That depends on your humidity. As I already said, if you’re in a desert that’s normally dry enough…
If you’re not in a desert, though, you’ll have to dry the desiccant for it to have an actually significant effect. Though that’s true regardless of which desiccant.
Within the phone, general relative humidity is FAR more important than airflow.
Yea, I agree in the general sense, although you will always have something akin to countries so long as the entire world isn’t literally communist. Thus making the distinction rather pointless.
