Clock app warns "battery saver may degrade your alarm experience" — exactly what degradation might I expect?

On my Moto G22 running Android 12.0, with the stock "Clock" app (com.google.android.deskclock Version 7.10), when I set an alarm or a timer while battery saver mode is switched on, the Clock app issues a warning: > Battery saver may degrade your alarm experience. I always use battery saver (unless my phone is charging), and neither the alarm nor the timer has ever failed me. How exactly may battery saver "degrade [my] alarm experience"? Does it affect some fancy features that I don't use? Or is this warning essentially incorrect? I found [several](https://www.boards.ie/discussion/2058250500/alarm-clock-battery-saver-may-have-degrade-your-battery-experience) [web](https://www.reddit.com/r/GalaxyS23/comments/128mpj6/battery_saver_may_degrade_your_alarm_and_timer/?rdt=36755) [results](https://brainly.com/question/32168966) , none of which were helpful.
