Abstract: A control circuit configured to conserve battery in a mobile device is described. The control circuit upon receiving an input signal from an input sensor sends a suspend signal to the power management integrated circuit (PMIC), which may turn off power in the rest of device and keep the processor and PMIC powered on, thereby transitioning the mobile device into a suspend mode. After a predetermined period of time, the mobile device saves all processes running on the processor and registry content of the memory in a non-volatile memory on the device and shuts off the PMIC and the processor to transition into a hibernate mode. The input sensor and control circuit which receive power directly from the battery management can turn on the PMIC and the processor upon receiving an awake signal from the input sensor, thereby transitioning the device back to an awake mode.
