What is what does iphone is findable mean?

"Findable" on an iPhone refers to the device's ability to be located and tracked using built-in features such as Find My iPhone. This feature uses the device's built-in GPS and internet connection to pinpoint its location on a map and help the user locate it if it is lost or stolen. It also allows the user to remotely lock the device, play a sound to help locate it, or erase all data on the device to protect personal information. Findable iPhones can also be located even if they are turned off or in Airplane Mode, as long as they have a charged battery.
