Talktime

Talktime or talk time is a term used in the mobile device industry to describe the duration of constant use supported by a device's single fully charged battery while the device is performing a cellular call.

Talktime is highly dependent on the cellular network environment, such as the distance to the closest cell tower, as the device will increase transmission power when the signal strength wanes. Moving fast, such as being in a vehicle in motion, negatively affects talktime.

Mobile device manufacturers measure talktime in controlled conditions, but there is no standard for cell tower distance that all measuring must be bound by. In real-life scenarios,
