I have a Tapwave Zodiac 2, which is a PalmOS 5.27 device. I
have
Plucker installed, with about 3,000 Plucker documents
occupying about
1.4GB of a 2GB SD card. I have seen *no* evidence of impact
on
battery life from using Plucker.
At the moment, Plucker is in RAM, since the Zodiac 2 has
128MB of RAM
and I can afford to keep it there, but I have also run
Plucker from a
card on my older Handspring Visor Deluxe, Visor Pro, and
Tungsten E
devices. Again, *no* battery impact I could see.
Battery power in consumed when something is running on your
PDA.
Screen brightness is the biggest usual variable. The
brighter the
screen setting, the more power is consumed. Wifi is another
huge
power drain, and BT and IR can also use power. I seldom use
Wifi, and
almost never use BT, and I keep IR receive off unless I
anticipate
getting beamed something. I use a freeware app called Blue
Fang to
assist with BT: you can specify rules governing BT usage,
turn BT on
automatically when you run something that needs it, and turn
BT off
again when the app that uses BT exists. You can find Blue
Fang here:

I don't see how Plucker could be responsible for your
battery drain.
When it isn't running. it isn't consuming power at all.
When it is
running, it's using the same power as any other
application.
I'd test again by replacing the SD card in the PDA, but
*not* running
Plucker. Do you still see the battery drain?
Personally, I leave my Zodiac charging at night. All the
info I've
seen indicates the best battery life if you keep your PDA
"topped up"
whenever possible, rather than letting it discharge. In
normal daily
use, I see the cahrge from from 100% in the morning to
perhaps 80% in
the evening. Since I top off nightly, I don't care.
