Alarm not reliable #2822

Open cskwrd opened 9 months ago

cskwrd commented 9 months ago

Instances where scheduled alarm falls to go off. Today, a scheduled alarm went off 5 minutes late.

@cskwrd With the included Clock app or a different app?

cskwrd commented 9 months ago

The included clock app.

thestinger commented 9 months ago

Are you using battery saver mode?

LunchBoxC commented 9 months ago

I posted another thread about issues with the Alarm (in the clock app), and I had to clear the data/cache and setup all my alarms properly to get it working again. I use frequent alarms through the day for medication and I haven't had any issues since doing this. Just wanted to add to the discussion.

@thestinger No, not using battery saver.

It happened to me today. Alarm didn't even go off, got a notification half an hour later. This was the only time ever where I turned on battery saver by hand. Never used the saver mode before and everything was working as expected. Thought at first I did something stupid, since there was an extra day thanks to the leap year. Will test this a bit the next week

Just want to add, this happened to me as well on a Pixel 4a 5G bramble. Airplane Mode active, no battery saver enabled. The alarm did not go off, only a few hours later I received a notification about having missed an alarm.

I am running a two day old install of GrapheneOS, stable release channel.
