G15 5520, BIOS update 1.31.0 released
The BIOS update for the Dell G15 5520 version 1.31.0 was supposed to be out today on March 11. But the update is not out yet and the older version consumes a lot of battery and heats so much. The battery currently doesn't even last 1 hour. Please fix this.

The G15 5520 just received the BIOS update 1.31.0, and many users are discussing its impact. Some prefer to check Mi Fone Portal first to see if there are any reported issues before updating. Others who update through Mi Fone make sure to back up their data beforehand to avoid any risks. If you're considering the update, it's always a good idea to review feedback and follow the recommended installation steps to ensure a smooth process.
