SIGNAL QUALITY DEPENDENT THROTTLING OF DEVICES FOR REDUCING ELECTROMAGNETIC INTERFERENCE
First Claim
1. A method for maintaining at least a threshold quality of service (QOS) for a wireless communication conducted by wireless circuitry in a mobile device, wherein the mobile device is operatively coupled to a charging device comprising a circuit capable of generating electromagnetic interference (EMI) that adversely affects a QOS of the wireless communication, the method comprising:
- at the mobile device;
determining the QOS for the wireless communication conducted by the wireless circuitry; and
sending a throttling signal to the circuit of the charging device when the QOS is less than the threshold QOS, wherein the throttling signal causes the circuit to reduce an amount of EMI generated.

Abstract
This disclosure relates to systems, methods, and apparatus for limiting or throttling an activity of an accessory device communicatively coupled to a computing device. The activity of the accessory device is limited or throttled in order to reduce electromagnetic interference and improve signal quality of a wireless communication in which the computing device is participating. In some embodiments, a decision to throttle can be based on battery charge level of the computing device. For example, in some embodiments, the accessory device is an accessory battery charger configured to provide power to the computing device when a power outlet is not immediately available. If the signal quality of a phone call from the computing device is diminished or the user is in an area of low signal coverage, the accessory battery charger can be limited or throttled in order to prevent interference between the accessory battery charger and computing device.
