The inquiry is in early stages, and it's too soon to conclude if any enforcement will follow, the report said.
The company later retracted this, stating: "We have never - and would never - do anything to intentionally shorten the life of any Apple product, or degrade the user experience to drive customer upgrades".
Last year, Apple disclosed that it intentionally slowed down the performance of older iPhone models to lengthen the life of their batteries.

"Apple doesn't need to rely on one model to perform very well to be able to achieve the financial results they are aiming at", Ms. Peng said. As per the announcement, some key features coming with iOS 11.3 include a battery health monitor, new Animoji, the ability to disable slowdowns, improvements to ARKit, and the introduction of Health Records.
