Claim Text:
1. A method for adjusting a power of a mobile phone, comprising following steps of: a. determining whether a maximum power transmission instruction from a base station is received before establishing a phone call, wherein if receiving the maximum power transmission instruction from the base state, it means a specific absorption rate (SAR) test or an antenna radiation power test is to-be performed; and if not receiving the maximum power transmission instruction from the base station, it means none of the SAR test and the antenna radiation power test is to-be performed; b. determining whether an interrupt signal emitted from a range sensor is received after it is determined that the maximum power transmission instruction from the base station is received, wherein the range sensor emits the interrupt signal when a distance between the mobile phone and a human face is within a predetermined distance range of 0 to 3 centimeters; and after it is determined that the maximum power transmission instruction from the base station is received, if receiving the interrupt signal emitted from the range sensor, it means the SAR test is to-be performed; and if not receiving the interrupt signal emitted from the range sensor, it means the antenna radiation power test is to-be performed; c. setting a maximum output power of a radio frequency power amplifier (RFPA) to be a first output power so as to perform the antenna radiation power test when it is determined that the interrupt signal is not received, and setting the maximum output power of the RFPA to be a second output power so as to perform the SAR test when it is determined that the interrupt signal is received, wherein the first output power is larger than the second output power, the first output power is 33 dBm, and the second output power is 32 dBm; and d. controlling the RFPA to output radio frequency (RF) signals with the maximum output power.
