How to set the talk time limit of Xiaomi mobile phone?

In the dialing interface, press "Menu Key" and then press "Settings".

At present, the talk time we see is only test data, which is the same as standby time. The actual call time depends on network conditions, power consumption of mobile phones, batteries and other factors.

More accurately, the talking time of mobile phone refers to the time required to start calling and keep in touch with the mobile phone until the mobile phone automatically disconnects from contact under the premise that the battery of the mobile phone is fully charged. The longer the call time, the smaller the power consumption of the mobile phone, and the stronger the ability of the mobile phone to receive signals. Conversely, the shorter the call time, the greater the power consumption of the mobile phone, and the worse the ability of the mobile phone to receive signals.

Of course, the main factors that affect the talk time of mobile phones are battery capacity, usage environment and usage methods. For example, if the battery power is insufficient, the talk time of the mobile phone will definitely be reduced; Mobile phones talk longer outdoors than indoors, because indoor mobile phones need to consume a certain amount of electricity to penetrate walls or other obstacles.

Of course, if you turn on the phone screen and background light during the call, the call time will definitely be shorter than under standard conditions.
