All hairdryers do have one heat setting - a temperature that does not burn hair. I was not implying anything. Defined: a temperature to harm electronics would burn hair.

Meanwhile, air flow is not significant. Gentle air flow (ie from an air duct) or violent air flow (ie from a hurricane) does not affect an orthongonal parameter - temperature. Why is airflow from a hairdryer even mentioned? A common mistake made by those who did not learn the science; who assume more airflow means hotter.

A 'hair dryer' similar device that does burn skin is a heater for heat shrink tube. What is that device used on? Electronics. Devices too hot (dangerous) to dry hair are used in electronics manufacturing.

Hair dryer does not harm a cell phone. Mention of air flow has no significance - only possible by ignoring numbers and by not learning the underlying science.

Described is what makes drying a cell phone difficult. Hair dryer will not cause damage. But a hair dryer cannot dry where water causes failure.

Nothing was implied. Clearly stated (and not understood by classicman) is a heat setting for all hair dryers - low enough to not burn hair and skin.
