Was wired network connected while the sleep period? If yes, could it be
that wake on LAN was enabled, and the link is Gigabit Ethernet? I don't
know if this really matters, it's just a guess. I read that a gigabit
link eats a lot of power.

You could also check if other devices had wakeup enabled:

$ find /sys -name "wakeup" |xargs grep "enabled"$ find /sys -name "wakeup" | xargs grep "enabled"
