The latest update to the Zepp app, version 9.5, has left many Amazfit smartwatch users frustrated and concerned about the accuracy of their fitness tracking.

The Exertion Score Bug

What is the Exertion Score?

The Exertion score is a relatively new feature introduced with Zepp App 9, designed to help users track their daily energy expenditure. This metric aims to provide a comprehensive view of a user's physical activity and recovery, encouraging them to reach a 100% score through workouts. The score is calculated using personal recovery data and Readiness information, offering a personalized goal for each user.

The Problem

Following the Zepp App 9.5 update, users have reported significant issues with their Exertion scores. The problems include:

  • Scores not reflecting recent workouts
  • Exertion scores resetting to 0 after activities
  • Unexpected drops in progress despite consistent exercise

These issues are not isolated to a single Amazfit model but have been reported across various devices, including the popular Bip 3 Pro and T-Rex 3 smartwatches.

Impact on Other Metrics

Training Status

Users have also reported issues with their Training Status, which helps athletes understand their fitness level and recovery needs. Inaccurate data could lead to improper training decisions, potentially affecting performance and increasing the risk of overtraining or undertraining.

Personal Activity Intelligence (PAI)

The PAI metric, developed in collaboration with researchers from the Norwegian University of Science and Technology, is also affected. Users are not receiving accurate PAI scores, undermining their fitness tracking efforts.

Possible Causes

  • Data synchronization issues between the smartwatch and the Zepp app
  • Errors in the algorithm calculating the Exertion score and related metrics
  • Conflicts with other recent updates or features introduced in version 9.5
