9 min readMar 8, 2024

Magnets have long existed in the smartphone and accessory industry. But magnetic accessories weren’t much seen back then. After Apple introduced the iPhone 12 with built-in magnets in 2022, magnetic phone accessories quickly gained popularity. But the question remains: Are magnets bad for phones?

How to Safely Use Magnets with Phones

With such importance placed on magnets in phones and daily accessories, it’s crucial to know how to protect them from potential harm.

Essential Dos and Don’ts for Using Magnets with Phones

Let’s start with the dos. Magnets can be beneficial when used with phones in the right way.

Magnetic phone cases are usually safe, as are magnetic phone mounts and wallets. These magnets are generally designed to have minimal interference with the device’s functionality.

However, it’s important to be aware of the don’ts when it comes to using magnets with phones. Don’t place strong magnets near your phone. Magnets can interfere with the operation of the phone’s internal components and potentially cause irreparable damage. So, steer clear of placing your phone directly on magnetic surfaces or attaching powerful magnets directly to the phone itself.

Choosing Compatible & Certified Magnetic Accessories

Compatible and certified magnetic accessories undergo rigorous testing to ensure they do not interfere with the phone’s functionality. These accessories are specifically designed with shielding materials or accurate magnet placement to protect the phone from potential damage and malfunctions.

To determine if a magnetic accessory is compatible and certified, look for reputable brands that adhere to industry standards and regulations. Check for certifications such as the MFi (Made for iPhone) certification or Qi standard. Reading product reviews and seeking recommendations from trusted sources can also help you make an informed decision.

Magnetic phone cases and accessories use magnets to stick your phone in a place for a convenient hands-free experience or stable wireless charging. That said, it doesn’t necessarily mean the stronger the magnetic force is, the better.

Just ensure your phone won’t fall off when you use those magnetic accessories. For instance, using a magnetic phone mount in your car can provide a hands-free solution for navigation and answering calls. Your car mount should be strong enough to keep your device in place even on bumpy roads. Over-strong magnets will make pulling your phone from the mount difficult and may even cause interference with the device’s performance.

Proper Mounting Techniques: Placement & Alignment for Optimal Security

When it comes to mounting your phone, first consider placement.

Choose a location that offers easy access without obstructing your view in a car. Place the mount on the dashboard or air vents for easy reach and minimal distractions while driving. If you want to install the mount on the windshield, make sure it’s not against the local rules. Check out more tips on selecting the best car mount here.

Also, ensure your phone is aligned properly. The biggest upside of magnetic mounts is that they auto align with your phone. When you move your phone over the mount, it automatically clicks into place. Sometimes, you may need to move it around a bit to hear the “click”. Additionally, some car mounts can be adjustable, allowing you to position your phone at the most comfortable angle.

When Did We Start Using Magnetic Phone Cases?

About a decade ago, magnetic phone cases were not even a thing. Only a few manufacturers used magnets on phone cases. PITAKA was among one of them.

A Brief History of Magnetic Phone Cases

In 2015, we found that if we wanted to attach a mobile phone to a magnetic car phone holder, we had to use adhesive or magnetic metal plates. Applying a metal plate made the case thick and not at all appealing. So we developed a phone case that can be directly attached to the magnetic car mount. Soon, the MagEZ Case for phones, one of the first aramid fiber phone cases with magnets, was born.

We embedded crescent-shaped magnets in cases for iPhone and Samsung phones, such as iPhone X and Samsung Galaxy S7 series. Meanwhile, we also developed a series of magnetic phone accessories to provide a seamless phone experience. We had magnetic phone holders to use in the car or at the desk, which works effortlessly with our magnetic phone cases and can provide Qi wireless charging.

Comparing Early vs. Modern Magnetic Phone Cases

Over time, sales grew. A few more manufacturers entered the ring; meanwhile, we upgraded the design to make our magnetic phone cases more beautiful and useful. Magnetic phone cases grew popular, albeit slowly.

In 2020, Apple introduced MagSafe, a system that uses magnets in the iPhone and they also released wallets and chargers with the same array of magnets. Since then, many people have realized how convenient magnetic phone cases and accessories can be; thus, the market has begun to thrive rapidly. And we upgraded the magnets in our phone cases, from crescent-shaped to array magnets.

Nowadays, magnetic phone cases are made from all kinds of materials,

just like non-magnetic phone cases do. They can also come with kicks or wallets to offer more functionalities.

Are Magnetic Phone Cases Bad for Phones?

Magnetic phone cases are safe for phones. Here are the detailed explanations.

Addressing Common Concerns about Magnet & Phone Safety

The severity of the impact largely depends on the strength and proximity of the magnet to the phone. Ordinary household magnets typically don’t pose a significant threat. Smartphones today are equipped with built-in magnetic sensors. These sensors are designed to detect and respond to magnetic fields, enabling features like compasses or magnetic phone covers. Manufacturers take special precautions to ensure these magnetic sensors are not affected by everyday magnets, so ordinary use should not generally cause harm.

Understanding the Potential Risks: Signal Interference, Compass Disruption

It’s essential to recognize that magnets can potentially interfere with the proper functioning of mobile phones. The electronic components within our phones, such as the speakers, microphones, and sensors, can experience disruption when exposed to a strong magnetic field. This interference can result in distorted audio, inconsistent touch response, or even irreversible damage to the device.

Choosing Safe Magnetic Cases: Magnet Strength, Placement & Material Considerations

When it comes to choosing a safe magnetic case for your phone, there are several important considerations to keep in mind. One of the primary concerns is the strength of the magnets used in the case. While magnets can be a convenient way to mount your phone or attach accessories, they can potentially interfere with the internal components of your device. Therefore, it is crucial to opt for magnetic cases with proper magnetic strength, ensuring they don’t cause any harm to your phone. It’s not that the strongest is the best.

Another factor to consider is the placement of the magnets within the case. It is vital to choose a magnetic case that strategically positions the magnets away from sensitive areas of your phone, such as the battery or the circuitry. This will help prevent any potential interference or damage to your device.

Moreover, the material used in the construction of the magnetic case is equally important. Opt for cases made from non-conductive materials to further mitigate any potential risks. Common materials like silicone or TPU are non-conductive. In recent years, carbon fiber phone cases have attracted many people’s attention. But note that carbon fiber is conductive, meaning it will affect the phone signal. Aramid fiber, on the other hand, is not conductive and is an ideal phone case material, given that it’s extremely lightweight yet durable like carbon fiber.

What Are The Best Materials For A Magnetic Phone Case?

Speaking of phone case materials, let’s dive into more details.

Common Magnetic Case Materials: Durability, Protection & Safety Aspects

Silicone magnetic cases are flexible and have shock-absorption capabilities. They provide a snug fit for your phone and offer decent protection against everyday bumps and drops. However, silicone cases are prone to attracting dust and lint, which can be a hassle to clean.

Plastic magnetic cases, on the other hand, often have a hard shell that offers more protection against scratches and abrasions. They are also more resistant to dust and lint compared to silicone cases. But they could look cheap.

Leather magnetic cases offer a sophisticated look and feel, protecting the phone against scratches and everyday wear and will develop patina over time, adding a unique touch to your style. They are usually heavier than silicone or plastic cases.

Aramid fiber magnetic phone cases are lightweight yet durable. It’s a high-tech material often used in aerospace and military applications. They are resistant to corrosion, scratches, heat, and water, making it easy to last for years.

Aramid Fiber vs. Traditional Materials

Aramid fiber could be the best phone case material. It’s lighter than all other common materials, yet it’s much more durable. And it’s the most chemically stable of all.

A decade ago, PITAKA started to use this high-tech material to make phone cases. After about 40 processes, our aramid fiber phone cases boast a velvet-like texture but with excellent grip.

Are Magnetic Car Phone Holders Safe For Your Phone?

PITAKA’s magnetic car phone holders do not cause problems to phones. They provide a secure and accessible way to mount your smartphone while driving.
