Main summary

Key takeaways

Product Review

Product reviewed

  • iPhone Pro Max line battery health over yearly use, specifically:
    • iPhone 15 Pro Max → iPhone 16 Pro Max → iPhone 17 Pro Max
    • The 17 Pro Max is still nearing its 1-year mark.

Key features/settings mentioned (common across devices)

  • Charging limit set to 90%
  • Optimized Battery Charging enabled
  • Clean Energy Charging enabled
  • Consistent usage pattern (implied): installs betas and upgrades to the latest iOS each year.

Battery health results (after ~1 year of use)

iPhone 15 Pro Max

  • Maximum capacity: 86%
  • Charging cycles: 554

iPhone 16 Pro Max

  • Maximum capacity: 93%
  • Charging cycles: 493
  • Interpretation by speaker: suggests software fixes and/or improved battery technology improved retention.

iPhone 17 Pro Max** (nearly 1 year; projection + current near-comparable level)

  • Maximum capacity: 94% with 351 charging cycles (as of the ~1-year point)
  • Projection: likely to finish around 93–92% by next September (roughly a full year).

Pros (as concluded from the data)

  • Strong battery longevity on 16 Pro Max and 17 Pro Max: ~93–94% after one year
  • Big improvement from 15 → 16, indicating meaningful Apple changes in battery health handling (hardware/software integration)
  • 17 Pro Max appears on track to stay very close to 16 Pro Max performance

Cons / limitations mentioned

  • 17 Pro Max isn’t yet a full year old, so the final number is projected
  • Results depend on having the same iPhone settings (90% limit + optimization + clean energy); results may differ for others.

Comparisons made

  • 15 Pro Max vs 16 Pro Max: major jump in maximum capacity (86% → 93%) after ~1 year
  • 16 Pro Max vs 17 Pro Max: minimal difference so far (93–94%), expected to land around 93–92% at one year

User experience / takeaway

  • The speaker says the battery health differences are noticeable, especially the 15 → 16 leap.
  • Overall takeaway: battery health is “holding up pretty good” and consistent with last year’s devices, with improvements over the earlier model.
