延长电池使用时间 当网络信号不存在或极其微弱时,关闭手机。 尽量选择在网络信号强的地方通话。 选用省电模式,GSM标准具有一项先进功能,即大部分手机上都具备了“DTX”非连续性发射省电模式,为了省电,当机主不发声时,电话暂时降低发射电波的功率。试验发现,DTX省电模式最多可以延长通话时间的30％～50％,具体情况视手机型号而定。目前北京地区的GSM网已设定并应用了DTX省电模式。
Extend battery life Turn off your phone when network signals do not exist or are extremely weak. Try to choose where the signal is strong in the network. Select power-saving mode, GSM standard has an advanced function, that is, most mobile phones have a “DTX” discontinuous transmission power saving mode, in order to save electricity, when the main speaker does not sound, the phone temporarily reduce the power of the radio waves . The test found that, DTX power saving mode can extend the talk time of up to 30% to 50%, depending on the phone model may be. At present, GSM network in Beijing has set and applied DTX power saving mode.
