Mobile device energy usage is likely to increase, particularly with onset of 5G (+ future iterations) and in some cases mobile devices are likely to replace mains powered products.  Hence the objective of this task are to:

• Examine the energy used by mobile devices (connected and otherwise).
• Investigate policy options to improve their energy efficiency (including the power supply, the battery charging equipment and the device itself, as well as the impact of various battery chemistries).
• Assess the similarities and differences between mobile device energy efficiency policies around the world.
• Identify pathways towards international harmonization of policies for mobile devices.
