Apple Inc defrauded iPhone users by slowing devices without warning to compensate for poor battery performance, according to eight lawsuits filed in various federal courts in the week since the company opened up about the year-old software change.
The tweak may have led iPhone owners to misguided attempts to resolve issues over the last year, the lawsuits contend, according to a Reuters report.
All the lawsuits - filed in US District Courts in California, New York, and Illinois - seek class-action to represent potentially millions of iPhone owners nationwide.
A similar case was lodged in an Israeli court on Monday, the newspaper Haaretz reported.
Apple did not respond to an email seeking comment on the filings.
The company acknowledged last week for the first time in detail that operating system updates released since “last year” for the iPhone 6, iPhone 6s, iPhone SE and iPhone 7 included a feature “to smooth out” power supply from batteries that are cold, old, or low on charge.
Phones without the adjustment would shut down abruptly because of a precaution designed to prevent components from getting fried, Apple said.
The disclosure followed a Dec. 18 analysis by Primate Labs, which develops an iPhone performance measuring app, that identified blips in processing speed and concluded that a software change had to be behind them.
One of the lawsuits, filed Thursday in San Francisco, said that “the batteries’ inability to handle the demand created by processor speeds” without the software patch was a defect.
“Rather than curing the battery defect by providing a free battery replacement for all affected iPhones, Apple sought to mask the battery defect,” according to the complaint.
