The June 2026 COROS firmware update introduces automated heart rate recovery tracking, a battery health monitoring page, and native AllTrails integration across its wearable lineup. According to official release documentation, these features aim to provide deeper physiological insights and streamlined navigation for endurance athletes. The update is rolling out globally to iOS and Android users, with firmware deployment expected to complete by late June 2026.
How does COROS track heart rate recovery?
COROS now automatically logs heart rate recovery after every tracked activity, measuring the decline in beats per minute over a two-minute window. For interval training, the watch logs recovery between individual rest periods and displays this data directly within the lap table. This allows athletes to observe performance trends as a session progresses, rather than relying solely on a post-workout summary.
While Garmin has long utilized heart rate recovery as a component of its training readiness scoring, the COROS implementation prioritizes granular, per-interval visibility. This feature is currently available on the PACE 4, PACE Pro, PACE 3, APEX 4, APEX 2, APEX 2 Pro, NOMAD, VERTIX 2, and VERTIX 2S.
What is the purpose of the new Battery Health page?
The Battery Health page addresses long-term hardware concerns by visualizing power consumption trends over the previous seven-day period. According to COROS, this tool helps users identify if specific settings or background processes are causing faster-than-expected battery drain. The system now provides an automated warning banner if it detects unusual power usage, removing the guesswork previously associated with declining battery life.
Like the recovery tracking feature, the Battery Health page is supported on the PACE 4, PACE Pro, PACE 3, APEX 4, APEX 2, APEX 2 Pro, NOMAD, VERTIX 2, and VERTIX 2S.
How does the AllTrails integration work?
The AllTrails update enables bidirectional communication between the app and COROS devices. Users can sync routes directly to their watch for navigation, while completed activities are pushed automatically back to the AllTrails platform. This integration is the most widely available feature in the update, extending to older hardware including the PACE 2, APEX Pro, VERTIX 1, APEX 42/46mm, and the DURA bike computer.
Direct route synchronization requires an AllTrails Plus or Peak membership, which cost approximately $36 and $80 per year, respectively. Users on the free AllTrails tier retain the ability to manually export GPX files and import them via the COROS app, a workflow that remains unchanged by this update.

FAQ
Which COROS watches track heart rate recovery?
The feature is available on the PACE 4, PACE Pro, PACE 3, APEX 4, APEX 2, APEX 2 Pro, NOMAD, VERTIX 2, and VERTIX 2S. Older models like the PACE 2 and VERTIX 1 do not support this specific metric.
Is a paid subscription required for AllTrails integration?
Direct sync requires an AllTrails Plus or Peak membership. Free users can still import routes manually using GPX files.
What does the Battery Health page monitor?
It tracks power consumption and usage trends over seven days and triggers an alert if it detects abnormal battery drain.
