25. Garmin Fenix 8 Rumors: AMOLED Screens and ECG Updates

The Garmin Fenix series has long been the gold standard for outdoor multisport watches. With the recent release of the Fenix 7 Pro and Epix Pro (Gen 2) in May 2023, the cycle of speculation for the Garmin Fenix 8 has already begun. Enthusiasts are eager to see if Garmin will finally merge its top-tier battery life with modern display technology. Below is a breakdown of the most credible rumors, expected features, and release timelines for the next generation of GPS wearable tech.

The Great Display Shift: AMOLED vs. MIP

The most significant rumor surrounding the Fenix 8 is the potential abandonment—or optional replacement—of the classic Memory-In-Pixel (MIP) display. Historically, Fenix watches used MIP screens because they are highly readable in direct sunlight and consume very little power. However, the market is shifting.

Garmin’s own Epix (Gen 2) series has proven that outdoor enthusiasts are willing to sacrifice a small amount of battery life for a bright, high-resolution AMOLED screen. The industry expectation is that the Fenix 8 will likely offer an AMOLED version as a standard option.

  • Visual Fidelity: An AMOLED screen would provide true blacks and vibrant colors, making topographical maps easier to read and on-screen workout animations much clearer.
  • The Solar Challenge: Integrating solar charging with AMOLED is technically difficult. Currently, Garmin’s solar tech works best with MIP screens. If the Fenix 8 goes full AMOLED, it might lose the “Solar” branding unless Garmin unveils a new breakthrough in through-display photovoltaic glass.
  • Battery Impact: A move to AMOLED would likely reduce battery life from the massive 28-day standard of the Fenix 7X to something closer to the 16-day range seen on the Epix Pro 51mm.

Health Tech: Elevate Gen 5 and ECG

The Fenix 8 is all but guaranteed to feature the Elevate Gen 5 optical heart rate sensor. This hardware is already present in the Fenix 7 Pro and Venu 3. It features more LEDs and a larger surface area for better accuracy during high-intensity interval training (HIIT) or weightlifting.

More importantly, this sensor hardware enables the FDA-cleared ECG (Electrocardiogram) app. This allows users to record their heart rhythm and check for signs of atrial fibrillation (AFib) directly from the wrist. While the Fenix 7 Pro currently has this hardware, it will be a native, headline feature for the Fenix 8 upon launch.

We also anticipate the addition of a skin temperature sensor. This sensor is currently used in competitors like the Apple Watch Ultra 2 for retrospective ovulation estimates and sleep analysis. Garmin could utilize this data to improve its “Body Battery” and recovery time metrics.

Smart Features: Microphone and Speaker Integration

For years, the Fenix line was strictly a “tool” watch rather than a “smartwatch.” That line is blurring. Following the success of the Garmin Venu 3, the Fenix 8 is expected to include a built-in microphone and speaker.

This hardware update would unlock several capabilities:

  • Phone Calls: Taking calls directly from the wrist when connected to a smartphone.
  • Voice Assistants: Accessing Siri, Google Assistant, or Samsung Bixby to send texts or ask questions mid-hike.
  • Audio Notes: The potential to record voice memos during a run or hike, which would be a massive utility for trail runners and navigators.

Design and Build Quality

Garmin rarely changes the rugged aesthetic that defines the series, so expect the Fenix 8 to maintain the five-button interface. The touchscreen introduced in the Fenix 7 will remain, likely with improved responsiveness.

  • Sizing: The three-size structure will likely persist: the 42mm (Fenix 8S), 47mm (Fenix 8), and 51mm (Fenix 8X).
  • Flashlight for All: The Fenix 7 Pro brought the built-in LED flashlight to all three sizes (previously it was only on the large “X” model). The Fenix 8 will undoubtedly keep this feature across all distinct sizes, as it has become a fan-favorite utility for safety and camping.

Release Date and Pricing

Garmin generally operates on an 18 to 24-month update cycle for its flagship devices.

  • Fenix 6: August 2019
  • Fenix 7: January 2022
  • Fenix 7 Pro: May 2023

Based on this cadence, a late 2024 or early 2025 release date is most probable for the Fenix 8.

Regarding price, inflation and component costs (especially if AMOLED becomes standard) suggest a price hike. The base Fenix 7 started at $699. It is reasonable to expect the Fenix 8 to start closer to $799 or $899, with Sapphire Solar models pushing well past the $1,100 mark.

Frequently Asked Questions

Will the Fenix 8 have LTE? Rumors regarding LTE are mixed. Garmin currently offers the “Bounce” for kids and the specialized “945 LTE,” but they have hesitated to put full LTE (calling/texting without a phone) into the Fenix line due to battery drain. It is more likely they will stick to safety tracking features rather than full standalone connectivity.

Should I wait for the Fenix 8 or buy the Fenix 7 Pro? If you need a watch now, the Fenix 7 Pro is an exceptional device that will remain relevant for years. If you specifically want an AMOLED screen with a rugged build, you should look at the Garmin Epix Pro (Gen 2) today rather than waiting for the Fenix 8.

Will the Fenix 8 use the same charging cable? Garmin has used its proprietary four-pin connector for years. However, with the EU mandating USB-C for many devices, Garmin may introduce a magnetic wireless charging puck similar to the “Marq” series to improve water resistance and charging reliability, though this remains unconfirmed.
