Update 15.4. 1 battery health.

Recently, Apple launched iOS 15.4, and this update added the long-awaited mask unlocking function. The size of the optical installation package exceeds 1G, so this update is a big upgrade. Many new features have been added, but this time Apple has subverted it. After updating iOS 15.4, many users said that the power was increased, the mobile phone was stuck, and the fever was serious. The expected mask unlocking function can only be realized on iPhone 13 and iPhone 12 series. There were many bugs after the update, and I cried with regret. In order to solve these problems, Apple introduced the iOS 15.4. 1 system. The update package size is 3 14.4MB, and there will be a slight gap between different models. Apple claims that this version includes bug fixes and security updates for iPhone, which is recommended for all users to install. It is clearly pointed out that bugs such as excessive battery power consumption have been fixed after updating iOS 15.4.

But is the truth really as good as Apple says? Ordinary users are advised to wait and see first, because some Apple users who have adopted early adopters have already started to spit out iOS 15.4. 1.

Judging from the current situation, after the update of ios 15.4. 1, the endurance has generally improved.

Some users commented that after playing the game all morning, it only used more than 30% electricity. The battery life is much better than before. Some users have commented that the battery life is better, but the battery health has dropped from 9 1% to 90%.

However, while alleviating power consumption, the latest bug appeared in iOS 15.4. 1. Some users feel that the battery life has not increased much, but the refresh rate of mobile phones has dropped. In many apps, Apple obviously limited the refresh rate, and there was a screen lock phenomenon, which felt less smooth than before.

There is also a user's reaction that it will flash back when it is turned on after the update, and the storage space is still turning, but it can't be displayed.

Even more deadly, even if the 5G signal is full, you can't connect to the Internet. You must manually switch to 4G before you have a network.

Moreover, after the update, after the actual measurement, all kinds of iPhone models, whether single-core or multi-core, have declined slightly, such as iPhone 13 Pro max, single-core 1743 and multi-core 4882 of iOS 15.4 system. In iOS 15.4. 1, the single-core running score is 17 17, and the multi-core running score is 4705. Obviously, the so-called bug of increasing power consumption fixed by Apple this time was obtained by reducing the chip frequency and limiting the refresh rate and signal of the mobile phone, and it also brought bugs such as flashback. So if you upgrade the previous version of ios 15.4, there is no problem. Then it is recommended not to follow suit, because iOS 15.4. 1 may have more fatal problems.
