iOS 15.4 new features, no interface iPhone is coming

With the advancement of science and technology, the most intuitive feeling of users is that the smartphone in their hands seems to have been doing "subtraction".

Cutting out unnecessary designs and making smartphones as a whole lighter, smaller, and more powerful at the same time is basically the main development trend in the technology industry.

At present, it is widely believed that the complete use of interfaceless design will be the next form of smart phones.

If you want to completely cut off the charging interface and completely adopt the interfaceless design, you must first solve a series of technical problems.

Recently, with the official update of iOS 15.4, a new feature that Apple has given to the iPhone seems to have given us a breakthrough in wireless technology.

According to Apple's official technical support documents, after updating the iPhone to the official version of iOS 15.4 and the Apple Watch to the official version of watchOS 8.5, we can restore the system for the Apple Watch through the iPhone.

When the Apple Watch needs to be updated or restored, the user simply places the Apple Watch on the charger, double-clicks the Apple Watch's side button, and follows the steps displayed on the iPhone.

In addition, when a red exclamation point appears on the screen of your Apple Watch, you can also press the side button twice and follow the steps above.

Friends who have used Apple Watch must know that if apple watch has a system failure problem that needs to be repaired, it is generally necessary to go to the retail store to seek the help of official technical personnel.

And now, after upgrading the latest system, we can completely solve it ourselves.

The introduction of this feature also seems to show us the tip of Apple's iceberg in the field of wireless technology.

If this technology can be further improved, it will basically solve the firmware repair problem of interfaceless devices.

In fact, as early as 2020, developers found a new feature called OS Recovery in the system firmware code of iOS 13.4.

Like network recovery on Mac computers, the OS Recovery feature allows users to wirelessly restore the device's firmware without having to connect to a computer.

We have reason to believe that this fix for the Apple Watch wireless firmware may also be a new feature developed based on this technology.

If you want to completely eliminate the charging interface and completely wirelessize the iPhone, you must solve the problem of wireless charging and data transmission.

In terms of wireless charging, Apple began to lay out a long time ago, and launched the MagSafe wireless charger in 2020.

Although Apple's current wireless charging technology is not satisfactory in terms of charging speed, it cannot completely replace the traditional charging method, but I believe that with the advancement of this technology, it is only a matter of time to replace traditional cable charging.

In addition, Apple has also enabled MFM certification based on wireless technology early, and its ambitions in the field of wireless technology are clear.

In terms of data transmission, there are also many changes.

In addition to the Apple Watch firmware repair function mentioned above, looking at our work and life today, we may be able to find that when there is a need for data transmission between devices, the data cable seems to be no longer the first choice.

Whether it is the airdrop function that comes with iPhone, iPad and Mac, or the web version of the file transfer function that has just been launched on WeChat, it basically meets the needs of users for data transmission.

Although these functions are limited by network speed and Bluetooth transmission speed, I believe that with the further upgrading of related technologies, it will bring more convenience to our work and life.

However, it will all take time.

There is speculation that Apple should use the lightning interface for transition in the next few years.

In the next step, Apple will most likely cut off the traditional charging interface, so that the iPhone completely gets rid of the shackles of the cable and redefines the next form of the smartphone.

Let's wait and see.
