Bug Description

If airplane mode is enabled, the phone seems to go into a deep sleep where it doesn't wake up for a calendar reminder. The reminder does not sound until the power button is pressed to wake the phone, in some cases this has been more than an hour after the reminder was scheduled for.

Seems the calendar events should also set an alarm wakeup.
As described it is relying on the 5 min polling wakeup which does not happen when all the radios are off.

Also, the alarm clock doesn't go off if in airplane mode.

@charles can you comment, do we set an alarm to wakeup or rely on a timer?

Pat, yes we use the com.canonical.powerd interface's requestWakeup method to wakeup the phone when a clock alarm or calendar event needs a notification.

indicator-datetime doesn't have any airplane mode logic in it at all, so I'm not sure what's going on there.

I'm not able to reproduce this on a n4 running 15.04 (r531) by turning on airplane mode and trying calendar events and a clock-app alarm. Is this issue reproducible for anyone?

Since filing this bug, the issue has only got worse. It has been 100% reproducible for me for the past couple of months. I have a calendar reminder to go off at 8am. Every morning, it only goes off when I actually wake up the phone myself, in some cases this has been over an hour past the time it was supposed to remind me. The only time it successfully works, is if I have woken the phone a few minutes early (presumably the phone doesn't go back to a deep sleep for a few minutes or something).

And, that's also on a Nexus 4, using the stable releases. Failed again this morning on OTA-13.

These seems specific to the Nexus 4, moving to backlog as it is no longer actively supported
