Do not see the battery health number

Kindly reach out to the Store/Individual/Agency from whom you acquired your iPhone. They would be best equipped to confirm whether the device has undergone servicing by an unauthorized service provider.

In case you recall not encountering this message at the time of purchase and it surfaced after an update, it's important to note that this message is visible specifically on iOS 15.2 and subsequent versions. It might be beneficial to inquire about any recent updates or changes made to the device's software configuration that could have triggered this notification.

Understanding the circumstances surrounding the appearance of this message could provide insights into any alterations in the device's service history or software updates that have brought about this notice.

Camera and service history

With iPhone 12 models and later using iOS 15.2 and later you can go to Settings > General > About to see the parts and service history of your iPhone and you can see if the camera has been replaced. If the repair was done using genuine Apple parts and processes, you will see "Genuine Apple Part" next to the Camera.

• You will see an Unknown Part  message if the camera installation is incomplete or if the camera:
• Was replaced with a nongenuine camera
• Was already used or installed in another iPhone
• Isn't functioning as expected

This message doesn't affect your ability to use your iPhone or access your camera.

Battery and Display and service history

With iPhone 11 models and later, excluding iPhone SE (2nd and 3rd generation), using iOS 15.2 and later, you can go to Settings > General > About for the parts and service history of your iPhone. You can also find out if the display has been replaced. If the repair was done using genuine Apple parts and processes, "Genuine Apple Part" will appear next to Display.

• An Unknown Part  message will appear if the display installation is incomplete or if the display:
• Was replaced with a nongenuine display
• Was already used or installed in another iPhone
• Isn't functioning as expected

An additional message might appear that says "Apple has updated the device information for this iPhone." This means that Apple has updated the device information maintained for this iPhone for service needs, safety analysis, and to improve future products. 

If your iPhone's parts have been previously replaced, repaired, or serviced by an unauthorized service provider, it's worth noting that Apple may decline to provide service for your device. The decision to refuse service will depend on the specific components that were affected by the unauthorized service.

No see the battery health numbeR

Do you mean that, when you go to Settings>Battery>Battery Health, there is no number next to "Maximum Capacity"? If so, that either means that you had the battery replaced by someone who wasn't Apple or an Authorize Apple Service Provider or that there is something wrong with your battery. There's not much you can do about the first. For the second, contact Apple to have your phone evaluated:

Don't worry, I can help you with that! There are a couple of reasons why you might not be seeing the battery health number:

1. Your iPhone model: Battery health percentage is currently only available on iPhone 6 and later models. If you have an older iPhone, the "Battery Health & Charging" section might not appear at all.

2. Software update: Make sure your iPhone is running the latest version of iOS. Older versions might lack the feature or have bugs that can hide the battery health number.

3. Settings issue: Sometimes, a simple toggle setting can be the culprit. Here's what to check:

• Go to Settings > Battery.
• Tap on Battery Health & Charging.
• If you see a toggle called "Optimize Battery Charging," ensure it's turned off. This feature can temporarily hide the battery health number to optimize charging cycles.

4. Hardware issue: In rare cases, hardware issues can also prevent the battery health information from displaying correctly. If you've tried the above solutions and still can't see the number, it's best to contact Apple Support for further diagnostics.
