Maybe they will integrate wireless charging into the laptops soon?
When unplugged, it engages the performance cores as little as possible. You should be able to run `powermetrics` on an interval while running a high-intensity task to confirm; the performance cores pin first when on mains, then ramp up the efficiency cores, and the opposite happens on battery.
It's a big difference because the efficiency cores max out at about 2W draw, and the performance cores max out at around 18W. There's a big incentive in battery life to rely on that behavior.
I'm not sure yet if it's tunable, macOS doesn't make that a transparent behavior where you can just tweak it at will.
The Air will throttle if under full load long enough, but it's still mostly just ramping down the performance cores to stay cool.
With a true 'all day' battery, you'll probably only plug it in at a desk where tripping or knocking things over isn't an issue. While travelling, you just charge it at night or when you aren't using it. Much more like smartphone usage.
How many people are aching for a magsafe phone charger?
Just got a 16MB 500GB M1 Air and so far everything is at least as snappy as the 16" Pro, and battery looks like a full 8 hour day + so far... it's a keeper I think. I also find the keyboard a bit nicer to type on personally than on the 16", so accuracy is up.
I can't imagine how you got used to the performance you have right now. Either you are not doing anything with your device or you would hugely benefit of upgrading at least every 3 years or so.
A new laptop isn't critical to my work at the moment, so I'm happy to wait for an M2, if that's what it will be called. Looking at Apple timelines a new chip tends to be 1-2 years apart, and I'm fine with that.
I'm also reluctant to give up Magsafe, or at least have to buy a magnetic USB C connector.
