In this way, the power amplifiers used by the component to be lower. Overall, power consumption becomes more efficient by the Tools to improve smartphone's battery power .
Power sales due to the best-selling bank smartphone battery life is very low.
Average for normal use, battery life is only one day, whether it's a smartphone Android, BlackBerry, or iPhone, just the same. Even if the use of smartphones in the normal rechargeable (charge) the battery can be two times a day.
Various studies have been and continue to be done to extend battery life. But what is interesting is the finding of two researchers at MIT (Massachusetts Institute of Technology), which can save up to 50% smartphone battery that will power the smartphone battery life on average two days to once refilled.
According to the two researchers, battery waste occurs in the amplifier system in the smartphone. Energy waste here even reach 65%. Amplifier function to convert electrical power into radio signals. Amplifier is used mainly when sending data.
Amplifier consists of transistors that require electrical power when in standby mode and output mode (at strengthening and sending digital data pulses). Efficiency can be achieved by lowering the power level as low as possible during standby mode.
But. sudden increase of low power standby mode to high power mode when the output mode is likely to be damaging signal. As a result, today's high power retained even in standby mode. This is where the power dissipation occurs.
The more data that is sent by a smartphone higher power dissipation. The higher speed of data communication, getting a much needed standby power than the signal power. That's why smartphones became hot when sending large data.
At the time of data reception actually also be a waste, because the process is busy smartphone sends a confirmation to the sender of the received data is complete or error. Data delivery confirmation lead amplifiers are also active.
Two MIT researchers, Joel Dawson and David Perreault, saying that they have overcome this problem by creating a new amplifier designs. Both professors in the field of electrical engineering has also started Eta Devices companies to develop and produce these findings.
The new amplifier design has a function similar to the electronic gearbox. This component will select one of the different voltage delivered to the transistor, which makes the low power consumption. This is done as many as 20 million times per second.
