Electric shock from mobile phone battery (without power adapter)?
Hello, last night I was lying in bed and then picked up my cell phone to check the time. There were chocolate stains on the side of the case where the on/off buttons were. Then I thought I felt a tingling sensation in my hand. Can something like that give you an electric shock, or is my mind acting up?
No! If the phone is connected to the power supply via cable, you can sometimes feel a slight creep if you e.g. with the finger back easily over metal parts. This, however, is absolutely harmless, has what to do with capacitive coupling (e.g., by suppression capacitors always in power supplies).
My battery now discharges very quickly, after half an hour of moderate use 5% have been consumed, can it be that power failures start from battery and because n defect is present?
Also no, the battery has a much too low voltage to be dangerous with a max. 4.2V. Even if you touch the poles of the battery directly with your fingers, you wouldn’t notice anything.
A cell phone has 4 volts. You can’t remember that.
A power strike through the phone is practically excluded. The battery is charged with a very low voltage. .
What can lead to a tingling: a static charging of clothing by friction. Sometimes you can see small flashes when you pull out a sweater. These are voltages of several hundred volts, which are discharged there. – but you can remember that.
Psyche was crazy.
