… while spending half the day on the cell.

It’s doing something.

From the link:

Radiation from a mobile phone call can make brain regions near the device burn more energy, according to a new study.

Cellphones emit ultra-high-frequency radio waves during calls and data transfers, and some researchers have suspected this radiation — albeit inconclusively — of being linked to long-term health risks like brain cancer. The new brain-scan-based work, to be published Feb. 23 in the Journal of the American Medical Association, shows radiation emitted from a cellphone’s antenna during a call makes nearby brain tissue use 7 percent more energy.
