Apple sold a record-breaking 47.8 million iPhone handsets in quarter four of 2012, up from 37 million in the same period a year earlier.
The American manufacturer also recorded all-time-high revenue of $54.5 billion (£34.4 billion) in the 13 weeks to December 29th, alongside peak profits of $13.1 billion.
Chief executive Tim Cook said: "We are very confident in our product pipeline as we continue to focus on innovation and making the best products in the world."
The company released its latest handset, the iPhone 5, on September 21st, and fans queued for hours outside retail stores to be among the first to get their hands on the gadget.
The screen size increased from 3.5 to four inches while retaining its Retina display quality, and Long Term Evolution (LTE) technology was incorporated to allow 4G network connections.
Operated by the most modern iOS 6 platform, the device provides owners access to the extensive App Store catalogue and exclusive tools like Passbook.
