How to Turn Off Wrist Detection on Apple Watch, Pros & Cons?

Apple Watch comes with a Wrist Detection feature that protects your information by locking the watch when you’re not using it. However, it also means the watch locks every time you remove it from your wrists which can be annoying. In this article, let us see how to turn on or off the Wrist Detection on Apple Watch. We’ll also see what happens when you disable Wrist Detection and how it impacts your usage.

What is Wrist Detection in Apple Watch?

Wrist Detection lets the Apple Watch know if you’re wearing it. The watch has several sensors on the back that help it identify if you’re wearing it on your wrist. Removing the watch locks it with a passcode to protect your data from unauthorized access.

If you’re someone who removes the watch often, you may get annoyed every time it locks automatically and hides the information from the screen. In short, Wrist Detection for Apple Watch is what Touch ID is for iPhones. However, it’s not as convenient or feasible as the latter.

You need to turn off the wrist detection feature to make the Apple Watch stay unlocked even when you’ve removed it from your hand.

How Does Wrist Detection Work?

How Apple Watch Wrist Detection Works

Apple Watch uses a Photoplethysmography (PPG) sensor at the rear to determine if it’s wrapped around your wrist. The sensor involves a low-intensity IR light source, followed by a photodetector, and is also used in measuring the heart rate.

The setup emits light on your skin and measures the amount that reflects. If no light bounces off, it means the watch is not on your wrist, which is when it locks it with a passcode. It works only if you have Wrist Detection enabled in settings.

Pros & Cons of Wrist Detection

Advantages of Wrist Detection

  • Security: Ensures that no other party can access or use your Apple Watch without your passcode. If it’s disabled, you’ll have to lock the watch manually.
  • Privacy: Any sensitive information is hidden from the screen while not wearing the watch. This includes your reminders, app notifications, and more.
  • Health: It facilitates important health measurement features like blood oxygen, automatic heart rate, and sleep tracking.

Disadvantages of Wrist Detection

  • Battery: Since wrist detection uses sensors to check if it’s on your wrists constantly, it does increase overall battery consumption. However, it shouldn’t be the sole reason to disable it.
  • Inconvenience: It can annoy people who remove the watch multiple times a day.
  • Problems with Tattoos: The Wrist Detection may not work properly if you have dark tattoos on your wrist. Apple confirmed that permanent or temporary changes to your skin, like tattoos, may affect heart rate sensor performance. This is because the ink, pattern, or color may block the light from the sensor.

Apple Watch Wrist Detection Not Working

  • Ensure you wear the Apple Watch correctly- not too loose or too tight.
  • If the watch is too loose, it may trigger the passcode lock if there’s no skin contact.
  • Consider buying a new strap or punching extra holes in the existing one if you have slim wrists.
  • Sleeves of clothes may sit between the watch and your wrist, affecting the detection.
  • If a tattoo on your wrist affects the detection, change the hand you wear the watch on.
  • Restart the watch and check for software updates if it still does not work.

3. Can You Use Passcode Without Wrist Detection?

You can turn off the Passcode lock on your Apple Watch while keeping Wrist Detection on for all features to work properly. However, the vice versa is impossible, meaning you cannot use Passcode without Wrist Detection.

4. Do ECG & Raise to Wake Work With Wrist Detection Disabled?

Raise to Wake the display works even with wrist detection disabled. And so is the case with ECG. Both the features work fine without wrist detection.

5. Should You Use Apple Watch Without Wrist Detection?

There’s no harm in using Apple Watch without the wrist detection feature. It’s just that the watch will no longer know if you’re wearing it, and real-time health measurement features like background heart rate, blood oxygen, and more will not work.

However, if an elder or vulnerable person is using the watch, we suggest keeping wrist detection enabled to allow the watch to auto-call emergency services in case of a hard fall.
