Limit Your iPhone’s Volume

Besides allowing you to see your volume level from the media player, Apple also added a helpful feature called Volume Limit.
As you can guess by its name, this feature will help you limit the maximum volume of your iPhone’s speakers. Here’s how to set up a volume limit:
- Open the Settings app.
- Scroll down and go to Sounds & Haptics.
- Scroll down again, and under Built-In Speaker, tap on Volume Limit.
- Turn on Limit Maximum Volume.
- Adjust the slider to choose the Maximum Limit you want.
Note that this feature will only limit the volume of music, videos, and other media types. It won’t limit the volume of your notifications, alerts, alarms, or Find My sounds.
