Meet Fitbit Charge 5, our most advanced health and fitness tracker that helps you
keep a pulse on your stress, physical readiness, heart health, and overall well-being.
Take a moment to review our complete safety information at fitbit.com/safety.
Charge 5 is not intended to provide medical or scientific data.
What's in the box
Your Charge 5 box includes:
Tracker with small band
(color and material varies)
The detachable bands on Charge 5 come in a variety of colors and materials, sold
separately.
Charging cableAdditional large band
6
Charge your tracker
A fully-charged Charge 5 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 5:
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 5 charges, double-tap the screen
to turn it on and check the battery level. Swipe right on the battery screen to use
Charge 5. A fully charged tracker shows a solid battery icon.
7
Set up Charge 5
Set up Charge 5 with the Fitbit app. The Fitbit app is compatible with most popular
phones. See fitbit.com/devices to check if your phone is compatible.
To get started:
1. Download the Fitbit app:
l Apple App Store for iPhones
l Google Play Store for Android phones
2. Install the app, and open it.

Wear Charge 5
WearCharge 5 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 5 a finger's width above your wrist bone.
In general, it's always important to give your wrist a break on a regular basis 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:
l 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.
10
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).
Note: If you have trouble connecting to GPS on Charge 5, see the related help
article.
Fasten the band
1. Place Charge 5 around your wrist.
2. Slide the bottom band through the first loop in the top band.
11
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.
Handedness
For greater accuracy, you must specify whether you wear Charge 5 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 5
on your dominant hand, change the Wrist setting in the Fitbit app:
From the Today tab
Wrist Dominant.
in the Fitbit app, tap your profile picture Charge 5 tile
12
Wear and care tips
l Clean your band and wrist regularly with a soap-free cleanser.
l If your tracker gets wet, remove and dry it completely after your activity.
l Take your tracker off from time to time.
For more information, visit the Fitbit Wear & Care page.
Change the band
Charge 5 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 page54.
Remove a band
1. Turn over Charge 5 and find the band latches.
2. To release the latch, use your fingernail to press the flat button toward the
band.
13
3. Gently pull the band away from the tracker to release it.
4. Repeat on the other side.
Attach a band
To attach a band, press it into the end of the tracker until you hear a click and it
snaps into place. The band with the loops and peg attaches to the top of the
tracker.

Check your workout summary
After you complete a workout, Charge 5 shows a summary of your stats.
Check the Exercise tile in the Fitbit app to see additional stats and a workout
intensity map if you used GPS.
Check your heart rate
Charge 5 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 5 notifies you when you
enter a heart-rate zone.

Custom heart-rate zones
Instead of using these heart-rate zones, you can create a custom zone in the Fitbit
app to target a specific heart-rate range.
For more information, see the related help article.
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.
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 5 notifies you about Active Zone Minutes:
l A few moments after you enter a different heart-rate zone during your
exercise using the Exercise app
working. The number of times your tracker vibrates indicates which zone
you’re in:
1 buzz = fat burn zone
2 buzzes = cardio zone
3 buzzes = peak zone

during a brisk walk).

Troubleshooting
If Charge 5 isn't working properly, see our troubleshooting steps below.
Heart-rate signal missing
Charge 5 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
your tracker correctly, either by moving it higher or lower on your wrist or by
tightening or loosening the band. Charge 5 should be in contact with your skin.
After holding your arm still and straight for a short time, you should see your heart

the related help article.
on your tracker. Next, make sure you're wearing
GPS signal missing
Environmental factors including tall buildings, dense forest, 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 “
GPSconnecting
50
” appear at the top of the screen. If Charge 5 can't connect to a GPSsatellite,
the tracker stops trying to connect until the next time you start a GPSexercise.
For best results, wait for Charge 5 to find the signal before you start your workout.
If you still have trouble connecting to GPS or notice that your distance traveled
seems inaccurate, try the following tips to allow your device to connect to GPS
satellites:
l Follow the recommendations for wearing your device for exercise. For more
information, see "Wear Charge 5" on page10.
l Try loosening the band 1 notch.
l Make sure your device doesn't touch your wrist bone.
l Avoid bending your wrist backwards.
l To more quickly establish a GPS connection, point your device toward open
sky (clear of heavy tree coverage and away from tall buildings).
l Establish a GPS connection before beginning your exercise.
l Hold your arm parallel to your body near your head and at least 2 inches away.
