Your iPhone has been refurbished according to the strictest quality standards.
However, some manufacturers impose restrictions on repairs in order to control the refurbishment market.
If you see a message regarding your battery, screen, or camera as shown in the examples below: Rest assured: this is neither a defect nor a problem!
It simply means that an original component has been replaced with an equivalent of the same quality.
These messages in no way affect your device’s performance and will disappear after 4 days.
Replacing the battery may trigger error messages, even when using an original part. A notification will appear on the lock screen for 4 days and in the settings for 15 days.
After this period, the notification remains visible in Settings > General > About.

💡 These messages have no impact on your device’s performance.
📌 The only drawback is that it becomes more difficult to monitor your battery’s health status and therefore anticipate its replacement.
Screen replacement may also trigger error messages.
A notification will appear on the lock screen for 4 days and in the settings for 15 days.
As with the battery, the notification remains visible in Settings > General > About.

💡 If the message “Unknown Part” appears, it simply means that the component has probably been replaced. In any case, the component will work just as well as an original one. And if necessary, your device remains under warranty in the event of a defect.
