Beijing time, March 15th morning news: According to foreign media reports, a recent comparative test of battery performance when using VoLTE services on the first and second generation VoLTE smartphones on the US mobile operator MetroPCS network found that the new LG Spirit 4G When a mobile phone is performing a VoLTE call, the power consumption is reduced by 35% compared to the previous generation product.
In addition, the experiment also found that the combined effect of improved power consumption and battery capacity increased the battery life of VoLTE calls by 122%, which is almost the same as when using previous terminals for CDMA calls.
Spirent CommunicaTIons said the company conducted experiments in Dallas to measure and quantify the impact on battery life when talking on CDMA and 4G LTE networks.
The company has collected samples of power consumption and power consumption in multiple locations in this market, including CDMA and VoLTE calls, and multi-service CDMA / LTE and VoLTE / LTE voice and data simultaneous calls. Spirent also tested the use of the Skype OTT Android app for VoIP calls on LTE data networks.
The following are some main findings:
· The results show that compared to the first generation mobile phone, the current VoLTE mobile phone has a 35% reduction in power consumption when making VoLTE calls, and an 18% reduction in power consumption when making CDMA calls;
· When using Skype OTT VoIP application to make a call on the LTE network, the power consumption dropped by about 1/3;
In terms of using CDMA calls, the battery life of the latest VoLTE terminal is better than the previous generation terminal.
Nigel Wright, vice president of Spirent Communications ’wireless division, said:“ We conducted the second round of VoLTE battery performance testing to see if recent technological advances have helped reduce power consumption and improve VoLTE call capabilities. "
