25 million iPhone users could be eligible for payouts as courts oversee a claim that Apple secretly slowed down the batteries of older phones.
The company is accused of misleading users over an upgrade that it said would enhance performance but, instead slowed phones down.
The models covered by the claim are the iPhone 6, 6 Plus, 6S, 6S Plus, SE, 7, 7 Plus, 8, 8 Plus and iPhone X models.
The claim alleges Apple slowed down the performance of older iPhones, in a process known as “throttling”, in order to avoid expensive recalls or repairs.
It relates to the introduction of a power management tool released in a software update to iPhone users in January 2017, to combat performance issues and stop older devices from abruptly shutting down.
Attorney Justin Gutman is seeking damages of around £768m for up to 25 million UK iPhone users.
Apple however says it has “never” intentionally shortened the life of its products.
