The Cupertino firm for its part have greatly improved the batteries for both the iPhone 6 and iPhone 6 Plus, making the power source bigger but thinner to keep the svelte profile of both iDevices. But bigger and thinner doesn’t necessarily translate to longer battery life so how does Apple maximize the juice to its premier mobile handsets?
A recent tear down of the new iPhones were done by certain quarters and they discovered something peculiar about the new iPhones: they have two accelerometers.
This discovery lead to an exhaustive research as to why Apple would include two such components with the same functionality in a single iPhone and the curious geeks where amazed how ingenious the engineers at Apple really are. Apple chose to put these two components with the same job to extend the iPhones’ battery life.
They found out that the first accelerometer was made by InvenSense and it’s a six-axis accelerometer chip which is great for gaming and other functions that need that extra inertial sensing prowess. The InvenSense Chip was the best choice for this but because of the advance feature of the component; it sucks more power from the power source when it is being used. To compensate for this, Apple added another three-axis accelerometer, this time made by Bosch, which uses less power (130 microamperes) when compared to the InvenSense chip (3.4 milliamperes). The Bosch chip also has a faster start up time than the InvenSense and because of this; it handles all the normal accelerometer jobs thus saving on battery life. When the device senses a greater need for accelerometer function, the InvenSense chip takes over the Bosch chip to handle the heavier task at hand.
The researchers added that the InvenSense chip could have been enough to handle all the accelerometer-related job needed by the new iPhones but by adding the second Bosch Chip, Apple was able to address the users’ concern about quickly draining their iPhones with daily use.
