if you turn on power saving mode when you’re doing light tasks the laptop runs forever at 50% brightness.
I find myself doing that like twice a month so it’s not a concern at all, battery life is phenomenal for the power these machines have while producing minimal heat and being completely silent.
The battery life is amazing with lightweight workloads. Unfortunately when doing anything more it becomes fairly mediocre. With my normal dev work it lasts about 2-3 hours at best.
on Max or Pro chip?
Yeah, Apple's secret sauce isn't necessarily perf/watt in an all-core load (although they're obviously near the top there as well) but in idle power consumption. I'm guessing that M3 does better here, but I remember seeing a Phoronix test/review that showed that when capped at 15 W, the latest Ryzen laptop CPU beats the M2 in all-core workloads, although the M2 gets better battery life in "normal" workloads.
You running a ton of containers or something? I have a fairly intensive set of Docker containers running at all times and still usually get a full-ish work day out of my M1 Pro MBP
I usually get around 10 hours doing front-end dev and design work.
