The iOS 15.4 system update has an impact on device battery life. Apple officially responded and shared tips for improving iPhone battery life.

Apple recently released the official version of iOS 15.4, launching a series of exciting new features. However, some users have reported that this version consumes too much power. I hope Apple can solve this problem as soon as possible to improve the user experience.

According to feedback from some users, they encountered poor battery life after OTA upgrade. They found that the iPhone 11's power consumption reached 80% within 24 hours, but the actual screen use time was only 2 hours. Similarly, the iPhone 13 Pro Max can only last half a day.

Apple’s support team today responded to complaints that the latest iOS 15 update was causing iPhone batteries to drain too quickly. Although it's unclear how many iOS 15.4 users are affected by the issue, Apple has explained it and provided some advice.

Apple support claims they are not acknowledging any unusual battery drain issues. Apps and some phone features may need some adjustments during the first 48 hours after installing a new version of the operating system, so changes in battery life are normal. It is recommended that users observe the issue for a period of time and contact Apple support again if the problem persists.

Many netizens expressed dissatisfaction with Apple’s response and thought their remarks were too perfunctory. They hope Apple can solve the problem as soon as possible. Have you encountered similar problems?

In addition, for users who have upgraded to iOS 15.4 and encounter serious power consumption problems, you can refer to the following power saving settings. The editor has tried it personally and the battery life has been significantly improved.

First of all, we have to make one thing clear: after the system upgrade, some data migration and optimization will be carried out, which will inevitably lead to a certain degree of power consumption and heat generation, but this is a normal phenomenon. Usually after a few days of use, things will return to normal. Therefore, if you have just upgraded your system, I recommend you to use it for another two days to test, maybe there will be an improvement.

A little trick for iOS upgrade is to use wire brush to upgrade, which is more stable than direct OTA upgrade. The so-called wire brushing is to upgrade the mobile phone through the computer. Based on my experience and feedback from many people, the likelihood of problems occurring after a line brush upgrade is very small. Therefore, if you have encountered a lot of mobile phone problems recently, you can try to use the Apple mobile phone repair tool to perform a wired upgrade of your Apple device. This may solve some problems.

Apple Phone Repair Tool is a standard repair tool that can repair various iOS system-related issues without losing phone data.
