iPhone SE (1st Gen) Battery

Each replacement battery is designed for specific iPhone models. Check the “Compatibility” info box on this product page for details or use our compatibility checking tool to find out whether your model is compatible. If you’re unsure which model you have, you can verify under Settings → General → About or use the model identification information provided in the compatibility checking tool.

If your iPhone drains unusually fast, runs hot, or shows Battery Health below 80%, it’s time for a battery swap. Apple designed the iPhone 14 and earlier models to retain at least 80% capacity for around 500 full charge cycles, while the iPhone 15 and newer aim for 1,000 cycles under ideal conditions. Actual battery life varies with usage, but if you see a performance drop earlier, a fresh battery is the simplest, most cost-effective way to keep your phone running smoothly.

Depending on your iPhone model and iOS version, you may see an “Important Battery Message” or a missing Battery Health indicator—this doesn’t affect your phone’s everyday performance. As this is a software feature, your options will depend on the version of iOS you are currently using.

• On iOS 17.6 and earlier, your iPhone may display a warning about the “genuineness” of the battery after the repair, even when using original Apple parts.
• From iOS 18 onwards, Apple’s Repair Assistant allows for parts authentication. While Apple has promised to improve support for third-party batteries in June 2024, including showing battery health metrics, as of iOS 18.2.1 support for third-party batteries remains unimplemented. If your iPhone functions normally, you can safely ignore the warning.
