PDA-Based ETDs

[Don Mannino]

Terry,
 
A few things to check to help battery life:
 
- Turn off all wireless radios.  Bluetooth and Wireless LAN can both be
switched off and left off. If this model has infrared, you can dig in there
and disable that as well, although that doesn't have as much impact as the
wireless radios.
- Turn down the display brightness to the minimum that will work.  When
tuning you can usually work with the backlight in the lowest 1/5th area.
 
That should increase your battery time.  Most people report that they can
run all day on one charge, although some carry a car charger to refresh the
battery as they drive.
 
Some models have extended life batteries available, but I don't know if this
one does. At least not yet, since it's fairly new.
 
I don't tune all day often, but I do use the computer all day very often
when traveling, and it is rare for the battery to run out unless I needed to
use the wireless features a lot during the day.

I will be taking a first run on my new HP ipaq 111 PDA w/ Verituner software
(been using a VT100 for a few years) this afternoon. Just got the software
installed last night. Was curious how long the battery lasts, so I left the
unit on while I walked my dogs this morning and the darn thing chewed up 55%
of my battery in 90 minutes just sitting there with the display lit up.
That's going to put a severe cramp on my tuning business.
 
Anyone else care to share their experience with the battery life of these
units? I believe the Cybertuner software is often run on similar/same PDAs.
My battery is 1.2 Ah capacity. Do I need to head out in the morning with a
separate battery for each pitch raise and tuning? Is there a way to minimize
the power drain? If I am tuning, I can't have the thing going to sleep every
three minutes - I mean, I'm using it!
 
I can't believe anyone is using these things if you can only get one or two
tunings out of the darn thing before it goes dead.
