Why some people died in their bath after smartphone dropped into water ?

<< < (4/7) > >>

KL27x:
Even considering the possibility of shoddy chargers, that had nothing to do with the majority of the deaths.

E.g., one girl thought to have touched a frayed mains extension cord while in the bath. One young man thought to have set his CHARGER (not the phone) on his chest while laying in the bath; i.e. he set the extension cord and charger plug directly on himself. Both peeps plugged the extension cord into a non-GFI outlet.

If the problem was shoddy chargers, wouldn't they be destroying phones, regardless of the vicinity to a bathtub?

The case I know about, the girl had her charger plugged into a damaged extension cord.

Mobile phones are completely floating, electrically.  Mains voltages would cause the entire device to attain a potential with respect to the world around it, but internally, there is no such risk.

But add a path to ground and things change.

Thank the Media for sensationalising such stories.  They take the attention grabbing subjects of "phones" and "injury/death" in order to get an audience - especially for headlines - and don't get too excited about being more detailed until later in the article, if at all.

Even if there was an isolation fault, a phone dropped into the tub would make the current seek the ground, it won't take a detour through your body --- unless you grab it and it's metal, which is what I suspect happened in a lot of cases.
