Summary:

  1. Year-Long Test Results
    A year-long experiment with the iPhone 15 Pro Max’s 80% charge limit feature showed only slight improvements in battery health, maintaining 94% capacity after 299 charge cycles.

  2. Comparison with Standard Charging
    In contrast, iPhones without this charge limit retained about 87-90% capacity. The feature aims to extend battery life by restricting maximum charge levels.

  3. User Experience Challenges
    The tester, Juli Clover, noted occasional inconveniences, such as battery depletion during long days. While the battery health showed some retention, the daily usability trade-off was questioned.

  4. Skepticism About Trade-Offs
    Clover observed only a 4% difference in battery capacity after a year and expressed uncertainty about whether the limitations were worth the minor benefits. She speculated that significant gains might only become apparent over two to three years.

  5. Future Considerations
    Clover plans to continue using the 80% charge limit to assess its long-term effects on battery performance.
