Since its debut, the distinctive design of the iPhone has captivated millions around the world, but basically from the first models with the metal chassis there is one common element that we see: the side stripes of the case.
In this post, we will explore in detail the technical functions of the iPhone's side stripes, we will explain what they are and, above all, why it is important that they are there in good condition.
What are the side stripes on iPhones?
The "side stripes" on iPhones, present on all models since the iPhone 4S, are actually sections of the device's structure that They are specifically designed to house the internal antennas, which are built with materials that allow efficient transmission and reception of wireless signals, such as mobile networks, Wi-Fi and Bluetooth.
But be careful, just because they are there does not mean that they are the only antennas on the phone, since there are different types of antennas inside the iPhone, each one designed to operate in a certain frequency band and with different performance characteristics.
The specific design and placement of these antennas is critical to maximizing wireless signal efficiency and minimizing electromagnetic interference between the antennas and other device components.
For all this, the side stripes of the iPhone are carefully designed, integrating into the metal casing of the device while maintaining an aesthetic appearance consistent with the general design of the product, being made of materials that allow the passage of wireless signals without significant obstacles but durable enough so that they are not something flimsy and will wear out over time
Types of antennas on an iPhone
Specifically, inside an iPhone we have different types of antennas, as we have said before:
- Mobile network antennas: These antennas are designed to receive and transmit signals from mobile networks, allowing Internet connectivity and making calls through these networks.
- Wi-Fi and Bluetooth antennas: These antennas facilitate the connection to Wi-Fi networks and nearby Bluetooth devices, enabling functions such as data transfer, device synchronization, and connection to accessories such as wireless headphones. They usually go together since the component used for both technologies is the same, just like in computers.
- Satellite positioning antennas (GPS): Some iPhone models also include antennas designed to receive signals from satellite positioning systems, such as GPS, allowing navigation and precise location of the device.
So while they may seem like just a silly design quirk, these iPhone side stripes are more important than they seem, playing a critical role in your phone's wireless functionality.
Does it affect the functionality of the “side stripes” on the iPhone if I use cases?
Metal cases are not very advisable on an iPhone
I have been asked this question more than once in my time in Technical Service, and the answer is a big DEPENDS.
It is undeniable that Using cases to protect an iPhone may affect the effectiveness of the internal antennas in certain circumstances, although in general, most cases should not significantly interfere with the device's wireless connectivity. There is a percentage of loss of a phone with and without a case, but it is not considerable enough to be something significant.
Specifically, with the issue of covers there are certain things that must be taken into account:
Cover material
Some case materials, such as metal or thick materials that block signals, can interfere with the transmission and reception of wireless signals, so whenever possible use cases with materials such as silicone, TPU or other flexible plastic materials. They tend to have less impact on the wireless signal, in addition to being a lot of damping. better against bumps and falls.
Personally, I would rule out any metal case due to its low shock absorption capacity, in addition to the fact that materials such as steel, aluminum or alloys are conductive materials, which can create electromagnetic interference that negatively affects the coverage on an iPhone.
cover design
Some covers They can partially or completely cover the areas where the iPhone antennas are located or what is worse, they may have materials that insulate right in the part where the side antennas go.
However, many cases are designed with specific cutouts to allow the antennas to operate unobstructed.
Can the side stripes on the iPhone be damaged?
A damaged “side scratch” on an iPhone 15 due to a manufacturing defect
This is another question that I have been asked in the past and that we think is important for you to know. The side stripes of the iPhone can be damaged, causing a breakdown in the terminal, which also has a very drastic solution, since it involves directly changing the entire phone case.
Specifically, the failures that most affect coverage antennas, based on my experience, are the following:
Physical damage
The Bumps or falls are the main reason why the side stripes of the iPhone can be damaged, compromising the integrity of the antennas that are integrated into them and directly leading us to have a coverage problem with the mobile phone.
Use wear
Over time, the side stripes on the iPhone could experience wear and tear due to regular use of the device, passing through scratches, dents or due to accidental misuse such as washing the phone with abrasive materials, or even using the phone with hands dirty with grease or sun cream. So, if you are going to use your cell phone, it is better with clean and dry hands.
All of this in the long run and with the passage of time can wear out the antenna material, causing the casing to be replaced.
Design or manufacturing problems
In some cases, and although it is not common, There are shipments of iPhone affected by manufacturing problems with the side stripes of the iPhone, but if you detect it at the same time, Apple's own warranty covers it.
If some time has passed and you suspect that what is behind it is a manufacturing defect, it doesn't hurt to go to an Apple Store or contact its Support, since perhaps there is an internal protocol that even if your phone is out of warranty, Apple must replace the case because it is part of a bad shipment, at no cost to you.
