After every iPhone and iPad update, everyone seems to be particularly sensitive to battery life – but right after the update, there will be a system reset process, so it will really consume more power for a while. Since the recent iOS 15.4 update, although through actual testing by foreign media, theoretically speaking, although some iPhone models have indeed experienced a degradation in battery life, in fact, most models seem to have improved (eh). However, in order to address everyone’s concerns, Apple quickly corrected the weakened battery life that they considered “normal”. Continue reading the report on the launch of the iOS 15.4.1 minor update to improve iPhone battery life.
iOS 15.4.1 small update for iPhone battery life is here
So do you really feel that you are encountering battery life issues after updating to iOS 15.4? The author has no obvious feelings, but since some people have actually measured that some models are affected. Apple released the corresponding updates fairly quickly. The iOS 15.4.1 system update mainly fixes the following three problems. 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 browsing text or displaying prompts
· Made for iPhone hearing aids may experience disconnection in some third-party apps
Not surprisingly, the first update project should be the most concerning to everyone. Although foreign media are comparing the test results of iOS 15.3.1, iPhone 6S has made the most progress, with iOS 15.4 adding 39 minutes, followed by iPhone SE 2020 with 34 minutes, iPhone 7 with 14 minutes, iPhone 8 with 9 minutes, iPhone XR with 9 minutes, and iPhone 11 with 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 official corrections have been released, perhaps there is still some room for adjustment in iOS 15.4 this time to slow down the battery consumption faster than usual. This time iOS 15.4.1 also includes corrections to the problem of interruption and unresponsiveness of Braille devices and hearing aid devices.
As for the effect of the improvements in battery life, I believe that we will soon receive feedback from many users.
iOS 15.4 mainly adds the convenient function of wearing a mask to unlock Face ID without relying on Apple Watch. This feature is also mainly for iPhone 12 and iPhone 13 models (maybe it is 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 your keychain, universal controls, and a bunch of new emojis.
