Mobile phones-Do you feel they still emit too much radiation when using them or charging them or just them being on?

They emit a tiny amount of microwave radiation. If you ever happened to be on a boat with a radar on it, you've been exposed to far greater amounts of that type of radiation. Or, if you ever walked near any place with a tower, or if you entered any building with a wi-fi network. Your terminal is limited by its battery to the amount of power it can emit.

What causes health concerns anyway is ionizing radiation, and even in that case, you're still daily exposed to it, unless maybe you go around only at night and covered by tinfoil, or better, a thick layer of lead. And guess what, lead is toxic too, lol

Every single wireless, non RFID device receives and emits radio waves. The frequencies used are not capable of causing damage at the cellular level. In addition, cell phones use very little energy.

What may be of concern, is very heavily packed cell towers.

No. They only emit radiation (VHF radio) when transmitting; and that at very tiny power. The electromagnetic field around the charger is negligible.
