IT House March 19 news, according to GSMArena reported that earlier this week, Apple began to launch iOS 15.4 official version, along with iPadOS 15.4, watchOS 8.5, macOS Monterey 12.3, tvOS 15.4 and HomePod software 15.4 updates. Its biggest highlight feature is wearing a mask and using Face ID to unlock your phone. However, the new Face ID feature is only available for the iPhone 13 and iPhone 12 series.
In addition to some new features and bug fixes in iOS 15.4, more and more people are reporting poor battery life after OTA. Some netizens said that Apple's iPhone 13 Pro Max mobile phone can only maintain a half-day battery life. Older iPhone 11 phones have an 80% reduction in battery power and a 2-hour screen on time in 24 hours.
Of course, this problem is far from a common phenomenon, and some temporary battery problems after the update are sometimes expected. Some users speculate that Apple has started using proMotion refresh rates up to 120Hz more frequently. That sounds plausible, but that might not be the whole explanation, as only the iPhone 13 Pro and Pro Max have ProMotion refresh rates, and these aren't the only models affected. It is hoped that these issues will be resolved as soon as possible.
The iOS 15.4 release update also includes more than 100 new emojis from Emoji 14.0, new voice options for Siri and the ability to deliver time and date information offline, support for EU digital COVID certificates in Apple Wallet's vaccine cards, Safari web translation improvements that support Italian and Chinese, improvements to the podcast app, and more.
