I tried removing the SD card. I now show... no battery drain at all (which is a
little suspicious - still at 100%). Plucker appears innocent here - a good
thing as it's a truly key app and irreplacable to me. Assuming that was the
cause I don't understand the SD card issue - the card works fine, and sometimes
there's no problem when it's inserted. I should think the card circuit would be
entirely off when the TX is off.
At this point I'd say it's possible but not proven it's the SD card.
"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. " -- agreed,
though I've heard that when a device is new the batt should be given a few
(3-4) cycles down to <20%. I wonder if that helps calibrate the battery meter.
thanks for following along with this

OK. I have IR ("beam receive) and BT off, as well as BT discovery (would bothe
polling?). Screen is set to minimum and auto-off to 1 min, and I don't use
autolock (I did install the fix). It is difficult to assign a cause to this
simple problem, but I may have a found a cause/effect.
Condensed:
Leave handheld on overnight with SD card out ==> power drain as shown on
handheld ===> drops approx 5% overnight (varies on different 8 hr periods.)
Replace SD card back into TX, open Plucker (prc was on card) and view docs
===> drops from 81 to 61% overnight.
So, either the presence of the SD card or the use of Plucker caused it. I
had intended to test one variable - use Plucker - but it's installed partly to
the card and partly to the TX (there's 2 pieces). So, for a quick test I've
just i. Used Plucker again ii. Removed card (on which plucker was installed).
btw, to move something (such as Plucker) between the card and TX can I just
copy and delete?

Hi -
I'm chasing a power drain with my TX - it often draws down 30% overnight while
off. Is there anyting in Plucker that could be doing this?
thanks

No, but IrDA and Bluetooth polling certainly can. Check that, and make
sure your screen is set to turn off after a small amount of time, 30
seconds or less should be sufficient.
There's also a reported issue with the "autolock" feature of the TX
causing rapid battery drain. Try this URL for tips and ideas:

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:
http://www.geocities.com/SiliconValley/Horizon/9959/
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.
