I have an XPS 17 with 12th gen and it drains around 50% battery per hour on a zoom call. edit: My laptop has a i7-12700H, which uses more power than the cpu in the framework laptop. More thoughts: The laptop is pretty much always plugged in. When I'm out I carry a little 60W charger with me. However for other reasons I wouldn't recommend the XPS 17. I have a Lenovo legion 7 at home that I'm more happy with (cheaper, better performance, lots of ports, etc)

the one with a 17" 4K HDR touchscreen and RTX 3000 series? they will deplete the battery far quicker than the processor

Thanks for the real-world numbers! This is good for my emotional state, as I've switched from Windows to a MB Pro solely because of the battery life and performance of the M1 Pro chip.

I had similar numbers on my i9 MBP. Last week, on my M1 MBP, I spent an hour in a Teams (Electron!) call while off power and battery went from 99% to 96%. Intel needs to match that to even be in the game for portables IMO.

  The M1/M2 laptops are so above and beyond anything from AMD and Intel that it’s almost a joke. If Apple was really smart and had enough supply, it could drop the price down a couple of hundred dollars and completely take over the laptop market.

    It's already way cheaper than comparable windows machines

    Price isn't the thing that keeps most people I know away from Macbooks (after all, it's the employers/business expense). I'm sure many people would like an M1 machine for the efficiency but the software is simply not ideal. If they invested in contributing Linux drivers they'd probably be able to takeover the market for developers. Asahi is slowly improving, but it doesn't feel ready yet to be someone's sole daily machine. Ultimately my M1 MBP sits on the shelf collecting dust, except for occasional testing. My smaller and lighter Intel laptop already gets 8 hours of battery life which is more than enough for me, and has perfect Linux support.

      I suppose you mostly know ppl who run linux as their primary os then? Certainly in web dev all macs have been extremely popular.

        As someone who uses Linux daily and generally dislikes macOS, I got all my Linux tools up and running on macOS, Docker runs well and many Linux things I run on an external cluster. So I am content. The macOS UI is bit annoying and the fact that you have to install tiny apps like to have a separate trackpad and mouse scrolling direction is not ideal, but yeah it's all dwarfed by the fact I finally can't hear any fans and performance is just as good as plugged in. I can't remember when I last time had a laptop on a sofa without having to worry about the charger and getting laps uncomfortably hot.

        You don’t need separate apps to set scrolling directions for the trackpad and external nice. It’s all in System Preferences.

        They're separate tickboxes yes, but if you tick one it ticks the other. At least it did when I still used macOS on portables. Now I only have a mini left for work

    I assume the M1/M2 performance versions are much more expensive (very large L1/L2 caches, see Ryzen vs Ryzen X3D performance, and that only increases cheap L3 cache) than AMD processors. Apple can afford this I assume with high end laptop and their margins from owning the supply chain. Apple has the benefit of not telling and you can't buy an M1 (?). I would be interested about production costs of Ryzen vs. M1/M2 processors, any sources?

      Also because I assume ARM needs less transistors compared to x86 so they can use more die area for caches.

        If you look at die shots of any new chip, x86 or ARM, the actual CPU cores are taking up a smaller and smaller percentage of the die.

    The rumored 15" MacBook Air may just do that. The base M2 chip is plenty fast and with the larger case they could put an even larger battery in and push battery life to 30+ hours.

  I recently turned down a m1 mba for $1100 in favour of a 2015 mba for $500. The keyboard is so dramatically better in the 2015 model, I couldn’t believe it. The battery is great, seems to last about 10h in a charge while writing and browsing and using discord. I don’t care how fast it is as long as it continues to have those mediocre low travel keyboards. They’re better than their worst keyboards from the 2018 era but they still aren’t good

    Why not just buy a keyboard (that's better than any laptop keyboard)? There are many benefits. I always consider the built-in keyboard as a sort of emergency/convenience tool.

      I’d rather have a portable device that doesn’t need a separate keyboard

I also have the XPS 17 with i7-12700H and 4K screen. I'm able to get 8-10 hours of work (compiling Rust, several docker containers on the run, at least a dozens tabs, etc...). I'm on ArchLinux with a window manager and no desktop whatsoever. I also disabled the GPU. I wonder if there is something draining your battery on the background.

Zoom battery usage per hour should be a standard metric. Nothing kills a battery faster.
