If you’ve ever lost yourself in a game on a handheld device, you know just how immersive and convenient that experience can be. Devices like the newly-announced Asus ROG Xbox Ally are redefining portable play - bringing full-fledged PC gaming to your hands, whether you're on the move or lounging on the couch.

For developers, this shift introduces new challenges and opportunities. From optimizing performance on compact hardware to designing for smaller screens and varied input methods, building for handhelds requires a thoughtful approach. In this article, we’ll explore key best practices to help you craft exceptional gaming experiences for handheld devices. For more information, be sure to head over to the Xbox Handheld Gaming Developer Resource Hub.

Native Controller Support

While today’s handheld gaming PCs run full Windows environments, delivering a great experience on these devices requires more than just PC compatibility. What sets a good handheld game apart from a great one is how naturally it plays in your hands.

These devices demand the kind of seamless, intuitive input experience players expect from consoles. That’s why native controller support isn’t just a feature - it’s foundational.

At Xbox, we’ve developed the GameInput API, a next-generation input framework designed to unify and simplify device support. By abstracting the input stack, it provides a consistent interface for a wide range of input devices-from gamepads and adaptive controllers to steering wheels - across all platforms.

By adopting GameInput, developers can:

  • Write their input logic once and deploy it everywhere.
  • Avoid duplicating input logic for different devices.
  • Ensure compatibility with emerging handhelds and cloud-streamed environments.
  • Future-proof their games for evolving hardware ecosystems.

Battery Friendly Performance

When developing for consoles and PCs, performance tuning often centers around maximizing CPU, GPU, and memory efficiency to push graphical fidelity. But when it comes to handheld gaming devices, there’s another critical dimension to consider: power consumption.

These devices are battery-powered, and every watt counts. At Xbox, our research shows that the GPU is typically the biggest power draw - making it the first place to look when optimizing for energy efficiency.

Using telemetry from our own studio titles, we’ve validated several strategies that can significantly extend battery life without compromising gameplay quality:

  • Clamp the Frame Rate with VSync
    Enabling Vertical Sync (VSync) limits the maximum frame rate, reducing the workload on the GPU and other components. This is one of the most effective ways to cut power usage on handhelds.
  • Use AI-Powered Upscaling
    Implementing a final upscale pass with AI-based upscaling can maintain visual fidelity while lowering the native rendering resolution-delivering crisp visuals with less GPU strain.
  • Pause or Reduce Frame Rate When Idle
    Players often walk away from their devices mid-session. Detecting idle states and reducing frame rates-or pausing entirely - can yield meaningful energy savings.
  • Design Handheld-Specific Game Modes
    Consider offering a “handheld mode” that adjusts internal resolution, reduces effects, or simplifies rendering in non-critical scenes like menus or lobbies. You could include presets such as Low Power, Default and Full Power (when plugged in). This helps align your game’s power profile with the device’s capabilities.

Optimizing for energy efficiency isn’t just about battery life - it’s about respecting the player’s experience. At Xbox, we are passionate about the environmental impact of gaming. If your title explores sustainability themes, we’d love to collaborate. You can also request a free Certification Sustainability Power Report to get targeted insights into your game’s energy profile.

Allow offline play

One of the biggest advantages of handheld gaming devices is their mobility. Whether you're commuting, traveling, or just relaxing on the couch, these devices let you take your games anywhere. But with that freedom comes a challenge: network connectivity isn’t always guaranteed.

That’s why supporting offline play is essential. Players should be able to launch your game and access their save data-even without an internet connection.

To make this seamless, we recommend using the XGameSaveFiles API. It’s a flexible, developer-friendly solution that supports both cloud and local save systems. With XGameSaveFiles, players can:

  • Save and load progress locally when offline
  • Sync their data to the cloud when back online
  • Enjoy a consistent experience across devices

This approach gives developers the best of both worlds: flexibility in implementation and reliability for players. Whether your game is single-player or supports cross-device progression, XGameSaveFiles ensures that players stay connected to their progress-even when they’re not connected to the internet.

Accessibility in Handheld Gaming Devices

While ensuring that your game runs smoothly, supports native controls and doesn’t use too much power are all important, it is also essential to ensure that your game is accessible and adaptable to the unique constraints of handheld play.

One of the most important considerations is text readability. On handheld screens, players typically sit 30–40 cm away. At that distance, small fonts can quickly become a barrier. Prioritize legible text sizes that don’t require squinting or straining - tiny text is a fast track to player frustration.

Some suggestions for text readability:

  • If the screen is 1280 x 720, the pixel height of the text should be at least 9 pixels – we recommend the height to be 12 pixels or more.
  • If the screen is 1980 x 1080, the pixel height of the text should be at least 14 pixels – we recommend the height to be 16 pixels or more.

Beyond text, context-aware iconography is key. If a player is using a keyboard, show keyboard prompts. If they switch to a controller, update the UI to reflect controller buttons. This dynamic feedback helps players stay immersed and in control, no matter how they choose to play.

Devices like the Asus ROG Ally offer a mix of input methods - thumbsticks, buttons, and touchscreens. Your game should not only support these inputs but also allow players to customize controls to suit their preferences and needs. For example, you can change the default input to expect a gamepad and pop up a virtual keyboard when text input is expected.

Beyond that, embracing native touch input can significantly enhance usability—especially for UI-heavy interactions like navigating menus, selecting items on a map, or using pinch-to-zoom gestures. These touch-friendly features don’t just improve the handheld experience—they also translate well to cloud-streamed scenarios, where players may be using phones or tablets with touchscreens.

If your in-game UI is designed around mouse input, consider making it more accessible by allowing players to directly tap icons in the HUD or interact with UI elements via touch. These small adjustments can make a big difference in how intuitive and enjoyable your game feels on handheld devices.

By designing with accessibility in mind, you’re not just improving usability - you’re expanding your audience and making handheld gaming more welcoming for everyone. For more details on Xbox accessibility guidelines, please head over to this link to learn more.

Play Anywhere: Seamless Gaming Across Devices

Today’s gamers are no longer tied to a single screen. In fact, more than half of players regularly switch between devices - console, PC, and handheld - expecting their experience to follow them wherever they go. That’s where Xbox Play Anywhere (XPA) comes in.

XPA empowers players with cross-progression and cross-entitlement, allowing them to pick up right where they left off-no matter the device. Whether they’re unlocking achievements on console, customizing characters on PC, or grinding through levels on a handheld, their progress, purchases, friends list, and even leaderboard rankings stay perfectly in sync.

With XPA, players enjoy:

  • A unified game library across devices
  • Cloud saves that travel with them
  • Shared entitlements for in-game purchases and add-ons
  • Seamless continuity of achievements and progress

This kind of seamless experience is quickly becoming the norm for modern players. When implemented thoughtfully, it helps keep players engaged, connected, and eager to return.
