Earlier this year when Apple was caught slowing down their phones via software updates, a move that cost the company a pretty penny. Samsung also took jabs at Apple saying that they don’t engage in planned obsolescence. After Apple’s practices came to light, Italy’s consumer watchdog announced that it was investigating Apple and Samsung. Today, the committee determined was Samsung was guilty of the same practices as Apple.

Apple said that older iPhones were slowed down through updates to prevent accidental shutdowns. Li-ion batteries degrade over time, and they can’t handle the surge in power requirement when the chip takes on heavy load. Which is why Apple limited the processor speed on other devices through updates. Not only did Apple apologise, but it also released an update which allowed users to opt out of this functionality.
