subject: Extend Your Cell Phone Battery Life: An Often Overlooked Method [print this page] A lot of you probably already know that cell phones use a lot of power when searching for signal, but what a lot of you may not know is that a cell phone with 4 or 5 bars will actually use much less power than an identical phone showing only 1 or 2 bars. This is because the formula that determines how many bars are displayed on your phone is also used to calibrate and set the transmit power of the phone. Take the game of football for example: when a team has to punt, the punter, regardless of field position, aims to punt the ball as close to the goal line as possible while keeping the ball in-bounds. Based on the distance, the punter will adjust the strength of his kick to put the ball where it needs to be, no more, no less. Cell phones work in the same manner - they are constantly updating their transmit power based on their signal strength and distance from the closest tower. Too little power and the signal will be indistinguishable from electrical noise when it reaches the tower. Too much power is just a waste of energy. With a cell phone signal booster amplifying both the incoming and outgoing signals, your phone can adjust itself to use a lower transmit power, thus increasing battery life. Additionally, if you are one of the thousands of people who get little or no cell service inside your home but have decent coverage outside your home, a cell phone signal booster will keep your phone from having to search for signal, thus increasing battery life.
