IT Home March 21 news, earlier this week Apple pushed the official version of iOS 15.4, bringing the use of masks to use Face ID function, as well as new emojis, as well as a large number of bug fixes, but many users reported that the phone life has deteriorated after upgrading the new system.
Some users on Twitter and Reddit say their phones' battery life has dropped faster since the iOS 15.4 upgrade. At present, many posts mention that the latest iPhone 13 model has been affected, but others have also mentioned that Apple's old mobile phones are also affected.
IT House understands that this doesn't seem to be a common problem, as there are other Reddit and Twitter posts saying that iOS 15.4 improves their phone battery life.
At present, Apple's official support account @Apple Support replied to a user's post on Twitter about the matter, saying that within 48 hours of installing the new version of the operating system, the app and some mobile phone functions need to be adjusted, and it is normal for battery life to change. You can observe for a while, and then you can contact them if you still have questions.
According to the information in the official response, most of these problems are expected to be resolved in the next few days. It's unclear how common this problem is, but if you're also affected, you can keep an eye on battery usage in the coming week.
