Public bug reported: up_device_changed_cb iterates over all devices every time it's called. It is passed the device so this is unnecessary work and will result in a lot of dbus traffic. You should just look at the device which you've been told has changed.
With https://code.launchpad.net/~pitti/powerd/upower0.99/+merge/240141 we're getting upower 0.99 support. One of the new additions to the 1.0 API you get with this version is proper notify signals for properties on UpClient and UpDevice. powerd should be refactored to only listen to property changes in the properties it is interested in. This will result in more efficient code and a process that is only woken up when it needs to be, and it will be nicer as it will then be properly event driven.
