Joules are already a unit that people use in daily life. They’re the SI unit. They’re used in science. The manufacturers should have chosen a unit that’s applicable across disciplines, so that the knowledge is transferable. That would have helped people learn science from their phones. Instead, we use a stupid unit that isn’t useful for any other application except commercial power systems, and doesn’t make people smarter when they learn it. When you learn Joules, you get smarter, because you’re learning to more easily navigate lots of energy applications.
I use Amps and hours in my everyday life much more often than Joules. The manufacturers used those units (which are both SI units) because they are the most useful in this case. If you know how many amps you are using you know how long your battery will last. If they gave the joules remaining they would need to give you a Joules/time reading to get the same information. To get that value they would have to measure how many Amps were being used so why bother converting it?
Maybe you should learn a bit more about Amperage instead of expecting everyone else to learn about Joules.

Some people, sure. You and some in your close circle of acquaintances likely use it.
Not once have I ever needed to measure something in joules. I suspect that many people, if not most, don’t use joules in daily life.
I would be okay with measuring battery capacity in calories in America.
