A UK court has approved a class action lawsuit against Apple, potentially impacting millions of iCloud users. The claim alleges Apple secretly reduced iPhone performance to manage battery issues, leading to unwanted device replacements. The lawsuit seeks approximately £3 billion in compensation for affected users. This marks a significant step forward in a case first brought in 2017, and is one of the largest of its kind in the UK. If successful, eligible individuals could receive compensation for the cost of new batteries or devices. Apple has consistently denied the allegations, maintaining that the performance management was intended to prevent unexpected shutdowns. The trial will determine whether Apple intentionally misled consumers.
