After each update of iPhone and iPad, everyone seems to be very sensitive to battery life – just after the update, there will be a process of system reorganization, so it will consume more power at the beginning. Since the recent iOS 15.4 update, despite the actual measurement by foreign media, theoretically, although some iPhone models have encountered battery life regression, in fact, most models seem to be improving (huh). However, in order to address everyone’s doubts, Apple quickly corrected what they considered to be “normal” battery life. Read on for the report on the iOS 15.4.1 minor update for iPhone battery life.
iOS 15.4.1 minor update for iPhone battery life
So do you really feel that you have encountered battery life problems after updating to iOS 15.4? The author has no obvious feeling, but since some people have actually measured that some models are affected. Apple is quite quick to release the corresponding update. The iOS 15.4.1 system update mainly fixes the following three issues, and the file size is said to be about 300MB:
· After updating to iOS 15.4, battery power may drain faster than usual
· Braille devices may not respond when viewing text or displaying prompts
· Made for iPhone hearing aids may lose connectivity in some third-party apps
Not surprisingly, everyone should pay the most attention to the first update project. Although foreign media are comparing the test results of iOS 15.3.1, the iPhone 6S made the most progress, with iOS 15.4 adding 39 minutes, followed by iPhone SE 2020 adding 34 minutes, iPhone 7 adding 14 minutes, iPhone 8 adding 9 minutes, and iPhone XR also increasing 9 minutes, iPhone 11 adds 21 minutes. However, it is reported that the iPhone 12 and iPhone 13 after iOS 15.4 have encountered a slight decline in battery life.
Therefore, you can see some complaints from users on Twitter, but Apple customer service also responded that it may be a normal adjustment mechanism of the mobile phone system. However, since the officials have released corrections, maybe this time iOS 15.4 still has some room for adjustment, so as to slow down the situation that the battery drains faster than usual. This time, iOS 15.4.1 also includes a fix for Braille devices and hearing aids that are interrupted and unresponsive.
As for the improvement in battery life, I believe it will soon receive returns from many users.
iOS 15.4 mainly adds the convenience of wearing a mask to unlock Face ID without relying on the Apple Watch. This feature is also mainly for the iPhone 12 and iPhone 13 models (maybe one of the reasons for the faster power consumption?). There are also new enhancements such as AirTag anti-tracking alerts, instant file integration in Notes and Reminders, adding notes to the key ring, universal controls and a whole host of new emojis.
