Getting a new wearable device should feel exciting, yet staring at a blank screen can stall your momentum right out of the box. If you're trying to figure out how to turn on your Apple Watch for the first time or waking one that's powered down, the process takes only a few seconds once you know which button to press.
Unlike smartphones that rely primarily on a flat side button, Apple Watch models use a combination of physical hardware buttons and specific charging states to boot up. If your screen stays dark after pressing the controls, the battery might be completely drained, or the device may need a quick force restart. This guide walks you through the exact steps to power up your smartwatch, charge it properly, and troubleshoot common startup glitches.
Locating the Controls on Your Apple Watch
Before powering up, you need to know your hardware. Every Apple Watch model features two primary physical inputs on the right-hand edge:
- The Side Button: A flat, elongated button located flush against the side of the casing, right next to the circular dial. This is your main power button.
- The Digital Crown: The rotating wheel positioned above the side button. While you can use it to wake the display or access the home screen, turning the watch on relies on the side button.
Knowing the difference between these two buttons prevents confusion, especially since older mechanical watches or other fitness trackers often use a single crown for everything.
Step-by-Step Instructions to Turn On Your Apple Watch
If your watch is turned completely off, follow these steps to boot it up:
- Press and hold the side button: Locate the flat, elongated button on the right edge of the watch case. Press and hold it down for about three to five seconds.
- Wait for the Apple logo: Keep holding the button until you see the white or black Apple logo appear on the OLED display screen.
- Release the button: Once the logo shows up, let go of the side button.
- Enter your passcode: The watch will finish loading its operating system within a few seconds and display your watch face or a prompt to enter your device passcode.
If nothing happens when you hold the side button, the battery likely lacks enough charge to boot the system software.
What to Do If Your Apple Watch Won't Turn On
A blank screen doesn't always mean your hardware is broken. Most of the time, a watch that refuses to turn on simply needs power or a software reset.
Check the Battery and Charging Cable
Batteries that sit in transit or on store shelves can discharge completely to zero percent. When this happens, plugging the watch in won't instantly turn on the screen.
- Connect your magnetic charging cable to a certified USB power adapter or a computer port.
- Snap the magnetic puck onto the concave back of your Apple Watch. Make sure no plastic wrap or debris blocks the connection between the charger and the watch casing.
- Look for a green or red lightning bolt icon on the screen. If the battery is completely depleted, you might only see a small red lightning bolt next to an outline of a charging cable.
- Leave the watch on the charger for at least 15 to 30 minutes. Do not try to turn it on immediately, as deeply discharged lithium-ion cells need a baseline trickle charge before supplying enough current to power the processor.

Perform a Force Restart
If your watch screen is completely black, or if it froze midway through the boot process and got stuck displaying the Apple logo indefinitely, you can force it to reboot.
- Press and hold both the side button and the Digital Crown simultaneously.
- Keep holding both buttons down for at least 10 seconds. Do not let go when you see options or a power slider—wait until the screen goes dark and the Apple logo reappears.
- Release both buttons once the Apple logo emerges.
This procedure interrupts frozen background processes and forces the hardware controller to reinitialize the display and operating system.
Understanding Power Reserve Mode
Sometimes you might think your watch is turned off when it's actually running in a specialized low-power state. Power Reserve mode disables all smart features, cellular connections, and background sensors, displaying only a small digital clock in green text to save battery life.
- How to know if you're in Power Reserve: If your screen is dark and pressing the side button only reveals a small green clock icon in the upper right corner, your watch is in Power Reserve.
- How to exit: To return to normal operation, press and hold the side button until the Apple logo appears. Note that booting up from Power Reserve takes a minute as watchOS restarts all active background services.
Frequently Asked Questions
Why does my Apple Watch turn off by itself?
If your watch shuts down unexpectedly, it's usually due to a critically low battery or extreme temperatures. Apple Watch operating temperatures range from 32° to 95° F (0° to 35° C). Exposing the device to freezing weather or direct summer heat can trigger an automatic thermal shutdown to protect the internal battery components.
Do I need an iPhone to turn on my Apple Watch?
No. You don't need an iPhone nearby just to power the watch on or view the time. However, you do need an active pairing with an iPhone running watchOS and iOS updates to complete the initial device setup, install apps, and sync health data. You can review system compatibility details directly on the Apple Watch Official Site.
Can I turn off my Apple Watch without using the side button?
If your side button is physically damaged or stuck, you can still shut down the device by navigating to Settings on your watch, tapping General, scrolling down to the bottom of the menu, and selecting Shut Down. To turn it back on later, simply place it onto its magnetic charging cable, which automatically wakes up the system.
