You just unboxed it. That sleek, matte-finish tracker is sitting in your palm, smelling like fresh silicone and promise. You want to see the screen glow. You want to start tracking those steps. But there’s a weirdly common frustration that hits almost every new owner: figuring out how to switch on a Fitbit for the first time.
It shouldn't be hard. Most electronics have a giant "Power" symbol. Fitbit? Not so much. Depending on whether you're holding an Inspire 3, a Charge 6, or a beefy Sense 2, the "on" switch might be a physical button, a haptic groove, or—infuriatingly—nothing at all until you plug it into a wall.
Honestly, the design philosophy at Fitbit has shifted over the years. They moved away from bulky buttons to create better water resistance. That's great for your laps in the pool, but it makes the initial setup feel like a guessing game.
The First Rule of Fitbit: Plug it in
Most people try to long-press the sides of the device immediately. Stop.
If your Fitbit is brand new, it's likely in "shipping mode." This is a deep-sleep state used to preserve the lithium-ion battery while the device sits in a warehouse or on a retail shelf. You can mash the buttons until your thumb gets sore, but it won't wake up.
To how to switch on a Fitbit when it’s fresh out of the box, you must connect it to its proprietary charging cable. Once the pins align and the magnets snap into place, the device feels the current. The Fitbit logo should jump onto the screen. This "jumpstarts" the firmware.
If you’ve plugged it in and... nothing? Check the gold pins. Even a tiny bit of dust or packing lint can break the connection. I've seen people return perfectly good Sense 2 units because a microscopic piece of plastic was stuck in the charging port. Give it a quick wipe with a soft cloth.

Understanding the Different Button Types
Fitbit uses three main interaction styles. Knowing which one you have changes everything.
- Physical Buttons: Found on older Versa models and the new Google-integrated watches. You push them. They click. Simple.
- Haptic Indents: The Charge 5 and Charge 6 use these. It’s not a real button. It’s a solid-state sensor that vibrates when you squeeze it. If the battery is bone-dry, this sensor won't provide feedback, making you think the watch is broken.
- Touch Only: Some of the smaller Luxe or Inspire models rely almost entirely on the screen or a side-squeeze.
How to Switch on a Fitbit After a Total Shutdown
Let's say your battery died and the watch turned itself off. Or maybe you intentionally shut it down to save power while you weren't wearing it for a weekend trip.
To turn it back on, press and hold the side button for about three to five seconds. For the Versa and Sense lines, this is usually the button on the left-hand side. You’ll feel a distinct buzz. That haptic motor is the first sign of life.
If it’s a Luxe or an Inspire 2, there isn't a traditional power button. You basically have to plug those back into the charger to "wake" them if they've completely powered down. It’s a bit of a tethered existence, but it keeps the device footprint tiny.
What if the Screen Stays Black?
This is where the panic sets in. You’ve held the button. You’ve plugged it in. The screen is a void.
Before you call customer support, try a "Force Restart." This is the tech equivalent of a cold shower. For most modern trackers like the Charge 6, you’ll need to find the button on the actual charging cable itself. Yes, the cable has a button. Press it three times quickly, with a one-second pause between each press.
On a Versa 4 or Sense 2, hold the side button down for a solid 10 to 12 seconds. Don't let go when the screen flickers. Keep holding until the Fitbit logo appears. It’s a long time. You’ll think you’re doing it wrong. You aren’t. Just keep holding.

The Battery Misconception
A lot of users think their Fitbit is broken when it's actually just "deeply" discharged. If a lithium-ion battery hits 0% and stays there for weeks, it enters a protective state.
Plug it into a low-voltage source, like a laptop USB port, rather than a high-speed phone "fast charger." Sometimes the lower, steady current is better for coaxing a dead battery back to life. Leave it there for two hours. Don't touch it. Don't check it. Just let it sit.
Connecting to the App is Part of the Power Process
You can’t really consider the device "on" until it’s synced. The Fitbit app is the brain. Even if the screen is glowing, it might just be showing a "fitbit.com/setup" message.
- Make sure your phone's Bluetooth is toggled on.
- Open the Fitbit app (now heavily integrated with Google).
- Tap the devices icon in the top left.
- Follow the "Add Device" prompts.
The app will often push a firmware update immediately. Do not—under any circumstances—unplug the watch or close the app during this. If the power cuts mid-update, you might "brick" the device. That's a fancy way of saying you've turned your $200 tracker into a very expensive rubber bracelet.
Why Does My Fitbit Keep Turning Off?
If you've mastered how to switch on a Fitbit but it won't stay on, you're looking at a different set of problems.
The most common culprit is "Water Lock." If you were just in the shower or a pool, the device might have disabled the screen to prevent "ghost touches" from water droplets. Double-tap the screen firmly to turn off Water Lock.
Another possibility? The "Always-On Display" settings. If you’re used to a watch that’s always visible, and your new Fitbit keeps going dark, it’s not turning off—it’s just sleeping to save battery. You can change this in the "Settings" menu under "Display," but be warned: it will cut your battery life in half. Easily.
Actionable Steps for a Flawless Startup
If you are struggling right now, follow this specific sequence. It works 95% of the time.
- Clean the contacts: Use a tiny bit of rubbing alcohol on a cotton swab for both the watch and the charger.
- Wall over Laptop: Try a different power source. Some USB ports on older computers don't output enough juice to wake a dead tracker.
- The 15-Second Hold: On almost any Fitbit with a button, 15 seconds is the magic number to trigger a hardware reset.
- Check the App: If the watch is vibrating but the screen is dark, check the app to see if it’s syncing. If it is, your screen might be dead, but the "insides" are working.
Once the logo pops up, you're golden. Just remember that these devices are essentially tiny computers strapped to your wrist. Sometimes they just need a minute to find their feet. If you've tried the cable reset and the long-hold and you still have a black screen, it’s time to check your warranty status on the Fitbit help site. Most of these trackers have a one-year limited warranty that covers "dead on arrival" hardware.
To get the most out of your newly powered-on device, go straight into the settings and turn off "GPS-Always" unless you’re about to go for a run. It's the fastest way to make sure you don't have to learn how to switch it back on again tomorrow morning. Keep the charging pins dry, avoid extreme heat, and your Fitbit should wake up instantly every time you need it.
