With my iPhone 7 using iOS 14.8, recently the battery seems to have been draining much faster than usual even when the phone is on standby.
In Settings > Battery, Siri is at the top of the Battery Usage by App list and under Show Battery Usage, is at 100%.
I have never used Siri, however, and Under Settings > Siri & Search, all the buttons are white (off).
Any suggestions welcome.
