Battery health is one of the first things a buyer or trade-in shop checks when you bring in an iPhone. Here's exactly how to find it, what the numbers mean, and how much it actually affects what you'll be paid.
That percentage tells you how much charge your battery can hold compared to when it was new. 100% = brand new. 80% = it holds 80% of original capacity.
💡 Note: On iPhone 15 and newer, Apple changed the Battery Health display. It now shows a cycle count and a health recommendation rather than a simple percentage. If you have an iPhone 15+, the key indicator is whether Apple says "Battery health is normal" or flags a service recommendation.
| Battery Health | Resale Impact | Notes |
|---|---|---|
| 100% – 90% | No deduction | Full price — buyer has no concern |
| 89% – 85% | –$10 to –$20 | Minor — most buyers still comfortable |
| 84% – 80% | –$20 to –$40 | Noticeable; "Fair" condition threshold |
| 79% – 75% | –$40 to –$70 | Battery replacement often expected |
| Below 75% | –$70 to –$120+ | Significant deduction; may need battery before sale |
