3. Estimated battery-repair milestone

   Estimate 10 Feb 2030

   The EU label rates the battery for 1,600 full charges before it falls to 80%. At one full charge a day, that is about 4.4 years after launch. Real phones vary. This is not a promised failure date.EPREL

   A first screen repair has no sourced age. An official screen price, where we have one, is a cost only.

   No observed resale-price history is available to establish a drop in value. We do not forecast a resale-drop date from a support reference.

How this chart is built

• Launch uses the release date stored for the phone, with its source. On an iPhone the Apple support page is listed first.
• Software support uses the same reference as the rest of FixIndex: a manufacturer date when it is the later one, otherwise a conservative floor calculated from EU-label data. The calculated floor is not a confirmed end date.
• The repair marker is an estimate: EU rated charge cycles, one full charge a day, counted from the release date. Official battery and screen prices are costs, not dates.
• No resale-drop date is forecast. A manufacturer date or calculated EU floor does not establish a market-value change. Observed sell quotes can support a euro comparison, but without an observed price history they do not establish when a drop occurs.

Still open: observed trade-in prices, and a sourced age for screen repairs.
