There is, but not for Maemo 5 at the moment ;) Porting is in progress ;)

Nice nice. Will have to get it once it is ready.

Thanks for the useful post...

Have you found anything that shows the charging current? I have been trying to compare the rate of charge of the supplied charger and various other chargers (using the supplied CA-146 adapter).

"hal-device bme" shows charger type when the device is being charged. It might have some hints on the maximum charging current the device will try to draw.

Do note that Li-Ion batteries are charged with fixed current to 60-70 % charge and after that with fixed voltage to 100 %. The first stage on a fast charger is something like 40 minutes and the second stage will last somewhat over an hour. As such, a slower charger (or heavy usage while on fast charger) mainly affects the first stage only.

Battery charge percentage is taken from current charge level divided by design charge level. Thus, the display is only 100 % when it is all new. With time and use, it will be lower and lower at fully charged state.

And the fully charged level may vary by at least 5 % between 2 sequential charges. As such, a single reading isn't too reliable. Thus, you might get 95 % next time you charge it.

I was successfully using the command "lshal grep | percentage", but now the terminal replies "-sh: percentage: not found"

What is going on here?

Thanks!

Try: lshal | grep percentage

Is it possible to get a "battery usage application" like the one on the DROID? Where it shows which app/process is using % of drain:

Would be neat to have a widget that replaces the normal battery bar with battery charge percentage number.

been reading this thread and ive got some nice suggestions in this thread.

Anyways there is another threadHERE - a desktop widget to show the percentage of battery but its not yet integrated into the status bar, currently it resides on the home screen.

have taken some inputs from this thread will see if I can incorporate it.

cheers
