Apple has told its network that they should proceed with repairs if the defect does not include battery. These cover defects in display screens, logic board, microphones, and other parts

MacRumours report read, “iPhones with aftermarket batteries installed by third-party repair shops are now eligible for service at Genius Bars and Apple Authorized Service Providers, according to an internal Apple document obtained by MacRumors from three reliable sources.”
It is to be noted here that Genius Bar and Apple authorised service centers were previously not allowed to repair iPhone models fitted with third-party batteries.
Repairs not related to battery
Apple has told its network that they should proceed with repairs if the defect does not include battery. These cover defects in display screens, logic board, microphones, and other parts.
The report read, “If the repair is related to the battery itself, the Genius Bar and AASPs are now permitted to replace the third-party battery with an official Apple battery for the standard fee. Before starting the repair, the Genius Bar must drain the third-party battery to less than 60 percent of a charge.”
It continued, “If the iPhone’s battery tabs are broken or missing, or there is excessive adhesive, the Genius Bar and AASPs are permitted to replace the entire iPhone for only the cost of a battery replacement at their discretion.”
It is to be noted here that Apple is facing string headwinds in many of its international markets. The company has been going through declining number of iPhone sales since last few quarters.
