iOS 15.4 optimizes 5G, signal is fully restored

Nowadays, 5G technology is developing rapidly, and everyone is looking forward to the popularization of 5G technology, which will change our lives again.

At the same time, thanks to the huge demand for 5G mobile phones in the Chinese market, major mobile phone manufacturers have entered the market and jointly promoted the sales of 5G smartphones worldwide.

According to statistics from research firm Counterpoint Research, in January this year, 5G smartphones accounted for more than 50% of the global smartphone sales list for the first time.

In this data, Apple is the only one that dominates, accounting for 37% of the market share, making the iPhone the best-selling 5G smartphone in the world.

In addition, in the Top 10 smartphone sales ranking for 2021 provided by Counterpoint Research, the iPhone also firmly occupied the top five spots on the list.

Among them, iPhone 12, as the first iPhone to support 5G, has firmly secured the top spot on the 2021 smartphone sales list.

Therefore, users' demand for 5G iPhone is evident.

The iPhone 13 series released last year is even more eye-catching. Its outstanding performance has made it the new favorite of 5G iPhone users. It triggered a buying frenzy as soon as it was released.

Following this trend, the iPhone 13 series is still the favorite to win the smartphone sales list this year, and it is only a matter of time before it surpasses the iPhone 12.

According to the latest news, after the iPhone 13 is upgraded to the latest iOS 15.4 system, the Internet speed has also been greatly improved compared to before.

According to feedback from a netizen on the Communication People's Home Forum, after the iPhone 13 using a China Mobile SIM card updated to iOS 15.4, the 30M N28 frequency band was supported in the IPCC (operator profile).

The N28 frequency band, also known as the 700MHz frequency band, is China Radio and Television's 5G frequency band, with the advantages of low frequency and strong coverage.

Previously, China Radio and Television Corporation has opened and shared the 700MHz frequency band with China Mobile, which will also be one of the important frequency bands for domestic 5G communications in the future.

Friends who have an iPhone 13 and a China Mobile SIM card may want to experience it after updating to iOS 15.4.

In addition, the netizen said that the download speed and signal have been improved compared to before.

The signal problem has always been a problem that iPhone users complain about the most, and communication has never been Apple's strong point.

Previously, an iPhone user joked that he always thought that smartphones had no signal in elevators until he saw an Android user watching short videos in the elevator.

In fact, Apple has also been actively developing its own baseband chips, focusing on improving signal problems.

At present, there has been new progress in the research and development of Apple baseband chips.

According to the news sent by digital blogger @手机芯片达人, Apple's mmw millimeter wave radio frequency RF chip has been designed and the chip code is Turaco.

At the same time, TSMC has won all of Apple’s 5G RF chip orders, and it is expected to be used first in the iPhone 14 series to be launched this year.

If the news is true, we may soon see improved signal on the iPhone 14.

With the advancement of 5G technology, after solving a series of problems such as excessive power consumption, it will bring a better user experience.

At the same time, I believe that operators will gradually reduce 5G package charges, thereby lowering the threshold for 5G use.
