US states are investigating whether Apple broke the law to slow down iPhones

US states are investigating whether Apple has broken the law in the past by deliberately slowing iPhones. The states, led by Arizona, are investigating whether that practice has misled consumers.

At least attorneys general from Texas and Arizona are on board, but a majority of US states are involved in the investigation, according to Reuters. The states want to know if Apple has violated laws that prevent consumers from being deceived. To this end, the states have requested information from Apple.

The research is about slowing down iPhones to prevent them from failing during peak loads. Apple had quietly implemented this, so that users of older iPhones in particular saw the speed of their phone decrease. Slowing down is now an option in the settings. The US federal government has also raised questions about the issue. Apple has settled a lawsuit over slowing down iPhones with a settlement.

Apple and the attorney general have not confirmed the information from Reuters. The news agency says it has seen documents of the case.
