The decision means that from January 1, 2018, WhatsApp will pull support for the app on iPhone 3GS and older models, as well as iPhones running iOS 6 and earlier. The list of unsupported phones also includes Android 2.1 and 2.2, BlackBerry OS, and Windows Phone 7.
Explaining its reason for the move, WhatsApp said that when it was founded back in 2009, the mobile landscape was very different.
"About 70 percent of smartphones sold at the time had operating systems offered by BlackBerry and Nokia," the company said. "Mobile operating systems offered by Google, Apple and Microsoft - which account for 99.5 percent of sales today - were on less than 25 percent of mobile devices sold at the time."
Apple's iPhone 3GS was released in June 2009, while iOS 6 was released on September 19, 2012, followed by iOS 7 in 2013. According to Apteligent Research, less than 0.04 percent of iPhone users are currently using iOS 6. Apple's most recent mobile OS, iOS 11, was released on September 19, 2017, and accounts for over 75 percent of active iOS users.
