Never thought of that. But, I'm very sure Apple will use those big.LITTLE chips and use a dramatically smaller battery to give you 10 hours of battery life and thinner laptop. /S.

I feel like in the past few years, processors are remaining as fast but better power efficient, but the end-user never sees longer use out of them. Because manufacturers skimp on battery catching up with power efficiency :-(

If I built a computer as heavy as my first Thinkpad using a modern processor and filling the rest of the machine with batteries, I'd have a month of continuous use ;-)

There are regulations on how much li ion battey a machine may have to be allowed in the cabin pn a plane. I think many companies won't cross that limit. So something like the removable / modular batteries from the past might be great

Up to 100 Wh / battery, up to 160 Wh with airline approval. All laptops I know of have a 100 Wh battery at most. Macbook pro's used to have that size, but the latest gen has a smaller capacity. You can carry spare batteries, as long as they are for "personal use".

Word on the street was that the new MacBook Pros came with shrunken batteries because they couldn't get the terraced design to fit within design spec (thermals, I think) like they did with the MacBook. Hopefully in their next design iteration, they'll be able to fit a 99.5Wh battery back in the laptop.

Well... 100Wh at Core i7 + discrete GPU consumption is one thing, but if only an Atom-like core is half-asleep while I edit a field and the big cores only kick in while rendering a page, I would expect generously more than 10 hours.

I'm wondering why it's not possible to run some cores multithreaded and some just singlethreaded? I would like to see something like that.
