Techniques for wireless charging in a system, method, and apparatus are described herein. An apparatus for charging at a wireless power receiver may include logic. The logic is configured to supply voltage received at the wireless power receiver at a first power level to a battery that is initially fully discharged, wherein the power of the first power level is received during a predefined interval of a fully discharged battery protocol. The logic is to monitor a second power level available at the battery, and initiate a wireless handshake with a wireless power transmitter inductively coupled to the wireless power receiver indicating configurations of the wireless power receiver upon detection of the second power level meeting or exceeding a predefined threshold.
