The maximum power output of a mobile phone is ~200 mW (0.2 watt) and that happens only for short periods (miliseconds) at the time. That is not enough energy to even penetrate the skin, much less the skull. The amount of energy the article talks about is 1000x that amount and for an extended amount of time. A lot of travelers experience headache after flying. Blood pressure changes, blocked sinuses, CO2 accumulation, change in sleep cycles etc. can all contribute. Source: degree in technical medicine
