This document discusses measuring the energy consumption of an AndroidThings application running on a Raspberry Pi. An Arduino with an INA219 shunt is used to measure the power drawn by the Raspberry Pi running an AndroidThings app that sends weather data via SMS. The results showed the app running for 8 hours idle, 2 hours while sending SMS messages, and 20 minutes to send 10,000 SMS messages. Examining the Android system UI process revealed it used 3 times as much energy as other processes due to software events. Improving how events are handled could increase battery life by 42 minutes. The document concludes that IoT energy consumption will increase due to managed data transfer and that efficient IoT design is important for environmental and
![Premature Optimization ?
There is no doubt that the grail of
efficiency leads to abuse. Programmers
waste enormous amounts of time thinking
about, or worrying about, the speed of
noncritical parts of their programs [...]We
should forget about small efficiencies, say
about 97% of the time: premature
optimization is the root of all evil.Yet we
should not pass up our opportunities in
that critical 3%.

- 2. Olivier Philippot CTO, Greenspector #Eco-design #greenIT #Energy for software
- 3. Why do you need to measure energy ? Sofware is eating the world and it needs energy!
- 4. Transporting bits now uses 50% more energy than world aviation, and will likely use twice as much by 2030. Mark P. Mills - CEO, Digital Power Group - www.tech-pundit.com
- 6. How they measure energy ? Before Now
- 7. How we measure energy ? We dont.
- 8. Not so true
- 11. Use case : Send weather information by SMS Raspberry PI OS : AndroidThings (make the Apps meetThings !) SMS Service : CiscoTropoPimoroni Rainbow Hat Weather Station
- 12. Under test : AndroidThings on Raspberry
- 13. Arduino to manage measurement
- 14. Arduino + INA219 Shunt to measure
- 15. The measurement infrastructure Arduino Shunt Raspberry USB Power For Raspberry Arduino to PC For data Network
- 16. Arduino + INA219 Shunt to measure
- 17. The code : Sending SMS from IoT withTropo
- 18. Energy Idle SMS
- 19. The result on 10 000 mAh battery -8 hours -2 hours -20 mn
- 20. Is it the Hardware or Softwares fault?
- 21. Google Android System UI
- 22. Energy x3
- 23. Event in System UI Software events Hardware events Android events management Algorithms Graphics
- 24. Events are like butterfly effect
- 25. Improvement 1 event managed every 20 events + 42 mn
- 26. Premature Optimization ? There is no doubt that the grail of efficiency leads to abuse. Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs [...]We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil.Yet we should not pass up our opportunities in that critical 3%.

- 27. Conclusion IoT energy consumption will bloat not because of code but due to managed data! An autonomous IoT is not so simple Measure, Measure and Measure Efficient IoT (and cloud) is good for earth and for users!
Editor's Notes
- #3: Im Olivier Philippot and Im CTO of Greenspector. You can easily hear that Im not american but a little frenchy. And Im really happy to be here ! What do I do ? Providing energy knowledge and efficiency for developers. That is why I created greenspector a tool suite for energy measurement and green IT !
- #4: Sofware is eating the world and it needs energy !
- #6: Mobility is everywhere. And there is a real impact on the autonomy, which we can see when we need to plug our smartphone every night. With IoT, it would be the same : try and change the battery on your hundred devices every year and your wallet will feel it !
