Not really no, it also likely isn’t a surprise to the engineers and project managers working on these products. Which is likely exactly why they have standout battery life: the project managers knew AI wouldn’t sell so they made the laptops appealing via conventional means anyway.
The project manager wouldn’t have a say in battery life, as it’s really just because of the ARM chip.
And I don’t think anyone thinks Copilot is good in its current form, AI hype or not. It feels like a web app with no real control over the machine.
It’s a common misconception but ARM isn’t inherently better at battery life than x86 though. It’s more that Qualcomm’s designs are as compared to the companies on the market that produce x86 hardware.
TIL, I did some research because of your comment and indeed, the difference in their use cases is mostly a market thing, not so much a limitation of each one. This answer is particularly good at explaining that.
