Pre-covid, I traveled for a living. Overseas 2x a month + lots of domestic trips. I was almost always in range of a power outlet personally:
- Home office (outlet)
- Airport Lounge (outlet)
- Plane (outlet)
- Hotel (Outlet)
- Conference room (usually outlets or the damned conference room recessed ones). I took a 6 inch extension cord for these as many didn't allow my small gan PD adapter to fit in.
- Client site (outlet)
So while having good battery is nice for when I'm too lazy to plug in (or occasionally working on a deck while ubering to the airport)... 6-8 hours is plenty for me. I prefer raw computing power over battery efficiency.
Now weight... that is significant for me. I was waffling between M1 MBA and the new 14 inch MBP mainly on the issue of weight. I carry everything with me for 1 day to 1 month trips in a single 26L backpack... so weight is a biggie for me.
