Why is my phone making a chirping sound?

A chirping or beeping sound on a mobile phone can be alarming and concerning for many users. This intermittent chirp is often described as a high-pitched beep, similar to a bird call or the noise made by a smoke detector when its battery is low. The abrupt, unexpected sound can happen suddenly during a phone call, while using an app, or even when the phone is idle.

There are a number of potential causes that can produce this odd chirping noise. This article will explain some of the common reasons a mobile phone may make a chirping or beeping sound, from hardware and software issues to environmental factors. Identifying the root of the problem is the first step to silencing the chirp and regaining normal function.

Low Battery

One of the most common reasons a phone may make a chirping sound is due to low battery. As the battery level gets critically low, the phone will start to conserve power by limiting background processes and push notifications. It will also trigger warning sounds and vibrations to alert you that the battery needs to be charged soon.

The chirping is the phone’s way of urgently signaling that it is running out of power and trying to conserve its remaining battery life. The sounds may get louder or more frequent the lower the battery level gets. It’s the phone’s last resort to grab your attention before it shuts down from lack of power.

If you start hearing chirping sounds, check if your phone’s battery level is at 20% or less. Try plugging it into a charger and see if the chirping stops once the phone begins charging again. This confirms that the issue was simply caused by a low battery.

Alarm/Notification

Phones often make chirping noises for alarms and app notifications. Many apps like calendars, email, and messaging have chirping sounds built-in as notification tones. Popular apps like Facebook, Instagram, Twitter, WhatsApp, and dating apps like Tinder and Bumble allow users to customize notifications with chirps or bird sounds.

Chirping notification tones have become very common, especially for text messages, emails, and app alerts. Sounds like bird chirps, whistles, dings, or beeps are often used for notifications to gently grab the user’s attention. Phone manufacturers like Samsung and Apple include a variety of chirp and tweet sounds users can choose from to assign as custom notification ringtones.

If your phone chirps occasionally, it’s most likely due to a notification from an app or built-in calendar/alarm function. Users can customize or disable these sounds in the phone’s settings or app notification settings. Chirping notification tones aren’t a cause for concern and can be changed if desired.

Hardware Issue

The beeping sound could indicate an issue with a hardware component inside the phone [1]. Common culprits include:

  • Faulty speaker – If the speaker is damaged or disconnected, it may emit beeping noises.
  • Bad vibration motor – The vibration motor uses a small oscillator that can malfunction and cause beeping.
  • Disconnected wire – A wire that has come loose could cause an intermittent beep.
  • Corroded contact – Moisture damage can cause corrosion on the contacts, leading to beeping.
  • Damaged headphone jack – Issues with the headphone jack wiring can cause beeping sounds.

A hardware problem indicates a physical defect or component failure inside the phone. The beeping is the phone’s way of signaling there is an internal hardware fault. Unless the issue is repaired, the beeping is likely to persist and potentially worsen over time.

Software Glitch

Sometimes a software glitch in the operating system can cause improper audio playback, leading to strange chirping or beeping sounds from your phone. This tends to happen most often after a major Android OS update. Bugs in the new software can disrupt normal audio functionality.

For example, some Samsung and Pixel phone users have reported a “bird chirping” sound randomly occurring after recent Android updates (Source). The chirping happens even when no notifications are active. This points to an audio glitch within the OS. Restarting the phone may temporarily fix it, but a permanent solution requires a software patch from the manufacturer.

Glitches like this highlight the need for extensive software testing before major OS updates. But even with rigorous testing, bugs inevitably slip through. If you notice odd sounds after an update, check online forums to confirm it’s a widespread issue being worked on rather than an isolated problem with your device.

Interference

Electromagnetic interference from a phone being in close proximity to speakers is a common cause of chirping or buzzing sounds. This happens because the radio frequencies emitted by the phone can induce an audible signal in the speaker wiring and components. According to sources like Reddit and SuperUser, keeping the phone away from the speakers and cables can help reduce this interference noise.

As explained on TechTarget, electromagnetic interference (EMI) occurs when “radio frequencies generate a signal in unshielded audio wiring.” The wiring acts like an antenna, picking up these unintended signals. Phone frequencies in particular are prone to causing speaker interference since they fall within audible ranges. This is why phones placed near speakers often cause chirping or beeping noises to be heard through the speakers.

Moisture Damage

One of the most common causes of a chirping sound from your phone is moisture damage, especially to the speaker and microphone components. If water or liquid gets inside your phone, it can cause short circuits and corrosion on the delicate electronics. As water evaporates, it can create intermittent connections that make chirping or buzzing noises.

According to ifixit.com, if your phone got wet, you should immediately power it down, remove the battery if possible, and allow it to dry thoroughly before turning it back on. Any remaining moisture inside can continue to damage the electronics and cause issues like chirping sounds (Source).

Liquid damage often requires professional repair to fully dry out and replace any corroded components. But the chirping noise itself is a sign moisture is still present, and you should avoid using the phone speakers or microphones until it can be inspected and fixed.

Outdated Operating System

One potential cause of a chirping sound from your phone is an outdated operating system (OS). As phones and OSes are updated over time, older versions may develop audio glitches. For example, some users have reported hearing odd chirping or beeping sounds from iPhones running iOS 13 or earlier [1]. Outdated versions of Android can also begin exhibiting audio issues like chirping.

The reason this happens is that new iOS and Android updates include bug fixes, optimizations, and improvements to system resources like audio playback. Older operating systems lack these updates and may start having problems over time. The chirping could indicate an audio resource on your phone is not being properly accessed or is experiencing latency issues.

Updating your phone’s OS to the latest available version can potentially fix chirping and other audio problems. This ensures you have the most up-to-date software, including any fixes to system resources related to sound playback and notification noises.

Summary

My phone’s chirping sound could be caused by several different issues. A low battery charge, alarms and notifications going off, hardware problems like a faulty speaker, software glitches, wireless interference, moisture damage, or an outdated operating system can all lead to odd chirping sounds from a phone.

To recap, the main reasons covered for a chirping phone sound are:

  • Low battery power causing the phone to emit warning beeps and chirps

  • Alarms, calendar notifications, or other alerts set to make chirping sounds

  • Hardware issues like a damaged or faulty speaker

  • Bugs, crashes, or errors with apps and software

  • Interference from other devices, weak signal, or bad WiFi connection

  • Moisture buildup or water damage inside the phone

  • Outdated operating system unable to support newer ringtones or sounds

When to Take Action

In many cases, the chirping sound may be a minor issue that resolves on its own. However, there are certain instances when the sound indicates a problem that requires attention:

If the chirping persists for more than a day or two, it’s a sign there may be an underlying hardware or software issue. Persistent chirping should not be ignored.

Chirping that occurs every time you make a call or use a phone feature indicates a consistent malfunction. This requires troubleshooting the device.

Loud chirping that hurts your ears, especially when using headphones, is not normal and could damage hearing. Urgently address the problem.

Chirping accompanied by other issues like freezing, crashes, overheating or battery drain means a larger problem is likely occurring. Prompt troubleshooting is advised.

In summary, occasional minor chirping may not require action. But recurring chirping, especially if loud, consistent or paired with other problems, means investigating and repairing the phone is needed.
