Get started

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

Tracker with small band

(color and material vary)

Charging cable

Additional large band

(color and material vary)

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

separately.

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

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.
