1. A method of controlling amplification of a signal emitted by a radio communication terminal including a power amplifier and a power supply battery, said method comprising the steps of:
detecting an output power of said amplifier and converting said output power into a first detected voltage,
modifying said first detected voltage based on an output voltage level of said power supply battery to generate a second detected voltage,
comparing said second detected voltage with a set point voltage to generate a comparison result, and
adapting an input voltage of said power amplifier based on said comparison result,
wherein said first detected voltage is increased by a correction value dependent on said output voltage of said power supply battery to generate said second detected voltage.
