iPhone 15 Pro overheating after iOS 26 update, even in air-conditioned rooms

My iPhone 15 Pro is overheating after the update to iOS 26. The advisor suggested waiting for the next update, but Apple released beta versions for testers. Why did they release the public version without addressing this significant issue? The advisor recommended turning off the device for a while, but even after turning it off for several minutes, I’m still facing the same problem. Moreover, since I use this as my primary mobile device, Apple should consider this issue. The same problem occurs when I’m in an air-conditioned room.
