Get started

Boost your routine with Fitbit Charge 6*, the only premium fitness tracker with Google built-in. With the fitness tools you need to stay motivated and crush your goals, running your day and your routine has never been easier.

Take a moment to review our complete safety information at support.google.com. Charge 6 is not intended to provide medical or scientific data. *Fitbit Charge 6 works with most phones running Android 9.0 or newer or iOS 15 or newer and requires a Google Account, Fitbit mobile app, and internet access.

Some features require a Fitbit mobile app and/or a paid subscription. See fitbit.com/devices for more information.

What’s in the box

Your Charge 6 box includes:

• Tracker with a small band (color and material varies)
• Charging cable
• Additional large band

The detachable bands on Charge 6 come in a variety of colors and materials, sold separately.

Charge your tracker

A fully-charged Charge 6 has a battery life of up to 7 days. Battery life and charge cycles vary with use and other factors; actual results will vary.

To charge Charge 6:

1. Plug the charging cable into the USB port on your computer, a UL-certified USB wall charger, or another low-energy charging device.
2. Hold the other end of the charging cable near the port on the back of the tracker until it attaches magnetically. Make sure the pins on the charging cable align with the port on the back of your tracker.

Charging fully takes about 1-2 hours. While Charge 6 charges, double-tap the screen or press the button to turn it on and check the battery level. Swipe right on the battery screen to use Charge 6. A fully charged tracker shows a solid battery icon.

Set up

Set up Charge 6 with the Fitbit app for iPhones and iPads or Android phones. The Fitbit app is compatible with most popular phones. See fitbit.com/devices to check if your phone is compatible.

Wear Charge 6

Wear Charge 6 around your wrist. If you need to attach a different size band, or if you purchased another band, see the instructions in “Change the band”.

Placement for all-day wear vs. exercise

When you’re not exercising, wear Charge 6 a finger’s width above your wrist bone. In general, it’s always important to give your wrist a break regularly by removing your tracker for around an hour after extended wear.

We recommend removing your tracker while you shower. Although you can shower while wearing your tracker, not doing so reduces the potential for exposure to soaps, shampoos, and conditioners, which can cause long-term damage to your tracker and may cause skin irritation.

For optimized heart-rate tracking while exercising:

• During a workout, experiment with wearing your tracker a bit higher on your wrist for an improved fit. Many exercises, such as bike riding or weight lifting, cause you to bend your wrist frequently, which could interfere with the heart-rate signal if the tracker is lower on your wrist.
• Wear your tracker on top of your wrist, and make sure the back of the device is in contact with your skin.
• Consider tightening your band before a workout and loosening it when you’re done. The band should be snug but not constricting (a tight band restricts blood flow, potentially affecting the heart-rate signal).

Fasten the band

1. Place Charge 6 around your wrist.
2. Slide the bottom band through the first loop in the top band.
3. Tighten the band until it fits comfortably, and press the peg through one of the holes in the band.
4. Slide the loose end of the band through the second loop until it lies flat on your wrist. Make sure the band isn’t too tight. Wear the band loosely enough that it can move back and forth on your wrist.

Notifications from your phone

Charge 6 can show calls, texts, calendars, and app notifications from your phone to keep you informed. Keep your tracker within 30 feet of your phone to receive notifications.

Set up notifications

Check that Bluetooth on your phone is on and that your phone can receive notifications (often under Settings Notifications).

Then set up notifications:

1. From the Today tab in the Fitbit app, tap the devices icon Charge 6.
2. Tap Notifications.
3. Follow the on-screen instructions to pair your tracker if you haven’t already. Call, text, and calendar notifications are turned on automatically.

Answer or reject phone calls

If paired with an iPhone or Android phone, Charge 6 lets you accept or reject incoming phone calls. To accept a call, tap the green phone icon on your tracker’s screen.

Note that you can’t speak into the tracker—accepting a phone call answers the call on your nearby phone.

To reject a call, tap the red phone icon to send the caller to voicemail. The caller’s name appears if that person is in your contacts list; otherwise, you see a phone number.

Timekeeping

Alarms vibrate to wake or alert you at a time you set. Set up to 8 alarms to occur once or on multiple days of the week. You can also time events with the stopwatch or set a countdown timer.

Set an alarm
Set one-time or recurring alarms with the Alarms app. When an alarm goes off, your tracker vibrates. When setting an alarm, turn on Smart Wake to allow your tracker to find the best time to wake you starting 30 minutes before the alarm time you set.

It avoids waking you during deep sleep so you’re more likely to wake up feeling refreshed. If Smart Wake can’t find the best time to wake you, your alarm alerts you at the set time.

Dismiss or snooze an alarm
When an alarm goes off, your tracker vibrates. To dismiss the alarm, swipe up from the bottom of the screen and tap the dismiss icon. To snooze the alarm for 9 minutes, swipe down from the top of the screen or press the button.

Snooze the alarm as many times as you want. Charge 6 automatically goes into snooze mode if you ignore the alarm for more than 1 minute.

Activity and Wellness

Charge 6 continuously tracks a variety of stats whenever you wear it, including hourly activity, heart rate, and sleep. Data automatically syncs with the Fitbit app throughout the day.

See your stats

Swipe up from the clock face to see your daily stats, including:

• Core stats Steps taken today, distance covered, Active Zone Minutes, and calories burned.
• Exercise Number of days you met your exercise goal this week
• Heart rate Current heart rate and resting heart rate
• Hourly activity The number of hours today you met your hourly activity goal
• Sleep Sleep duration and sleep score

Track your hourly activity
Charge 6 helps you stay active throughout the day by keeping track of when you’re stationary and reminding you to move.

Reminders nudge you to walk at least 250 steps each hour. You feel a vibration and see a reminder on your screen 10 minutes before the hour if you haven’t walked 250 steps. When you meet the 250-step goal after receiving the reminder, you feel a second vibration and see a congratulatory message.

Use the EDA Scan app

The EDA Scan app on Charge 6 detects electrodermal activity which may indicate your body’s response to stress. Because your sweat level is controlled by the sympathetic nervous system, these changes can show meaningful trends in how your body responds to stress.

1. On your tracker, swipe left or right to the EDA Scan app and tap to open it.
2. To begin a scan the same length as your previous scan, tap the play icon. To change the length of time for the scan, swipe up tap Edit length, and tap your desired number of minutes.
3. Gently hold the sides of your tracker with your thumb and index finger.
4. Remain still and keep your fingers on your tracker until the scan is complete.
5. If you remove your fingers, the scan pauses. To resume, place your fingers back on the sides of your tracker. To end the session, tap End session.
6. When the scan is complete, tap a mood to reflect on how you feel, or tap Skip.
7. Swipe up to see the summary of your scan, including your number of EDA responses, heart rate at the start and end of the session, and reflection if you logged a reflection.
8. Tap Done to close the summary screen.
9. To see more details about your session, open the Fitbit app on your phone. From the Today tab, tap the Mindfulness tile Your Journey.

• For best results, make sure your tracker’s battery is above 80% before you track an exercise longer than 2 hours with built-in GPS.

Check your heart rate

Charge 6 personalizes your heart rate zones using your heart rate reserve, which is the difference between your maximum heart rate and your resting heart rate.

To help you target the training intensity of your choice, check your heart rate and heart rate zone on your tracker during exercise. Charge 6 notifies you when you enter a heart rate zone.

Troubleshooting

If Charge 6 isn’t working properly, see our troubleshooting steps below.

Heart-rate signal missing

Charge 6 continuously tracks your heart rate while you’re exercising and throughout the day. If the heart rate sensor on your tracker has difficulty detecting a signal, dashed lines appear.

If your tracker doesn’t detect a heart-rate signal, first make sure heart-rate tracking is turned on in the Settings app on your tracker.

Next, make sure you’re wearing your tracker correctly, either by moving it higher or lower on your wrist or by tightening or loosening the band.

Charge 6 should be in contact with your skin. After holding your arm still and straight for a short time, you should see your heart rate again.

GPS signal missing
Environmental factors including tall buildings, dense forests, steep hills, and thick cloud cover can interfere with your tracker’s ability to connect to GPS satellites.

If your tracker is searching for a GPS signal during an exercise, you’ll see GPS connecting appear at the top of the screen. If Charge 6 can’t connect to a GPS satellite, the tracker stops trying to connect until the next time you start a GPS exercise.

For best results, wait for Charge 6 to find the signal before you start your workout.

Other issues
If you experience any of the following issues, restart your tracker:

• Won’t sync
• Won’t respond to taps, swipes, or button press
• Won’t track steps or other data
• Won’t show notifications
