1.iPhone 11 Display Alert 

On September 24, Apple published a support document regarding replacement screens for iPhone 11, 11 Pro, and 11 Pro Max. This document addresses the reports we’ve seen over the past two days regarding the iOS 13.1 “Genuine iPhone Display” notification on iPhone 11 models. 

According to our in-house testing, if the display is replaced with a new assembly, (Genuine, OEM, or lower grade), a notification will appear on the lock screen for 4 days after the issue is first detected. The alert will then live in the settings menu for another 15 days. After 15 days, it will then be moved to Settings > General > About. Here is a breakdown of when and where this alert will be shown on your phone. 

PLEASE NOTE THAT THIS DISPLAY MESSAGE DOES NOT AFFECT YOUR 
ABILITY TO USE YOUR DEVICE.

 
 
2. Apple discouraging third-party iPhone battery swaps with new “Service” message on iPhone XS, XR, XS Max 

According to latest market news, Apple is taking new measures within iOS to prevent aftermarket battery swaps for the iPhone. As detailed by iFixit, Apple has activated a“dormant software lock" in iOS that blocks features like Battery Health in Settings when an iPhone uses a battery that was not installed by Apple itself.

Essentially, if your iPhone needs a new battery and you take it upon yourself to replace the battery, the Settings app will display a “Service” message that reads "Important Battery Message: Unable to verify this iPhone has a genuine Apple battery. Health information not available for this battery." 

Notably, this message will appear whether you install an aftermarket battery or an official battery from Apple. The only scenario in which it doesn't appear is when Apple itself or an Apple authorised service provider does the battery swap.

We did test and verify that this new software lock is in both iOS 12 and the iOS 13 and affects the iPhone XR, iPhone XS, and iPhone XS Max., but other models are not affected. Now the main question is that when you replace the battery is whether the battery will work or not? Yes, most definitely it will work. Users can plug it in and the phone will function properly they just won't be able to use the super Apple feature of known as the Battery Health.

According to the latest market information, replacing to the original battery protective board and original flex cable can solve this problem. And some factories are working on inventing a repair tool to solve this problem.
