Lol, you literally quoted me, didn't actually read what you quoted, and then did something completely different.

Do you know that battery life ≠ battery capacity? That is not the same measurement as I have already tried to teach you 3 times.

Please state the calculation that you would use to "determine how often you have to recharge" that is valid for Wh and not for Ah.

What is its idle power draw? What is its power draw under load? Playing video? Sleep mode? That source gives nothing which determines battery life. All it gives is a nearly useless capacity number, just like all other manufacturers. So not valid at all. You still have exactly 0 more information about battery life.

If I am wrong, please state your calculations of what the battery life is with that 54Wh battery.

Your entire argument was "Ah is useless and Wh gives consumers the information to determine battery life" So go ahead, determine the battery life.

How is this any different at all if they said that it is a 5.8Ah battery? They don't give any current or power draw.

As an exercise:

can you tell me the battery life difference between an arbitrary Laptop A with a 54Wh battery and Laptop B with a 27Wh battery?

Not quit sure where battery life is comming from, thats not my argument. To restate and also better phrase my argument: Stored energy is the better measure for consumers for the quantification of the battery size in a consumer device compared to ~~Ah~~ stored charge.

Now i can cross compare devices based on that and do not have to worry about the Voltage of the battery of any other devices.

Please state the calculation that you would use to "determine how often you have to recharge" that is valid for Wh and not for Ah.

I never claimed that this is possible. I wrote "can recharge" not 'have to". I am referring to devices like a power bank which i can calculate with a simple:

powerbank has 100Wh and phone has 25Wh so 100/25=4 -> i can recharge my phone 4 times using that powerbank.
