Notices

I would like somthing to make it so i don't have to light up the screen to know how much battery charge is left.


The way i picture it is, instead of the pre-generated pattern for the status LED for the idle state (when the screen is locked and the N900 isn't plugged on the charger), the LED would blink first in a reference pattern (so you know what full would look like) and then in a pattern representing the current battery charge (or if that would use too much charge, check the battery charge every N minutes and update the pattern when it has changed since the previous measurement), at aproximatly the same rate as the default pattern (i mean, about as many repetitions per minute)

I too would like this. There are many possible alternatives to what LED patterns to use, so being able to choose would be fantastic.

I have no idea how to go about this though...

what about a blinking LED that blinks lets say every 15 sec
and the intensity of the LED or how strong it emits light is the indicator

or

a green LED when from 100% to 70% and yellow from 70% to 20% then red when less
that would be much more accurate

The LED is capable of 256 levels for each color component, you could for example have it change it's hue going across the rainbow, purple for full charge, then gradually turning blue, then gradually cyan, then gradually green, then gradually yellow, then gradually orange and then finally red; or really any color gradient (could for example go from white to yellow to orange to red to dark red to black, like a piece of metal made extremely hot and then cooling down in the dark)

it's a nice feature to know how much battery is left even from a long distance and in the dark

just do it

lol, sorry i didn't research the colors of the rainbow before posting, apparently it was necessary

If it were me, I'd tie it into the 8 "bars" information that is already there. Allow the user to change how frequently it update N minutes as suggested.

I would set it up like so:
3 green blinks = 8 bars
2 green blinks = 7 bars
1 green blink = 6 bars
3 yellow blinks = 5 bars
2 yellow blinks = 4 bars
1 yellow blink = 3 bars
3 red blinks = 2 bars
2 red blinks = 1 bar
1 red blink = 0 bar

It would be easy to quickly tell the approximate charge level at a glance. Refresh the pattern every 10 minutes or so (pick a number to suit yourself), update to a predefined pattern, repeat.

Only problem is any notifications would overide this, unless the priority is set high enough.

this probably is next to impossible to implement. that probably requires killing MCE led blinking completely because of conflict between MCE and requested app trying to drive the same controller
