Apple's latest version of IOS 12.1.3 has been launched for several days, but many people have not updated their mobile phone system at the first time. Most people still hold a wait-and-see attitude and want to make a decision after determining whether it is worth upgrading. So is apple IOS 12.1.3 worth upgrading? What improvements and upgrades have it made on the basis of the previous system? Is the sense of experience better than before? Let's talk about the advantages and disadvantages of Apple's IOS 12.1.3 system and whether it is worth updating. Let's have a look.
In fact, the most important thing in this system update is to focus on solving the dual card and dual standby function of Apple mobile phone, and to fix some bugs in the signal. Therefore, it is necessary to upgrade Apple XR and apple xsmax mobile phones, and the improvement in the signal after the upgrade is still very obvious.
In terms of fluency, I think that after upgrading the latest version of IOS 12.1.3, the opening speed of mobile phone software has indeed improved a lot. The use of daily applications such as wechat headlines has improved a lot compared with the previous experience. The IOS system has been doing really well, but in terms of mobile phone life, I personally feel that it is not as durable as before, The battery can also be used moderately for a day. For those who go out in an emergency, they must bring a charging treasure.
In addition, in terms of stability, there is an essential improvement after the system upgrade of Apple mobile phone. Some daily bugs of mobile phone are very rare. Therefore, my personal suggestion for the version upgrade of IOS 12.1.3 is as follows. If it is apple 8 or above, it can be upgraded, but there is no need to upgrade too old models such as Apple 6.
Beta / public beta users upgrade ios12.1.3 official version
For users who have previously installed ios12 beta or public beta description files, the official version update cannot be detected because the version is beta or public beta. Since the official version of ios12.1.3 is higher than the previous version of ios12.1.3 beta 4 / beta 4, users of the public beta or beta version can also detect the update of the official version after deleting the description file and restarting the device, and then they can upgrade online through Ota.
Beta and public beta users only need to enter the "Settings" of IOS devices - & gt; "General", then slide to the bottom to see the installed "description file". Click "remove description file" to delete it.
After deleting the description file, restart the IOS device (iPhone / iPad), and then enter "Settings" - & gt; "General" - & gt; The official version of IOS 12.1.3 can be detected by "software update". Click "download and install" below to complete the installation and upgrade according to the prompts.
It should be noted that after deleting the description file, users of the beta / public beta version upgrade to the official version of ios12.1.3. Due to the broken version update, the update file to be downloaded for the upgrade generally exceeds 2GB. Therefore, it is necessary to ensure that the available space of the equipment is sufficient and try to carry out it in a stable network environment. In addition, the upgrade speed is also relatively slow. After all, there are many update files to download.
Upgrading through Ota is the simplest and most convenient. If you are not afraid of trouble, you can also upgrade by brushing the machine with the help of a computer. Brushing the machine mainly requires computers and software tools (such as iTunes), which is relatively troublesome. The old drivers who choose to upgrade the brush are basically old drivers, which will not be introduced in detail here.
How to downgrade the official version of IOS 12.1.3?
First of all, the degradation is similar to the brushing machine, which needs the help of computers and brushing tools, which is relatively troublesome. If you don't encounter something that particularly affects the experience, it is not recommended to downgrade the brush.
For those who need to be demoted, Xiaobian also briefly introduces the following steps:
1. First of all, the brushing opportunity leads to data loss. If there is important data on the IOS device, such as address book, photos, app, etc., please back up the important data in advance to avoid loss and facilitate recovery after successful brushing.
2. At present, the official version of ios12.1.3 can only be downgraded to the official versions of ios12.1.1 and ios12.1.2, and other versions cannot be downgraded. With the official release of IOS 12.1.3, the verification channel of IOS 12.1.1 will also be closed. Users who like this version should hurry to downgrade. Once this version verification is closed, they will not be able to downgrade to this version in the future.
3. There are two main ways to brush the machine. One is to use Apple's official iTunes tool to brush the machine for degradation (high security, but you need to manually download firmware), and the other is to use third-party brush tools, such as PP and aise (the operation is relatively simple and supports one click brush, which can avoid the trouble of downloading firmware).
4. Take iTunes tool as an example to introduce the general steps of brushing the machine:
ITunes brush downgrade method: 1. First download ios12 firmware for the model in the computer. For example, at present, the official version is downgraded, and only ios12.1.1/2 official version firmware can be downloaded; 2. Connect the IOS device that needs to brush to the computer through its own mobile phone data cable, and trust and authorize to connect to the computer; 3. Open the latest iTunes tools installed on your computer. If you have important data, it is recommended to complete the data backup first. 4. After the data backup is completed, press' Shift + update 'in the iTunes main interface, and then select to open the downloaded firmware, as shown in the figure;
5. After that, the operation will be handed over to the iTunes tool to complete it automatically. During the degradation process, please do not operate the computer and IOS device until the brush is completed, so as not to interrupt the upgrade and cause the device to turn brick.
Well, the above are the new features, upgrade and downgrade methods of the official version of IOS 12.1.3.
