Apple officially released iOS 9, which seems quite tempting

Fans can breathe a sigh of relief. After several months of beta release, Apple finally officially released iOS 9 today. The new system supports a wide range of devices, including iPhone, iPad and iPod Touch. To upgrade, please enter the "Settings" menu, click "General", and then select "Software Update".

Compared with iOS 8 and Yosemite, the biggest difference between iOS 9 and El Capitan is the fonts from Apple Watch. For English, iOS 9 and El Capitan use San Francisco fonts, while for Chinese, Apple chooses to launch a new font "Ping Fang". If you are used to the font of iOS 8, the Ping Fang font still feels very clear, and the small size font looks clearer. Of course, with use, the feeling of discomfort caused by the font change will disappear.

The updates brought by iOS 9 are mainly divided into four major parts: upgrading built-in apps, improving iPad experience, making it smarter, and updating the underlying system. In iOS 9, new features will be added to the familiar apps we use daily, and the underlying system will also be upgraded, making the overall experience smoother, more power-efficient, and safer. The functions of iPad iOS 9 make it easier to perform multitasking on the tablet. I believe that many functions are also prepared for the upcoming iPad Pro, which requires high hardware configuration to use all the functions.

Specifically, iOS 9 is smarter and more power-efficient. The previously useless Siri has been upgraded to have smarter search and usage suggestions. The integrated search function can be seen by swiping left on the main screen. There will be "Siri Suggestions" and "Nearby", both of which are recommendations based on user usage habits. A while ago, Siri also added Baidu Encyclopedia search results, making this voice assistant more useful.

In terms of power saving, Apple officially announced that iOS 9 can add 1 hour of battery life with normal use, and up to 3 hours of additional battery life can be obtained by turning on the low power mode. It still sounds very tempting.

In terms of some native functions, Apple has also spent a lot of effort on innovation, and it seems to be competing with third-party applications. For example, memos can add photos, maps or links, and you can also write and draw. Safari can be used as an attachment to documents or memos through the sharing function, opening up horizontal connections between applications. Apple Maps has added a bus route planning function, and explicitly supports multiple cities in China. In addition, iCloud Drive, Mail and other applications have also been upgraded.

For iPad users, iOS 9 is even more of a "must-have" because it has finally developed usage scenarios suitable for large-screen devices, namely split-screen and picture-in-picture.

The split screen function allows iPad to process two windows at the same time, and the ratio of the split screen can be adjusted. You can even drag the content on the left to the right area, just like a computer. The picture-in-picture function is completely for video playback and Facetime. You can do two things at the same time, and the content of the picture-in-picture can be dragged and dropped at will. However, these two functions currently only support native applications, and third-party programs need to be adapted.
