The iPhone 13 Mini is the smallest smartphone available from Apple at this time and that size is the primary reason I got it.
Since I come to iOS from Android, the following list can have some basic operations that are unusual for Android users.
Power off: Press and hold one of the volume buttons and the side buttons until a slider is displayed to power off.
Take a screenshot: Press and release the volume up and side button simultaneously.
Customize Control Center: The Device Controls you get by swiping down from the top in Android is called Control Center in iOS. Go to Settings -> Control Center to customize what is displayed in it. Sadly, the Settings app itself cannot be added to the Control Center.
Customize lock screen: Press and hold on lock screen until it asks to swipe to unlock. Do not swipe up from bottom, instead press and hold on lock screen again. Unlock now and you get the lock screen customization UI.
Open camera: Swipe left on lock screen to open the camera app.
Disable Live Photos: This feature is enabled by default and it captures a few seconds of video before-after a photo is captured. To turn it off, open the Camera app and disable its icon at the top-right corner.
Switch to JPEG/H.264: By default, photos and videos are saved to Apple’s own HEIF/HEVC formats. To save to JPEG/H.264 go to Settings -> Camera -> Formats and choose Most Compatible.
Import Google contacts: Go to Settings -> Contacts -> Accounts and add your Google account. Only after this will your Google contacts appear in the iPhone Contacts app.
[Go back:] Reaching to the left-arrow icon at the top-left corner is a real pain. The alternative (which isn’t obvious and I had to look it up) is swipe the left side of the phone to the right. This alternative does not always work though, for example in a photos app where you are swiping left-right through the photos already.
