Crystal temperature determination method and device, terminal and computer readable storage medium

The embodiment of the invention discloses a crystal temperature determination method and device, a terminal and a computer readable storage medium. The method is applied to the terminal, the terminal comprises a temperature detection circuit and a crystal, the crystal is not internally provided with a thermosensitive element, the temperature detection circuit comprises the thermosensitive element, and the temperature detection circuit is used for determining the temperature of the thermosensitive element; the method comprises the following steps: determining a temperature curve of the crystal; determining a first temperature measurement function of the crystal according to a printed circuit board (PCB) layout relationship between the thermosensitive element and the crystal; determining a temperature offset; determining a temperature hysteresis amount; correcting the first temperature measurement function according to the temperature offset and the temperature hysteresis to obtain a second temperature measurem
