A longtime nightmare scenario for independent iPhone repair companies has come true: Apple has tied batteries to specific iPhones, meaning that only it has the ability to perform an authorized battery replacement on the newest versions of iPhones, two independent experiments have found. From a report: Battery replacements are among the most common repairs done by Apple and by independent repair companies. This is because lithium ion batteries eventually lose their ability to hold a charge, which will eventually make the phone unusable. Replacing the battery greatly extends the life of the phone: Apple CEO Tim Cook acknowledged earlier this year that battery replacements are resulting in fewer people buying new iPhones, which has affected Apple’s bottom line. It’s concerning on many levels, then, that on the iPhone XS, XS Plus, and XR, that any battery swap not performed by Apple will result in the phone’s settings saying that the new battery needs “Service.” An iPhone will still turn on and function with an aftermarket battery, but several important features are unavailable, and the iPhone warns users that they should seek service, presumably from an Apple Store.
