Apple has apologised after facing criticism for admitting it deliberately slows down some ageing iPhone models.
The company now says it will replace batteries for less and will issue software in 2018 so customers can monitor their phone's battery health.
Some customers had long suspected the company slowed older iPhones to encourage customers to upgrade. Apple admitted slowing some phones with ageing batteries but said it was to "prolong the life" of the devices.
In a statement posted on its website, the firm said it would reduce the price of an out-of-warranty battery replacement from $79 to $29 in the US for anyone with an iPhone 6 or later. In the UK the prices will drop from £79 to £25.
