Apple sued for slowing iPhone 4S with iOS 9 upgrade

SAN FRANCISCO — Apple is facing a lawsuit that alleges its iOS 9 mobile operating software significantly slows down the iPhone 4S.

The lawsuit filed in New York federal court and first spotted by Apple Insider is seeking $5 million from Apple.

"The update significantly slowed down their iPhones and interfered with the normal usage of the device, leaving Plaintiff with a difficult choice: use a slow and buggy device that disrupts everyday life or spend hundreds of dollars to buy a new phone," the lawsuit says. "Apple explicitly represented to the public that iOS 9 is compatible with and supports the iPhone 4S. And Apple failed to warn iPhone 4S owners that the update may or will interfere with the device's performance."

Apple could not be immediately reached for comment.

Here's the lawsuit filed this week that was uploaded by Apple Insider.
