The owner is resting, so is the telephone?
An unusual problem with the iPhone 15 Pro Max has been identified in the United States: it turns out that the device can spontaneously turn off at night for several hours. If suddenly in the morning your iPhone asks you to enter a password, but Face ID does not work, it means that it was most likely turned off for some time.
Unexpected problem with iPhone 15 Pro Max: the smartphone turns off at night for several hours
The problem has already been well described on the American forum Reddit, as more than just isolated cases have been recorded. The fact that the iPhone 15 Pro Max was completely turned off overnight is evidenced by a dip in the battery consumption graph.
There is no clear explanation yet why this happens. The strange behavior of the smartphone is associated with the recent iOS 17.0.3 update, which eliminated the overheating of the iPhone 15 Pro and iPhone 15 Pro Max in several popular applications. This is supported by the fact that spontaneous shutdowns at night were also recorded by owners of the iPhone 15 Pro, iPhone 12 Pro, iPhone 14 Pro Max, iPhone 13 mini, and other Apple devices.
