Electronic device with accessory-based transmit power control
First Claim
1. An electronic device configured to couple to an external accessory, comprising:
- an antenna;
wireless radio-frequency transceiver circuitry that transmits wireless signals at a wireless transmit power level using the antenna; and
control circuitry that receives an identifier from the accessory and that controls the wireless radio-frequency transceiver circuitry to adjust the wireless transmit power level based on the identifier and based on transmit power commands received from a wireless base station.

Abstract
An electronic device may be provided with wireless circuitry for transmitting and receiving wireless signals. Control circuitry may be used to adjust transmit power levels for the wireless signals and other settings for the wireless circuitry. The electronic device may be operated in conjunction with an external accessory. The accessory may be equipment that includes a dock connector, a case to enclose the electronic device, equipment that is coupled to the electronic device using a cable, or other external electronic equipment. An identifier may be stored in the accessory. The impact of the accessory on the wireless performance of the electronic device may be characterized and associated with the identifier. During operation of the electronic device, the electronic device may adjust transmit power levels and other settings based on the identifier of the accessory and based on sensor data, user input, and other information.
