Personally, I perceived it as a matter of good engineering: your phone shouldn't spend its energy to heat your ear.

- salynchnew 3y agoInteresting! There might be other unintended issues from transmitting heat, I suppose? Even from transmitting heat to the phone's components itself or other items that are nearby, e.g. laptops: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5219578/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5219578/.

This power is a maximum that will only be used if the reception is bad. In the wavie scene (people who are paranoid about radio waves controlling them) shielding those devices is a typical approach — this is also where the meme of the tinfoil hat comes from. Ironically that shielding makes your cellphone operate with the maximum transmission power at all times.
