3 gru 2020 · The new iPhone 12 models move between 4G and 5G to conserve battery power. When 5G is needed -- like for high-def video streaming -- it'll automatically tap into that network.
AirTag is embedded with the Apple-designed U1 chip using Ultra-Wideband technology, facilitating accurate location finding for iPhone 11 and iPhone 12 users. This innovative technology can more accurately determine the distance and direction of a lost AirTag when it is in range.
Wyświetlacz iPhone’a 12 ma zaokrąglone rogi, które podkreślają jego opływowe kształty, a zarazem wpisują się w kształt regularnego prostokąta. Przyjmując, że powierzchnia ekranu jest prostokątem, jego przekątna wynosi 6,06 cala (faktyczny obszar wyświetlania jest mniejszy).
