Hello, I've been using OpenBSD 6.6, and now latest snapshot, for a couple of weeks on a Thinkpad T430. Performance and stability is fine and am very much enjoying using this setup, but the battery life is unexpectedly bad, vs what I'd expect having read around OpenBSD supporting c-states and throttling.
Under OpenBSD with the system sitting idle at a GUI, WiFi active, 50% brightness I see ~15W power draw from the battery. This is with `apmd -A` and the output of `apm` showing that it is throttled to 1200MHz. The CPU fan is running at a constant low speed. Under Linux, I see an idle power draw sitting in the GUI, WiFi active, 50% brightness of ~8W. The CPU fan is mostly idle. >From reading around I was expecting more in the range of 70-80% of the Linux battery life, rather than ~50%. I understand several people may be using T430 machines with OpenBSD. Would be grateful for any info r.e. is this power draw typical, or any hints for other things I can look into? Many thanks, Dave Trudgian
