At the beginning of August, the multi pro AI function mobile phone launched by Duopro Technology Co., Ltd. was put on the shelves of Mijia crowdfunding. Although it is not the current popular smart phone, its unique positioning has attracted many users' attention. As a functional mobile phone that focuses on the elderly and standby, can it capture users?

appearance

Duoqin AI functional mobile phones are similar to most products in the shopping mall in terms of external packaging. They are packaged in white main colors. The front is a rendering of the product, and the back is some relevant parameter identification of the product.

After opening, you can see the body. Although there are only instructions, data lines and pins on the accessories, the manufacturer has provided plastic packaging protection for mobile phones and accessories. We got the iron gray 4G version, the specific model is Qin1s (the 2G version is Qin1).

The Qin1s adopts a very popular straight board shape, equipped with a 2.8 inch 240x320 display (the same specification as the Nokia N95 8GB), T9 keyboard and regular navigation keys, which can be said to be very nostalgic. Because Qin1s is designed with a non detachable battery, its back is highly integrated and uses a skin like coating. It is believed that sharp eyed users have also found that Qin1s does not have a rear camera, nor is it equipped with a 2 million camera symbolically like Nokia's recent 3310 and 8110.

The physical T9 keyboard has a large contact area of each key and a good feel. In actual use, the navigation key part is somewhat crowded. I believe it would be better if you could replace it with a touch pad or rocker design.

The top of the Qin1s is specially equipped with infrared, and the function of infrared remote control is built in. Even if it is not a smart phone, it can also control different household appliances at home. It is especially practical when the remote control is temporarily unavailable and has no power.

The bottom adopts a symmetrical design, and the microphone and speaker are separated on both sides. It is commendable that Qin1s uses USB Type-C on the data interface. In the case that Type-C interface is widely used in smart phones today, it is unnecessary to prepare an additional data cable with different interfaces when Qin1s go out as a standby.

The design of the non detachable battery enables Qin1s to arrange a card slot on the left side of the fuselage, while no elements are arranged on the right side of the fuselage. In actual use, for example, the volume can be adjusted through the navigation key in the call state, but I feel that setting the volume key on the right side will be more consistent with everyone's use habits, which is a shortcoming.

screen

Qin1s is a 2.8 inch IPS screen, and its PPI is "only" 142, which is a big gap compared with the popular FHD and even 2K and 4K resolution HD screens of smart phones today. Fortunately, the surface of the Qin1s screen is covered with gorilla glass, which does not use plastic like the original functional machine. In addition, the system itself can render the font well, and the default font has a strong sense of burr when using Symbian before.

The brightness of the Qin1s screen should have no problem in the outdoor environment, and it can be basically maintained at 50%~60% in daily use. After all, Qin1s is a product targeted at the standby machine, which is acceptable.

system

In terms of the system, the 4G version of Qin1s uses MOCOR5 (the 2G version of Qin1s is Nucleus), and the overall interface maintains the original familiar style of Jiugongs, without difficulty in getting started. For some elderly people who are not used to smart phones, the system interface is obviously more familiar and simple, and the font has also been targeted to a certain extent. As for the overall response speed and smoothness of operation, it is satisfactory. There is no obvious "stuck", but it is certainly not as smooth as the flagship mobile phone.

What distinguishes Qin1s from other functional phones is that Xiaomi's voice assistant, Xiaoai, is built in, through which the voice control of smart phones is realized. Most of the daily operations, such as making a phone call and setting an alarm clock, can be realized by Xiao Ai, but the slightly more complicated commands like turning on hot spots and turning on infrared remote controls cannot be recognized. At the same time, in order to strengthen the function of Xiaoai students, Qin1s has built-in voice translation, audio content and other unique options to meet more user needs.

It should be noted that the 4G version of Qin1s supports dual cards and dual standby, but only the primary card supports 4G networks, and the secondary card can only support 2G networks. Because there is no CDMA in the supported frequency band, the telecom card cannot be used. If dual card 4G or telecom users are required, Qin1s cannot meet the requirements.

Endurance

In terms of battery life, the official said that the Qin1s is equipped with a large 1480mAh battery. The 4G version of the Qin1s can stand by for 7 days, and the 2G version of the Qin1 can double to 15 days.

Of course, the official data is generally ideal. How about the actual use? When the dual card is inserted in standby mode for one day, the brightness is 50%, during which there are 30 minutes of calls, 30 minutes of hot spots, and 10 SMS messages. The power consumption is about 20%. When the battery is fully charged, it can basically be used for 5 days. This endurance is believed to meet most users. For more extreme use, it can last for 6-7 hours when the 4G hotspot is turned on in the whole process. Even if it is used as a special sending hotspot terminal, it is OK.

summary

In general, the Duoqin AI mobile phone Qin1s is qualified as a standby phone and an elderly phone, and the addition of Xiaoai's classmates and the infrared remote control is a plus point. The price of 299 (199 for the 2G version of Qin1) is also superior to the functional phone recently launched by Nokia. The shortcoming to mention is that it does not support dual card and dual 4G, and the appearance is simple and not so coquettish. If you can accept these shortcomings, Qin1s is a good choice.
