Its biggest highlight feature is using Face ID to unlock the phone while wearing a mask, but the new Face ID feature is only available for 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 users claim that Apple iPhone 13 Pro Max phones only last half a day. And older iPhone 11 phones had 80 percent less battery power and 2 hours of screen-on time in 24 hours.Of course, this issue is far from universal and some temporary battery issues after updates are sometimes expected. Some users have speculated that Apple has started using the ProMotion refresh rate of 120Hz max more frequently. That sounds plausible, but it may not be the full explanation, as only the iPhone 13 Pro and Pro Max have ProMotion refresh rates, and those aren't the only models affected, so hopefully those issues will be resolved soon.The iOS 15.4 update also brings more than 100 new emoji from Emoji 14.0, new voice options for Siri and the ability to provide time and date information offline, support for EU digital COVID certificates in Apple Wallet's Vaccine Card, improvements to Safari web translation with support for Italian and Chinese, improvements to the podcast app, and more.Finally,for more cell phone repair knowledge, welcome to follow us at oriwhiz.com for occasional updates on the latest information.Oriwhiz Parts is a manufacturer that specializes in the production and sale of cell phone repair screens, and also provides cell phone repair batteries and other replacement parts.
