ASUS has issued a BIOS update for the ROG Ally that should help resolve multiple usability issues, most of them being fairly minor issues, but they're all quality of life improvements nonetheless. To start with, ASUS has made optimisations to the performance mode with the Ally plugged in to a power source, although the company didn't explain exactly what this means. Another minor improvement allows the "Memory Assigned to GPU" setting to be kept when updating to a new BIOS version, a setting that used to get reset prior to this BIOS release.

Another minor quality of life update is the ability to reduce the backlight to 10 nits now, down from the previous 25 nits, which should make it more comfortable to use the ROG Ally in dark rooms. Finally and possibly the most important part of this update is the ability to charge at 30 W from 65 W or higher rated USB-PD chargers. What ASUS has done here is improvements to the USB-PD "handshake" to make sure that the ROG Ally gets the right power from the power adapter. This was apparently not working as intended previously and the ROG Ally would charge at a slower rate. It should be noted that not all chargers will provide enough power to the ROG Ally, especially if other devices are charging at the same time. ASUS points out that if the battery is draining when the Ally is plugged in, a different charger should be used.
