Important advice for iPhone owners to avoid the problem of the new operating system

Many iPhone owners have complained about their devices running out of battery quickly after downloading the new iOS 15.4 version.

"iOS 15.4 is draining battery like crazy, I'd say my battery life today is half what it was last week, I'm shocked," Alex Kretzschmar wrote in a blog post.

For his part, blogger Maxim Sheshko wrote: "The battery life with iOS 15.4 is really bad, the charging rate reached 80% after 24 hours, but the active screen time is only two hours... I only use Safari, YouTube, Instagram and Uber."

According to the many complaints issued by users of Apple devices, "the battery life no longer exceeds half a day on iPhone 13 Pro and Pro Max phones after downloading the new iOS 15.4 version."

 Some users of Apple devices expect that “the problems with the iPhone batteries are starting to appear because the new operating system uses the maximum screen refresh rate of 120 Hz within ProMotion technology in many applications.”

Apple has not commented on the complaints that have officially appeared yet, so technology experts advise iPhone owners who have not downloaded the iOS 15.4 version to wait until new software updates are released.
