QtBatteryWidget: battery voltage, charge, temperature and time left on your dekstop
 

Hi! :)

QtBatteryWidget is just another battery widget for the N900.

It can display: voltage, charge, temperature and time left.
In the settings window you can choose the informations to display, the type of percentage (module bq27x00, standard or dr_frost_dk based on his battery meter widget), the percentage style (graphical, standard progressbar or textual) and the widget opacity.

The percentage and time left are updated when a dbus signal is emitted by the system, so time left can take some time to update.
If you want to update it click on the widget.

The time left is based on actual consumption (only if module bq27x00 or the command i2cget is present) or from the last percentage change.

The battery's graphic was made by Joppu

Just installed....looks cool...Nice work mate....however how is the value for "Time Left" calculated??? It's showing some value which does not make sense....(06:26 for battery at 68%)...what deos this mean....???:confused:

Re: QtBatteryWidget: battery voltage, charge, temperature and time left on your dekstop
 

yeah...mine says 14.57 in time left with 72.9% battery. can't be 14 minutes right? but it can't be 14 hours too right?

Re: QtBatteryWidget: battery voltage, charge, temperature and time left on your dekstop
 

It's based on the actual power consumption, if you put the n900 in standby, wait some seconds and recheck the widget it will display a different value (mine is more than 48h with 72%).

It should display the time left depending on what you are doing with the device ("time left if you continue to do what you're doing").

I don't know how much precise is the power consumption value (taken from /sys/class/power_supply/bq27200-0/current_now or /usr/sbin/i2cget -y 2 0x55 0x14 w)...

Nice work ahem utilizing my graphics without even asking. Not that I am complaining or anything.

Re: QtBatteryWidget: battery voltage, charge, temperature and time left on your dekstop
 

Ops, sorry. I forgot where I found that battery graphic (I thought I found it with google, maybe I'm wrong).
I'll add a note in the about screen, or I'll remove it if you don't want me to use it.

Looks nice, but uses just a little too much cpu for me (about 1-4%).
It would be acceptable for a program, but not for a widget constantly in the background (in my opinion that is).
Do other people experience the same cpu usage?

It's the Qt progressbar, I cannot do anything (maybe I can try to use only images avoiding QProgressbar).
4% can happen when it's updating data; the preogressbar should take from 0.75 to 2/3%.
Try to set the textual style.

mine is using between 0 and 0.2% cpu and 2.3% mem

edit: in textual mode.

Re: QtBatteryWidget: battery voltage, charge, temperature and time left on your dekstop
 

Yep, switching to text mode definitely makes a cpu-use impact (in a positive way).
