I got some 20 hours out of my M1 Air when I tested it after the first full charge. Then I decided to charge it. Calculated at various points that it would last roughly 25 hours and it sure seemed like it was going to.

Much of this time I had Xcode running and videos playing, etc.

Subsequent charges never lasted this long because I installed more bloat, but still always over 10 hours even when I had a bunch of shit running.

This wasn't about arm in a high end laptop though, this is about underpowered cores in an soc probably meant for sbc applications barely managing out of order execution shoved into a laptop form factor.

I'm not against riscv on principle, in fact I quite like it. But let's not pretend it's performance is there yet for laptop-class devices.
