Portable electronic device with emergency mode for low battery usage and method for using the same

A portable electronic device includes a battery reserve feature for emergency use, reserving a portion of battery power when a predefined threshold is reached. A battery detector monitors the real-time battery level, sending data to a host controller that compares it to the threshold stored in non-transitory memory. Upon reaching the threshold, a masking module signals a depleted battery state to the operating system, disabling regular functions while a display shows a “no power” message, concealing the reserve. User interaction, such as pressing a designated button, activates an emergency subsystem to perform operations like initiating emergency calls, sending GPS coordinates, capturing screenshots, or activating alarms, using the reserved power. The threshold may be dynamically adjusted based on environmental or location-based factors.
