Why do the LEDs indicators on the IQOS holder and pocket charger flash yellow, white and white

Generally speaking, the LED on the IQOS holder and the battery status LED on the pocket charger flash yellow, flash white, and light up in white, indicating that the IQOS is in the state of charging, resetting, etc., or whether it is within the operating temperature range. These are normal phenomena and not machine malfunctions.
