Another problem has been revealed in the latest version of Apple’s operating system. It is a fast consumption of the power reserve. Will this lag go away on its own?
As some users have reported, the latest version of Apple’s operating system has a problem with the battery life of the phone. With the upgrade to iOS 15.4, some people have noted a halving of battery capacity. Moreover, some also mention that the battery drops, for example, by 5 percent within 10 minutes, while others say their phone “lasts” only half a day.
It is important to note that this may not be a bug per se, as two years ago Adrian Kingsley-Hughes explained in a text from ZDNet that many background processes, such as indexing and recalibrating the battery, were going on during the installation of the new version of the operating system. This process can take quite a bit of time, so recalibration can have a big impact on some users. So you will have to be patient and wait for a while.
