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.

To get started:

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

Wear Charge 4
PlaceCharge 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 page13.
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. Boththe top and bottom bands can be swapped with accessory bands,
sold separately on fitbit.com. For band measurements, see "Band size" on page51.
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.
