iOS 16: battery drain quickly, iPhone slow & more

There are also some minor bugs, but they don’t affect usability:

  • The iPhone 14 Pro Max comes with iOS 16 in the photo app. Images are displayed incorrectly when viewed in landscape mode and zoomed in on. The problem will be fixed with a new iOS 16 update that is already available.
  • In the new iOS version, Apple has also introduced an “always on” function for the display of the iPhone 14 Pro Max. However, this works differently than you are used to from Android devices. As such, the screen here isn’t completely dimmed to display the time and other “AoD” information. Instead, the display screen remains visible in the background. This is not a bug, but the way Apple intended it to work.
  • In iOS 16, Apple adds a photo widget that you can fill with your own pictures. However, the widget cannot be set up immediately after the update because the iPhone first has to analyze all available images. So direct the widget to a later point in time enter if it still doesn’t work.
  • Immediately after the update, iOS still has to arrange and sort things in the background. It may therefore be that the iPhone shortly after the update running slowly and, for example, keystrokes are registered late. The problem should correct itself after a short time.
  • The increased background activity immediately after the update also leads to that the battery discharges very quickly shortly after installing iOS 16. However, the shorter battery life should also regulate itself as soon as iOS 16 is fully set up.
  • Some iPhone 14 users complain that AirDrop is not working for them. It is currently sometimes not possible to send files from an iPhone 14 to a contact. Instead, the “Wait” display remains permanently in the image. So far, no other iPhones are known to have the problem. The problem should be fixed with an upcoming update.
  • With iOS 16, the percentage display for the battery should actually return to the display. The function is there but not on all iPhones. So you can not turn on the percentage display on the iPhone XR, iPhone 11, iPhone 12 mini and iPhone 13 mini. This isn’t a bug, it’s intended by Apple.
  • Apple has revised the weather app for iOS 16. The data now comes from the provider “Dark Sky”. According to some reports fit the temperature data for Germany not in the prediction. In addition, some unnecessary weather warnings will be triggered.

Camera bug on the iPhone 14 Pro

Instead, the camera problem with the iPhone 14 Pro should be fixed with the update to iOS 16.0.2 (source:
