Apple is closing what is probably the most important security gap in its WebKit browser engine. Since not only Safari uses the engine, browsers such as Firefox and Chrome were also affected in the past. When surfing, the browsers unintentionally communicated the surfing behavior and the account IDs of users. So if you want to ensure the security of your iPhone, the installation is a mandatory download. Apple was in such a hurry with the update that the beta for iOS 15.3 was only released a few days ago. An unusually short period of time between beta and release.
This is how you download the update
The update to iOS 15.3 should arrive on your phone as a notification on January 28th. If you tap on this, you will find a download button. If you don’t see a notification and want to search for the download manually, that’s also possible. To do this, go to your iPhone’s settings, then tap on General and select “Software Update”.

On the iPhone 13 mini, Apple canceled the update because I had less than 50 percent battery capacity left. So pay attention to it or connect your iPhone to the socket when downloading.
