The hot swap feature allows uninterrupted device operation by maintaining Wi-Fi/WAN connectivity and memory persistence during battery replacement. This feature uses a backup super capacitor to ensure seamless transitions.
Replacing the Main Battery using the hot swap feature allows the device to maintain Wi-Fi/WAN connectivity and memory persistence while replacing the depleted battery with a fully charged battery. When the battery is removed, the backup super capacitor immediately takes over to sustain the system, including Wi-Fi/WAN connectivity (covering voice, data, and the current state of applications) for up to 30 seconds.
After this 30-second window, the device enters emergency (critical) suspend mode to conserve energy. In this state, the memory is preserved (allowing the device to resume rather than reboot) for up to 60 seconds. If the battery is not replaced within 60 seconds, the memory persistence may be exhausted, and the device will reboot after the battery is charged and installed. It is important to note that the persistence durations of 30 seconds for Wi-Fi/WAN connectivity and 60 seconds for memory are maximum values. These durations can be reduced based on application usage, network conditions, and the device's currently used hardware features.
