Recent ios 15.4 update caused battery drain for some users


This week, Apple began distributing ios 15.4, iPadOS 15.4, watchOS 8.5, MacOS Monterey 12.3, tvOS 15.4, and HomePod Software 15.4. With this update, you’ll be able to unlock your phone with a mask on using Face ID. You can read more about it here.

For iPhone users with an Apple Watch, iOS 14.5 offered Face ID with a mask as a pleasant gesture for those without one. However, the faster and less secure new Face ID only works with the iPhone 13 and iPhone 12 models. Let’s say it’s a half success.

Because not everyone can afford to purchase an Apple Watch, the latest upgrade is critical. When iOS 15.4 was released, iPhone owners had to re-enter their Face ID passwords since the third face scan took longer to finish.


For Face ID to validate a user’s identity even if the user is wearing a mask, it will now concentrate on the area surrounding their eyes, which has unique traits that may be used to identify the individual.

Many users are suffering battery drain following the iOS 15.4 OTA, and this isn’t the first time this has happened. Things like the iPhone 13 Pro Max’s half-day battery life. With two hours of screen on time, an earlier iPhone 11 loses 80 percent of its battery power in only 24 hours. In addition to these and other reports.

Aside from that, the problem isn’t universal, and it’s possible to anticipate some battery issues following an upgrade. And although iOS 15.4 doesn’t seem to be a substantial update, it contains a remarkable 39 bug fixes. Even yet, the reported battery drain rates raise an eyebrow or two. Some people believe that Apple is utilising the maximum 120Hz ProMotion refresh rate more often.


It’s possible, but it can’t be the whole storey since only the iPhone 13 Pro and Pro Max feature ProMotion, and these aren’t the only devices afflicted. It would be great if the difficulties could be rectified quickly!

However, iOS 15.4 also includes more than 100 new emojis from the Emoji 14.0 set, a new voice option for Siri, offline time and date information for Siri, EU Digital COVID Certificate support for vaccination cards in Apple Wallet, enhancements to Safari web page translations, and more.
