Why is My Phone Making a High-Pitched Noise?

When you hear a high-pitched noise on your phone, it’s natural to be worried. But don’t worry; you should be able to pinpoint the source of the high-pitched noise coming from your phone, so admit it. You’re not the only one who’s having difficulty with this. Stop asking yourself, “Why is my phone making a high-pitched noise?” and find a solution.

The phone making a high-pitched noise, indicates there are some issues that you simply can not ignore; however, before you jump to any conclusions, figure out what’s causing the noise and when it’s happening. When and how your phone makes noises are important factors to consider. It could be a loud noise or it could be making noises while charging or calling.

Electricity Issue

Before you blame your charger, check your socket or charging port because electrical outlets can sometimes generate buzzing or other high-pitched noises. Whether you think your charging port is producing noise and the charger makes noise when plugged in then try to change the wall outlet or socket and see if your phone is still making high-pitched sounds or not. 

If not then stop being worried. Because your phone is up to date it is just an electricity issue.

Network Difficulty

A phone may occasionally make a high-pitched sound, and it is a result of network failure. The main cause of these network problems is the mobile company’s poor cellular service. This type of difficulty is also determined by the location of your phone.

To avoid this type of issue, ask someone else on the same network to clarify the noise issue on your phone, or change your location to compare the network problem.

Do Focus On The Magnetic Field

Every charger contains a magnetic steel sheet inside of it. Sometimes during charging, this steel sheet extends itself and creates a vibration. And because of the vibration, a high-pitched noise can be created. But don’t worry, because if you just give your charger a chance to cool down, everything will be fine. This type of problem is mainly seen on the iPhone. So, if your iPhone charger makes a noise when it’s plugged in, just give it a few tries.

Buggy Software

An Android phone is filled with a variety of software, and I bet you get notifications almost every day to update any of them. Some of those software updates may contain bugs, and those bugs can create a high-pitched noise. If these types of issues are raised, then do not be concerned because manufacturers usually resolve them as soon as possible. Installing third-party software for personal security, on the other hand, should be avoided.

Transformer Issue

Every phone has a transformer, but it may differ in size such as it can be a tiny one or it can be a high-frequency transformer. When the battery on your phone is about to die, the transformer can produce a variety of high-pitched sounds. However, once your phone becomes fully charged, this issue will be resolved.

In the same way, a portable charger can also make noise because a tiny transformer within the charger usually functions at a high frequency of power, which is more than 50 Hz. When your phone’s battery percentage is really low, the charger works extra hard and consumes more energy. Because of this, sometimes a high-pitched noise can be produced. 

Hardware Problem

It has become a normal occurrence that every android user’s phone falls down from their hand or from a higher distance at least once in their lifetime, but the issue is that because of this type of issue, the hardware of the phone can be damaged. 

Moreover, hardware is related to the microphone and speaker, so when someone tries to pick up a call, a high-pitched noise can be produced, or maybe you may notice your charger making a buzzing noise because the hardware system of your phone may get hampered. 

Defective Charger

It’s normal for a charger to be damaged after using it for a long time. If your charger becomes damaged, just throw it away. Because using a damaged charger can cause a buzzing noise, including electrocuting incidents.

Short Circuit Issue

A short circuit can happen when electricity flows through an unintended electric line. When your charger faces a short circuit, it may create a high-pitched sound. So if your charger is making a buzzing noise because of a short circuit, plug out your charger immediately. 

Charger With Fans

A few wireless chargers contain fans. Because of this, wireless chargers produce more heat than wired chargers. So, if your wireless charger makes a noise, do not overheat it so that the fan can settle down.

Tapped Phone

If you hear a continuous sound, it means there is a high possibility that your phone is being tapped. This sound is mostly heard during a phone call. After facing this type of problem, cut the call and just check the dialer of your phone to check what is actually happening.

Low-Quality Charger

To avoid high-pitched sounds, you should not use a low-quality or off-band charger. You should prefer the charger that has been given to your phone. A random charger takes time to adjust to your phone and creates noise. If you tested a random charge on your smartphone and the battery of your phone made noise while charging, then you should try the branded one.

Fast Charging Process

A fast charging mode can cause high-pitched noises because power and energy convert very quickly, and voltage also increases rapidly, causing a high force shift into the magnetic field, where a sound wave can be created. And when the sound waves reach a certain level, you may hear a high-pitched sound.

Outlet Issue

If your outlet makes a buzzing sound while charging, then it is not a good indication for you. Because of the high-pitched sound, a fire occurrence can happen because of the usage of an inappropriate outlet. To avoid this type of occurrence, stop using the defeated outlets.

Problematic Component 

The lossy component of a charger can produce a high-pitched sound. There are a few known components available on the market named diodes, capacitors, transformers, and rectifiers. So, if any of these components become loose while in use, simply stop using them to avoid the high-pitched sound.

Battery Issues 

Your phone can make a high-pitched noise sometimes because of the battery issue. In this case, you should replace the battery to solve this kind of problem. Because it is possible that you have been using your battery for so long that your phone battery becomes tired of giving you service.

Type of Other Phone Noises 

Mostly, the buzzing sound is the most common sound for everyone, but excluding the buzzing sound, there are a few more noises that you may hear from your smartphone. Such as: 

  • Screechy noise
  • Hissing noise
  • Buzzing noise
  • Siren noise

  • beeping noise
  • Static noise
  • Humming noise
