GoKawiiliOS 27 lets iPhone alarms stay loud independent of ringtone volume
Apple's iOS 27 update adds a new toggle in Settings under Sounds & Haptics called Match Ringtone Volume, found in the Alarms & Timers section. Turning it off reveals a separate slider so alarm and timer volume no longer changes when you adjust your ringtone volume, and a similar option exists for system alerts like notifications and keyboard sounds.
