Some users are claiming that the battery has been reduced by more than half compared to before the update, and the battery is 80% dead after 24 hours after charging, even though Safari, YouTube, Instagram, Uber, etc. have not been used for less than 2 hours.
Apple released iOS 15.4 on the 14th of this month. This OS is available for download on iPhone 6s and later models released in Fall 2015. However, the ability to unlock the iPhone while wearing a mask only applies to relatively recent models such as the iPhone 12 and 13 series. iOS 15.4 also adds a new voice to Siri, the voice assistant service, and provides over 30 new emojis.
