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.Fitbit Charge 4 Fitness and Activity Tracker User Manual - Placement for all-day wear vs

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).

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 Fitbit Charge 4 Fitness and Activity Tracker User Manual - Fitbit app in the Fitbit app, tap your profile picture > Charge 4 tile > Wrist > Dominant.

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.Fitbit Charge 4 Fitness and Activity Tracker User Manual - To release the latch
  3. Gently pull the band away from the tracker to release it.Fitbit Charge 4 Fitness and Activity Tracker User Manual - Gently pull the band away from the tracker to release it

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.

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:Fitbit Charge 4 Fitness and Activity Tracker User Manual - Make purchases

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.

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

For more information, see help.fitbit.com.

Change your default card
  1. From the Today tab Fitbit Charge 4 Fitness and Activity Tracker User Manual - Fitbit app in the Fitbit app, tap your profile picture > Charge 4 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 4.

Pay for transit

Use Fitbit Pay 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” on page 43.

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

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 Fitbit Charge 4 Fitness and Activity Tracker User Manual - Settings app and tap About > Reboot Device.

If Charge 4 is unresponsive:

  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:

  1. On Charge 4, open the Settings app Fitbit Charge 4 Fitness and Activity Tracker User Manual - Settings app> About > Clear User Data.
  2. Swipe up, and tap the check mark icon to erase your data.

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.Fitbit Charge 4 Fitness and Activity Tracker User Manual - Heart-rate signal missing

If your tracker doesn’t detect a heart-rate signal, first make sure heart-rate tracking is turned on in the Settings app Fitbit Charge 4 Fitness and Activity Tracker User Manual - 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 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 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 “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.Fitbit Charge 4 Fitness and Activity Tracker User Manual - For best results

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

For more information, see help.fitbit.com.

Other issues

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

  • Won’t sync
  • Won’t respond to taps, swipes, or button press
  • Won’t track steps or other data

For instructions, see “Restart Charge 4” on page 46.
