Get started

Push your goals further with built-in GPS, personalized heart-rate features, up to 7
days of battery life, and more on Fitbit Charge 4. Take a moment to review our
complete safety information at fitbit.com/safety. Charge 4 is not intended to
provide medical or scientific data.

What's in the box

Your Charge 4 box includes:

Tracker with small band
(color and material vary)

The detachable bands on Charge 4 come in a variety of colors and materials, sold
separately.

Charging cable

Additional large band

(color and material vary)

6

Set up Charge 4

For the best experience, use the Fitbit app for iPhones and iPads or Android
phones.

To create a Fitbit account, you're prompted to enter your birthdate, height, weight,
and sex to calculate your stride length and to estimate distance, basal metabolic
rate, and calorie burn. After you set up your account, your first name, last initial, and
profile picture are visible to all other Fitbit users. You have the option to share other
information, but most of the information you provide to create an account is private
by default.

Charge your tracker

A fully-charged Charge 4 has a battery life of up to 7 days. Battery life and charge
cycles vary with use and other factors; actual results will vary.

Note: The Charge 4 charging cable has a gray connector on the base of the clip. The
Charge 3 charger doesn’t work with Charge 4.

To charge Charge 4:

1. Plug the charging cable into the USB port on your computer, or a UL-certified
USB wall charger, or another low-energy charging device.

2. Clip the other end of the charging cable to the port on the back of Charge 4.
The pins on the charging clip must lock securely with the gold contacts on the

7

back of the tracker. Charge 4 vibrates, and a battery icon appears on the
screen.

Charging fully takes about 1-2 hours. While the tracker charges, you can press the
button to check the battery level. A fully-charged tracker shows a solid battery icon
with a smile.

Set up with your phone or tablet

Set up Charge 4 with the Fitbit app. The Fitbit app is compatible with most popular
phones and tablets. For more information, see fitbit.com/devices.

8

To get started:

1. Download the Fitbit app:

l Apple App Store for iPhones and iPads
l Google Play Store for Android phones

2. Install the app, and open it.

l If you already have a Fitbit account, log in to your account > tap the

Today tab > your profile picture > Set Up a Device.

l If you don't have a Fitbit account, tap Join Fitbit to be guided through a

series of questions to create a Fitbit account.

3. Continue to follow the on-screen instructions to connect Charge 4 to your
account.

When you're done with setup, read through the guide to learn more about your
new tracker and then explore the Fitbit app.

For more information, see help.fitbit.com.

See your data in the Fitbit app

Sync Charge 4 to transfer your data to the Fitbit app, where you can view your
activity and sleep data, log food and water, participate in challenges, and more.

For more information, see help.fitbit.com.

10

Wear Charge 4

PlaceCharge 4 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" on page13.

Placement for all-day wear vs. exercise

When you're not exercising, wear Charge 4 a finger's width above your wrist bone.

For optimized heart-rate tracking while exercising:

l During a workout, experiment with wearing your tracker higher on your wrist

(2 finger widths) 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.

11

l Wear your tracker on top of your wrist, and make sure the back of the device

is in contact with your skin.

l 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).

Handedness

For greater accuracy, you must specify whether you wear Charge 4 on your
dominant or non-dominant hand. Your dominant hand is the one you use for writing
and eating. To start, the Wrist setting is set to non-dominant. If you wear Charge 4
on your dominant hand, change the Wrist setting in the Fitbit app:

From the Today tab in the Fitbit app, tap your profile picture >Charge 4 tile
>Wrist >Dominant.

12

Change the band

Charge 4 comes with a small band attached and an additional large, bottom band in
the box. Boththe top and bottom bands can be swapped with accessory bands,
sold separately on fitbit.com. For band measurements, see "Band size" on page51.
Charge 3 bands are compatible with Charge 4.

Remove a band

1. Turn over Charge 4 and find the band latches.

2. To release the latch, press down on the flat button on the band.

3. Gently pull the band away from the tracker to release it.

4. Repeat on the other side.

13

Attach a new band

To attach a new band, press it into the end of the tracker until you feel it snap into
place.

If you have trouble attaching the band or if it feels loose, gently move the band
back and forth to make sure it's attached to the tracker.

vigorous activity such as running or
spinning.

In the peak zone, you’re likely doing a
short, intense activity that improves
performance and speed such as sprinting
or high-intensity interval training.

Custom heart-rate zones

Instead of using these 3 heart-rate zones, you can create a custom zone to target a
specific heart-rate range in the Fitbit app.

For more information, see help.fitbit.com.

39

Earn Active Zone Minutes

Earn Active Zone Minutes for time spent in the fat burn, cardio, or peak heart-rate
zones. To help you maximize your time, you earn 2 Active Zone Minutes for each
minute you’re in the cardio or peak zones. Heart-rate zones are personalized based
on your fitness level and age.

1 minute in the fat burn zone = 1 Active Zone Minute

1 minute in the cardio or peak zones = 2 Active Zone Minutes

There are 2 ways Charge 4 alerts you about Active Zone Minutes:

l A few moments after you enter a different heart-rate zone in the Exercise app

, so that you know how hard you’re working. The number of times your

device vibrates indicates which zone you’re in:

1 buzz = fat burn zone

2 buzzes = cardio zone

3 buzzes = peak zone

l 7 minutes after you enter a heart-rate zone throughout the day (for example,

during a brisk walk)

Fitbit Pay

Charge 4 includes a built-in NFC chip, which lets you use your credit and debit
cards on your tracker.

Use credit and debit cards

Set up Fitbit Pay in the Wallet section of the Fitbit app, and use your tracker to
make purchases in stores that accept contactless payments.

We’re always adding new locations and card issuers to our list of partners. To see if
your payment card works with Fitbit Pay, see fitbit.com/fitbit-pay/banks.

Set up Fitbit Pay

To use Fitbit Pay, add at least 1 credit or debit card from a participating bank to the
Wallet section of the Fitbit app. The Wallet is where you add and remove payment
cards, set a default card for your tracker, edit a payment method, and review recent
purchases.

From the Today tab in the Fitbit app, tap your profile picture >Charge 4

tile.

2. Tap the Wallet tile.

3. Follow the on-screen instructions to add a payment card. In some cases, your
bank might require additional verification. If you're adding a card for the first
time, you might be prompted to set a 4-digit PIN code for your tracker. Note
that you also need passcode protection enabled for your phone.

4. After you add a card, follow the on-screen instructions to turn on notifications
for your phone (if you haven't already done so)to complete the setup.

You can add up to 5 payment cards to the Wallet and choose which card to set as
the default payment option on your tracker.

43

Make purchases

Make purchases using Fitbit Pay at any store that accepts contactless payments. To
determine if the store accepts Fitbit Pay, look for the symbol below on the payment
terminal:

All customers except those in Australia:

1. When you're ready to pay, press and hold the button on your tracker for 2
seconds.

2. If prompted, enter your 4-digit tracker PINcode. Your default card appears on
the screen.

3. To pay with your default card, hold your wrist near the payment terminal. To
pay with a different card, tap to find the card you want to use, and hold your
wrist near the payment terminal.

Customers in Australia:

1. If you have a credit or debit card from an Australian bank, hold your tracker
near the payment terminal to pay. If your card is from a bank outside of
Australia, or if you wish to pay with a card that is not your default card,
complete steps 1-3 in the section above.

2. If prompted, enter your 4-digit tracker PINcode.

3. If the purchase amount exceeds $100 AU, follow the instructions on the
payment terminal. If prompted for a PIN code, enter the PIN code for your
card (not your tracker).

When the payment succeeds, your tracker vibrates and you see a confirmation on
the screen.

If the payment terminal doesn't recognize Fitbit Pay, make sure the tracker face is
near the reader and that the cashier knows you're using a contactless payment.

44

For added security, you must wear Charge 4 on your wrist to use Fitbit Pay.

Update, Restart, and Erase

Learn how to update, restart, and erase Charge 4.

Update Charge 4

Update your tracker to get the latest feature enhancements and product updates.

Regularly sync Charge 4 with the Fitbit app and let the Fitbit app run in the
background on your phone, which allows a small portion of the firmware update to
download to your tracker each time you sync. You may need to adjust your phone’s
settings to allow the Fitbit app to run in the background.

When an update is ready to install, a notification appears in the Fitbit app. After you
start the update, a progress bar appears on Charge 4 and in the Fitbit app as the
update downloads, and then installs. Keep your tracker and phone close to each
other during the update.

Note: To update Charge 4, your tracker's battery must be at least 50% charged.
Updating Charge 4 may be demanding on the battery. We recommend plugging
your tracker into the charger before starting an update.

For more information, see help.fitbit.com.

Restart Charge 4

If you can’t sync Charge 4 or you have trouble with tracking your stats, restart your
tracker from your wrist:

Open the Settings app and tap About > Reboot Device.

If Charge 4 is unresponsive:

46

1. Connect Charge 4 to the charging cable. For instructions, see "Charge your

tracker " on page7.

2. Press and hold the button on your tracker for 8 seconds. Release the button.
When you see a smiley face and Charge 4 vibrates, the tracker restarted.

Restarting your tracker reboots the device but doesn't delete any data.

Charge 4 has a small hole (altimeter sensor) on the back of the device. Don’t
attempt to restart your device by inserting any items, such as paper clips, into this
hole as you can damage your tracker.

Erase Charge 4

If you want to give Charge 4 to another person or wish to return it, first clear your
personal data:

On Charge 4, open the Settings app >About > Clear User Data.

2. Swipe up, and tap the check mark icon to erase your data.

47

Troubleshooting

If Charge 4 isn't working properly, see our troubleshooting steps below. Visit

help.fitbit.com for more information.

Heart-rate signal missing

Charge 4 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 device doesn't detect a heart-rate signal, first make sure heart-rate tracking
is turned on in the Settings app on your device. 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 4 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.

For more information, see help.fitbit.com.

GPS signal missing

Environmental factors including tall buildings, dense forest, steep hills, and even
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

48

“connecting” appear at the top of the screen. If Charge 4 can't connect to a
GPSsatellite after 10 minutes, the tracker stops trying to connect until the next time
you start a GPSexercise.

For best results, wait for Charge 4 to find the signal before you start your workout.

Other issues

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

l Won't sync
l Won't respond to taps, swipes, or button press
l Won't track steps or other data

See "Restart Charge 4" on page46 for instructions on how to restart your tracker.

For more information or to contact Customer Support, see help.fitbit.com.
