Ding sounds for no apparent reason

Are you getting an alert of some type from one of your apps? You might try going to the notification center (swipe down from just above the clock/below the ear) to see if there are any notifications there. To get out of the Notification Center, swipe up.

You could also go to Settings/Notifications to see any apps that are potentially giving notifications.

Sounds for Native apps are controlled in Sounds. Sounds for Apps you install are controlled in Notifications. If you go to Settings/Notifications, you can see what apps are configured to give a sound. If you don't have any recent notifications in the Notification Center, you might have to go through Settings/Notifications and turn off apps with sounds that are on, in a process of elimination. It would have been great if you had a notification in the notification center that had alerted you recently, that would have lead you to the culprit.

Hello... I had this maddening thing happen with my iPhone 4s, and it took me a long time to get it rectified. I have had my iPhone 6 for just a little over a year and yesterday, the same thing began happening again. The bad thing is, I could not remember how I solved the problem with my 4s! The solution turned out to be that my charging cord needed to be replaced... it was a simple as that. The cord looks fine... but it began to not charge my phone, which is how I figured it out.

Hmm, interesting. I wonder if there are differences based on carrier? I have AT&T and I don't have an option in Notifications to turn all notifications off the way you describe above. But yes, if you turn them off (assuming it's an app that is alerting you), and then turn them on one by one you will hopefully find it.

I think I've solved it.

I just read this thread after googling for an answer about this topic.

I'm sure it's the Gmail app notification sound (that's the case for me anyway). The "Ding" means you have a new email... I've tried it 4 times and it is indeed the case.

Patricia... you are so very welcome! Hopefully, I will remember this solution the next time it happens! I just wish I did not have to replace the cord so often. I am very careful with them, so I think they are not made very well. This is my FOURTH Apple charging cord in three years.

In case you haven't figured it out, which you mostlikely have, or if you're having this problem I just found out what was happening. It's your emails. Even if it doesn't send a notification. I found this by going to settings>notifications and then going to mail. The notif sound was ding and none of the others where. That's how came to this conclusion

I Have new cords now, but for some reason cord must be "loose" when plugged into iPad, ??? and charging still stops & restarts with a DING when I move charging iPad around.

However, for me the DING is definitely caused by charging being started.

i Watch the battery go to black, then green with a DING.

Thanks so much, never would have figured it out!

Thank you!! This is exactly the problem. When my phone is plugged into the bad charger, my phone dings intermittently. If I watch the screen, I can see the battery charging indicator switch from green to white then back to green every time there is a ding.

Is "ding" the sound you device makes if connected to the computer? If yes, did you check your USB connection/cable if connected?
