Time Left on Your Battery (Drain or Charge)

Posted in System by mosius 677 days ago

This simply displays the time left on your battery. If it's fully charged it'll display "~" and otherwise it'll display the time left until fully charged (if plugged in) or the time left until fully drained (if it's unplugged).

Script:

isFullyCharged=`ioreg -n AppleSmartBattery | grep FullyCharged | awk '{ print $5 }'`
timeLeft=`ioreg -n AppleSmartBattery | grep TimeRemaining | awk '{ print $5 }'`

if [ $isFullyCharged = "Yes" ] ; then
    echo "~"
else
    echo "$timeLeft"
fi

Cool one, thanks! Anyway, is there any way to show the remaining time in H:M format instead of minutes only?

Probably some simple "mod" math, but I didn't get into that.

If you want to break it into an hour a minute display:

isFullyCharged=`ioreg -n AppleSmartBattery | grep FullyCharged | awk '{ print $5 }'`

timeLeft=`ioreg -n AppleSmartBattery | grep TimeRemaining | awk '{ print $5 }'`

if [ $isFullyCharged = "Yes" ] ; then

echo "~"

else

((hour=$timeLeft/60))

((min=$timeLeft-$hour*60))

echo "$hour:$min"

fi

printf can be convenient in that situation too :

MIN=`ioreg -rn AppleSmartBattery | awk "/TimeRemaining/"'{ print $3 }'`;H=$(( $MIN / 60 ));M=$(( $MIN - ($MIN / 60) * 60 ));printf "%i:%.02i" $H $M

so ive been using this one, but I just had to replace my laptop battery. Now for some reason now the geeklet does not send back the same time as clicking on the batter icon. on average it off by an hour. any ideas?
