Ok so ios14 is coming soon, how long can we keep using iphone6 running on ios12?

Your phone will continue to perform just fine for normal tasks like calling, texting and browsing the internet. However, app manufacturers may soon end support for iOS 12 over the next year or two, meaning that some apps may cease to function as they require iOS 13 or later, which is not supported by your device.

I hope this helps a little more than the arseholes that have responded already.
