Repair Windows errors before they cause bigger problemsFix Now →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →DND means “Do Not Disturb.” On a Fitbit, it is a quiet mode that suppresses ordinary interruptions such as mirrored phone notifications, goal celebrations, reminders to move and, on supported models, heart-zone alerts. The device may still receive or record information, but it normally will not vibrate or wake the screen for those events. The exact alert categories depend on the model and software.
The DND icon generally means the setting is enabled. It is not a fault warning, a battery-saving mode or a switch that stops Fitbit health and activity tracking. Start by identifying your Fitbit model, because the controls and gestures differ substantially between generations.
What DND silences—and what it does not
Fitbit describes DND as an alert-suppression setting. Commonly muted events include:
- Phone notifications mirrored to the Fitbit
- Goal celebrations
- Reminders to move
- Heart-zone or Active Zone Minutes alerts on applicable devices
- The vibration and screen wake associated with those events
These are alerting changes, not a general shutdown of tracking. Fitbit does not promise identical behavior for every model, and alarms are handled as a separate feature. Check your device’s alarm support before assuming an alarm will or will not sound while DND is active (Fitbit alarm guidance).

Charge 3 and Charge 4 have a documented exception: an Exercise alerts setting can allow workout alerts during DND. Do not treat that exception as a rule for every Fitbit (Fitbit alert troubleshooting).
DND versus Sleep Mode
| Behavior | DND | Sleep Mode |
|---|---|---|
| Mutes notifications | Yes | Yes |
| Mutes goal celebrations and movement reminders | Commonly | Commonly |
| Dims the display | Not its defining behavior | Yes |
| Prevents wrist-turn screen wake | Not generally | Yes |
| Turns off always-on display | Not generally | On supported watches |
| Scheduling | Model-dependent | Available on many newer devices |
| Can run with the other mode | No on documented devices | No on documented devices |
Choose DND for a meeting, commute or workout when you want alerts muted but normal screen behavior. Choose Sleep Mode when you also want a dim display, no wrist-raise wake and, where supported, an automatic schedule. Labels and behavior vary by Fitbit generation (Google Health navigation guide).
How to turn DND on or off by Fitbit model
Check the model name in the Fitbit or Google Health app before following a path. A “swipe down” instruction is not correct for every Fitbit.
Charge 5 and Charge 6
- From the clock screen, swipe down to open Quick Settings.
- Tap DND. The icon illuminates when it is on; tap it again to turn it off.
Inspire 3
- Swipe down from the clock screen to Quick Settings.
- Tap the DND icon. Check Sleep Mode separately if notifications remain silent.
Luxe
- Swipe down from the clock screen.
- Tap DND mode. The icon should no longer be illuminated when alerts are restored.
Luxe’s manual distinguishes DND from Sleep Mode, and the two modes cannot be enabled together (Luxe User Manual).

Charge 3
Charge 3 uses older controls. Fitbit’s notification instructions refer to Notifications During Sleep in the Settings app rather than the newer Quick Settings flow. Use the model-specific steps in Fitbit’s notification guide.

- Tap the DND icon.

Inspire and Inspire HR
These first-generation models use a notification control rather than the DND control found on newer devices:
- Press and hold the button.
- Tap Notifications to toggle notification delivery.
For model-specific paths, consult Change phone notifications on my Fitbit device.
How to tell which quiet mode is active
Open Quick Settings or the notification/status panel. An illuminated DND icon normally means DND is on; a dimmed icon generally means it is off. A dim display, disabled wrist-turn wake or a scheduled shutoff points more strongly to Sleep Mode. Icon placement and appearance can change with model and firmware.
Scheduling Sleep Mode
Where scheduling is supported:
- Open Settings.
- Choose Sleep Mode, or Quiet Modes → Sleep Mode.
- Enable scheduling.
- Set the start and end time, then save.
A scheduled Sleep Mode can switch off automatically even if you enabled it manually earlier. Fitbit documents scheduling more consistently for Sleep Mode than for DND; do not assume every model offers a DND schedule (Google Health navigation guide).

Fitbit DND and phone DND are separate
Fitbit DND is a setting on the wearable. Android or iPhone Do Not Disturb, Driving Mode and similar phone modes are controlled by the phone’s operating system. A phone may receive a notification while its active mode prevents the Fitbit from alerting you. Conversely, Fitbit DND can mute the wearable while the phone continues to alert normally.
If the phone is receiving alerts but the Fitbit is silent, check both sides:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Turn off DND on the Fitbit.
- Turn off Fitbit Sleep Mode.
- Check phone Do Not Disturb, Driving or Bedtime modes.
- Review Fitbit notification permissions and the affected app’s permission.
- Sync the device, then restart it if the displayed state appears stale.
Android and iOS handle notification permissions and background delivery differently. Fitbit provides separate operating-system guidance in its Android instructions and iPhone and iPad instructions.
When your Fitbit stops vibrating or showing alerts
Use this order so you do not mistake a quiet mode for a connection failure:
- Confirm Fitbit DND is off.
- Confirm Sleep Mode is off and no schedule is currently active.
- Check vibration strength in device settings.
- Verify that the event is an alert your model supports.
- Check phone permissions and Fitbit notification settings.
- Confirm Bluetooth connection and complete a sync.
- Restart the Fitbit.
- If only one app is affected, repair that app’s notification permission.
- Contact Fitbit or Google Health support if all supported alerts still fail.
If notifications appear but are silent
A notification that is visible on the Fitbit but produces no vibration usually points to DND, Sleep Mode, phone-level DND or vibration settings. A notification that never reaches the Fitbit requires checking permissions, supported apps and the connection.

If DND keeps turning on
Look for scheduled Sleep Mode first. Also check whether you are tapping Quick Settings accidentally, whether a phone-level mode is active or whether the device needs a sync or restart. Fitbit does not document one universal automatic DND schedule.
If DND cannot be enabled
Sleep Mode may already be active. Turn Sleep Mode off, then enable DND; the two modes cannot run simultaneously on documented devices.
If workout alerts continue during DND
On Charge 3 and Charge 4, check Exercise alerts. That model-specific option can intentionally permit workout alerts during DND.
If alarms do not sound
Check whether the alarm is enabled, whether it was created on the device or in the app, the battery level and whether your model supports on-device alarms. Alarm behavior is model-specific; some Versa models have documented low-battery limitations. Use Fitbit’s alarm guidance rather than assuming DND is responsible.

Frequently Asked Questions
Does DND stop Fitbit from tracking sleep or activity?
DND is documented as an alert-suppression setting. It does not represent a general shutdown of health or activity tracking, although exact device behavior can vary.
Does DND block every alarm?
Not necessarily. Alarms are a separate, model-specific feature, so check your device’s alarm documentation and battery requirements.
Can DND and Sleep Mode be on together?
On documented Fitbit devices, they cannot be active simultaneously. Turn one off before enabling the other.
Why is my Fitbit silent while my phone is not?
Check Fitbit DND and Sleep Mode first, then phone notification permissions and any phone-level DND or Driving mode.
Does Fitbit DND turn off automatically?
Automatic shutoff is more consistently documented for scheduled Sleep Mode. DND scheduling and behavior vary by model.
