Apple Is Locking iPhone Batteries to Discourage Repair
By activating a dormant software lock on their newest iPhones, Apple is effectively announcing a drastic new policy: only Apple batteries can go in iPhones, and only they can install them.
If you replace the battery in the newest iPhones, a message indicating you need to service your battery appears in Settings > Battery, next to Battery Health. The “Service” message is normally an indication that the battery is degraded and needs to be replaced. The message still shows up when you put in a brand new battery, however. Here’s the bigger problem: our lab tests confirmed that even when you swap in a genuine Apple battery, the phone will still display the “Service” message.
It’s not a bug; it’s a feature Apple wants. Unless an Apple Genius or an Apple Authorized Service Provider authenticates a battery to the phone, that phone will never show its battery health and always report a vague, ominous problem.
We first saw this phenomenon in a damning video from Justin at The Art of Repair, and we were able to replicate it on an iPhone XS running both iOS 12 and the iOS 13 beta. Swapping in a new genuine Apple battery from another iPhone XS resulted in the “Service” message popping up in the Battery Health section, followed by an “Important Battery Message” telling us that it’s “unable to verify this iPhone has a genuine Apple battery.” Justin says this only affects the iPhone XR, XS, and XS Max for the time being.
Put simply, 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. The only way around this is—you guessed it—paying Apple money to replace your iPhone battery for you. Presumably, their internal diagnostic software can flip the magic bit that resets this “Service” indicator. But Apple refuses to make this software available to anyone but themselves and Apple Authorized Service Providers.
Our friend Justin notes that there’s a Texas Instruments microcontroller on the battery itself that provides information to the iPhone, such as battery capacity, temperature, and how much time until it fully discharges. Apple uses its own proprietary version, but pretty much all smartphone batteries have some version of this chip. The chip used in newer iPhone batteries includes an authentication feature that stores the info for pairing the battery to the iPhone’s logic board. In simple terms, if the battery doesn’t have the unique authentication key the iPhone’s logic board is expecting, you’ll get that “Service” message.
