If your iPhone 6 or other covered model is running slowly, time is running out to do something about it —at least the time is running out to pay less than full price for the service. Apple has been running a reduced cost battery replacement program in response to customer complaints but this ends on December 31, 2018. Thereafter, replacing any iPhone battery will cost you $79 for models older than the iPhone XS, iPhone XS Max, and iPhone XR instead of the current $29.
The reduced price covers the iPhone 6 and also newer models up to and including the iPhone X and iPhone 8 family. All you have to do is either take your phone to a Genius Bar appointment in an Apple Store or send it in to Apple for repair.
We’ll be taking my wife’s iPhone 6 Plus in before the end of the year. But the “All you have to do…” isn’t very easy for those of us who don’t live near an Apple Store.
