There was some urban myth going around a few years ago about some guy who was killed while talking on his phone while it was on charge. I can't remember the details, it might have been a lightning strike or it might have been complete rubbish

A lightning strike on a landline while you're using it could easilly kill you.
One coming through the mains & a charger then through a mobile phone; it's possible. But like a whale turning into a vase of flowers, not very likely.
