5 false truths about 5G mobile phones, don't be fooled anymore

[[360004]]

Although some things are real, they are not necessarily the truth. Because if we look at them from different angles or with different standards, we may come to completely different conclusions, so you have to look at everything dialectically. Just like the emerging 5G network and 5G mobile phones, the following most common "false truths" may fool you.

5G consumes more power

This is indeed true. After all, no matter how powerful 5G is, it cannot escape the most basic laws of physics.

In fact, this statement was reflected before Qualcomm released the first generation X50 5G baseband in 2017. After all, the various optimization measures for 5G were not mature at that time, and the most advanced chip process level was only 10nm, which was two generations behind the mainstream 5nm, which is basically four natural years, the span from iPhone 8 to iPhone 12.

5nm chips will quickly bring 5G into maturity

Not only has there been a huge leap at the chip level, but 5G mobile phones generally have larger battery capacities. In addition, after 5G is commercialized, the industry has been conducting multi-dimensional joint optimization. Basically, any 5G mobile phone with a 5nm chip that you buy in 2021 will not have a noticeable experience degradation, and the soaring 5G network speed is real.

5G battery life diabetes insipidus

This is also true. The power consumption of 5G does increase, but battery life is a systemic problem.

In many 5G battery life tests, models such as the iPhone 12 have experienced the embarrassing phenomenon of "battery life diabetes". But it should be emphasized here that this test is generally a continuous 5G uninterrupted high-power output mode. This test environment tends to examine the polarity of the phone's battery life and is not directly equivalent to daily use. Moderate use and charging once a day is basically the norm.

The flagship phone battery life ranking is not closely related to whether it is 5G.

In fact, it is not just 5G. Even if the screen of the mobile phone is always on, or the CPU is always in high-frequency complex calculations, it will consume a lot of power. It is different if you use it at full load or intermittently. Again, as we are about to enter 2021, any mainstream 5G mobile phone will not make you feel a significant experience degradation. Don't treat engineers as fools.

5G radiation is greater

This is also true. For example, the iPhone 12 does have a higher radiation value than the previous generation model.

The introduction of 5G function has indeed increased the radiation value of the entire iPhone 12 series, and even the SAR value of the iPhone 12 mini is more than three times higher. The SAR value indicates the impact of the heat radiated by the mobile phone on the human body, and it is compliant within the national standard of 2.0W/kg. Although the absolute value of the iPhone 12 is higher, it still meets the standard. And this standard is very strict, and it is still safe within 50 times.

iPhone 12 radiation is indeed higher, but it is still safe

So is the radiation from 5G base stations stronger? According to academician Wu Hequan, the improvement of 5G network speed depends on the increase of bandwidth rather than the increase of transmission power. At present, both 5G base stations and 4G must comply with the national standard of less than 40 microwatts per square centimeter. For comparison, the US standard is 600 microwatts, while the sun can reach up to 100,000 microwatts.

5G is too expensive

This must be true, but Chinese people pay attention to the principle of "there are policies at the top and countermeasures at the bottom" when doing things.

If you log in to the official websites of major operators now, you will find that the lowest price for almost all 5G packages is around 128 yuan. And if you want a cheap 4G package, you can only go to an offline business hall to apply for it, and it is still unknown whether they can help you with it or whether you will be forced to buy a 5G package. The initial cost of 5G is high, so it is inevitable that it will be expensive.

Isn’t the free upgraded 5G network great?

However, Chinese people are very flexible in doing things. Now there are many ways to upgrade to 5G for "free". As long as you have a 5G phone and have activated the 5G function, most 4G packages can enjoy 5G speeds for "free". Even in some places, although the overall price of 5G packages is slightly higher, they also include more traffic and content, and the overall cost-effectiveness will be higher.

5G network speed explosion

After saying so many good things about 5G, we have to sing a counter-tune: although 5G is fast, it has also shrunk.

Regarding the issue of "reduced" 5G network speed, we need to look at it from two dimensions. Although many businesses will claim 5G speeds in various speeds, these may be based on theoretical values. Some even use millimeter wave band network speeds under ideal conditions to show, but in fact we currently only have the Sub-6GHz frequency band, and it is also affected by the environment and distance and has losses.

Even if the speed is reduced, it is still much better than 4G

Secondly, different tariff packages have different speed limits for 5G. If you want to experience the full-speed 5G network, you have to spend more money, and these high-end 5G packages are often expensive. For example, the peak speed of the 300M tier I use is 300Mbps, which is far from the theoretical speed of the full-speed 5G network. It is better to be rational and use it well, even so, it is much better than the stuck 4G!

The last sentence concludes: Whether you support it or not, 5G replacing 4G is an irreversible trend. Just let the 5G upgrade take its course. It is not as strong as exaggerated, nor as bad as the legend says. 5G, that's all~
