Apple has apologised to iPhone owners following its admission that it slows down some older handsets to protect the ageing battery.
Last week, the technology giant confirmed it introduced a feature to its iOS operating system last year which manages performance on the iPhone 6, 6s and SE to help preserve battery life, which it says diminishes over time. Many customers and social media users have long speculated that the firm limits older devices to encourage users to upgrade, but the company said the feature was used to prolong the life of its products.
The company said on its website: "We have never - and would never - do anything to intentionally shorten the life of any Apple product, or degrade the user experience to drive customer upgrades."
The apology was accompanied by the announcement that the company will reduce the cost of replacement batteries for out-of-warranty iPhone 6s and later editions from $79 (£58) to $29 (£21) - starting in late January and available worldwide until December 2018.
Apple explained how lithium-ion batteries used in the iPhone age over time.
"All rechargeable batteries are consumable components that become less effective as they chemically age and their ability to hold a charge diminishes.
Apple also said it will issue an update to its operating system early next year to give users a better understanding of the health of their battery, so they can see if its condition is affecting performance.
