Push-client should be disabled when in flight-mode (no network connection), as it makes no sense to wake up the phone at every 5 minutes if we know the check will fail.

The system should be smart enough to enable the push-client service only when there is a valid connection (either 3g or wifi).

After manually stopping push-client and enabling flight-mode, my battery consumption reduced quite a bit, as it was in deep sleep during all the period I had the screen turned off.

Status changed to 'Confirmed' because the bug affects multiple users.

[Richard Somlói (ricsipontaz)]

I agree with this. Push-client should be disabled when mobile data and wifi are turned off too.

[John Lenton (chipaca)]

Disabling push client at the moment would also disable the postal service, which we wouldn't want to do i don't think. At some point those two can (and possibly should) be split, but not for now. In view of that, we could either expose an interface to tell us whether to wake up the phone (to be called when entering and leaving flight mode), or monitor flight mode status from push itself. The latter shouldn't be hard, as long as it's exposed either as a property of network manager, or by the AccountsService dbus thing (we're currently tracking properties from both of those, so adding another property would be fairly straightforward).

(marking incomplete until we learn how flight mode is exposed)

[John Lenton (chipaca)]

So, flight mode is exposed via dbus on its own interface (org.freedesktop.URfkill.IsFlightMode and its FlightModeChanged signal). This is more work, but still doable I think.

If we were to interface to urfkill, and enable the polling when not in flightmode (and disable it when in flightmode), that would be sufficient, yes?

[Ricardo Salveti (rsalveti)]

As discussed over IRC, we just need to handle the situation where the user enables flight mode and then manually enable wifi.

We don't yet have an API for this it seems, but everything goes via urfkill, so there might be the way to go.

dbus-send --system --print-reply --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.DBus.Properties.Get string:"org.freedesktop.NetworkManager" string:"WirelessEnabled"

will get you the info if wireless is on or off ... (just translate it into whatever language your app uses)
