I have finally found the reason for overheating and possibly also for unacceptable battery drain under 17.4.1 for my case (iPhone 13 Pro, 17.4.1). The culprit is "Require Attention for Face ID", "Attention-Aware Features" or perhaps both.


After one day of usage I can confirm that battery life is back to normal levels: about 10% drop in one hour screen-on browsing.


This means about 10 hours browsing time at modest screen brightness from a full charge, which is more or less what I was getting before "upgrading" to 17.4 (17.4.1) with my iPhone 13 Pro (now at at 92% battery health).


With "Require Attention for Face ID" and "Attention-Aware Features" ON, I get instead more than 20% drop per hour of browsing under otherwise the same conditions (connection, position, screen brightness, apps used, etc.)
