How to Tell the Difference Between Condensation Build-Up and Cartridge Leakage

How to distinguish between condensation build-up and cartridge leakage?

We can distinguish between condensation build-up and cartridge leakage in the following simpler ways:

Sound of vaporization: During the heating process of vaporization, a "gurgling" sound indicates condensation build-up;
Liquid color: Wipe with a tissue, the e-liquid at the connection between the cartridge and the device is light yellow, while the color of the condensation liquid is dark brown;
Location: The accumulation of condensation generally occurs at the mouthpiece and the connection between the cartridge and the device, while leakage usually occurs at the bottom of the cartridge and around the sides of the cartridge.

How to resolve issues caused by condensation?

Handling condensation falls under device maintenance and can be resolved in the following ways:
Wipe the connection between the "device" and the "cartridge" with a tissue (while confirming whether it is condensation build-up);
Shake the device with the mouthpiece facing down to expel the accumulated condensation;
