Determines how long the wireless IP phone (see "Type") can operate on a single battery charge in standby mode.

In standby mode, the phone is on and ready for use, including receiving calls, but none of its features are used, and power consumption is minimal. Therefore, this indicator is rather theoretical — in fact, the operating time is usually less, because even without calls, the user often has to access various features of the phone.

Time of operation of a wireless IP telephone (see "Type") on one battery charge in the talk mode.

Note that this paragraph indicates the "perfect" time — for the case when the user does not interact with any other features, except for the conversation. And since in fact this is unrealistic (you have to use at least the controls and the screen), then the actual time of continuous conversations will be less than the claimed one. Nevertheless, this indicator allows you to fairly accurately assess the battery life of the phone.
