It seems likely that an electrical fault in a few phones is causing voltage to flow to all the green sub-pixels in a line.
Scroll down the Battery Status screen, and inside you'll see the ADC reading of your phone together with its voltage, network connectivity, and signal strength.
Any leftover power can be used to charge a mobile phone or other low-voltage device.
In April 2009 the European Parliament adopted a report urging the European Commission to set limits on how close mobile phone masts, antennas, high-voltage power lines, and other electromagnetic field (EMF transmitting devices can be to neighborhoods, schools, and health care facilities.
DO NOT buy one that produces a voltage higher than the phone battery can handle, (for example: 6V), which may damage the battery.
"While peak power is interesting, the best way to calculate the amount of energy that can be delivered to your phone is by measuring the change in voltage of AMPY's internal battery before and after generating energy.
Our extras tend to be things like phone and camera chargers, electric outlet and voltage adaptors, earphones, spare glasses, a small pair of binoculars and the like... although one of us does tempt airline fate by packing a tiny hotel sewing kit in an obscure backpack pocket.
This is just a safety precaution, as it will disconnect the (very low voltage) power flowing from the phone company line.
He sued Con Edison, which, it turned out, had installed a high-voltage vault beneath the pay phone at Hudson and Morton Streets.
Participants with electromagnetic hypersensitivity (EHS) who attributed their symptoms to appliances and/or high voltage transmission lines or mobile phones were excluded using the EHS screening tool developed by Eltiti et al. [ 16].
