Microsoft has just announced a new ROG Xbox Ally feature that should help boost battery life while maintaining great game performance. Named 'Default Game Profiles,' the feature applies optimal power and FPS limit settings to supported games, saving you from having to optimize your settings yourself. Already supporting 40 games, including Call of Duty: Black Ops 7, Doom: The Dark Ages, and Minecraft, the setting will be applied by default when you're running your handheld on battery, making it a completely seamless experience. The update is now available for the Xbox Ally X and Xbox Ally, but we'd expect it to eventually roll out to the other Windows options, such as those you'll find on our best gaming handheld guide, though Microsoft hasn't confirmed this yet.Read the full story on PCGamesN: Microsoft's new Xbox Ally update brings big battery life boost in 40 games, including Hollow Knight Silksong and Minecraft
