iOS 16.3 brings a decisive increase in security: Apple publishes a major update for the iPhone

The most convenient and fastest way to update iPhone to iOS 16.3 is through the device itself.

1. Open the “Settings” app on your iPhone and select the “General” menu item.
2. Now tap on “Software Update” to make the iPhone check for existing updates.
3. If a new version is available, click the “Download and Install” button below.
4. When the update is downloaded, you will then receive a message that your iPhone will restart in a few seconds. It may now take some time for the installation to complete. The fact that the loading bar and the Apple logo appear several times is completely normal.

Alternatively and if there are problems with the update on the device, the iPhone can be updated on the PC or Mac.
