Comparison between Fitbit Charge 5 and Fitbit Inspire 3

Basically, the Fitbit Inspire 3 remains the cheaper fitness tracker in the comparison.


Both fitness trackers are built in a slim design. However, the Fitbit Inspire 3 is still somewhat narrower and slimmer than the Fitbit Charge 5 in comparison.


In a direct comparison, the Fitbit Charge 5 is technically better equipped and comes with more sensors:
  • Fitbit Charge 5: HR sensor, SpO2, GPS, NFC, EDA, ECG
  • Fitbit Inspire 3: HR sensor, SpO2

A heart rate (HR) sensor is now standard with Fitbit. Fitness trackers without Pulssensore also make little sense in my eyes. Also, the monitoring of blood oxygen can both the Charge 5, as well as the Inspire 3 via the SpO2 sensor.

A big difference lies in the GPS. Only in the Fitbit Charge 5 is GPS built. Thus, you can use the GPS function on the fitness tracker even without a smartphone. The situation is different with the Fitbit Inspire 3. Here you have to use connected GPS. This uses the GPS from the smartphone.

Through NFC is Fitbit Pay enabled. Means you can pay directly contactless with your fitness tracker. This is only possible with the Fitbit Charge 5.

Another advantage of the Fitbit Charge 5 lies in the EDA and EKG. Thus, the fitness tracker can realize stress management and output an assessment of heart rhythm. Thus, the heart rate is permanently monitored for irregularities.

Battery Life

Battery life is of course also an exciting topic in the comparison of the two fitness trackers Charge 5 and Inspire 3:
  • Fitbit Charge 5: 7 days
  • Fitbit Inspire 3: 10 days

Here, the Fitbit Inspire 3 beats the Charge 5 by 3 days. Depending on the use, the battery life decreases of course. Besodners the integrated GPS at the Charge 5 can reduce the battery life arg during use.

Fitness functions

In terms of functions, the two fitness trackers hardly differ. Both can the standards, which a fitness tracker should be able to: Activity tracking, sleep tracking, smartphone notifications.

The Fitbit Charge 4 still had the advantage that this had an altimeter installed and could thus count floors. With the Charge 5, however, this altimeter has disappeared: Fitbit Charge 4 vs Charge 5. Therefore, the Charge 5 and the Inspire 3 both can no longer count floors.

Which Fitbit fitness tracker is better?

In comparison, the Fitbit Charge 5 offers more. You get built-in GPS, Fitbit Pay and ECG as well as EDA. In terms of functionality, the fitness trackers are almost the same. If you do not need Fitbit Pay, built-in GPS, ECG or EDA, the Fitbit Inspire 3 offers a better price-performance ratio with a longer battery life. In addition, the Inspire 3 is somewhat more elegant in terms of design.
