Cell phone signal jammers consume a lot of battery power for most cell phones. Because when the mobile phone jammer is turned on, the signal between the mobile phone and the base station will be blocked. In fact, it will be interfered and normal communication with the base station will not be formed. Well, many mobile phones have this function: when there is no signal, the mobile phone has to work very hard to search for a signal, which causes it to consume a lot more power than in the normal standby state!
suggestion:
If you are within the interference range of the cell phone signal jammer for a long time, turn off the mobile phone (there will be no signal even if it is not turned off) to reduce the consumption of the mobile phone battery. Wait until you leave the interference range of the mobile phone signal jammer and then turn on the mobile phone again.
If you are within the interference range of the phone signal jammer for a short period of time, the consumption of the mobile phone battery can be ignored.
