If you can repeat it on a -current snapshot, yes please.

"power-saving" with 802.11* is where the AP buffers frames for clients
so they don't have to turn on their receiver so often (they turn it on at
certain intervals so they can learn if they have to leave it on for longer
to receive any buffered frames). There are a couple of different specs,
an older one that many devices support, and a newer 802.11e WMM-PS one.

It's not necessarily connected with whether or not a device is on battery
power.

Other devices in the local area might do it too. (And some devices turn
on power-saving mode without a way to disable it e.g. Blackberrys and
I think some iPhones).
