Apple has posted the biggest quarterly profit of all time despite a fall in iPhone sales.
The world's biggest company posted profits of US$20.1 billion ($27.2b) in the crucial final three months of the year, breaking its own record set two years ago, according to the Daily Telegraph.
It came after the release of the iPhone X in November, the biggest update of the handset to date, as well as the release of the iPhone 8 in September.
Although Apple sold 77 million iPhones in the three month period, a 1 per cent fall from last year, the higher price of the new handsets meant revenues from selling iPhones increased.
"iPhone X surpassed our expectations and has been our top selling iPhone every week since it shipped in November," Cook said.
