A few years ago, Apple canceled the headphone jack for iPhone and replaced it with AirPods.
Let’s continue to talk about Apple’s “holeless” design. While the physical power and volume buttons will be cancelled, this is really not an area worthy of attention. This is because their technology is mature.
Meizu Zero was released in 2019 and is the world's first mobile phone without physical buttons, speaker sockets, SIM card slots or USB ports. This smartphone uses an eSIM card.
is more interested in the field of charging than technology. What does Apple plan to do with this charging port?
In the iPhone 12 series, Apple introduced Magsafe magnetic wireless charging technology. The company added a circle of magnets to wireless charging. It has changed the new wireless charging method for iPhone products, which provides an option for iPhone charging.
However, from the current leaked news, the iPhone 15 series will launch the Type-C unified interface under the pressure of the EU's unified interface.
If Apple may directly jump to the Type-C interface to avoid restrictions, can the MagSafe charging function handle charging of the iPhone 15 series separately?
While MagSafe charging is a good choice, there are concerns if it is ready to be the only charging option for phones like the iPhone 15 series.
MagSafe charger has its advantages and disadvantages. Let's take a look at the advantages and disadvantages of this charger:
MagSafe charger Advantages:
First of all, the wireless magnetic absorption method can make the phone more accurate when charging wirelessly. It avoids the problem of poor arrangement of charging coils affecting charging efficiency.
In addition, the use of magnetic suction can bring a wired charging experience to wireless charging. Of course, this logic is somewhat redundant. However, this feature has made great progress.
MagSafe Charger Disadvantages: Users of the
iPhone 12 series have personally experienced this charging "turtle speed" problem.
The wireless charging of this device is only 15W, and it needs to be "recharged all the time" to fully charge, but the situation is even worse. When the iPhone becomes hot during charging, the charging power drops to 7.5W~5W.
At this speed, the iPhone may even be powered off before it can be powered on. Worse, the heating frequency is quite frequent. If you use your phone while charging, your battery will drop rapidly.
Although there are many problems with Magsafe, Apple is likely to cancel the charging interface in the next few years. Let's continue to discuss why the iPhone 15 must remove the Lightning interface?
There are several points that make Apple consider changing the charging interface of the iPhone 15. As mentioned earlier, Apple cannot use its regular Lightning ports at least in Europe.
So Apple is looking for alternatives. Let's take a look at some of these points:

Friends who follow SevenTech will know that it has been reported that the European Parliament passed a bill in early October this year requiring all phones, tablets, cameras and other portable devices in Europe to use the USB Type-C interface from the fall of 2024.
The EU also requires further use of wireless charging technology by the end of 2026.
Subsequently, Apple's senior vice president of global marketing Greg Joswiak said that Apple will "must comply" with the EU's regulations on the unified charging interface for electronic devices.
From these perspectives, it is obvious that Apple will cancel the Lightning interface in the future. But it is still possible that the company will temporarily switch to the Type-C interface. After transitioning to a first-stage product, the iPhone will realize a "hole-free" design.

MagSafe has a "hidden" skill, which actually has a certain data transmission function. When the user connects the Mac to Magsafe and upgrades the firmware version to 1.74, the transfer rate option after connecting to the Mac can be seen as 12Mb/s.
This proves that Magsafe has a small amount of data transmission, capabilities and firmware update functions.The transmission rate of the Apple Watch's magnetic charger on Mac is exactly the same as that of Magsafe, both at 12Mb/s (Type-C interface version).
However, the charging function of Magsafe itself causes it to generate a lot of heat. It is difficult to maintain long-term data transmission capabilities.

For Apple, the biggest function of Lightning charging is to sell MFi certified chips, each costs 3 US dollars, that is, Apple authorized charging cable manufacturers need to purchase the corresponding MFi certified chips to adapt to charge iPhone, iPad and other products .
According to the British Daily Mail, Apple can achieve US$5 billion in revenue every year by selling Lightning interface charging cables and MFi certification. This even exceeds the annual revenue and profits of some mobile phone brands.
MagSafe is also certified, and its official name is MFM certification. Apple "recognizes" these third-party accessories brands by charging royalties for third-party accessories.

iPhone's Lightning interface transmission rate remains at the USB 2.0 standard. Therefore, iPhone data transmission has encountered a bottleneck.
For example, in iPhone 14 Pro, photos using ProRAW format (48MP) are about 75MB. Currently, the speed limit of iPhones using Lightning interface is only 480Mbps, and after conversion it is almost 60MB/s.
In actual testing, the speed of Mac using Type-C to Lightning data cable to transmit data to iPhone 14ProMax is only 33MB/s.

AirDrop is the fastest way to transfer iPhone phones at present. According to Apple's official technical documents, AirDrop communicates data through a point-to-point network.
First, it will connect over Bluetooth, pair each other, and then use WiFi for physical layer transmission. It does not require a network connection. For transmission effects, the closer the AirDrop airdrop transmission distance, the faster the speed. If the distance is too far, the connection cannot be made.
Even if the iPhone 15 uses "holeless", it won't be the first phone to do so.
A few years ago, domestic brands launched several "holeless" devices. Vivo and Meizu have launched holeless phones. Vivo has launched a total of two hole-free concept phones, Vivo APEX 2019 and APEX 2020.
Vivo APEX 2019 is Vivo's first hole-free concept mobile phone. There is also Meizu's concept mobile phone, Meizu ZERO, which directly abandons the SIM card compared to Vivo. It uses eSIM virtual card and adds screen sound technology. In terms of
charging, Meizu ZERO also uses wireless charging, but the power is only 18W.
