AI Technical Summary
⚠Technical Problem
Devices that can receive power from both a removable battery and a USB Type-C power supply may shut down unexpectedly when the battery power is low due to unintentional cable removal, especially when the battery's remaining capacity is insufficient.
⚗Method used
An electronic device is configured to detect the connection of a USB Type-C power supply and switch power sources from the battery to the power supply, displaying warnings based on different threshold values depending on the power source, thereby reducing the risk of shutdowns.
🎯Benefits of technology
This solution effectively reduces the adverse effects of low battery power by prioritizing power from the USB Type-C supply and adjusting warning thresholds, minimizing unexpected shutdowns and data loss.

Abstract
To provide an electronic apparatus that can reduce the occurrence of a problem due to low residual quantity in a battery when connected to a power supply apparatus to receive power supply.SOLUTION: An electronic apparatus according to the present disclosure has acquisition means for acquiring information on a residual quantity in a battery that supplies power for operating an electronic apparatus, detection means for detecting a connection of a power supply apparatus that supplies power to the electronic apparatus, control means for controlling the power supply apparatus to supply power to the electronic apparatus instead of the battery when a connection of the power supply apparatus is detected, and display control means for displaying a warning on the remaining amount of power in the battery on display means when the electronic apparatus is operating on battery power and a residual quantity in a battery is below a predetermined threshold. The display control means makes the display means display a warning about the residual quantity in the battery when the connection of the power supply apparatus is detected and the residual quantity in the battery is below a second threshold that is different from the predetermined threshold.SELECTED DRAWING: Figure 1
