Fake Batteries Are Becoming a Big Problem
One of the biggest reasons that Apple is cracking down on third-party batteries and all related, unauthorized battery repair is that fake batteries have become an epidemic for electronics users, and iPhones are no exception. More and more manufacturers are trying to make fake “replica” iPhone batteries and flood the market with them to make a quick buck. While some users buy these batteries online, a frequent target for these replicas are third-party repair services looking for a good deal on iPhone batteries.
In other words, Apple needs to guarantee the battery supply line from creation to installation on your iPhone to make sure that these ubiquitous replicas aren’t involved. If they are involved, Apple wants to make it clear that it doesn’t support them and will not enable those battery functions.
