Power saving mode is a must :) To activate manually and automatic settings depending on the battery life.


A customizable power saving mode could/ should have the following features/ settings which you could choose from how your (personalized) power saving mode should act like if activated:

  • time- and batterystate- settings for a personalized activation of PSM
  • dim display brightness
  • trim back connections (switch off "always on"-type of connections, do not sync mails, etc.)
  • ability to use only 2G instead of 3G/4G
  • turn the display into grayscale [also maybe with black background like on N9] (would make more sense with a AMOLED screen -> hopefully for Jolla 2)
  • deactivate unnecessary features

What would this entail in practice?

I guess it could be something pretty similar than on N9 or other similar phones: dim brightness, trim back connections (switch off "always on"-type of connections, do not sync mails, etc), switch to 2G instead of 3G, etc.

Should be added but no way as a priority demand. As for now, the battery life can be up to 500h which should be enough.

500h if you don't use it at all, sure. But the battery doesn't last a whole day on average use. That's where it counts. I think something must be done regarding battery consumption and I think this is definitely a high priority demand.

Fix the NFC and it will

I agree that its needed, but not that it should be something that's not-automatic by default. For example, power saving should automatically kick in - with a notification explaining what's happened and what's not as usable after a device gets under 50% (yes, that's aggressive, but am thinking about when most of you have had your device(s) so long the battery is no longer as good as new). Inactivity (more than 1hr) should also cause the device to go into some kind of power saving mode automatically. In this way, something like going to sleep (not a nap, but sleep) would be a trigger for the device to cut back its power (hey, we do it, why don't our "smart" machines). Once that's there, either putting some kind of API to it that apps can/should use (under prescribed conditions) can start to make SailfishOS/Jolla native apps to stand apart from Android-imports.

While the screen is off, there's already pretty aggressive power-saving going on, as the device enters a deep-sleep where everything is frozen.
