One of the important novelties of iPhone 5S is the implementation of a face named by Apple, M7. M7 is a motion co-processor that will process the data collected by the accelerometer, gyroscope and compass, eliminating the need to use the processor for calculations and reducing energy consumption. Chip M7 it constantly monitors the sensors in the iDevices, processes the data itself and then sends them to the various applications that use it, this process practically reducing the consumption of energy and resources.
The new M7 coprocessor is like a sidekick to the A7 chip. It's designed specifically to measure motion data from the accelerometer, gyroscope, and compass — a task that would normally fall to the A7 chip. But M7 is much more efficient at it. Now fitness apps that track physical activity can access that data from the M7 coprocessor without constantly engaging the A7 chip. So they require less battery power.
The M7 chip is implemented by Apple specifically for geolocation and fitness applications, they can take data about our location and position much more easily, without generating additional load for the processor. Thanks to the new hardware, applications will be able to know when we walk, run or drive a car, developers having the opportunity to implement a whole suite of new functions based on the APIs provided by Apple, but their implementation will require time .
M7 knows when you're walking, running, or even driving. For example, Maps switches from driving to walking turn-by-turn navigation if, say, you park and continue on foot. Since M7 can tell when you're in a moving vehicle, iPhone 5s won't ask you to join Wi-Fi networks you pass by. And if your phone hasn't moved for a while, like when you're asleep, M7 reduces network pinging to save your battery.
Basically, Apple tried with this M7 chip to offer a new processing unit for the data most frequently used by applications, thus reducing energy consumption and freeing the processor from additional tasks, and in the end we will have a iPhone 5S fast.
