Abstract: Various embodiments in the disclosure provide methods implemented by a processor executing on a mobile communication device to dynamically determining whether the power saved by powering down the RF chain between the end of the last reception activities and the beginning of the next reception activities will exceed the power expended to reinitialize the RF chain's components and registers for the next reception activities. Based on this determination, the device processor may configure the RF chain either to power down fully, as in conventional implementations, or to enter a low-power mode in which power is maintained to the power rails supplying the memory registers storing RF communication data, thereby avoiding the power surge of restarting the registers and part of the power drain associated with writing the communication data back into the registers. In some embodiments, the mobile communication device may be a multi-SIM device.
