Problems solved by technology
While these improvements appear seamless when implemented by the average consumer, the transfer of information across the network can be complex
For example, because wireless signals are essentially electromagnetic fields oscillating at high frequencies, they are susceptible to interference from devices that generate electromagnetic waves
Interference can degrade signal quality and affect the user's experience when making phone calls or browsing the Internet
Many components and algorithms are available to improve handling of interference, but often many times they lack the ability to resolve signal quality issues

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.
Description
technical field [0001] The present disclosure generally relates to improving the signal quality of wireless communications occurring on computing devices. More specifically, embodiments herein relate to limiting the activity of accessory devices coupled to a computing device based on signal quality of wireless communications to reduce electromagnetic interference. Background technique [0002] Wireless communication capabilities of various types of computing devices continue to improve as device components become more advanced. Improvements including the coverage of wireless networks and the speed of individual processors have created a world where it is possible to transmit information to anyone on the planet at any time. While these improvements appear seamless when performed by the average consumer, the transmission of information across the network can be complex. For example, because wireless signals are essentially electromagnetic fields that oscillate at high freque...
