Don't sit in your tub while using cellphone (plugged in)
>Lovington, New Mexico
I guarantee the wiring in the house is to blame. Open up that outlet. No GFI, no proper ground, borrowed common from other circuits and reversed polarity. I found all of the above in an outlet in my bathroom that was three inches from a metal faucet hooked to all metal pipes. The electrician and/or the last person to inspect the place should be charged with murder.
I think the part where it was PLUGGED INTO THE WALL was relevant.
The cell phone probably didn't electrocute her.
Teen killed by wireless IoT toaster.
Was making toast in the bathtub.
Wireless toaster was plugged into wall.
Actual quote from the article:
"Coe was a basketball player and number one char with her tuba in the bad at school."
Thanks CBS. She really is number one char. But no need to call her bad at it, that's just mean.
>[human] killed by IoT [device].
I think we'll see more of these. This was part of the plot of Stross' SF novel "Rule 34".

I would think a properly designed wall-wart supply wouldn't provide enough voltage to be a problem. The plumbing is connected to ground, so if her soaking wet hand held the cord -- say 5 volt USB charger plug -- 1.5 amps available, but it depends on her resistance soaking wet.
If her resistance was 500 ohms, 5v/500 == .010 amps, or 10 mA.
Typical quotes are that it takes 50 mA through the heart to stop it. So something's wrong with this picture.
Still, really, don't sit in the tub while using your cellphone. At all. And if you must, make SURE it's not plugged in.
The flash drive controller will have a charge pump that produces 30V, which is needed to write to the flash cells.
There can be other things as well that are above 1.8, 3.3 and 5V in the phone.
But yeah 5VDC would be difficult to attribute to a fatality.
5VDC is also not going to be associated with burn marks.
She had burn marks on her hand and is dead.
So some part of it that is >5VDC was likely involved.
It's actually pretty interesting. Sounds like they aren't bothering to do a proper investigation.
A phone battery has enough energy to do a good deal of damage to a human.
3000 mAh, or 180 Ampere during an second.

True, but it's still the current.
You'd have to work really hard to short a battery through your chest. And if the current doesn't pass through the heart, it won't kill you.
On the other hand, an improperly designed charger, with a 'common ground' tied to the AC neutral, with a 'reversed voltage' outlet putting 'hot' to what should have been neutral (or even the charger plugged in 'upside down' whatever polarity THAT is) -- it COULD have had the 'hot' wire down the charging line to the tub.
VERY poorly designed charger.

same thing happened in London last December
I thought the domestic power supply was less deadly in the US than in Europe
I recently read a more detailed description of the situation. Apparently there was an AC extension cord involved too.
I've had really short USB charging cables -- like 12" long -- to plug into an AC to USB adapter. If she had one of those, the AC cord could have fallen into the tub. That would do it.
115 V is 1/2 as deadly as 220 V, yes. But there's some scenarios that are VERY hard to survive. "Soaking wet in a well grounded tub" is one of those.
