Analysis of ios system knowledge:

As Apple continues to launch new operating system versions, many iPhone users will face a common question: whether they should upgrade their devices to the latest version of the system ?

Apple has launched an update to iOS 17.4.1, which has made many iPhone 13 users hesitate to upgrade. So, as users of Apple 13, should we upgrade to iOS 17.4.1? This article will give you a comprehensive explanation.

First of all, from the perspective of battery life performance, iOS 17.4.1 has not brought significant changes to the battery life of Apple 13. According to tests, the battery life of the upgraded Apple 13 is basically the same as that of the iOS 17.4 version, with no obvious improvement. This is undoubtedly bad news for those users who have higher requirements for mobile phone battery life.

However, there are some changes in signal stability. Compared with the iOS 17.4 version, the mobile operator's signal has dropped slightly in iOS 17.4.1, but the change is not significant and the connection status is still relatively stable. The signal of China Unicom operator has been slightly improved, but the perception is not obvious. Telecom operators' signals remain unchanged. For most users, such signal changes may not have much impact on daily use, but if you are a user with extremely high requirements for signal stability, you may need to carefully consider upgrading.

In addition, iOS 17.4.1 has also made achievements in fixing bugs and improving security. The new system solves the problem of the iPhone being unable to enable the "auto-correction" function, which is very practical for some users. However, some users have reported that battery life and health have decreased after the upgrade. Therefore, before upgrading, you need to weigh the benefits and possible risks of the new system.

In addition, iOS 17.4.1 has also been optimized in terms of 5G signals, especially in environments with weak signals, such as in elevators. The new system solves the 5G signal problems that existed in previous versions. However, it should be noted that although the signals of China Unicom operators have improved, overall, the signal stability has not achieved the expected significant improvement.

In addition, after upgrading to iOS 17.4.1, the overall system performance of Apple 13 did not achieve the expected significant improvement. Especially when it comes to battery life, users may notice a decrease in battery life. At the same time, phenomena such as heating, frame drops, and freezing may occur when playing games. Therefore, if you are a game-loving user, you may want to carefully consider whether to upgrade.

To sum up, for Apple 13 users, whether to upgrade to iOS 17.4.1 depends on your personal needs and preferences. If you value system stability and security and are not particularly sensitive to battery life, upgrading to iOS 17.4.1 may be a good choice. But if you are already satisfied with the current system, or are worried about possible signal and battery life problems after upgrading, you may also consider not upgrading for the time being.

In the new iOS 17.5beta3 version launched by Apple, the signal has been significantly improved compared to iOS 17.4.1. In outdoor scenes, China Unicom’s dual SIM cards can maintain a full signal, even in elevators or office buildings within an acceptable range.

The new version showed a higher battery retention rate in the battery life test. When playing games, the phone's frame rate is more stable and the frame rate will not drop. This is for users who use mobile phones for a long time. Undoubtedly a very important improvement.

In addition to the obvious improvements mentioned above, iOS 17.5 Beta3 also introduces some potential new features. For example, support for third-party project trackers may provide users with more information about nearby trackers, further ensuring personal privacy security. At the same time, the possible new "block all participants" option in FaceTime group calls is also expected to provide users with a more flexible and secure calling environment.

Here are the upgrade methods:

1. To prevent unexpected situations, please back up all data in the device (full backup) before upgrading.

2. After upgrading, you cannot downgrade back to the iOS version that Apple has officially closed for verification.
