This is exactly why OpenBSD, in my opinion, is currently failing at their stated goal of "Provide the best development platform possible." (as 'stsp stated).
If you get poorer battery life on a platform and still use it, you are doing something very contrary to like 99% of all laptop users, including developers. Now I'm fine if OpenBSD says "We don't care about that, we're a server OS", but there should be some big red stickers saying "We have terrible battery life on laptops" on the BSD websites.
