ARM Architecture - Power Modes

How can combining power modes with sensor management improve battery life in wearable devices?

ABy disabling sensors when not needed and switching to low power mode to reduce energy use

BBy keeping all sensors active and running at full power constantly

CBy increasing sensor sensitivity to use more battery

DBy ignoring power modes and focusing only on sensor data

Step-by-Step Solution

Solution:

Step 1: Understand sensor and power mode roles in battery saving
Disabling unused sensors and using low power mode reduces energy consumption.
Step 2: Identify the best combined approach
By disabling sensors when not needed and switching to low power mode to reduce energy use correctly combines sensor management with power modes for battery saving.
Final Answer:
By disabling sensors when not needed and switching to low power mode to reduce energy use -> Option A
Quick Check:
Sensor management + power modes = Better battery life [OK]

Quick Trick: Turn off unused sensors and use low power mode [OK]
