So it should come as no surprise that millions of these older models are gradually being phased out. In fact, Apple cut support for the iPhone 6 two years ago with the release of iOS 13. No, the iPhone 6 is not being phased out. It will continue to work as long as you want. You simply won't be able to update it to the latest versions of iOS, and you won't be able to take advantage of the new features offered by those newer versions.
The iPhone 6 sold very well, making it the best-selling iPhone model and the most successful smartphone to date. Apps can take advantage of the increased screen size of the iPhone 6 and 6 Plus to display more information on the screen; for example, the Mail application uses a dual-panel design similar to that of its iPad version when the device is in landscape mode on the iPhone 6 Plus. Soon after their public release, it was reported that the chassis of the iPhone 6 and iPhone 6 Plus was susceptible to bending under pressure, for example, when carried tight in the user's pocket. You might also like to know how long Apple is compatible with Macs and how long Apple supports iPads.
However, some aspects of the iPhone 6's design were also criticized, such as the plastic strips on the back of the device to place the antenna, which damaged the otherwise metallic exterior, and the screen resolution of the standard-sized iPhone 6, which was lower than that of other devices in its class. Some iPhone 6 and iPhone 6 Plus models have a problem where the front camera is offset in some way or out of place. Statista (a provider of market and consumer data) publishes a graph showing how long Apple has been supporting older iPhones. This suggests that while the iPhone 6s may receive software support for a while, it may not be possible to repair it if it breaks.
Apple will support iPhones (and all the devices it makes) for seven years starting from the last time it sold that particular model. Some users reported that the 64 and 128 GB iPhone 6 models had experienced performance issues, and that some 128 GB iPhone 6 Plus models, on rare occasions, crashed and restarted randomly.
