My iPhone beeps every 15 to 20 seconds

Hello ferraris,

To help us get a better understanding of the issue, we’d like to ask a few questions.

1. Does the beeping sound happen when the device is connected to a charger or accessory?

2. Does this behavior seem to happen when a certain app is open, or being used on the device? If so, which app?

3. Do any messages or notifications appear on the screen when the beep sound plays?

The above details will help us plan how to proceed.

Also, let's try restarting the device to determine if that affects the behavior. Restarting can help correct some issues. This link will guide you through how to restart, and may help: Restart your iPhone
