At 1:00 a.m. Beijing time on September 17, 2015, the official version of iOS 9 began to be pushed. This time, the iOS 9 system has not undergone earth shaking changes in the interface. What we see is more new features of the built-in app, as well as small improvements in system settings. Let's see what iOS 9 has brought about? Do you want to upgrade?

Note: The device for updating iOS 9 is the Hong Kong version of 16GB iPhone 6 Plus

System aspects

New wallpapers for iOS 9

In terms of the system, the big version update of iOS will certainly usher in a new wave of high-definition wallpapers. I remember someone said that the wallpaper of a mobile phone largely determines the user's first impression of it. I think the wallpaper of iOS 9 this time is also pretty good. This time, a total of 12 wallpapers were added.

After the upgrade, many people will think about whether the available space of the mobile phone will decrease? Take the iPhone 6 Plus as an example. After upgrading from iOS 8.4.1 to iOS 9, the available space of the 16GB version is about 11.5GB. The total capacity has not changed much, but the available capacity has increased by nearly 600MB. So it is obvious that after this update, we will have more available space, which is a good news for iPhone users with small capacity. In addition, after updating the system, the CPU score has not changed, that is, the performance has not improved.

IOS 9 power-saving mode

This time, iOS 9 has an additional power-saving mode. The power-saving mode will pop up when your power is below 20% to remind you whether you need to update. At the same time, it can also be manually turned on in the system settings. The power-saving mode will turn off the downloading of background applications and the updating of background applications. At the same time, we also know that the main frequency of the processor in the power-saving mode has decreased.

At the same time, in terms of font, compared with the previous iOS 9 fonts, it is obvious that all the fonts have been thickened. I think that this sudden change of font is just a slight maladjustment, but I don't think that any kind of font is beautiful or not, so I have different opinions. At the same time, a search bar has been added in the settings to quickly search and find the functions in the settings.

This time, iOS 9 has added two more apps, one is to find iPhone, the other is to find friends. These two apps were originally downloaded in the App Store, but now they have become the iPhone's own applications. Photos have been classified in the photo album. There are self portraits and screenshots, which are easier to manage pictures.

New AssistiveTouch

On iOS 9, AssistiveTouch can add up to 8 button icons. Some common system functions can be added to AssistiveTouch, including screenshots, multitasking, double tap, screen lock rotation, and so on. The editor thinks that the screen capture function is very convenient, because the iOS 9 screen capture needs to press the power and Home keys at the same time. If the trigger screen capture cannot be pressed at the same time, the screen will be turned off. This quick screen capture can make the screen capture more stable and simple.

Use the sharing function of QQ music to jump to WeChat, and the button to return to "QQ music" will appear on the top left of WeChat

IOS 9 also has a return button this time, but it will only appear when you jump from one app to another through a special way, and it does not exist for a long time. It stays for about one minute. For example, I use a sharing function of the app to share content to social software such as WeChat or QQ, Then it will display a button applied before returning.

In addition, this time there is a new multi task control mode, but I don't know whether it is Apple's optimization problem or what the reason is, Compared with iOS 8.4.1, the iOS 9 multitask bar obviously feels frame drop when it is used, but this situation is only obvious on the iPhone 6 Plus at present. When I use the iPhone 6 at the same time, I will not feel obvious frame drop when I use the multitask bar, which may be related to the resolution of the phone, The physical rendering resolution of iPhone 6 Plus is 2208x1242, while the physical rendering resolution of iPhone 6 is 1334x750. However, this may be solved through later optimization.

In addition, Xiao Bian, as a heavy mobile payment user, relies on Alipay and WeChat for ordinary consumption, and many of their payment methods are code scanning. However, these payment scanning codes cannot be recognized on iOS 9 at present, and the above picture will appear after you scan the code. Whether you choose "Cancel" or "Copy Content", the code scanning cannot be successful, Unable to jump to the payment page, which may require the App to adjust for iOS 9 later. In short, the current situation is not available.

In terms of the system's own search bar, iOS 9 has enriched the function of the search bar and added a SIRI suggestion. SIRI suggestions include some software that the system has counted for your recent use, making it easier for you to quickly start them. At the same time, it has added "nearby", which can search some restaurants and entertainment places nearby.

The most important improvement of the search bar this time is to support the global search of all apps in the device, That is, when you hit "McDonald's" in the search bar, if you have Meituan or Volkswagen on your mobile phone, you will find some group purchase or evaluation information about McDonald's, but this requires third-party apps to add this function according to the new interface provided by iOS 9. However, these apps have not yet made changes for iOS 9, so I am making a small search " When Wallace was ", there was no content that could make a small editor laugh and talk.".

Weibo in iOS 9 automatically changes the language to English

After iOS 9 is updated, some apps in the system mistakenly think your system language is English, so they set the app's language to English along with your system language, which is a small bug, but you can change the language in the setting options in the app.

SIRI and its own App

SIRI in iOS 9 can only set short messages as reminders, which cannot be achieved on third-party apps

The SIRI of iOS 9 has become more intelligent. In short messages, we can call out the SIRI and say to it, "Remind me to see this in the afternoon". In sentences like this, we can set the content of the message as a reminder and let the SIRI remind us on time. When we tell the SIRI, we just say "this", SIRI It will automatically identify "this" as the content of the SMS you are viewing, or you are using "this event". It can still identify, but it is found that this function can only be implemented in the SMS of the system, in WeChat, or when viewing pictures, SIRI Can't add reminders for you. If this function can be applied to a wider range, it might be a good memo function.

Memos in iOS 9

In iOS 9, the system's memo can add more things, including photos, pictures, and handwritten memos.

New "Nearby" search function in iOS 9 map

Bus routes can finally be checked in the map of iOS 9

The biggest improvement of iOS 9's own app is its own map. This map used to be very lame. It has no other functions except positioning and navigation. Now iOS 9 has a lot of functions. It can now search some nearby restaurants, shopping and entertainment places, In use, we found that there are still many stores covered by this search function, and many unpopular stores can also be searched. At the same time, we can now use maps to find bus routes.

Although these new functions of maps have been implemented on third-party map apps for a long time, don't forget that this is a built-in map of iOS, which has unique advantages. It can be called out by the system with some functions, such as SIRI to help you find bus routes, but unfortunately it still doesn't support offline maps, Therefore, due to the high cost of mobile phone network in China, I still don't recommend you to use the self provided map of iOS 9 for a long time, but occasionally use it to install an *.

New "Wallet" App

The function of this Wallet is to save the QR code or barcode on your movie ticket, boarding pass, coupon, etc. by scanning the code. When you want to use it, click it, select the one you want to use, and it will display. Since there is no valid movie ticket, ticket, etc. on hand, I just scan the barcode of a cookie, It was found that it was unrecognizable, and it was also unrecognizable to scan some expired tickets online.

Some improvements in iPad

Split screen multitasking in iPad mini4 with iOS 9

Left: Apps that support multi task split screen Right: Apps that do not support multi task split screen

In iOS 9, there is also a new split screen multitasking function that has long been available in the Samsung Note series. This split screen multitasking function can be used when you start any application by placing the contact on the right edge of the screen and sliding left. This split screen multitasking will start. At present, split screen multitasking only supports iPad devices with 2GB RAM and more RAM. We use this split screen function in iPad mini4, At present, it supports some apps that come with the system, such as SMS and photo albums. At the same time, today's updated QQ and Office also provide support for iPad split screen multitasking.

However, if you are on an app that does not support split screen multitasking, the app on the other side will turn gray, which means that you cannot operate.

False split screen multitask in iPad mini3, the left app is grayed out and cannot be operated

On the device with 1GB RAM, the editor also tried split screen multitasking, but it was really OK, but the left app was in gray status and could not be operated, which may also be due to the problem of insufficient RAM, which would affect the operating experience. Apple made a fake split screen for the device with 1GB RAM, which seemed to be split screen, but actually the other app was not operable, Can only watch helplessly.

Maximize suspended video on iOS 9

Minimize the hover video on iOS 9 (the one in the red box)

The iOS 9 tablet device also supports the floating video function, but it also needs third-party apps to adapt. For example, the latest Tencent Video HD supports this floating video function. The floating video window can only be displayed in four corners of the screen (choose one from four). The window opening of the floating video can be adjusted, the maximum is shown in the above figure, and the minimum is really small, Let's see

In addition, this time there are some small details. For example, the SHIFT key on the virtual keyboard activates the letters on the keyboard to switch to the corresponding uppercase and lowercase letters. Each page of the iPad folder can display four lines and four columns of applications. Previously, there were three lines and three columns.

summary

IOS 9 is indeed a major update, but many of the updated functions of iOS 9 have already been implemented on Android, and iOS can only complete them today, but we should not forget that even if the same functions are placed on iOS and Android, there will be different experiences. This gap is caused by the closeness and stability of iOS, That is to say, iOS 9 is very necessary to upgrade from the functional point of view, but! But! After the upgrade of the iPhone 6 Plus, you can see the frame dropping of some apps with your naked eyes, that is, the iPhone 6 Plus has become more stuck after the upgrade, and these stutters are likely to be the reason for you to change your device, but if you want to say that it is very stuck, it is not impossible to use it. This time, some of the new features are practical and installation * compatible, For this reason, you may have to pay the price of changing the card of the machine (I'm not sure about the stuck situation after the iPhone 6 upgrade). As for whether to upgrade or not, you have different opinions.
