A surge in iPhone sales, especially in China, has led to a doubling of profits at Apple since the start of the pandemic.

The results reflected “optimism” about the days ahead, Apple’s boss said.

Rival tech firm Facebook also reported bumper revenues and profits.

But the social media giant warned Apple’s latest software release could undermine its prospects later in the year.

Apple has seen sales of its phones, apps and other devices rise throughout the pandemic, as consumers spent more time working, shopping and seeking entertainment online.

Customers continued to upgrade to Apple’s new 5G phones which were rolled out last year, and also bought Mac computers and iPads to tackle working and studying from home, the firm said.
