mhm... using the line from desktop command execution widget for reading the current load in mAh:

Code:

hal-device bme | grep battery.reporting | awk -F. '{print $3}' | sort | awk '$1 == "current" { current = $3}; $1== "design" {print current "/" $3}'

if you want to store it in a file use > (overwrites) or >> (appends).

possible script:

Code:

#!/bin/bash

# creating endless loop
while [ 1 ]; do

  # print date and time
  echo -n $(date) >> /home/user/MyDocs/battery_raw.txt
  # print some text in between
  echo -n " - mAh: " >> /home/user/MyDocs/battery_raw.txt
  # print "current/full-charge"
  echo $(hal-device bme | grep battery.reporting | awk -F. '{print $3}' | sort | awk '$1 == "current" { current = $3}; $1== "design" {print current "/" $3}') >> /home/user/MyDocs/battery_raw.txt

  # sleep some time (in seconds) - for example 5 minutes
  sleep 300

done

this should make a file called battery_raw.txt (extension txt just for easy use in windows ^^) which you can copy over to your pc when the phone is connected via usb. (:

the battery_raw.txt file should look something like:

Code:

Thu Mar 4 00:24:06 CET 2010 - mAh: 1022/1265
Thu Mar 4 00:24:11 CET 2010 - mAh: 1022/1265
Thu Mar 4 00:24:16 CET 2010 - mAh: 1022/1265
Thu Mar 4 00:24:21 CET 2010 - mAh: 1022/1265

for test/preview purposes i changed the sleep time to 5 seconds ^^
(and yep... you could write all commands in one line... but i wanted to comment what the commands are doing *g*)

copy the battery_raw.sh over to your phone - for example in the documents-folder.
then you can open xterm and run it via

Code:

sh MyDocs/.documents/battery_raw.sh

minimize it and it will make one line every 5 minutes

(of course you can change the sleep time *g*)

edit: attached the file ^^
