Charge 5 is not intended to provide medical or scientific data.

What's in the box

Your Charge 5 box includes:

The detachable bands on Charge 5 come in a variety of colors and materials, sold separately.

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.

Set up Charge 5

Set up Charge 5 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.

To get started:

1. Download the Fitbit app:

• Apple App Store for iPhones

Wear Charge 5

Wear Charge 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".

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:

• 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 heartrate 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).

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.
   
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 in the Fitbit app, tap the icon in the top left → Charge 5 tile → Wrist →Dominant.

Wear and care tips

• Clean your band and wrist regularly with a soap-free cleanser.
• If your tracker gets wet, remove and dry it completely after your activity.
• 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. Both the top and bottom bands can be swapped with accessory bands, sold separately on fitbit.com. For band measurements, see "Band size".

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.
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.

Icon	Zone	Calculation	Description
	Below Zone	Below 40% of your heart rate reserve	Below the fat burn zone, your heart beats at a slower pace.
	Fat Burn Zone	Between 40% and 59% of your heart rate reserve	In the fat burn zone, you're likely in a moderate activity such as a brisk walk. Your heart rate and breathing might be elevated, but you can still carry on a conversation.
	Cardio Zone	Between 60% and 84% of your heart rate reserve	In the cardio zone, you're likely doing a vigorous activity such as running or spinning.
	Peak Zone	Greater than 85% of your heart rate reserve	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 heart-rate zones, you can create a custom zone in the Fitbit app to target a specific heart-rate range.

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:

• A few moments after you enter a different heart-rate zone during your exercise using the Exercise app, so that you know how hard you're working. The number of times your tracker vibrates indicates which zone you're in:
  
  • 1buzz = fat burn zone
  • 2buzzes = cardio zone
  • 3 buzzes = peak zone
• 7 minutes after you enter a heart-rate zone throughout the day (for example, during a brisk walk).
  

To start, your weekly goal is set to 150 Active Zone Minutes. You'll receive notifications as you reach your goal.

Receive heart-rate notifications

Stay informed when Charge 5 detects that your heart rate is outside of your high or low thresholds when you appear to be inactive for at least 10 minutes.

To turn this feature off or adjust the thresholds:

1. From the Today tab in the Fitbit app on your phone, tap the icon in the top left → Charge 5 tile.
2. Tap High & low heart rate.
3. Turn High heart rate notification or Low heart rate notification on or off, or tap Custom to adjust the threshold.

View past heart-rate notifications, log possible symptoms and causes, or delete notifications in the Fitbit app.

Check your daily readiness score

Understand what's best for your body with the daily readiness score, available with a Fitbit Premium subscription. Your score ranges from 1 to 100, based on your activity, sleep, and heart-rate variability. A high score means you're ready to exercise, while a low score suggests you should focus on recovery.

When you check your score, you also see a breakdown of what impacted your score, a personalized activity goal for the day, and recommended workouts or recovery sessions.

Wear your tracker for a full day (at least 14 hours), including to sleep at night, and then swipe up from the clock face to find your readiness score in your daily stats.

We're always adding new locations and card issuers to our list of partners. To see if your payment card works on your Fitbit device, see:

• Fitbit Pay: fitbit.com/fitbit-pay/banks

Set up contactless payments

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

1. From the Today tab in the Fitbit app, tap the icon in the top left → Charge 5 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.

Make purchases

Note: To make contactless payments with Charge 5 in Australia and New Zealand, follow the instructions below for all card types. If prompted to enter a PIN code, enter your 4-digit tracker PIN code (not the PIN code for your card).

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

All customers, including those in Australia and New Zealand:

1. Swipe down from the clock face and tap Payments .
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, swipe to find the card you want to use, and hold your wrist near the payment terminal.

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

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

For added security, you must wear Charge 5 on your wrist to use contactless payments.

Change your default card

1. From the Today tab in the Fitbit app, tap the icon in the top left → Charge 5 tile.
2. Tap the Wallet tile.
3. Find the card you want to set as the default option.
4. Tap Set as Default on Charge 5.

Pay for transit

Use contactless payments to tap on and off at transit readers that accept contactless credit or debit card payments. To pay with your tracker, follow the steps listed in "Use credit and debit cards".

Pay with the same card on your Fitbit tracker when you tap the transit reader at the start and end of your trip. Make sure your device is charged before beginning your trip.

Update, Restart, and Erase

Some troubleshooting steps may require you to restart your tracker, while erasing it is useful if you want to give Charge 5 to another person. Update your tracker to receive the latest firmware.

Update Charge 5

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

When an update is available, a notification appears in the Fitbit app. After you start the update, follow the progress bars on Charge 5 and in the Fitbit app until the update is complete. Keep your tracker and phone close to each other during the update.

To update Charge 5, your tracker's battery must be at least 20% charged. Updating Charge 5 may be demanding on the battery. We recommend plugging your tracker into the charger before starting an update.

Restart Charge 5

If you can't sync Charge 5 or you have trouble with tracking your stats or receiving notifications, restart your tracker from your wrist:

1. Swipe down from the clock screen to find the Settings app .
2. Open the Settings app → Restart Device→ Restart.

If Charge 5 is unresponsive:

1. Connect your device to the charging cable. For instructions, see How do I charge my Fitbit device?
2. Press the button located on the flat end of the charger 3 times within 8 seconds, holding each press for about 1 second.
   
3. Wait 10 seconds or until the Fitbit logo appears.

Note: If the device doesn't restart, wait 15 seconds to try again.

Restarting your tracker doesn't delete any data.

Erase Charge 5

If you want to give Charge 5 to another person or wish to return it, first clear your personal data:

1. Swipe down from the clock screen to find the Settings app .
2. Open the Settings app → Device Info→ Clear User Data.
3. Swipe up, then press Hold 3 Sec for 3 seconds and release.
4. When you see the Fitbit logo and Charge 5 vibrates, your data is erased.

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 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 5 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 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 "GPS connecting " appear at the top of the screen. If Charge 5 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 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:

• Follow the recommendations for wearing your device for exercise. For more information, see "Wear Charge 5".
• Try loosening the band 1 notch.
• Make sure your device doesn't touch your wrist bone.
• Avoid bending your wrist backwards.
• To more quickly establish a GPS connection, point your device toward open sky (clear of heavy tree coverage and away from tall buildings).
• Establish a GPS connection before beginning your exercise.
  
• Hold your arm parallel to your body near your head and at least 2 inches away.
  

Other issues

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

• Won't sync
• Won't respond to taps or swipes
• Won't track steps or other data
• Won't show notifications

For instructions, see "Restart Charge 5".
