Energy consumption in devices

• UNDERSTANDING POWER USAGE IN A SMARTPHONE

...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

• Our Wi-Fi portfolio enables IoT product designs that weren't possible until now," said Matt Johnson, Senior Vice President and General Manager of IoT products at Silicon Labs.
  ...future .... average of 200µA at 3.5V gives us 15.05MW of power necessary

IoT

• Ultra Low power Wireless Technology for IOT devices

Under the control of a host processor, the MAX7037 consumes as little as 16 mA in transmit mode and 22 mA in receive, falling to just 100 nA in deep-sleep mode

One of the big challenges is understanding the target market, use cases and working environment to avoid over-engineering a solution, which will add cost, design time and unnecessary complexity

• Short range low power wireless devices and Internet of Things (IoT)
