Operators hoping to engage in widespread deployment of voice over LTE in order to gain spectral efficiencies in their because one vendor's recent tests showed that VoLTE calls can slash a device's talk-time battery life by half.
The study comparing device battery life for calls placed over an LTE network vs. calls placed over a CDMA network was conducted on an unnamed U.S.
operator's network in two major markets using a smartphone capable of supporting both CDMA and VoLTE voice calling. "The device's estimated battery life was reduced by 50 percent or about 252 minutes of talk time when voice calls were placed over the LTE network, compared to voice calls placed over the CDMA network," says the study author.
