Xiaomi mentioned on the official website very early that Xiaomi 5X and MIUI 9 will be released in Beijing today, as well as a Xiaomi AI speaker (this is a small surprise), but since Xiaomi 5X will not be introduced in Taiwan, the possibility of introducing Xiaomi AI speakers is also Small, so let's focus on MIUI 9! (~Real ghost~ Okay, the speaker is worth introducing, I will write later)

MIUI 9 will release the development version for Xiaomi Mi 6, Xiaomi Mi 5X and Qualcomm version of Redmi Note 4X on 8/11.

Then from 8/11, popular models such as Mi MIX, Mi Note 2, Mi 5, Mi 5s plus... can also update the development version.

The third wave is in late September. The B32-1070 allows all Xiaomi and Redmi models except Mi 1/1s and Mi 2A to be updated, including Mi 2 and Mi 2s (launched in 2012 and 2013). It's amazing that a phone that's 5 years old can still be updated).

Xiaomi mentioned at the press conference that there are 50 models of Xiaomi and Redmi phones that can be updated.

However, the international version of MIUI 9, which is related to us, is currently asked if an update is expected to be released after September, but some of the functions involved in searching the database and app docking (such as portals) will also continue to the international version. Not sure (although I personally think the possibility is a little small).

MIUI 9 is developed based on Android 7.1, and "fast" is the main direction of this update.

Before the publication, Xiaomi mentioned that they have done some sorting out for the system functions of MIUI 9, and streamlined some unnecessary and low-usage, more than 50 system functions (may be rearranged, not necessarily cancelled), and improved system hypertrophy. , including cloud business card, caller show, children's mode (replaced with clone mode), Xiaomi Yellow Pages, etc., have been adjusted appropriately.

A lot was disclosed at the press conference, including the basic experience and new features.

Basic experience includes:

Speed up program startup,

Optimize dynamic resource allocation,

Multiple system performance optimizations

Three new features were highlighted at the press conference:

photo lookup

information assistant

portal

1. Program startup speed

Hong Feng, one of the founders of Xiaomi, mentioned at the press conference that the speed of program startup is an assessment of the explosive power of the system. MIUI 9 speeds up program startup by optimizing touch response speed, CPU growth rate, and thread scheduling.

How does Xiaomi show the startup speed? Compare directly.

Xiaomi used Mi 6 equipped with MIUI 9, and Galaxy S8 and Huawei P10 to compare the opening speed of 50 popular programs, including WeChat, iQiyi, Weibo, Taobao, etc. Among the 50, MIUI 9 has 43 updates. Quick start, and move out of the notary's certificate for endorsement.

Dynamic resource allocation means that when we use an app in the foreground, there are actually many programs running in the background, such as WeChat, email, etc. waiting to receive new messages or updates, so the system can be smart It is important to allocate resources to the programs that users are using.

MIUI 9 has optimized resource allocation.

Xiaomi still takes out MIUI 9 + Mi 6, and compares it with Galaxy S8 and Huawei P10.

Let the three mobile phones download programs in the background at the same time, while the front desk is watching news/playing games, and see the reaction speed and smoothness of the three mobile phones when watching news and playing games.

Looking at the news test, under high-speed photography, you can see that when the content of Xiaomi Mi 6 appears, the other two are still loading.

When playing online sparring games, the background is downloading programs at the same time, and both jobs are using the network, but the delay time of MIUI 6 connection when playing games is not affected.

Multiple system performance optimizations

Xiaomi mentioned that MIUI 9 has been optimized in so many aspects, such as continuous automatic cleaning, abnormal elimination mechanism, reduction of memory fragmentation, etc. All together, it provides a long-term use and still maintains a smooth experience.

According to the data of big data, Xiaomi simulated a 6-hour user usage situation and used some common functions. When the machine operated these functions, it recorded the sum of the delay time greater than 100ms during the process. It is conceivable that the higher the sum, the higher the more delays.

The comparison results are as follows. MIUI 9 + Xiaomi 6 have the shortest delay time. Xiaomi emphasizes that these are all certified by a notary.

In addition to the basic experience, MIUI 9 also mentions 3 new biggest functions.

First photo lookup

You can enter keywords, and after the album is automatically recognized, you can find matching photos in a large number of photos.

The keywords can be people (with facial recognition), time, place, expressions, documents, and more special, the text in the screenshot can be recognized to find the screenshot. (It should still be matched with some manual naming settings for characters)

Those who have experienced Google Photos or iOS Photos should not be unfamiliar with these functions. Through machine learning, the system will automatically identify the features, scenes, people, time, objects, etc. in the photos to help you find photos. In fact, You enter "smile" in Google Photos, and Google Photos will automatically fish out photos with smiling faces, enter "ID card", and it will also find ID photos.

The smart search of Google Photos is already very mature, but it is still not possible to recognize the text in the screenshots to find photos, so this is a very special MIUI 9 photo album.

Because it involves recognition and machine learning databases, I don't think the international version of MIUI 9 will have it, but because we can use Google Photos, it's actually just as powerful.

Second, the information assistant

We often see a lot of articles, news, messages, etc. in various apps. If we are interested, we will click on the favorites, but each app is individually favorited, which means no favorites. In the end, we should not remember that the message is In which app. The information assistant function is designed to solve this problem.

No matter which app you click on the favorites, these contents will be listed on the negative screen of the desktop (the screen that appears when you swipe to the right), and all the favorites are here.

The third, "Portal"

Literally it seems to be used for file transfer, but it is not. It is a function that automatically recognizes keywords and brings out the associated App.

In a chat or a webpage, copy a word, address, etc., it will recognize what it means, and then automatically find the associated App.

For example, the chat talks about restaurants, meals, and what to eat. After long-pressing on it, the app will automatically bring up the Dianping app, telling you this restaurant and where there are places that sell this meal nearby...

Ok, since it is related to some third-party programs, or regional apps, the chances of the international version are small.

However, this is quite similar to Google's "screen search" function. After enabling this function, long press the Home button on any screen, and he will detect what text is in the current screen, and then bring up the relevant Google App to let You move on to the next action. For example, an address is detected, a Google map appears, a star, a video name is detected, a search, a knowledge map, YouTube, etc. are displayed, or you can also select a text and let it search.

However, the automatic docking here is still Google's own App, but usually you can simply copy the text and use the sharing method to search in the third-party App. For example, if you want to find delicious beef noodles in Neihu, choose Public Comment in the share. Keep searching.

Therefore, if you want, the international version can be replaced by Google screen search, but the ease of use still depends on how well it connects with third-party apps. At present, it seems that Google does not connect with many third-party apps, so it is easy to use. Somewhat average...

Has MIUI 9 done better? If someone in the mainland has tested it, please share it with us.

These three new functions use a lot of recognition technology. Although there is no mention of machine learning or AI artificial intelligence at the conference, I want to identify a lot of information. Without these two technologies, there are also It is difficult to achieve the backing of a huge database. Perhaps MIUI 9 and the Xiaomi AI speaker released at the same event can also be regarded as Xiaomi's artificial intelligence product achievement conference.

But when it comes to the database, there is the issue of whether it is applicable to the region. For those of us who use the international version, these database-related functions may be removed (but the news before the final update is the most accurate).

Although it's a pity, at least performance and speed optimization are still very useful. System stability is the most basic, isn't it?
