After the very strong critics of the media and the iPhone users, Apple finally started replacing the batteries at a discounted price. Apple is offering the battery replacement for $29 after apologizing to customers for slowing down the iPhones.
But there are no guidelines about the eligibility for the discounted replacements of the batteries. According to the reports, Apple is running some diagnostic test to know the eligibility. Some users had also reported that, Apple denied them a battery swap since their devices passed the diagnostic test.
However, Apple had confirmed that they will be replacing the batteries on an iPhone 6 or later. Regardless of whether or not a diagnostic test shows that the battery retains less than 80 percent of its original capacity. Customers who had paid more for the battery replacement are eligible for the refund in price difference.
