7 watt hours is an insanely damaging amount! Basically a 7 watt bulb next to you for an hour, or exposure to a 70 watt bulb (that would cause third degree burns in seconds) for six minutes. Yes the peak output of a phone is less than 70 watt but you can do a lot of damage with that much energy.

I downvoted you because this is incorrect. You're ignoring the skin's ability to dissipate heat. Brief exposure to high heat does not have the same effect as extended exposure to low heat.

Please explain, how is the total energy capacity of the whole battery in any way relevant to this discussion?

Well, if you designed some custom electronics to transfer all of that energy at once, directly into your skull... Well that could be dangerous right?
