Apple Watch Ultra: How to Use the Built-In Siren to Signal for Help

If you ever become lost, injured, or have some other emergency situation and want to draw attention to your location, ‌Apple Watch Ultra‌ includes an 86-decibel siren that you can use.



The siren uses a unique sound signature that incorporates two distinct alternating patterns, which can repeat for several hours. The first pattern suggests distress, while the second mimics the universally recognized SOS pattern, and the siren can be heard up to 600 feet or 180 meters away.

As such, it’s pretty loud, so don’t turn it on in enclosed environments or hold your watch close to your ears when the Siren is sounding.

How to Turn on Siren on Apple Watch Ultra

You can turn on the Siren using the Action button or the side button.

Using the Action Button:

  1. Press and hold the Action button until the Siren slider appears.
  2. Drag the Siren slider to start a countdown.
  3. After the countdown, the Siren starts.

Alternatively, you can press and hold the Action button to start the countdown, then continue holding the Action button until Siren starts. If you don’t want the Siren going off using this continual hold action, go to Settings -> Action Button, and switch off the toggle next to Hold to Turn On.


Using the Side Button

  1. Press and hold the Side button until the Siren slider appears.
  2. Drag the Siren slider to start a countdown.
  3. After the countdown, the Siren starts.

How to Cancel the Siren on Apple Watch Ultra

You can cancel the Siren during the countdown. If you’re holding the Action button, simply release it to cancel. If you initiated the countdown by dragging the Siren slider, cover the watch display with the palm of your hand for at least three seconds to cancel.

To cancel the Siren while it’s sounding, simply tap the central Stop button in the Siren app.

Apple Watch Ultra: How to Use the New Optimized Charge Limit Feature

All Apple Watch models running watchOS 7 or later include a Battery Health feature called Optimized Battery Charging that extends the total battery life of your Apple Watch by learning from your habits and waiting to finish charging all the way up until you need your ‌Apple Watch.



Apple Watch Ultra can last up to 36 hours on a single charge – the longest battery life of any Apple Watch – and to extend battery life even further, ‌Apple Watch Ultra‌ offers even more intelligent battery charge optimization with something called Optimized Charge Limit.

On by default when you set up your Apple Watch, Optimized Charge Limit use on-device machine learning to analyze your daily usage and determine when to charge to an optimized limit and when to allow a full charge. The feature changes dynamically depending on how you use your ‌Apple Watch Ultra‌. For example, based on usage patterns, your watch might charge to 100% on some days, and less on others.

When Optimized Charge Limit is active, an open charge ring is displayed when you connect your ‌Apple Watch Ultra‌ to its charger. It’s possible to charge your watch beyond the optimized limit by following the steps below.

watch

How to Charge Apple Watch Ultra Beyond the Optimized Charge Limit

  1. Make sure that your ‌Apple Watch Ultra‌ is connected to its charger.
  2. Tap the watch display to wake the charging screen, then tap the circle with the green or yellow charging icon.
  3. Tap Charge to Full Now.

How to Disable Optimized Charge Limit

If you want your ‌Apple Watch Ultra‌ to fully charge every time its placed on the charge, disable Optimized Battery Charging by following these simple steps.

  1. Open the Settings app on your ‌Apple Watch Ultra‌.
  2. Scroll down and tap Battery.
  3. Tap Battery Health.
  4. Toggle off the switch next to Optimized Charge Limit.
  5. Choose Turn Off Until Tomorrow or Turn Off.

Help Optimized Charging Identify Locations

Optimized charging is designed to activate only in locations where you spend the most time, such as your home and place of work. The feature doesn’t turn on when your usage habits are more variable, such as when you travel.

To help your ‌Apple Watch Ultra‌ identify situations where Optimized Charge Limit shouldn’t be used, turn on the following location settings in the Settings app on your ‌Apple Watch Ultra‌:

  • Privacy -> Location Services -> Location Services
  • Privacy > Location Services > System Services > System Customization
  • Privacy > Location Services > System Services > Significant Locations > Significant Locations

The location information for this feature remains on your watch and none of it is sent to Apple.

Apple Watch Ultra: How to Customize the Action Button

Apple Watch Ultra features a customizable Action button on the left side of the case that is capable of performing a variety of functions. This article explains what it can do, and how you can configure it.



Apart from activating the Siren, the Action Button on ‌Apple Watch Ultra‌ can be customized to perform a number of functions, offering quick access to them without you having to tap through various screens.

When you first set up your ‌Apple Watch Ultra‌, you’ll be invited to assign one of the following functions to it:

  • Workout
  • Stopwatch
  • Waypoint
  • Backtrack
  • Dive
  • Flashlight
  • Shortcut
  • None

You can customize your selection further, depending on the app or function chosen. If you chose the Workout app, for example, pressing the Action button once will open the Workout app, but you can also assign the “First Press” function within the app to start a specific workout.



But that’s not all. When you’ve started the activity, you can then press again to perform a secondary function, such as marking segments or laps in a track workout, or switching from cycling to running in a triathlon. Again though, what function this is will depend on the current activity.

How to Map Functions to the Action Button

Once your ‌Apple Watch Ultra‌ is set up, you can re-assign functions to the Action button via a new menu right on your wrist, like so.

  1. On ‌Apple Watch Ultra‌, launch the Settings app.
  2. Scroll down and tap Action Button.
  3. Tap the menu under “Action” and select one of the following options: Workout, Stopwatch, Waypoint, Backtrack, Dive, Flashlight, and Shortcut.

    settings

  4. Tap the arrow in the left-hand corner to go back to Action Button settings.
  5. Tap the menu under “App” if it appears, then select an app to perform the action. Some actions, such as Flashlight, don’t show the App option.
  6. Tap the arrow to go back.
  7. Tap the menu under “First Press” if it appears, then select an action. Some features allow different actions to happen on the first and second press of the button.

Tips appear on the screen under “Gestures” explaining how the Action button works with the settings that you’ve assigned to it. For example, tips for an outdoor walk show you that pressing the Action button once starts a workout, and pressing the Action button and the side button at the same time pauses the workout.

Configuring the Action Button via iPhone

You can also use the iOS Watch app to configure what the Action button on the ‌Apple Watch Ultra‌ does.

  1. Launch the Watch app on your iPhone.
  2. Tap the My Watch tab if it’s not already selected.
  3. Tap Action Button.
  4. Under “Action,” tap the currently selected action to change it.
  5. Select from one of the following options: Workout, Stopwatch, Waypoint, Backtrack, Dive, Flashlight, and Shortcut.
  6. Tap Action Button to go back to the previous menu.
  7. Tap the menu under “App” if it appears, then select an app to perform the action. Some actions, such as Flashlight, don’t show the App option.
  8. Tap the arrow to go back.
  9. Tap the menu under “First Press” if it appears, then select an action. Some features allow different actions to happen on the first and second press of the button.

Note that tips on the screen under “Gestures” explaining how the Action button works with the settings that you’ve assigned to it.

Note that if you want to pause the current action, you can press and hold both the Action and Side buttons at the same time. Try to avoid pressing the Side button or the Digital Crown accidentally when you press the Action button. Your Apple Watch will do whatever is assigned to the Action button if you happen to press another button at the same time, unless a button combination is configured.
