The issue persists even if you use a genuine, authorized Apple battery, iFixit says. These chips can be found on most batteries but Apple has pushed it up a notch and added an authentication feature to it, which locks the battery replacements.
iFixit said, "Apple is locking batteries to their iPhones at the factory, so whenever you replace the battery yourself-even if you're using a genuine Apple battery from another iPhone-it will still give you the "Service" message".
There's a microcontroller from Texas Instruments onboard iPhone batteries that communicates health information to the phone. The deeper access should make researchers' lives a lot easier, able to access deeper iOS functions without waiting for a jailbreak to be available for every update.
That also means those who want to swap out their phone's battery themselves won't be able to take advantage of the iPhone feature that tells you how your phone's battery is performing, according to the report. For now, this Service message affects only the iPhone XR, XS and XS Max. Assuming the replacement battery is in good condition, it'll work fine regardless of the service warning.
iFixit notes that most users won't realise that nothing is wrong, "this is a huge problem for iPhone owners who may not know about this new, sneaky lockdown, and it will undoubtedly cause confusion: they'll replace their own battery and notice the 'Service'message, then begin troubleshooting a problem that isn't there".
In response to growing lobbying for right to fix bills, Apple has insisted that it is motivated by controlling the quality of repairs and safety concerns (particularly relevant in situations like swollen batteries) rather than money.
To check if Apple is throttling your phone, go to Settings Battery Battery Health. In 2017, for example, it was discovered that the company intentionally throttles old iPhone batteries to preserve their performance.
Unlike its bug bounty program, the iOS Security Research Device Program, as it is named, will be invite-only; however, applications are open to everyone. A move to label these repairs as "not genuine" in iOS could be a stepping stone to locking people out of their devices in the future, just like it happened when people first tried to fix Touch ID on their iPhones. Apple clients reportedly confirmed interest in paying as a lot as $600 extra for a foldable iPhone, per the research. Furthermore, it could serve to build consumer distrust for such repairs, which would also help Apple's cause in fighting fix regulation.
Apple has always been trying to push users to shun third-party repairers and go through Apple for device repairs.
