Someone correct me if I'm wrong, but this is what Steve is referring to. 30 days of standby effectively makes awake from sleep the same as on, whereas before you had a fast drain during even sleep.
- borism 16y agoI wouldn't call several days or almost a week of standby with a healthy battery a "fast drain". Nobody on HN leaves their computer sleeping for more than few hours anyway, right?
- gamble 16y agoThe '30 days of standby' figure assumes that you let your Air go into hibernation, which has been supported by MacBooks for a long time, but only as a last resort when the battery gets low. The Air is apparently just more aggressive about using hibernation. The underlying power management architecture (top-notch, admittedly) hasn't changed at all. Hibernation isn't any faster to restore than other MacBooks with a SSD. They've just made wake-from-sleep slightly faster on the new Air. Nice to have, but it doesn't seem as significant to me as Steve made it sound.
- ericd 16y agoAre you sure about this? Hibernation generally refers to writing the contents of RAM to disk so that the computer can power off completely, if I'm not mistaken.
- gamble 16y agoThat's what Engadget is saying is necessary to hit the 30 days. It's still early and no one has had time to do a thorough review, but I don't get the impression that there's anything fundamentally different about the new Air's power management. They've just tightened up the response time and made the SSD standard, so hibernation is much faster.
