Apple is discouraging third-party iPhone battery swaps with the 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. 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 or an Authorised Service provider. 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.
All of this stems from a Texas Instruments micro controller on the battery itself, which includes an authentication feature that includes details for pairing the battery to the iPhone's logic board. If the authentication key provided by the battery doesn't match what your iPhone is expecting, you'll get the“Service" warning. Apple and its partners are the only ones who can clear this “Service" message.
We did test and verify that this new software lock is in both iOS 12 and the iOS 13 beta 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 work or not?
The answer is Yes, most definitely it will work. Users can plug it in and the phone will function properly just they won't be able to use the super Apple feature of known as the Battery Health.
