Abstract
An approach provides for limiting power adjustment in a wireless system (e.g., cellular network) to extend, for example, talk time. Parameter values specifying operating conditions of the wireless terminal are collected for power adjustment of a radio frequency (RF) amplifier within the wireless terminal. A power adjustment factor is computed based on the parameter values, wherein the power adjustment factor is used adjust limiting power of the RF amplifier.
