iPhones with third-party batteries are now eligible to be repaired at Genius Bars and Apple Authorized Service Providers according to internal Apple documents.
Before, Apple policies stated that customers were ineligible to receive any kind of repair service if their iPhones were previously repaired with any non-original, third-party components, meaning you’d be taking a big risk by replacing an iPhone battery yourself.
According to the reports, technicians will now be able to carry out services as normal for repairs unrelated to the battery, like microphones, logic boards, or the display, even if they spot a third-party battery when they open up your phone.
