Apple discourages iPhone self-repair with a dirty trick

Once again, Apple has demonstrated its disdain for people who want to do simple repairs on their equipment. This time, Apple has changed the iPhone's firmware so people who replace an old battery with a new Apple-branded battery will see a "Service" message on their phone that won't go away. The Service message says "Unable to verify this iPhone has a genuine Apple battery. Health information not available for this battery." The phone also will also refuse to show any diagnostic information about the health of the battery. The only way to avoid the message and be able to see the health of the battery is to have the battery replaced by an Apple Authorized Service Provider who has access to Apple's proprietary internal diagnostic software.

From iFixit:

Technically, it is possible to remove the microcontroller chip from the original battery and carefully solder it into the new battery youre swapping in, restoring the Battery Health featurebut the procedure isnt for the faint of heart, and its an unreasonable requirement for any repair, much less something as simple as a battery swap.

Swapping in another genuine Apple battery into an iPhone XSFortunately, your replacement battery will continue to work perfectly fine, and youll get all of the benefits that come with a new batteryweve confirmed that this doesnt throttle the iPhones performance on a healthy battery, for example. But you wont be able to easily see your batterys health and know when its time to replace it.

Then again, this is a huge problem for iPhone owners who may not know about this new, sneaky lockdown, and it will undoubtedly cause confusion: theyll replace their own battery and notice the Service message, then begin troubleshooting a problem that isnt there.
