Fitbit has long been a dominant force in the fitness tracker market, consistently pushing the boundaries of what wearable technology can offer. The Fitbit Charge 4 was an impressive device when it launched, providing built-in GPS, heart rate tracking, and sleep monitoring. However, the Fitbit Charge 5 has arrived with significant upgrades that make it an even more attractive option for fitness enthusiasts. This comparison will highlight key differences and help determine whether upgrading from the Charge 4 to the Charge 5 is worthwhile.

One of the most noticeable upgrades in the Fitbit Charge 5 is the introduction of a full-color AMOLED display, replacing the monochrome screen found on the Fitbit Charge 4. This upgrade enhances visibility, making it easier to read notifications, track fitness stats, and customize watch faces. The touchscreen responsiveness has also improved, providing a smoother navigation experience. While the Fitbit Charge 4 was a solid device, its screen felt outdated compared to the vibrant display of newer models like the Fitbit Sense 2 and Fitbit Versa 4.

Another major difference between the two models is the inclusion of the EDA (Electrodermal Activity) sensor in the Fitbit Charge 5, a feature previously seen in premium models like the Fitbit Sense. This sensor helps users track stress levels and provides guided breathing exercises to improve mental well-being. The Fitbit Charge 4 lacks this feature, making the Charge 5 a better option for those who prioritize stress management alongside fitness tracking.

Battery life remains a strong point for both devices, with the Fitbit Charge 5 offering up to seven days of usage on a single charge, similar to its predecessor. However, the introduction of the always-on display mode slightly reduces battery efficiency when activated. Fitbit Watch for women and Fitbit Watch for men users who prefer long-lasting performance will appreciate the balance of battery life and functionality in the Charge 5.

The Fitbit Charge 5 also includes Daily Readiness Score, a feature that helps users determine their optimal workout intensity based on previous activity, sleep, and heart rate variability. This feature is absent in the Fitbit Charge 4, making the newer model more appealing for those who rely on data-driven fitness insights. Although models like the Fitbit Versa 3 and Fitbit Inspire 3 offer some similar tracking capabilities, the Charge 5 delivers them in a compact, fitness-focused design.

In terms of design, the Fitbit Charge 5 sports a more refined and modern look compared to the bulkier, angular Fitbit Charge 4. The smooth, streamlined edges of the newer model make it more comfortable to wear throughout the day. Additionally, the Charge 5 ditches physical buttons in favor of a fully touch-based interface, aligning it with premium Fitbit models such as the Fitbit Luxe and Fitbit Inspire 2.

While both devices offer excellent fitness tracking features, the Fitbit Charge 5 undoubtedly provides a more comprehensive experience, incorporating advanced sensors, a better display, and a more polished design. Users looking for an affordable entry into Fitbit's ecosystem might still find value in the Charge 4, but for those seeking the best balance of price and features, the Fitbit Charge 5 is the superior choice.
