhone battery health?
No reliable cross-browser webpage can read the same battery-health metric shown by iOS. Use the iPhone's Battery settings for maximum-capacity and related battery information where available.
Can this page test the charging port?
Not directly. Use a known-good cable or charger and inspect the Lightning or USB-C port physically for looseness, debris or damage.
Can this test check iPhone motion sensors?
It can display browser-exposed device-orientation values after permission is granted. That is useful for checking whether motion events are reaching the webpage, but it is not a complete gyroscope or accelerometer calibration.
Can this test identify my exact iPhone model?
Not reliably. Modern browsers intentionally reduce device-identification detail, so the page reports browser-visible platform, screen and capability information instead of guessing an exact model.
Does Device Tests upload my camera or microphone recordings?
The live camera and microphone streams used by the tool are handled in the browser. Short microphone playback recordings are created as temporary local browser objects and are not uploaded by this tool.
Why does a test say Manual check?
Some iPhone functions cannot be conclusively measured by a normal webpage. Manual check means you should confirm the result visually, audibly, physically or in iOS settings.
What should I test if I am buying a second-hand iPhone?
Run this iPhone Test, then use the Used Phone Test to check battery and charging, account or activation lock, connectivity, physical condition and ownership-related items.
