For those who upgraded to iOS 15.4, is your iPhone powering down a little faster?

More and more people are reporting poor battery life after OTA upgrades. In severe cases, a model with a large battery like the iPhone 13 Pro Max can only last for half a day. Or the iPhone 11 will use up 80 percent of its battery in 24 hours, with the screen on for just 2 hours.
This problem is far from common, and some temporary battery drain issues after an update are sometimes common, but now the drain seems to be higher than ever.
Some users have speculated that Apple has started using the maximum 120Hz ProMotion refresh rate more frequently. That sounds plausible, but it can’t be the whole explanation, as only the iPhone 13 Pro and Pro Max have ProMotion, and those aren’t the only models affected. Hope these issues will be resolved soon.
In addition to battery issues, iOS 15.4 includes over 100 new emojis from the Emoji 14.0 set, new voice options for Siri and the ability to provide time and date information offline, support for EU digital COVID-19 immunity certificates in Apple Wallet’s vaccine card, Improvements to Safari web translation for Italian and Chinese, improvements to the Podcasts app, and more
