Voice over LTE draining battery life in half

While the voice over LTE, more commonly known as VoLTE, is seen as the future of mobile phone calls, the new technology may not be well received by consumers. According to a new report from Spirent Communications, VoLTE can reduce a smartphone’s talk-time battery life in half.

The research firm came to a conclusion : “The significant difference in current drain between VoLTE and CDMA technologies for voice calling applications suggests further optimization of devices supporting VoLTE calls are needed in order to give end-users talk-time battery life expectancy levels similar to that of 3G devices” .

Interestingly enough, tests also showed that simultaneous voice and data usage on an LTE network resulted in 11% less battery drain, compared to using CDMA for voice and LTE for data.

“This is possibly attributed to the fact that only the LTE radio is in use when using VoLTE/LTE, whereas the CDMA radio and the LTE radio are in use when conducting the session in CDMA/LTE”.
