I think amp-hours are confusing and I wish they just gave us battery life figures in joules

Welcome to the Unpopular Opinion community!
How voting works:
Vote the opposite of the norm.
If you agree that the opinion is unpopular give it an arrow up. If it's something that's widely accepted, give it an arrow down.
Guidelines:
Tag your post, if possible (not required)
- If your post is a "General" unpopular opinion, start the subject with [GENERAL].
- If it is a Lemmy-specific unpopular opinion, start it with [LEMMY].
Rules:
1. NO POLITICS
Politics is everywhere. Let's make this about [general] and [lemmy] - specific topics, and keep politics out of it.
2. Be civil.
Disagreements happen, but that doesn’t provide the right to personally attack others. No racism/sexism/bigotry. Please also refrain from gatekeeping others' opinions.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Shitposts and memes are allowed but...
Only until they prove to be a problem. They can and will be removed at moderator discretion.
5. No trolling.
This shouldn't need an explanation. If your post or comment is made just to get a rise with no real value, it will be removed. You do this too often, you will get a vacation to touch grass, away from this community for 1 or more days. Repeat offenses will result in a perma-ban.
6. Defend your opinion
This is a bit of a mix of rules 4 and 5 to help foster higher quality posts. You are expected to defend your unpopular opinion in the post body. We don't expect a whole manifesto (please, no manifestos), but you should at least provide some details as to why you hold the position you do.
Instance-wide rules always apply. https://legal.lemmy.world/tos/

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.
