As a senior mobile phone enthusiast, I know that only a high degree of combination of software and hardware can produce good results and improve the user experience of the mobile Internet. Based on this idea and ideal, and a group of entrepreneurial partners with passion and dreams, we have promoted The driving force behind making Xiaomi mobile phones.

Edit this paragraph Xiaomi after-sales service

[4] Li Wanqiang, co-founder and vice president of Xiaomi mobile phones, said at the media communication meeting that Xiaomi mobile phones comply with the national three guarantees policy. After-sales service will be done by door-to-door return or exchange, or return to the factory for repair. The door-to-door return and exchange service for Xiaomi mobile phones will be provided by Vanke's "Rufengda Express", covering more than 20 cities across the country. After the user contacts the Xiaomi customer service hotline to confirm that the phone needs to be returned to the factory for repair, the courier can pick it up at the door. In addition, Xiaomi will open some self-inspection points in the future to help users detect whether problematic mobile phones need to be returned to the factory for repair. Later, Li Wanqiang stated on Weibo that the complete after-sales service policy will be announced before shipment in October.

Xiaomi officials stated that in the initial stage, purchases will be made according to the order in which the reservations are queued. The details of the reservation event are as follows: 1. The queue will open at 13:00 on September 5, 2011: On September 5, only those who registered a Xiaomi account before August 31, 2011 (excluding August 31, 2011) are eligible Book in line.

Xiaomi officials will also add another reservation channel - 5,000 places reserved for senior rice fans.

This 5,000 quota is independent of the public queue, that is, it does not preempt the normal queue qualifications. It is another reservation channel. As long as old users of the Xiaomi Forum who have reached 100 points before August 16, click on the queue to be prioritized in the 5,000 reserved positions. , and only queued up with everyone when the 5,000 reserved spots were full.

Xiaomi mobile phones (19 photos) can be purchased with direct payment without reservation after December 2011.

Negative limited sale

According to Qualcomm senior officials, Xiaomi’s first batch of processors ordered from Qualcomm is “10K”, which means that Xiaomi’s mobile phones will not be sold in volume this year. The quantity produced will not exceed 10,000 units. At the Xiaomi mobile phone launch conference on August 16, 2011, Lei Jun used "Our first goal is to satisfy users, not sales" to avoid specific mass production data. (According to Da Li’s rumor-refuting answer on the latest Xiaomi forum, after the official launch, Xiaomi will not limit the quantity)

Battery

The battery is 1930mAh, yes, but judging from the engineering machine, The battery says 1880~1930mAh, which is 50mAh different from the advertised 1930mAh. In this regard, Xiaomi explained that 1880mAh is the lowest value and the average is 1930mAh. It is normal to have a certain difference between the two. For this reason, It solved some people’s doubts.

Disrupting the Industry

Industry insiders believe that Xiaomi mobile phones may subvert the old mobile phone manufacturing industry. The price of Xiaomi mobile phones alone is enough to cause a huge impact on the mobile phone industry. "With such configuration and price, it can be seen that Xiaomi does not want to pass Mobile phones are profitable; on the other hand, it can also be seen that the traditional mobile phone industry has caused the additional costs of mobile phones to rise due to factors such as stores and channels, and these costs are ultimately passed on to consumers. "Xiaomi's Internet development and sales model of mobile phones. In addition to being closer to user needs, more importantly, it is also closer to users' wallets while ensuring quality. "The person bluntly said that China's mobile phone industry has gone through several rounds of changes in the past decade, and the development of iPhone and Android has changed. The rules of the game in the mobile phone industry. Terminal standardization and integration are becoming more and more mature. Terminal competition is no longer the core of the mobile phone industry. The user experience provided by terminal content and services is the top priority.

MIUI

MIUI, which was born for mobile phone enthusiasts, is a deeply customized Android mobile operating system under Xiaomi Company. It is also the mobile operating system of Xiaomi mobile phones. MIUI has been launched since June 1, 2010. Officially established on the same day, it has made more than 100 improvements to the native Android system. It has users in 23 countries and is updated weekly. It is extremely popular among mobile phone enthusiasts. MIUI is updated every week and currently has 300,000 active users. Baidu has included 2.5 million MIUI pages, and Google Global Xiaomi Mobile Review

[6] has included 7.2 million MIUI pages. MIUI itself has only one Chinese language version. Thanks to DIY transplantation by enthusiasts, MIUI users cover 23 countries around the world and have fan sites in 11 countries around the world. It is highly sought after by enthusiasts at home and abroad.

Summary: It would be a bit untrue to simply say that the CPU frequency can determine the positioning of a mobile phone. From the perspective of various components, Xiaomi mobile phones probably don’t have anything top-notch except the CPU, but if each component reaches a relatively high level, it can be regarded as a high comprehensive power. If I have to say there is something worth showing off about Xiaomi mobile phones, I would think it is its price of 1,999 yuan. As for why? No need to explain.

Can be upgraded to Android 4.0 system

Although Xiaomi mobile phones have powerful functional configurations, people are also concerned about whether there are restrictions on system upgrades in the future. According to the technical personnel of Xiaomi Technology revealed at the media meeting, Xiaomi mobile phones will provide users with Ice Cream Sandwich, the legendary Android 4.0 system upgrade service, so users who buy Xiaomi mobile phones do not have to worry too much about the native Android of the mobile phone. System update problem.

Ideal mission

To make a smartphone that is loved by mobile phone enthusiasts and gamers!

The reason for its birth

When talking about why he made Xiaomi mobile phones, Lei Jun, the founder of Xiaomi, said that he had run and invested in companies in the past, and his life was already very complete. In his 40s, he felt There is still something we can do. Judging from the current development trends, China will be a mobile Internet world in the future, and smartphones and applications will carry most of the needs of users. Although I have spent a lot of money on mobile phones in the past many years, from various series of mobile phones produced by Google to Nokia, Motorola, Samsung, and now IPhone, there are many problems during use such as poor signal and disconnection in broad daylight. Waiting for dissatisfaction. As a senior mobile phone maniac, I know that only a high degree of combination of software and hardware can produce good results and improve the user experience of the mobile Internet. Based on this idea and ideal, and a group of entrepreneurial partners with passion and dreams, we have promoted The driving force behind making Xiaomi mobile phones.

The hardships of creation

Lei Jun talks about the hardships behind the scenes of Xiaomi mobile phones: he has been humiliated in every way

On August 19, with the release of Xiaomi mobile phones and Lei Jun (Weibo) With a Steve Jobs-like appearance at the press conference, Lei Jun and his Xiaomi team attracted great attention from the industry, and this mobile phone, which has been hailed as a fighter among smartphones, is also highly anticipated. However, behind the scenery, the hardships of Xiaomi team’s development cannot be concealed. According to Lei Jun, Xiaomi was humiliated by Fortune 500 companies in every possible way when it was developing mobile phones at the end of last year. for example. The company was established less than a year ago, but the other party asked for three years of Xiaomi's financial statements and went through complicated procedures. In the end, the cooperation between the two parties often failed. Lei Jun said frankly that at the beginning, I hated suppliers with all my teeth. Later, I began to understand the difficulties of suppliers, and started to change my philosophy in several aspects. For example, for mobile phones, you don’t just buy a few chips and solder them on the board. Many devices are actually customized and require the supplier to pay upfront development costs. [7]

Copycat Questions

The high configuration and low price of Xiaomi mobile phones have caused some people to refer to them as "copycat phones". Xiaomi Technology founder Lei Jun personally said in an exclusive interview with domestic media Drop your phone from the air and use quality to refute the claim that Xiaomi is a copycat. Lei Jun said that he originally planned to use the waveguide to make a joke in the promotion, saying that Xiaomi is a fighter jet among mobile phones. Unexpectedly, some netizens first proposed the idea of ??copycat. Lei Jun said that the quality of Xiaomi mobile phones has been professionally inspected and performance tested, and a lot of money has been spent in this regard. The manufacturing process of ordinary knock-off phones is unimaginable. He said: "Why can't we compare with parallel imports? It's because they don't pay these taxes, and parallel imports of mobile phones don't have so many tests." Lei Jun revealed that the testing equipment of Xiaomi mobile phones includes those purchased by itself and rented from third parties, while copycats It is impossible to go through these details in the production of machine. After the Xiaomi mobile phone fell freely from a height of about 1.5 meters, it could still be turned on normally when picked up, and all functions were not affected. Lei Jun said that Xiaomi mobile phones are large-screen smartphones and are very delicate, so they need to undergo drop and other related tests. In fact, as early as after the press conference on August 16, Lei Jun dropped a Xiaomi phone once in front of many reporters. He dropped it again this time. It seems that Lei Jun has no doubt about the quality of his products.

Lei Jun said that Xiaomi mobile phones will open flash settings, and the official website will provide MIUI and Android native systems. In the future, MIUI will also support other brands of mobile phones.

Mobile phone performance

Xiaomi mobile phone uses the MIUI system based on Android 2.3.5 deeply customized modifications. Xiaomi mobile phone uses Qualcomm 1.5GHz dual-core CPU, Adreno 220 graphics chip, and is equipped with 1GB RAM memory, 4GB body storage, and supports 32GB MicroSD. The mobile phone screen uses a 4-inch 16:9 screen with a resolution of 854×480 and a screen width of 63mm. The battery capacity is 1930mAh. According to official data, this battery has a network standby time of up to 450 hours, supports 15 hours of continuous calls, 45 hours of song playback, and 6 hours of large-scale games.

In terms of communication system, Xiaomi mobile phone supports 7 frequency bands including GSM WCDMA; supports two satellite systems, American GPS and Russian GLONASS. Xiaomi mobile phones place the GPS and WiFi Bluetooth antennas on both sides of the top of the fuselage respectively, and the GSM antenna is placed at the bottom of the fuselage, so that the communication signal will not be affected by holding it in the hand. Dual system switching Xiaomi mobile phone press conference once mentioned that they will bring unlocked dual system support to this phone. The phone will be flashable. The official website provides two applicable versions of MIUI and native Android for users to choose and use. MIUI will be bound to Xiaomi phones. This is an officially supported free flashing design. In addition, Xiaomi mobile phones also have a more powerful dual-system switching function. In the About mobile phone interface in the mobile phone settings, press the menu key, and the switching system interface will appear. This is the built-in dual system free switching function specially designed for Xiaomi mobile phones, but MIUI and the native system cannot be switched between each other.

Mobile phone system MIUI

Xiaomi mobile phones use MIUI and are deeply developed based on the Android 2.3 native system. We strive to have the best phone and text messaging experience in smartphones and adapt to the usage habits of Chinese users. , a complete UI system with original features. A better text messaging experience. Compared with the native Android system, 7 major details of optimizing text messages: optimizing the way to add contacts in new text messages, supporting adding a title when sending group messages and automatically storing it as a contact nickname, etc. Xiaomi mobile phones are open to free flashing. Users can choose to automatically update and flash their phones via computer, WLAN or mobile phone. Xiaomi mobile phones use dual systems. There are two types of dual systems, one is unlocked dual system, and the other is dual MIUI system (switching). The so-called "unlocked dual system" means that Xiaomi mobile phones allow users to freely use the MIUI system and Google's native Android system without any restrictions. But users can only choose one of the two, and users can freely choose between the two systems multiple times. Of course, this requires the user to flash the phone, but the user's personal data and information need to be backed up in advance, otherwise all will be lost. Dual MIUI system means that when the user chooses to use the MIUI system, he can install two MIUI systems at the same time and can freely switch between the two systems (requiring to restart the phone to select the switch). The two systems are independent, but their databases are universal, that is, after system A is modified, the modified data will be the same after switching to system B. Dual MIUI system is a unique technology of Xiaomi mobile phones, and its biggest selling point is the anti-flash function. For example, when I have a problem with system B and crash, I can re-flash system B through system A, and the original data will still exist. And if there is a problem with both systems, it can be restored through a physical restore key. It should be noted that the premise for the existence of these two MIUI systems is that the versions of the two systems are relatively close. For example, version A of the MIUI system is developed based on Android 2.3.4, and version B of the MIUI system is based on Android 2.3. .5, then these versions A and B of the MIUI system can be saved. And if the C version of the MIUI system is developed based on Android 4.0, then there is a high chance that the C system will not be able to survive the first two. This is because the versions are too different and there may be new changes in the system file format, so compatibility cannot be guaranteed.
