A few days ago, Apple started rolling out the iOS 15.4 update to all compatible iPhones. This new version of the operating system includes several important new features such as better compatibility with the DualSense controller, 37 new emojis and the possibility of installing updates with mobile data. First of all, the update allows you to unlock iPhone with Face ID even if your face is covered with a hygienic mask.
Unfortunately, it comes with the updatereduced battery life on some iPhones. According to the opinions of some users on Twitter, installing the firmware has seriously reduced the durability of their device.
iOS 15.4 is accused of draining iPhones battery: why not panic?
“Battery life on iOS 15.4 is really bad. After 24 hours I lost 80% but the screen was inactive for more than 2 hours and I only use Safari, YouTube, Instagram, Uber”, testifies to a user. Another claims “My phone charges at 95% or 97%, then when I unplug it it shows 100%, maybe 5 minutes later or after restarting it quickly discharges”.
It can be assumed that the reduction in autonomy is linked to: 120Hz display activation iPhone 13 Pros. Apple has really enabled high refresh rate in social networking apps like Twitter or Instagram. Until now, these applications were limited to 60 Hz, which consumes less energy. However, it should be noted that many older iPhone users (iPhone 11, iPhone 12…) who do not have a 120 Hz display are also affected.
It is not uncommon for the installation of an iOS update to cause a sharp decrease in the autonomy of some iPhones. Recently, every OS update has come with a series of complaints. But it isa completely normal phenomenonand it is often temporary.
Indeed, installing an update activates a number of tasks in the background. These various tasks, such as battery calibration, consume battery life. It only takes a few days for the calibration to complete and everything back to normal. Still, Apple is never slow to offer a patch to fix a potential bug.
