It isn't secret. And not "activated". It came with a softwaere update
and immediatly active.
It basically pairs a battery secial number to the phone. Sop that is why
even if you replace battery with genuine Apple battery, it will complain.
This complaint happens onnce, and the only permanent side effect has
been the long standing policy of disabling the "battery health"
capabilities which have been in effect with 3rd party batteries since
late 2017.
The marketing reasoning: the battery health software looks at the
history of a battery to deterkine how much it has degraded. Change the
battery and all of a sudden, tthe old battery's history can't be used to
determine the new battery's health so the phone refuses to give you the
info.
Obviously, Apple repair shops have thye magic software tool that tells
the phone to accept the new battery, and that could have been made
automatic to allow anyone to replace the battery. However, in fairness
to Apple, authoried repair shops are able to get that tool and do
battery changes ( but I think TouchID changes are still Apple-only as it
touches the secure enclave).
