am not getting less noticeable time on my battery; it's certainly better than the very-first OS26 betas. just my experience here, of course...Eh… losing an hour of battery life on the M1 or M2 Air is meaningful if you tend to push those machines under Sequoia. The M3 result is weird and I'm not well read enough on the differences between the M1/M2 vs M3 to even guess as to why.
Doesn't matter to me, I use my laptop on battery only occasionally, but just because it doesn’t seem like a big deal to me doesn’t mean others won’t feel the difference.
