Wireless charging for an input device

A computer-implemented system comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable storage mediums containing instructions configured to cause the one or more processors to perform operations including:
• establishing, by a base device with an input device, a wireless communication connection for bi-directional wireless communication between the base device and the input device;
• wirelessly emitting, by the base device, a continuous burst of electromagnetic (EM) power to charge the input device while the input device is on or near a surface of the base device;
• determining, by the base device, that the wireless communication connection with the input device has been disconnected;
• waiting for a threshold time period after determining that the wireless communication connection has been disconnected;
• maintaining the continuous burst of EM power during the threshold time period;
• and
• maintaining the continuous burst of EM power after the threshold time period when the base device receives an indication that the wireless communication connection with the input device has been reestablished during the threshold time period.

A non-transitory computer-program product tangibly embodied in a machine-readable non-transitory storage medium that includes instructions configured to cause one or more processors to:

• establish, by a base device with an input device, a wireless communication connection for bi-directional wireless communication between the base device and the input device;
• wirelessly emit, by the base device, a continuous burst of electromagnetic (EM) power to charge the input device while the input device is on or near a surface of the base device;
• determine, by the base device, that the wireless communication connection with the input device has been disconnected;
• wait for a threshold time period after determining that the wireless communication connection has been disconnected;
• maintain the continuous burst of EM power during the threshold time period;
• and
• maintain the continuous burst of EM power after the threshold time period when the base device receives an indication that the wireless communication connection with the input device has been reestablished during the threshold time period.
