Worked on the Battery-Emulator repository to enhance reliability and stability of the Battery Page, specifically addressing a core panic issue that occurred when multiple batteries were present on the advanced page. Applied a targeted C++ patch that limited the display of detailed battery information to only the main battery, reducing the risk of system panics and improving user experience in battery-rich scenarios. The solution was carefully aligned with the existing embedded systems architecture and followed established testing practices. This focused bug fix improved maintainability by minimizing regression risk and provided a clear path for future enhancements in the web-based interface.
