We only measured audio streaming over LTE but the results give indications of what the results would be for video streaming cases as well. The results in Figure 7 show that traffic shaping can save some energy even when cDRX is disabled. However, when shaping the traffic through the proxy, we can save almost up to 60% of energy in the best case when cDRX is enabled. Moreover, we note that enabling cDRX does not help at all when streaming directly from the server.
