Customer feedback on How to sync Fitbit Charge 5

Good Unit… once last battery problem

Very long time Fitbit user and have had several Charge models. Was excited when this one came out and preordered. Setup was okay and no issues tho it did an update right away. I noticed that the battery was draining and could not keep a charge longer than 20 hours. After a few days of constant charging and trying all the forum suggestions, exchanged it for another. It setup easily (no update) but have been going for five days on the very first charge so I am sure it was defective battery. I’m on an iPhone XR and have had no issues with syncing or connecting for on phone GPS walks. Have not looked at the premium trial yet as I wanted to know what it was like standalone. Like the screen visibility so much more on walks now!

What is good in Fitbit Charge 5 – review & troubleshooting?


And while its predecessor sports a cheap plastic resin case, this year’s model is housed in aluminum, giving it a classier look. It doesn’t have any buttons, but features stainless steel panels on the sides that are flush with the case, serving as sensors for the ECG and EDA apps.

Supported band size

The small one fits wrists 5.1 to 6.7 inches in circumference; the larger one accommodates wrists up to 8.3 inches. The tracker and the silicone band are water resistant to 164 feet, so they’re safe to wear in the rain, pool, or at the beach.


On the design front, the Charge 5 measures 1.44 by 0.89 by 0.44 inches (LWD), making it the widest of Fitbit’s current fitness trackers. It has a bright, colorful 1.04-inch AMOLED touch screen, a major upgrade compared with the grayscale Charge 4. Moreover, the Charge 5 is Fitbit’s first fitness tracker with an always-on display option, a feature that comes in handy when you want to simply glance down at your wrist to check the time.


Since the Charge 5 has no physical buttons, you navigate it exclusively with swipes and taps on the screen. That’s a change from last year’s model, which featured a multi-function inductive button on the left side of the device. Navigation is still simple as the interface is well organized, with mostly white text and colorful accents set against a black background.

Health & activities feature

For fitness tracking, the Charge 5 features 20 exercise modes, SmartTrack automatic exercise recognition, Fitbit’s Active Zone Minutes metric, a GPS to map your route during outdoor exercises (like running, biking, and hiking), and in-app workout intensity maps showing your pace and heart rate zones throughout your route. To help you keep tabs on your ticker, it tracks your heart rate 24/7 and can alert you if it’s unusually high or low.

Even though the Charge 5 is significantly smaller than Fitbit’s smartwatches, it doesn’t skimp on sensors. Onboard is a heart rate tracker with high and low heart rate alerts; an electrocardiogram app that detects signs of atrial fibrillation; an SpO2 sensor for blood oxygen levels; plus skin temperature tracking at night (but no dedicated skin temperature sensor like on the Sense).

SmartTrack feature

Fitbit’sSmartTrackfeature automatically recognizes and records certain types of workouts, including walking, running, aerobic and elliptical sessions, outdoor cycling, continuous high-movement sports (like tennis, basketball, and soccer), and swimming. In testing, SmartTrack accurately logged several walks, but one time mislabeled a walk as a swim, a problem that also occurred once when I tested the Luxe. If this happens, you can manually re-categorize the exercise in the app.

Battery life

In terms of battery life, the Charge 5 promises to last up to a week on a charge, the same as its predecessor, which is impressive given its color display, bump in screen brightness, and slimmer design. Certain features significantly impact battery life, primarily GPS and the always-on display. Fitbit says the Charge 5 will last up to five hours while continuously tracking a workout with GPS, or up to two days with the always-on display turned on.

How to set up Fitbit Charge 5

1. Open the Fitbit app on your smartphone or tablet and log in. If you have just downloaded the app for the first time, you’ll need to set it up beforehand. It’ll ask for your name, age, height, and weight. You can go back and add these later, but it’s probably best to enter all your information now.

2. Select Set Up a Devicein the Fitbit app.

3. You should see Charge 5 appear from the list of Fitbit models. Once you see Fitbit Charge 5 flash up, select ‘set up’ to start the process.

4.Before anything else happens,accept the Fitbit Terms and Conditions. Have a quick scan through them, before clicking ‘I accept’ to move on to the next step.

5. You’ll then be prompted to connect your Fitbit Charge 5 to its magnetic chargerfor the rest of the setup. Once your app detects it is connected to the charger, it should automatically move on to the next step.

6. A four-digit code should flash up on the screen of the Fitbit Charge 5.The app will ask you to input this code. After that, you’ll need to accept the Bluetooth pairing request (make sure you have Bluetooth enabled on your phone beforehand).

7. At this stage, you might be prompted to update the software on your Fitbit.Select ‘Update Now’ and wait for your Fitbit to update. Even if you walk away at this step, be sure to leave your phone or tablet close to your Fitbit.

8.You’ll then go through some instructions on how to use, and wear your Fitbit. You can skip through these if you’re already familiar with the Charge model.

9.The last step is toset up Fitbit Premium. Your Fitbit Charge 5 includes a six-month premium trial, giving you time to explore the different features on offer without committing to a monthly fee.

10.Your Fitbit Charge 5 should now be ready to use. Enjoy!

What to do if GPS data does not sync Fitbit Charge 5?

Solution 1: Make sure the Fitbit Charge 5has clear view of the sky

The GPS signal of your watch is taken from the satellites above. It is therefore important that your watch has a clear view of the skies above.

Try to avoid tall buildings, dense forests, steep hills. Even a cloudy day can make obtaining a connection from GPS satellites more difficult.

Solution 2: Update the Fitbit Charge 5 software

There are instances when the watch GPS signal disconnects because of a software glitch. You should try checking if a new software update is available for the Charge 5 and update it accordingly.

Before performing any software update your tracker’s battery must be at least 20% charged. Updating Charge 5 may be demanding on the battery so its best to plug the tracker into the charger before starting an update.

Manually updating the Charge 5

If the Charge 5 is already running on the latest software update then you will get the message ” Charge 5 is up to date”.

Solution 3: Restart the Fitbit Charge 5

Sometimes this issue can be caused by a temporary software glitch that usually goes away if you restart the watch.

Solution 4: Factory reset the Fitbit Charge 5

Performing a factory reset will delete your data stored in the device and bring it back to its default settings.
