Well! Lets do the math!
iPhone 6 and 6 Plus has;
InvenSense MP67B 6-axis Gyroscope and Accelerometer Combo
iPhone 6S and 6S Plus has;
InvenSense MP67B 6-axis Gyroscope and Accelerometer Combo
iPad Pro 12.9 has;
InvenSense MP67B 6-axis Gyroscope and Accelerometer Combo
Same sensor, Same battery consumption. Its not about the battery consumption. Nobody cares battery consumption ofcourse except Apple defenders. Even Apple doesnt care battery consumption. Is that clear?
If anyone still worrying about that. Im telling again. M8 motion co-processor already always works. Except battery save feature.
MP67B specially designed for Apple. It almost same with MPU-6500. This product's Accelerometer has wake-on-motion feature. Accelerometer doesnt work fully everytime.
Accelerometer normal operating current: 450μA = 0,45 mA
Low power accelerometer mode current: 6,37μA - 17,75μA (Let's take the average) = 0,01206 mA (this one not important)
Average person checks their device 85 times a day (Lets take it 100)
Lets give a lot of time for this checks. 10 seconds.
Accelerometer normal operating time;
100*10=1000 second = 0,277777778 hours
Accelerometer operate consumption for Raise to Wake
0,45*0,277777778= 0,125 mAh
That means Accelerometer effects only;
iPhone 6's battery capacity 1810 mAh
%0,006906077348066 per day
iPhone 6 Plus's battery capacity 2915 mAh
%0,0042881646655232 per day
Gyroscope operate consumption is 3,2 mAh
Gyroscope operate consumption for Raise to Wake
3,2*0,277777778= 0,8888888896 mA
iPhone 6's battery capacity 1810 mAh
%0,049109883403315 per day
iPhone 6 Plus's battery capacity 2915 mAh
%0,030493615423671 per day
Total Raise to wake battery consumption;
0,8888888896 + 0,125 = 1,0138888896 mAh per day
iPhone 6's battery capacity 1810 mAh
%0,056015960751381 per day
iPhone 6 Plus's battery capacity 2915 mAh
%0,034781780089194 per day
Who cares %0,056015960751381 or %0,034781780089194 battery consumption per day? Nobody cares. Apple doesnt care too.
People, now Stop complaining about the battery!
