Abstract

Techniques are described herein for inferring a status of a primary battery for an electronic device in a wireless power delivery environment. In some embodiments, the status of the primary battery can be inferred, without any feedback regarding a status of the primary battery, based on a wireless charging profile of the primary battery and power usage characteristics that are monitored. In some embodiments, the wireless power transmission system utilizes the information inferred about a particular wireless device'"'"'s primary battery to control or allocate how much wireless power is allocated to a particular wireless power receiver client embedded and/or otherwise associated with the wireless device.
