Apple Watch Power Reserve: How to Enable & Disable

Apple Watch Power Reserve Mode: A Comprehensive Guide

The Apple Watch typically offers around 18 hours of battery life, contingent upon usage patterns. Should the battery level become critically low, activating Power Reserve mode allows the watch to display the time for up to 72 hours.

When Power Reserve is engaged, all standard Apple Watch functions are suspended, with the sole exception being the ability to view the time. This time display is activated by a press of the side button, remaining visible for six seconds.

Understanding Power Reserve Functionality

In this mode, apps, glances, and all other typical watch features become inaccessible. Communication between your Apple Watch and iPhone is also temporarily halted.

The primary benefit of utilizing Power Reserve is a significant reduction in power consumption. This extends basic timekeeping functionality for a prolonged duration, providing time to recharge the device.

Enabling Power Reserve Mode

Several methods exist for activating Power Reserve mode on your Apple Watch.

If the battery reaches 10%, a “Low Power” screen will appear. Simply tap the “Power Reserve” button on this screen.

A confirmation prompt will then be displayed. Select “Proceed” to initiate Power Reserve mode.

Using Glances to Activate

Alternatively, Power Reserve can be enabled through Glances. Swipe upwards from the main watch face.

Then, swipe left or right until the Battery glance is located. Tap the “Power Reserve” button within the Battery glance.

A confirmation message, visually distinguished by a green color instead of red, will appear. Tap “Proceed” to activate the mode.

Side Button Activation

You can also activate Power Reserve by pressing and holding the side button until the appropriate screen appears.

Note: If a Passcode is set on your watch, a “Lock Device” option will also be visible on this screen.

Slide the “Power Reserve” slider to the right to enable the mode. Unlike other methods, this approach doesn't present a confirmation screen.

Returning to Normal Mode

Once in Power Reserve, the watch’s primary function is displaying the time, which appears in green when the side button is pressed.

To exit Power Reserve and restore normal functionality, a reboot is required. Press and hold the side button until the Apple logo becomes visible.

The watch will then restart in normal mode. Ensure sufficient battery life for the reboot process; connecting the charger during startup is recommended if power is limited.

Limitations and Considerations

Power Reserve effectively transforms your smartwatch into a basic timekeeping device. Certain features available on traditional, non-smart watches may be unavailable during this mode.

However, when extended battery life is crucial, Power Reserve mode provides a valuable solution.
