System features

Freeform
Freeform is a whiteboard app that lets users collaborate together in real time. The whiteboard is an "Infinite" space where users can draw, import files, facetime, message, all fluently in sync. AirDrop 
In iOS 16.2, the default setting is "Contacts Only,” and the "Everyone" setting was changed to "Everyone for 10 Minutes,” which reverts to "Contacts Only" after 10 minutes "to prevent unwanted requests to receive content.” This was enabled in iOS 16.1.1 for iPhones in China. Lock screen
The lock screen's appearance is customizable and it can host Widgets. The font and text color for the date and time can be customized to 8 presets and color effects can be applied to the entire lock screen. The date is now above the time and a small widget can be added next to the date. Other widgets can be added and arranged horizontally on the third row, below the time. Multiple lock screens can be set up. The live wallpapers have been removed because of the new tap and hold gesture that would allow users to customize their lockscreen. The lock screen also supports landscape mode, arranging elements horizontally instead of vertically when the phone orientation is horizontal. When listening to podcasts and music, tapping the album cover will cause the cover to appear full-sized in the center of the lock screen with a color-matched background. Title change
For the first time in Chinese interface, iOS 16 rewrites the title of the user from "您" and "您的" to the less formal "你" and "你的", and some third-party applications still keep the title "您" and "您的". When using the system for the first time, in the agreement dialogue on the same screen, two different appellations of "您" and "你" can be seen to address the user at the same time. There is no information to explain the reason for the change of title. Improved focus mode
Different lock screens can be set up based on the active focus. Focus filters allow apps to show different content based on active focus. For example, Safari will only show work-related tabs if the user enabled 'Work focus'. Likewise, the Mail app will only show email messages from an allowed list of work contacts. The user can create lists of apps and contacts to be silenced and lists of those to be allowed. Notifications
Notifications roll up from below the lock screen, rather than above. It is possible to show notifications in three different styles: count, stack or list. Notifications can be grouped together with two fingers to reduce them to a counter.

The status bar can display the battery percentage on iPhones with Face ID, so the user doesn't need to pull-down the Control Center to see it. Improved dictation
During text dictation, the keyboard is always present and allows the user to switch from speech to manual typing and vice versa without interruptions. It is also possible to insert emojis through dictation. Auto-Punctuation automatically inserts a period when there is a pause in the dictation. Improved Live Text

A new accessibility setting allows the user to prevent phone calls from being ended by locking the phone. Wi-Fi network improvements
Previously saved Wi-Fi networks are shown which can be edited, deleted or selected to view the network password after authentication via Face ID or Touch ID. Prior to this change, users’ only option for removing previously connected-to networks was to tap ‘forget this network’ from within the settings app which could only be done if connected to that network. Users also had (and still have) the ability to wipe all previously known networks from their iOS devices by choosing ‘erase network settings’ from Settings–>General–>Transfer or reset iPhone(at bottom)–>Reset–>Reset Network Settings. The latter option is frequently advised to those seeking to fix a multitude of both Wi-Fi and cellular network issues arising on users iOS devices. Cellular network improvements

Lockdown mode
Lockdown mode is a special mode that, when activated, raises the security to the highest possible level by restricting some features of the OS, apps and web platform, in order to protect users from the rarest and most sophisticated attacks. Unlike many other security features, lockdown mode is regarded as an “extreme, optional” mode that is not intended to be activated by the majority of users. Rather, it is designed as a defense against advanced malware and mercenary spyware, such as clickless exploits or zero-click attacks, which are often hyper-targeted toward influential individuals such as journalists, diplomats, politicians, activists, lawyers, and high-profile business people. It is possible to disable the Lockdown mode on specific websites and apps by acting from the Safari’s Website Settings and the Lockdown mode's Web Browsing setting. Passkeys
Passkeys allows the user to authenticate to services that implement WebAuthn across their devices without using passwords. Passkeys are generated by the phone and permission is granted via Face ID or Touch ID. Safety Check

Applications and websites now require permission to copy from the clipboard. Private Access Tokens
Private Access Tokens are a new technology that replaces CAPTCHAs and helps in identifying HTTP requests from legitimate devices and people without compromising their identity or personal information. Brand Indicators for Message Identification
Brand Indicators for Message Identification (BIMI) helps users to easily verify authenticated emails sent by brands by displaying the brand's logo alongside the email's header. Known issues
On iOS 16.0, a bug causes Image Capture to fail to import photos on computers running macOS Mojave and older. This was fixed in the iOS 16.1 update. Users have reported worse battery life, higher standby drain, and heating issues. Supported devices
iOS 16 requires an iPhone with an A11 Bionic SoC or newer which means support is dropped for devices with an A9 or A10 Fusion SoC. This is the first version of iOS to drop support for an iPhone SE. However, iPhones with an A11 and A12 Bionic SoC have limited support, while iPhones with an A13 Bionic SoC or newer have full support. The cutoff for the iPhone 7 and 7 Plus has been criticized due to the iPad 5th, 6th and 7th generations supporting iPadOS 16 despite having similar or even weaker hardware. iPhone 8 & 8 Plus
