How To Fix Fitbit Charge 5 Won’t Turn On (2026)

If your Fitbit Charge 5 shows a black screen and ignores taps, the cause is usually a drained battery, dirty charging contacts or a frozen restart.

This is common and almost always fixable without losing any data.

This guide walks through the fixes in the order Google recommends, and most take under an hour.

Quick answer: what to try first

Why does my Charge 5 not turn on? Start with a proper charge

A fully drained battery is the most common reason a Charge 5 looks dead.

Google’s troubleshooting page says to plug the charger into a wall outlet for 60 minutes rather than a computer USB port.

Fitbit’s Charge 5 manual says a full charge takes roughly 1 to 2 hours.

1. Plug the charging cable into a wall adapter, then into the outlet.
2. Hold the cable end near the port on the back of the tracker until it snaps on magnetically.
3. Leave it for at least 60 minutes without touching it.
4. Double-tap the screen to check the battery level.

If the battery was fully empty, the screen can stay black for several minutes after you plug it in.

Be patient with a fully drained battery

At 0%, the display may not react right away, so do not assume the tracker is dead after a minute or two.

A tracker that sat in a drawer for months may need even longer, and Android Authority notes that a very low battery can take up to about 3 hours or more.

Leaving it on the charger for a while longer costs nothing before you move on.

Clean the gold charging contacts

Dust, sweat residue and skin oils on the contacts can stop the tracker from charging at all.

• Dab a cotton swab in rubbing alcohol and wipe the gold dots on the back of the tracker.
• Wipe the gold pins on the end of the charging cable the same way.
• If it still will not charge, rub the gold dots gently with a pencil eraser, then brush away every eraser crumb.

Let everything dry before you reconnect the charger.

Check the cable and the power source

Press the gold pins on the charging cable with your finger, and they should spring back immediately.

If a pin stays pushed in or feels stuck, Google says to replace the cable.

Stop using any cable or adapter that shows browning, scorch marks or exposed wires, because that is a safety hazard.

Restart the Charge 5 with the charger button

If the screen is on but frozen, or the tracker will not wake, a forced restart often brings it back.

Restarting does not delete your fitness data.

1. Connect the tracker to its charging cable.
2. Press the small button on the flat end of the cable 3 times, pausing exactly 1 second between presses.
3. Wait about 10 seconds for the Fitbit logo to appear.

Google also lists an alternative: unplug and replug the tracker 3 times within 8 seconds, then wait 10 seconds.

Restart from the settings menu when the screen works

If the tracker is awake but acting up, you do not need the charger trick.

Open Settings from the clock screen, select Restart Device, then tap Restart.

The charger-button method is the one for an unresponsive tracker.

Clear user data as a last software step

A reset wipes the tracker, so use it only after charging, cleaning and restarting have failed.

Google lists the path for the Charge 5 as swipe down from the clock screen to open Settings, then tap Device Info, then Clear User Data.

This removes apps, stored data, personal information and saved settings from the tracker, and any activity not yet synced can be lost.

You will need to set the tracker up again in the Google Health app afterward.

If the screen shows a red X

A red X means the tracker’s software froze during a data transfer, so it is on, just stuck.

1. In the Google Health app, tap your profile picture or initial at the top right, then tap Remove this device.
2. In your phone’s Bluetooth settings, tap Forget or Unpair for the tracker.
3. In the Google Health app, tap Set Up a Device and follow the prompts.

The Fitbit app was renamed the Google Health app in May 2026, and your Charge 5 keeps its name.

Which fix matches your symptom?

When to contact Fitbit support

If the tracker still will not charge after these steps, Google points you to Fitbit Customer Support at myhelp.fitbit.com/s/support.

A failing battery or a board fault cannot be fixed at home, and a defect may qualify for repair or replacement if it is under warranty.

Ask for a repair cost before you agree to anything out of warranty, because it can approach the price of a new tracker.
