I have not seen the following matter on led notification time for emails and sms ... So:

After received email or sms, could it be possible to set the blinking time of the LED light? The alternatives could be (1) not Limited or (2) at maximum three hours.

Eg. if you received the message in the morning (8 am or so) and you can read the message just in the early evening (5 pm or so), thus the LED has blinked 7 hours continuously. I have notice some power consumption for that. At least the previous Nokia phones had this. How about with Jolla then?

Neither the N9 nor the N900 had that feature out of the box....

It has been possible since maemo days to configure led patterns to stop automatically after N seconds and this legacy logic still exists in Jolla phone too. However, it has never been used by default and might not work fully as expected. And it was never updated to take suspend into account - which basically means the timer advances only when the device is active and thus then configured limit is just lower bound for disabling.

Still, even without any sw modifications it should be possible to use auto stop for charging & battery full notifications (the device will not suspend while connected to a charger). Also - by opting to use sw breathing also when charger is not connected - any breathing led pattern can be made to stop automatically (breathing blocks suspend too).

For example: To make charging pattern stop after 5 seconds, do as root:

  1. printf "[LEDPatternHybris]\nPatternBatteryCharging=50;4;5;0;0;7f7f7f\n" > /etc/mce/90custom-led.ini
  2. systemctl restart mce.service

To restore default behavior:

  1. rm /etc/mce/90custom-led.ini
  2. systemctl restart mce.service


Just a note: Nowadays the led pattern timeout uses suspend aware timer. So it should be usable for all led patterns.
