Buying older smartphones is becoming increasingly popular as users realize they don't necessarily need the latest and greatest. One of the phenomena we've noticed over the past five years is buying refurbished older iPhones. But if you're a die-hard WhatsApp user, avoid buying the iPhone 5s, iPhone 6 and iPhone 6 Plus as they are no longer supported.
Last year, WhatsApp announced that support for iOS 15.1 and below would be discontinued starting May 2025 as the devices are over 10 years old. But it has been extended to the end of May. Since the past four days, WhatsApp has no longer been available on the three iPhone models above. So if you receive an attractive offer to buy these three iPhones at a bargain price, we advise you to avoid it.
It has become common for application developers to not support older versions of devices due to access to a number of APIs, in addition to using the modern infrastructure offered by more recent operating system versions.
