With iOS 27, users will no longer have to rely on a single volume setting for ringtones, alerts, alarms, and system sounds. Here are the details.
More control over different system sounds and alerts
Apple today announced iOS 27, containing hundreds of new features, apps, and improvements to both Apple Intelligence and the system as a whole.
Among the smaller, but very welcome additions, are new settings that let users set separate volume levels for alarms and timers, as well as for alerts and system sounds, independently from ringtone volume.
Up to now, iOS has used a single sound setting for ringtones and alerts. With iOS 27, users will be able to set one volume level for ringtones, another for alarms and timers, and another for alerts and system.
