I once had a problem with a new Xiaomi phone where the OS would put the clock app to sleep and the prevent it's background activity, missed 3 alarms before figuring it out.
I had the same issue, but i was using a third party app because i don't really like the default one and a year later the problem started, now i am forced to use the default app if i don't wanna my boss waking me up again
You can disable the optimisations for specific apps, should be under battery settings. At least that did it for me.
I did the day i installed the app, i really don't know why it stopped working
Never an issue for me
I've had a similar issue on android, where the alarm is late. Shortest, but still late, was 3 minutes, and longest was for over an hour.
What the heck? That's pretty bad and kinda defeats the point of an alarm.
Are you using an alarm that tries to track your sleep?
Nope, standard alarm with the default clock app on my phone.
Your device is faulty. If it's new enough, seek a fix via warranty.
Um no it could just be that the battery saving options are just not letting it run in the background
Battery saving shouldn't affect the built in clock's alarms
It definitely will
Could be internal damage. At least, that was the case with my old phone.
Ive had this issue on multiple iphones and android phones its contributed a lot to my lack of trust in electronics
Samsung timer app has alarms fine, but the timers have no sound
