Apple has come under fire recently for a new policy regarding battery/ Screen replacements. If a battery/screen is not replaced by an authorized Apple Service Center or Authoried Apple Independent Repair Provider, there is a message on the device saying “Important Battery/ Screen Alert.” This message will appear even if the battery is a genuine OEM (Original Equipment Manufacturer) battery of the same quality as the one Apple uses. The change has been met with criticism from many, who argue that it is an unnecessary inconvenience. Others have pointed out that Apple is simply trying to protect its interests by ensuring that only trained professionals handle its products. Whether or not you agree with the policy, it’s important to be aware of it so that you can make an informed decision about how to best care for your iPhone.
if you take 2 brand new iPhone 11 and swap the screen , both devices will show this message. The notice is not an indication of how good or bad a screen it was; rather just noting that one replacement has different serial numbers than what’s stored in settings for each phone.” When We as an IRP puts in a new screen, we have to use a special software to calibrate the new serial number so that your iPhone starts recognizing this replacement screen and this software is not available to the public.
