This genius hack just showed you what you can do with your phone's battery!
The hack that turns your phone into a phone seems to be spoken for a while.
A close monitoring of the power flowing through the battery in a study conducted by #UT #Texas, the Hebrew University and Technion partnership revealed that different functions led to different power consumption. In this way, for example, in what application you write, "previous and next actions" such as phone calls can be detected. Power consumption of components such as CPU, GPU, screen and RAM can be monitored to determine which web sites have been visited and which keys are being pressed.
Such an attack is an enormous gold mine for the attacker, but it is difficult to say that it is difficult to attack. First, the attacker must physically access the phone and add a microcontroller who can read the power fluctuations on it.
