However, a common concern among iPhone users is whether magnetic phone holders can damage their devices. 

But with conflicting opinions and online information, it can be challenging to determine the truth. 

And there is where we come in! We will provide all the information you need on this topic and answer the question; do magnetic phone holders damage iPhones? 

Magnetic phone holders typically use weak magnets, and their magnetic fields are not strong enough to cause damage to any of the components in an iPhone or other smartphones. 

Therefore, using a magnetic phone holder should not pose any risk of harm to your device.

How Do Magnetic Phone Holders Work?

Magnetic phone holders operate on the principle of magnetism to securely hold smartphones in place. They consist of a mount with a powerful magnet, typically attached to surfaces like car dashboards or walls. 

A thin metal plate, usually made of ferromagnetic material such as iron or steel, is fixed on the back of the phone or between the phone and its case.

When the metal plate on the phone comes close to the magnet in the mount, it attracts the metal plate, creating a firm magnetic connection between the phone and the mount. 

This magnetic attraction ensures the phone remains securely in place, even when subjected to movement or vibrations.

How Do Magnets Affect Electronic Devices

Magnets can significantly impact electronic devices, and it is essential to understand how they can affect various components. 

However, it’s worth noting that most modern electronics, such as smartphones, tablets, and laptops, are designed to resist the average magnetic fields we encounter daily.

Compass and sensor interference

Many electronic devices, including smartphones and navigation systems, rely on built-in sensors like magnetometers to detect magnetic fields and determine orientation. 

Placing a strong magnet near these devices can interfere with the accurate functioning of the sensors, leading to incorrect compass readings, navigation errors, or sensor malfunctions.

Induced current 

A magnetic field moving across a conductor creates an electric current. And this can occur in electronic devices that contain conductive materials such as copper or aluminum. 

If a strong magnet comes close to these devices, it can induce a current that can cause damage to the device’s circuitry or components.

Data Loss or Corruption

Magnets, such as hard disk drives (HDDs) and magnetic tapes, can adversely affect storage media. These storage devices use magnetism to read and write data. 

When exposed to a strong magnetic field, the magnetic alignment of the data on the storage medium can be disrupted, leading to data loss or corruption. 

Image disruption on CRT

Do you still remember the Cathode Ray Tube (CRT) monitors? And how about how they work? They use electron beams controlled by magnetic fields to create images. 

If a magnet that is strong enough is too close to a CRT screen, it can cause image distortion, color aberrations, or even permanent damage to the display.

Magnetic Interference

Electronic components, such as transistors and integrated circuits, are designed to operate within specific voltage and current ranges. 

When exposed to a strong magnetic field, these components may experience fluctuations in voltage or current, leading to incorrect operation, malfunctions, or even permanent damage.

Alternatives To Magnetic Phone Holders

While driving, we often use our phones for navigation because holding them while driving can be dangerous. 

That’s where phone holders come in handy. Magnetic phone holders are popular but may only be the best option in some cases. Therefore, it is essential to have alternatives to magnetic phone holders. 

  • Adjustable clamps – These clamps are adjustable to fit various phone sizes and shapes, and they often come with different mounting options, such as air vent clips or dash mounts. While quick and easy to use than magnetic holders, adjustable clamps are a reliable option for those who want a more secure hold on their phone while driving.
  • Suction mechanism – Some phone holders use a suction mechanism to attach the phone to the mount. These holders typically have a suction cup that adheres to the back of the phone. The suction cup creates a seal securely holding the phone in place. The suction mechanism offers a firm grip and allows for easy attachment and removal of the phone
  • Adhesive phone holder – These holders attach to the back or phone case using a strong adhesive material. While these holders may not be as easily adjustable as some other options, they offer a simple and effective way to keep the phone securely in place while driving.
  • Locking mechanism – It uses a locking mechanism to hold the phone securely. The locking mechanism provides a firm grip, preventing accidental slips or falls during bumpy rides.

Battery Health and Magnetic Phone Holders, How Does It Affect Your Battery Life?

There are concerns about how magnetic holders can impact the battery health of smartphones. The magnets in magnetic phone holders are typically positioned near the back of the phone, close to the battery. 

Lithium-ion batteries, commonly used in modern smartphones, are highly sensitive to magnetic fields. 

Although the magnets in phone holders may not have strong enough magnetic fields to directly harm the battery, they can impact its performance and longevity over time. Placing magnets near a smartphone’s battery can affect the calibration of the battery’s sensors. 

Accurate sensor readings are crucial for determining the battery’s charge level and optimizing the charging process. 

However, if any external factors interfere with these readings, such as magnets, it can result in inaccurate battery level indications. 

This can lead to overcharging or undercharging of the battery, ultimately affecting the smartphone’s overall performance.

Additionally, the heat generated by the magnets can affect the battery’s performance and longevity. Excessive heat is known to degrade lithium-ion batteries faster. 

The magnets can increase heat generation and potentially accelerate battery degradation when the phone is attached to a magnetic holder, especially during charging or extensive usage.

How Can You Avoid Magnetic Interference?

You can take several steps to protect your iPhone from potential magnetic interference. Firstly, keeping your device away from strong magnetic fields is crucial. 

Avoid placing it near powerful magnets or electromagnetic devices, as they can generate magnetic fields that may interfere with your iPhone’s performance. You should also be cautious about using magnetic accessories, such as holders or cases. 

These accessories contain magnets that could disrupt the device’s functionality, including the camera, compass, or internal sensors. Opt for non-magnetic alternatives to securely mount or protect your iPhone. 

If you work in an environment with strong magnetic fields, consider using specialized cases or covers to shield your iPhone from magnetic interference. Or just go with your iPhone in such an environment.

Can Magnetic Accessories Interfere With Your iPhone Camera?

A powerful magnetic field can disrupt the functioning of OIS and closed-loop AF lens-position sensors sensitive to magnetic fields.

Whenever a magnet is placed near these sensors, they become susceptible to interference or temporary deactivation resulting in a reduction in the accuracy of the sensors and limitations in the range of movement of the camera lenses. 

As a result, the camera’s stabilization functions will not benefit from OIS and closed-loop AF. However, the camera can still take pictures using other stabilization methods. 

To optimize the performance of your iPhone camera, refrain from using accessories that utilize magnets or magnetic metals near the rear cameras.

Is It Possible To Wirelessly Charge Your Phone With Its Magnetic Case Still On?

Wireless charging uses magnetic fields to transfer electricity wirelessly. However, this technology may face some challenges regarding interference from magnets. 

Magnets can disrupt the wireless charging process, making it difficult for the two to function seamlessly. 

As a result, Apple recommends avoiding magnetic mounts, magnetic cases, and any other objects that may interfere with the charging process. 

While your device may still charge with these objects in place, it may not operate optimally due to magnetic interference.


Do magnetic phone holders damage iPhone? The use of magnetic phone holders does not necessarily result in damage to an iPhone. 

Most magnetic phone holders have weak magnets that won’t harm the iPhone. 

However, if the magnet is strong, overtime exposure can lead to the abovementioned problems. It is, therefore, important to exercise some caution when using and choosing these holders.
