Customer Ratings & Reviews

Hi, there. We're sorry to hear that you're having difficulty turning off the water lock on your Fitbit Charge 6. We're always looking for ways to improve, and we appreciate your feedback. To turn off the water lock, firmly double-tap the middle of the screen with your finger. If you don't see "Unlocked" appear on screen, try tapping harder. Turning off this feature uses the Accelerometer in your device, which takes more force to activate. For more information, please visit this: https://support.google.com/fitbit/answer/14236707

Hi there, Kenneth. We hear your concerns regarding inconsistent heart rate tracking on the Charge 6 — we get how frustrating this is. Heart rate tracking accuracy is affected by your personal physiology, device placement on your arm, and the activity you're doing. Here’s a few tips to get better readings:

1. Wear your Fitbit device on top of your wrist with the back in contact with your skin. When not exercising, position it a finger's width above your wrist bone.
2. During exercise, wear it slightly tighter and higher for a snug fit that doesn't restrict blood flow, as this can affect the heart rate signal.
3. Frequent wrist bending during activities can also interfere with the signal if the watch is worn too low.

Regarding not getting SpO2 data, there could be a few things impacting the readings:

1. Turning off any SpO2 clock face or app permissions can cause the feature to stop functioning.
2. You must get at least 3 hours of quality sleep. Data is only collected when you’re still. If you move a lot during your sleep or the sleep session is too short, you might not get SpO2 data.
3. Charge your Fitbit device to make sure it’s able to collect data throughout your entire sleep session. Note that you may have to charge your Fitbit device more often when using an SpO2 clock face or app.
