After I updated to iOS 15 using an iPhone SE second edition, I found that Siri doesn’t seem to respond when the iPhone is totally asleep. When I say hey Siri, The phone will wake up and read me the time. For example, I would say hey Siri turn off do not disturb. It wouldn’t answer, and I would get the response that I just wrote about. Actually, that time, Siri just beeped, is it it was finished listening to me. I hope that makes sense. Has anybody else had issues like this?
