You might have to wait two weeks to replace the battery inside your Apple iPhone 6
Late last month, Apple apologized for quietly using software smuggled into certain iPhone models which throttled the CPU of these handsets. Apple explained that it was forced to do this so that these iPhone units wouldn't shutdown when met with a complex task that could tax the older and weaker batteries inside these phones. To make up for what it had done, Apple sliced 63% off the price of a battery replacement for the iPhone 6 and later, cutting the price to $29 from $79 for the remainder of the year.
Another CNBC reporter made an appointment at Best Buy to replace the batteries on her two iPhone 6 models, and was turned away because the store was out of stock. Even if you score an appointment at an Apple Store or Best Buy for a battery replacement, it doesn't mean that the actual location has any of the batteries you need in stock. We suggest that before you make an appointment, call the store in question to make sure that they have inventory of the cell made for your specific iPhone.
