[Bug 1434637] Re: Default alarm behavior can cause unnecessary battery drain
Specification updated.
** Description changed:
As discussed in private bug #1430666, the default alarm ring duration of
30 minutes is really long compared to other phones. This got called out
because it will cause unnecessary screen-on battery drain.
IMO 30 minutes should not be the default option -- if a user doesn't
dismiss after 10 minutes, adding another 20 feels like overkill.
In addition, datetime (rightly) turns the screen on when an alarm
triggers. It's kept on for the duration of the alarm, even if it rings
for a half hour. That's a pretty long screen-on time to pay when the
user's inactive.
- So, two questions.
-
- 1. Can we change the default alarm duration from 30 minutes to something
- shorter, e.g. 10 minutes? The 30 minute default is specified in
- <https://docs.google.com/a/canonical.com/presentation/d/1JvDyhsW17d1-Mz8OY1YMBKwfRI2z9qgyRjbujEsxEMk/edit#slide=id.g36c1a0cdd_010>.
+ 1. <http://goo.gl/onnFLb>: "‘Stop ringing after’ controls how long the
+ timer rings. It is set by default to 10 minutes and can be changed with
+ the expansion component"
2. Datetime should release its "screen on" hold after the first few
minutes, so that even long-ringing alarms don't drain more battery than
necessary.
