...**A processor** running at full steam will consume 3,000 mW at its peak 
...to be about 1,000 mW for a standard **5-in HD display**, and rising to 1,500 mW for the quad HD screens.
... boosting its **own transmission power**, hence more power consumption. How much power: what is an average power of 1,000 – 1,500 mW could double or more

...future ....  average of 200µA at 3.5V gives us **15.05MW of power necessary**
