VoLTE testing cuts smartphone battery life by 50%

Wireless carriers future plans include VoLTE, which is passing voice traffic in addition to data over 4G LTE. Right now carriers are only testing this service and customers will not see this hit the real world until 2013 at the earliest. Recently a study was conducted by Metrico Wireless showing a significant drop in battery performance when using voice calls over 4G LTE. According to the study authored by Ardeshir Ghanbarzadeh "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." In order for carriers to transition voice service to 4G LTE they’ll have their work cut out for them trying to solve battery issues that will be a sure deal breaker for most customers. Unless the manufacturer's intend to use extended batteries larger than current factory batteries most users would run out of power midday.
