You're staring at your wrist, wondering why such a tiny, sleek piece of plastic is being so stubborn. Maybe you're packing for a long flight and don't want the battery to drain. Or perhaps you're just taking a "digital detox" weekend and want the green lights on the back to stop blinking while the device sits in a drawer. Whatever the reason, figuring out how to turn off Fitbit Inspire 3 isn't as intuitive as you'd think. There is no physical "Off" switch. Honestly, Fitbit likes it that way. They want these things on your body 24/7, tracking every twitch and heartbeat. But sometimes, you just need it dead silent.
It's actually a bit of a quirk of the Inspire 3's design. Unlike the older models that felt a bit more "gadgety," the Inspire 3 leans into a minimalist, buttonless aesthetic. This means the shutdown command is buried. It's tucked away under layers of menus that most people never touch.
The Quick Way to Shut It Down
Let's get right to it. No fluff.
First, wake up that screen. A firm tap or a squeeze of the sides usually does the trick. Once you see your clock face, swipe down. Keep swiping. You'll pass notifications, you'll pass the "Exercise" app, and eventually, you'll hit Settings. It's the icon that looks like a little gear. Tap that.
Now, here is where people usually get lost. You have to scroll almost all the way to the bottom of the Settings menu. You’ll pass Brightness, Quiet Modes, and Heart Rate toggles. Ignore those. Keep going until you see Device Info. Tap it. Inside that menu, scroll down again. Finally, you’ll see the Shutdown option.

When you tap Shutdown, the Inspire 3 doesn't just die immediately. It asks for a confirmation. It's making sure you didn't just bump it while reaching for a snack. Tap the checkmark or the "Yes" prompt. The screen will go black, and the haptic motor will give a tiny, sad vibration to let you know it’s officially asleep.
That’s it. It’s off.
Why Is the Shutdown Button So Hidden?
It’s kind of annoying, right? Why hide a basic feature like "Off" three menus deep?
From a product design standpoint, Fitbit (which is now basically Google) views the Inspire 3 as a passive health monitor. If the device is off, it isn't collecting data. If it isn't collecting data, the algorithm doesn't know your Resting Heart Rate (RHR) or your Cardio Fitness Score. For the engineers in San Francisco, a turned-off Fitbit is a broken Fitbit.
Also, consider the hardware. The Inspire 3 uses a capacitive touch sensor on the sides instead of physical, clicky buttons. Physical buttons are prone to failure over time, especially with sweat and water exposure. By moving everything into the software, they made the device more water-resistant (up to 50 meters, technically). The trade-off is that you can't just hold a button for five seconds to kill the power.
A Note on Battery Health
One thing to keep in mind: if you're turning it off because the battery is low, just know that Li-ion batteries—the kind inside your Fitbit—don't like being at 0%. If you shut it down at 2% and leave it in a drawer for six months, there's a chance the battery "deep discharges." If that happens, it might never wake up again. If you're storing it long-term, try to leave it at about 50% charge before hitting that shutdown button.
Restarting vs. Shutting Down
Sometimes people search for how to turn off Fitbit Inspire 3 when what they actually need is a reboot. If your screen is frozen, or if the heart rate sensor is acting wonky and showing you at 140 BPM while you're sitting on the couch eating grapes, a simple shutdown won't always cut it.
If the screen is responsive, use the method above but look for "Restart" (though Shutdown followed by a manual turn-on achieves the same thing).
But what if the screen is black and won't respond? This is the "soft reset."
- Clip the Inspire 3 into its charging cable.
- Make sure the cable is plugged into a powered USB port.
- Locate the small button on the side of the USB plug itself (on the cable, not the tracker).
- Press that button three times, pausing for about one second between each press.
- Wait. Within about 10 seconds, the Fitbit logo should pop up on the screen.
It's a weirdly specific ritual. It feels a bit like entering a cheat code in an old video game. But it works because it forces a power cycle through the charging pins, bypassing the software menus entirely.
Common Misconceptions About the Inspire 3 Power
I see this all the time on forums like Reddit or the official Fitbit community boards: people think that if they turn off Bluetooth on their phone, the Fitbit "turns off."
Nope.
The Inspire 3 is a standalone computer. Even if it's disconnected from your phone, it’s still sitting there on your wrist, laser-firing into your capillaries to track your pulse. It will store that data for up to seven days locally. The only way to stop the sensors is the menu-based Shutdown we talked about.
Another myth? That "Water Lock" turns the device off.

Water Lock is just a screen protector. It prevents the pressure of water droplets (like in a shower or a pool) from accidentally triggering menus. Your Fitbit is still very much awake and running while Water Lock is on. To get out of Water Lock, you have to firmly double-tap the screen or firmly squeeze the sides, depending on your firmware version. Don't confuse a locked screen with a powered-down device.
What to Do if it Won't Turn Back On
So, you've successfully learned how to turn off Fitbit Inspire 3, you've had it off for a few days, and now you want it back. You tap the screen. Nothing. You squeeze the sides. Nothing.
Don't panic.
Because the Inspire 3 doesn't have a dedicated power button, the "Wake Up" process usually requires you to plug it into the charger. Once it senses a current, it automatically boots back up. If you're out in the wild without a charger and you turned it off, you might be out of luck until you get home. It's a bit of a design flaw for hikers or travelers, honestly. Always make sure you actually want it off before you commit, because you'll need that proprietary magnetic cable to bring it back to life.
Real-World Troubleshooting: The "Vibration of Death"
Occasionally, when trying to shut down or restart, users report a "continuous vibration." This is usually a sign of a firmware glitch. If you try to turn it off and it just starts vibrating and won't stop, the best move is to let the battery drain completely. Once it’s dead, charge it back to 100%. This usually clears the cache and fixes the loop.

Also, keep your app updated. A lot of the navigation issues people have with the Inspire 3—like menus disappearing—are fixed in the background via the Fitbit app on your phone.
Expert Insight: Why Bother Turning It Off?
If you're doing it to save battery for just one night, it’s probably not worth it. The Inspire 3 is rated for about 10 days of battery life. Turning it off for 8 hours might save you 1% or 2% of battery, but you lose out on your Sleep Score and SPO2 tracking. In my experience, it’s better to just leave it on unless the device is going into storage for more than three days.
Actionable Next Steps
Now that you know the secret menu path, here is what you should actually do to keep your device healthy:
- Check your firmware: Open the Fitbit app, tap your profile icon, and see if there is a pink "Update" button next to your Inspire 3. Buggy menus make shutting down harder.
- Clean the sensors: If you are turning it off because the heart rate reading is wrong, try cleaning the bottom of the tracker with a bit of rubbing alcohol first.
- Sync before shutdown: Always open the app and pull down to sync before you turn the device off. If you don't, any steps you took since the last sync will be lost forever once the power cuts.
- Carry the cable: If you plan on turning your tracker off while traveling, tuck that charging cable into your bag. Remember: you cannot turn it back on without it.
Understanding the logic behind your tech makes it a lot less frustrating when things don't work the way you expect. The Inspire 3 is a great little tracker, even if its "Off" button is playing hide-and-seek. For most users, the "Device Info" menu is the gateway to solving 90% of power-related headaches. Keep that path memorized, and you'll never be stuck with a blinking green light when you're trying to sleep again.
