Fitbit Charge 6 vs Inspire 3: Price

First up, there’s a noticeable price difference between the Charge 6 and Inspire 3 models. The Charge 6 costs $160, while the Inspire 3 is just $100. So if budget is your top concern, the Inspire 3 gives you solid fitness tracking fundamentals and sleep monitoring at an affordable price point.

The Charge 6 fits into that mid-range wearable category, costing more but adding extra features like built-in GPS, additional health sensors, and new integration with Google services.

The Fitbit Charge 6 comes in three case colours: Obsidian, Porcelain, and Rose Gold, with different band options for an additional cost. While the Inspire 3 only has a black colour option but has interchangeable bands,

Design and Display

Let’s dive into the design and build of both of these watches.

From an aesthetic point of view, the Inspire 3 has a slim, lightweight design of Fitbit’s Luxe tracker. The watch’s narrow plastic body feels comfy on the wrist, similar to older-generation trackers.

On the other hand, the Charge 6 has a more premium look with its aluminium alloy casing and interchangeable band options for a flush, versatile fit. It’s also larger than the Inspire 3 but still lightweight for comfortable all-day wear.

For displays, the Charge 6 wins on size and quality with its bright and crisp 1.04” AMOLED touchscreen versus the Inspire 3’s 1.4” display. But both deliver excellent graphics and responsiveness. The Inspire 3 relies on touch buttons, while the Charge 6 brings back a physical side button for easier control during activities.

Both bands do have Corning Gorilla Glass to protect your screen, so you don’t have to worry about cracks and chips while you are hiking or biking.

Health and Fitness Tracking

When it comes to activity and health monitoring, both trackers cover the basics like steps, distance, calories burned, and heart rate monitoring. The Inspire 3 also impresses with its detailed sleep metrics and blood oxygen monitoring. The companion app helps users make sense of their data.

But the Charge 6 pulls ahead with its wide range of sensors, including a built-in GPS for tracking outdoor activity, meaning you don’t need your phone when you are hiking. The Inspire 3 does not have a built-in GPS, but it does use your phone’s GPS, so if you are a fan of GPS for your adventurous activities, then the Charge 6 will be a better option for you.

The Charge 6 has ECG sensors to check for heart rhythm irregularities to detect a potential sign of aFib, EDA for stress level insights, and SpO2 overnight. The Charge 6 also enables sharing real-time heart rate with compatible gym equipment.

The Inspire 3 can notify you of irregular heart rate rhythms but does not have an ECG for more data, and features like EDA are also not present here.

So for users focused on athletic performance, heart health metrics, and comprehensive tracking, the Charge 6 provides the best health tracking capabilities. But the Inspire 3 still delivers excellent functionality for its affordable cost.


In terms of smart features, the Inspire 3 handles basic notifications well, allowing users to stay updated on calls, texts, and social media happenings. However, you can’t actively respond to or take action on notifications from the Inspire 3’s display.

The Charge 6 introduces Google integration to Fitbit’s lineup with apps like Google Maps for turn-by-turn directions on the wrist and Google Wallet for contactless payments. These can be handy for tracking outdoor activity or when your phone isn’t handy. The Charge 6 also enables control of YouTube music playback.

Battery Life and Durability

If we talk about battery life, the Inspire 3 manages an impressive 10 days between charges. The Charge 6, meanwhile, promises approximately 7 days of battery life—still decent but defeated by the cheaper Inspire 3. Both charge back up in around 2 hours.

In terms of durability, the two Fitbit models have similar water resistance up to 50 metres deep. So wearing them while swimming or in the shower is fine.


The Inspire 3 and Charge 6 offer some core functionalities like activity tracking, heart rate monitoring, and sleep analysis. But they excel in different areas at different price points.

The Inspire 3 best suits users looking for a comfortable, long-lasting tracker with essential health and fitness functions. Its budget-friendly cost makes it very accessible while still offering Fitbit’s quality software and app experience.

The Charge 6 is for more committed athletes and health-focused users who want metrics like GPS, heart rhythm data, and stress management insights. So it ultimately comes down to your budget and which advanced features are most important to you.
