The Portuguese consumer association Deco Proteste is suing Apple for a software update that deliberately slows iPhones to spare the battery.
That would have happened in 2017 with the iPhones 6, 6 Plus, 6S and 6S Plus.
The company previously went through the dust as iPhone owners were not notified of the update and may have bought a replacement phone or battery due to the (old) device slowing down.
According to Apple, the software update was necessary to prevent the phones from suddenly failing because the outdated battery could not handle a peak moment.
The company deliberately denies having done anything to shorten the lifespan of iPhones and thus force consumers to buy a new device.
At the end of last year, the Spanish and Belgian consumer associations also filed lawsuits.
Previously, a similar case in the United States was settled for $ 500 million (approximately € 412 million), without Apple acknowledging debt.
