Wireless Charging For Smartphones: How Does It Work?
Wireless charger works by using an electromagnetic wave to transmit power. The waves are picked up by the receiver coil embedded in your phone’s back, which transforms them into electricity.
The electricity generated is used to charge your smartphone. You’ve probably already determined whether or not your smartphone is equipped with wireless charging capability.
The only thing you will notice when you place your smartphone on a wireless charging pad is the change in your battery icon from the standard mode to one with a bolt at the center. This signaling that your phone is being charged is active.
Wireless charger can also be referred to by the names Qi charging, or Qi technology. Qi was first introduced in 2008. The technology is still relatively new. Qi can use both inductive and resonant charging. Inductive charging requires that devices be close to one another for the latter to work.

Pros And Cons Of Wireless Charging
Pros
Wireless is not precisely wireless. This device is not able to do this. While a cord allows you to move about the length of the cord, wireless charging requires that your phone remains on the wireless charging pads to charge continuously.
Your phone is not available to you. Refer to the above. To continue charging, the phone must remain on the pad.
It takes longer for your phone to charge. Qi charging’s efficiency is lower than that of cable charging. Wireless charger takes longer and uses more power. It takes wireless charging 30-80% longer than cable charging to charge your devices entirely.
Pay more attention to your phone. The biggest problem that people often overlook is the importance of charging their phones. Because if you grab your phone to use it quickly while it is charging, you need to be more careful when you place it down.
People have become accustomed to picking up their phones and then putting them down. It’s not an issue if you have a cord attached.
It won’t charge if your phone isn’t placed correctly on the pad or you place it back down without thinking. This is a significant problem with wireless charger, as I can attest.
Wireless charger pads are more expensive than cables chargers. These pads are a relatively new technology and can be more expensive than cable chargers.
Cons
There are fewer cords to worry about. This is a simple one. Wireless technology means you don’t have to take your USB-C charger everywhere you go. All you need is one cable to connect to the charging mat.
- Universal compatibility: Qi-certified charging is the standard.
- Securer connections: The charging takes place in an enclosed environment without using cords, and there’s no risk of corrosion. Also, there’s less chance of electrical faults. This is a huge plus since many companies sell janky charging cables. Do you need a lightning line certified? This one is permitted.
- More durable: The smartphone sockets are also more durable because they don’t need to be plugged and unplugged as often. You can charge your phone wirelessly or with cables. This will also reduce the wear on your cables.
- Won’t overheat your devices: The wireless charger automatically turns off when your smartphone has fully charged. This safer charging method uses less energy and doesn’t heat the battery.

Are Wireless Chargers Safe? Best Things To Know 2022
Does Wireless Charging Work With A Case
Let’s first look at the wireless charger devices.
The majority of significant smartphone manufacturers use Qi-standard wireless charging technology. Each brand has its chargers with slightly different wattages. The technology behind the chargers is the same. It transfers electricity to your phone using electromagnetic induction.
Even if you aren’t a physicist, engineer, or entrepreneur, you might have played with magnets when you were a child. You may have learned a few things about magnets from your parents.
Other magnets, metals, and any other material that is too thick to allow the magnetic field through are all examples. The same principle applies to smartphone cases.
These are the major culprits.
- Thick Cases – Thicker cases and heavier phone cases can interfere with wireless charging. The wireless charging capabilities of your case is influenced by the thickness of your case. As a result, a thick case can impede the electro-magnetic field, preventing wireless charging. Very thick cases might also cause the phone to overheat when charging, potentially damaging the battery as well as the charger and phone. They can block the electromagnetic field and can even cause damage to your phone, charger, or case.
- Metal Cases – Metal cases can interfere with your wireless charging pad’s electromagnetic signal. This is why Apple switched from aluminum shell backs to glass backs for iPhones when wireless charger became the norm.
- Wallet cases – It’s not the case that matters, but what it contains. Magnetic fields can damage things like RFID chips and credit cards.
- Battery Cases – These are power banks that attach to your phone and can also cause problems with charging. However, many manufacturers such as Samsung and Apple have created battery cases that are compatible with charging.
If you are having problems with slow or nonexistent charging, and your phone case falls into one of these categories, take it off to test if that helps.
Another thing to note: Not all wireless chargers work equally well. Some charger products will be slower or weaker than others no matter what phone case you use.
Phone Cases That Work With Wireless Charging
Do not let this list scare you. As we mentioned earlier, charging shouldn’t be a problem for most phone cases.
These phone cases can be made of plastic, rubber, leather, and synthetic materials, provided they are not too thick. Despite this, they all have one thing in common: They aren’t great for the environment.
They are harmful from production to disposal and leach toxic chemicals into the environment.
What’s The Solution?
Use A Biodegradable Case
A biodegradable case for your phone made from sustainable materials is an option. Pela goes further and makes our Samsung and iPhone cases biodegradable. This means that they can be recycled more quickly and more efficiently.
You don’t need to worry about your old case getting lost next time you buy a new phone or upgrade it. The best part? Our cases don’t slow down wireless charging and are quick and easy to remove and put on again as needed.
If you have a case, ensure that you use a screen protector. Your phone’s screen, after all, is its most important and vulnerable area. Liquid screen protectors are flexible enough to fit most phones, won’t impede charging, and don’t add bulk to your pockets or purse.
It would help if you used a first-party or similar wireless charger for maximum compatibility. This is a great idea regardless of the phone case.
Wirelessly Charge Your Smartphone With The Rokform Case
There are several ways to allow charging while your Rokform case is still on.
Option 1: Disable the magnet embedded in your phone. The magnet will not work with magnet technology. However, your phone can’t charge while it’s on its charging station.
Option 2: You can remove the magnet from your case and replace it with a Magnetic RokLock plug. Customers will be able to wirelessly charge their phones by removing the Neodymium magnet located in the middle of their phone and replacing it with the magnetic magnet inside the Magnetic RokLock Plug.
Customers can now charge their phones wirelessly without removing the Neodymium magnet located in the middle of the phone.
Option 3: Charge wirelessly with your RokLock Wireless Charger while your phone’s mounted. These products allow you to charge your phone wirelessly even while it is mounted.
Mount your RokLock Wireless Charger on your car mount, then attach your Rokform case. Because your RokLock Wireless Charger is securely mounted to your car mount, you won’t need to worry about any drawbacks mentioned above.

FAQs
What Thickness Is Impenetrable To Wireless Charging For Your Smartphone Case?
Many wireless charger manufacturers recommend that a phone case not be thicker than 3 to 5 mm. This is 0.15 inches to 0.19 inches. A quarter of an inch or 0.25 inches equals 6.35mm. This is quite thick in the Cell Phone Case World.
Wikipedia has some (mm) millimeter averages:
- 1.0 mm – Diameter of a pinhead
- 1.5mm – Average Flea Length
- 5 mm – Average Red Ant Length
Is It Necessary To Take My Smartphone Out Of Its Case In Order To Use A Wireless Charging Pad?
Some smartphones may require that the user remove the phone from its case to charge wirelessly. The lighter cases will pick up signals almost all the time, while thicker patients may not be able to do so. Imagine that your smartphone was placed inside a sealed tin or wrapped in layers of masking tape.
Yes, the phone would struggle to receive a signal. However, it is essential to note that a wireless charger can charge a phone without the need for it to touch it.
These items are similar to the older iPod docks, but they don’t work similarly. Wireless chargers are not as bulky as older charging docks.
However, they don’t require you to take your phone out of any case. Many people report that wireless chargers can be used without removing their phones from cases. It works regardless of whether the case is included or not.
It’s difficult to answer this question with a clear yes or no. It may depend on the case, the phone, and the wireless charger. Each of these variables can make a difference in the final result.
You shouldn’t remove smartphones from their cases to enjoy the benefits of something they don’t need, but rather, they should be kept close by.
How Do Cases Affect Compatibility?
As discussed, the case can be harmful to use with a wireless charging stand or pad. However, this is not a rule. Smartphones are meant to be kept in protective cases. The wireless charging pad is designed to be convenient and easy to use.
All cases are different, so the average case shouldn’t be a problem. Some phone cases can be very bulky, while others are unnecessary. They could even be thick enough to create a barrier between wireless charging currents and the smartphone itself.
Which Smartphone Cases Are Better For Wireless Charging?
It is not recommended to have a charge that is too thick. The charge’s quality will be affected by the thickness. In our experience, it either works, or it doesn’t work with a case. The strength of the wireless charger will determine if the phone can charge on a station or wireless charging pad.
The Smartphone can use the technology without the need for a case. As stated before, it won’t charge quicker or keep its charge longer.
There is evidence to show that certain materials are better conductors than other materials. A metal case may conduct electricity more efficiently than a rubber case, but this is only a matter of compatibility based on its thickness.
It is more likely that a phone with a metal case will not benefit from wireless charging technology than evidence.
To make wireless charging technology more accessible, smartphone manufacturers make phones without metal sheets on their backs. This is excellent news for anyone who has a case that they like. We recommend avoiding metal cases based on these facts.
Why Might a Case Make Wireless Charging Difficult?
Wireless charging works by using electromagnetic induction to transfer power from the charging pad to your phone’s battery. A physical connection between the phone and the charger is required for this.
The case can prevent electricity from being transferred if it is too thick or constructed of the improper material.
Conclusion
Wireless charging is an excellent technology, and I am glad that Apple has adopted it in their latest iPhones. Everything should go smoothly as long as you do your research when purchasing your charger and case. We hope you found this article useful and if you did, please share it with your friends!
