Apple has published a letter to its customers today on its website apologizing for slowing down users’ iPhones after upgrades to recent versions of the iOS operating system. The company said they’ve begun hearing feedback about how they manage the performance of iPhones running on older batteries. “We know that some of you feel Apple has let you down. We apologize.”

In the letter, Apple notes how lithium-ion batteries tend to chemically age over time, therefore becoming less reliable. This would result in devices like the iPhone 6, 6s, and SE randomly shutting down during “peak workloads.” A patch was delivered in iOS 10.2.1 that fixed this issue, but customers were left with slower performance than what was available with iOS 10.2. Still, no one really noticed, and Apple introduced the same patch for iPhone 7 with iOS 11.2.

But of course, things got blown out of proportions when developers began analyzing Apple’s behaviors with benchmarks. It was discovered devices with their original batteries were much slower than ones that had their cells swapped out for new ones. In short, various outlets such as websites, newspapers, and even local news stations got word of the news and broke it to basically everyone not living under rocks. Not long afterward, lawsuits were flying all over the place and angry customers got frustrated with the Cupertino company for slowing down their iPhones without them knowing.

What many were told to think, however, was that this move from Apple was a push to get customers to upgrade their existing iPhone to the newest model. While it’s the easiest way to view the situation, the company wants to convince people it’s to protect older batteries. And honestly, it’s probably best to drop the whole “Apple’s doing it on purpose! They want to spend a thousand dollars on a new one!” act and just believe the company on this one.

To repair its relationship with consumers, Apple says it’ll begin offering battery replacements for customers with an iPhone 6 or newer for $29, $50 lower than what they currently charge, throughout 2018 starting next month. This will bring back the same out-of-box performance you experienced the day you bought your device. In early 2018, the company will also introduce new features in iOS that will let you monitor your battery to determine whether it’s capable of delivering max performance anymore.

We’ll let you know of any more information surrounding this story that surfaces.
