"If X + Y requires N energy, then 2X + Y requires LESS than 2N. So if you have a device with twice the space (because the screen is twice as big), you get more battery life.

This is obvious stuff... ...for people of at least average intelligence."

The only one who this is "obvious" to is Anal Baker.

What is defined as X and what is Y? The screen's dimensions?

X represents the screen's area and power draw.

Y represents the power draw of the rest of the system.

Since you don't have empirical facts, you really don't know.

If X is doubled, Y must increase.

No. X is the power required for the screen which is going to be proportional to the screens area at most. Y is the power necessary for the CPU, WiFi, and the other parts of a phone or tablet that don't need to change with increasing screen size.

Wrong.

What you like to ignore: That is why iPhones don't power 60" screens.

No. That is a strawman.

No, it fits into your hot air claim.

No, it doesn't.

So, since you're an "electronics expert" today, my question is; Why aren't iPhones used to power 60" screens?

It's a strawman.

Time to get on your bicycle.

What to catch you running away from the fact that there are energy costs proportional to the screen size and there are costs that are fixed, so if you double the screen size, you double the available volume for batteries but don't double all the energy costs.

It really is that simple.

It's why tablets such as the iPad have better battery life than iPhones of the same basic architecture.
