PDA-Based ETDs

[Porritt, David]

Terry:

 

The biggest drain on the battery is the light.  Dim the light as much as
possible and still be able to see it (you really don't need it as bright
as most people use them if you're indoors.)   I've had two iPAQs and
just last week got a Samsung i760 phone with PDA.  I've worked all day
with it and had no battery problems.  The other problem with this is
that I work a good share of the time in an area that gets no cell phone
signal.  The phone keeps pinging to try to find a signal and that drains
the battery a lot.  But, with the "extended" battery on this Samsung
unit I'm getting a full day of service from it in spite of the constant
pinging for a signal.

 

I'm using TuneLab Pocket as I have for years and I don't know if that
makes a lot of difference on battery drain but it might.  By the way, I
really like the i760 phone/PDA!

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.
