Last night my iPhone 7 drained from about 80% to 25% overnight. This hasn't really happened before. There is no SIM in the phone and it's mostly been lying around.
The battery health is 94% and it's regularly charged and in good shape. Background app refresh and all other privacy and battery draining settings are already set to save battery.
The only thing I did was to take some video clips (4k 30 fps, about 3 mins) and pictures last evening. The screenshot shows camera audio as consuming most battery. But the other screenshot shows some mysterious battery hog.
What's going on? Thanks in advance!
