If you’re like most people, you probably have a lot of notifications going on in your phone. But if you want to increase the notification volume on your iPhone, there are a few things you can do. First, make sure that your notifications are set to “sound off.” This will stop all sound from coming through when a notification is received. Second, change the volume of your notifications. You can do this by going to Settings and selecting “Notifications.” Then, select the “Notifications” tab and change the “Volume” setting to something higher than “0.” Finally, try turning off vibrate on your iPhone. This will reduce the amount of noise that is made when a notification is received.
