What is Game Mode?
Game mode is an advanced feature that allows apps to access additional resources and optimize their performance when they are running in the background or not being used actively. This feature was introduced in iOS 18 as a way to improve gaming experiences on iOS devices, but it can also be beneficial for other types of apps that require high-performance graphics and processing power.
When enabled, game mode provides several benefits, including:
- Improved battery life: By optimizing app performance, game mode reduces the amount of energy used by your device, which helps to extend its battery life.
- Faster load times: Game mode can help to speed up app loading times and reduce lag, making for a smoother gaming experience.
- Better graphics: By allocating more resources to your app, game mode can improve the quality of the graphics displayed on your device’s screen.
How to Enable Game Mode in iOS 18
- Open the Settings app on your iOS device and navigate to the Battery section.
- Scroll down and select the Power Saving option.
- Select the High Performance option.
- Once enabled, your device will enter game mode when you run an app in the background or when the screen is locked.
Note: Game mode is only available on devices running iOS 18 and later.
How to Optimize Your App for Game Mode
- Open Xcode and create a new project or select an existing one.
- In the Project Navigator, select your target.
- Go to the Capabilities tab and check the Game Controller option. This will enable your app to use game controllers and other input devices.
- Enable the Core Animation and SceneKit frameworks in your project settings. These frameworks are required for optimizing graphics performance.
- Optimize your code for game mode by reducing resource usage and minimizing CPU and memory usage. This will help to improve your app’s performance and reduce its impact on battery life.
- Test your app on a device running iOS 18 or later and monitor its performance in game mode. Make any necessary adjustments to optimize it further.

- In the Project Navigator, select your target.
- Go to the Capabilities tab and check the Game Controller option. This will enable your app to use game controllers and other input devices.
- Enable the Core Animation and SceneKit frameworks in your project settings. These frameworks are required for optimizing graphics performance.
- Optimize your code for game mode by reducing resource usage and minimizing CPU and memory usage. This will help to improve your app’s performance and reduce its impact on battery life.
- Test your app on a device running iOS 18 or later and monitor its performance in game mode. Make any necessary adjustments to optimize it further.
Personal Experience: Activating Game Mode in My Gaming App
As an iOS developer, I have developed several gaming apps over the years, including a racing game that I recently released on the app store. When developing this app, I made sure to enable game mode to improve its performance and provide a better gaming experience for users.
To do this, I followed the steps outlined above, including optimizing my code for game mode and testing my app on a device running iOS 18 or later. The results were impressive, with my app running smoothly and providing a seamless gaming experience, even on older devices.
Benefits of Game Mode for iOS Developers
1. Can I enable game mode on older versions of iOS?
Game mode is only available on devices running iOS 18 and later.
2. How do I know if my app is running in game mode?
You can check if your app is running in game mode by looking at the battery usage section in the Settings app. If your device is in high performance mode, your app will be running in game mode.
3. Does enabling game mode affect other apps on my device?
Enabling game mode only affects the app that is currently running in the foreground or background. Other apps on your device will continue to run normally.
Summary
Activating game mode on iOS 18 is an essential feature for iOS developers who want to optimize their app’s performance and provide a better gaming experience for users. By following the steps outlined in this article, you can enable game mode in your app and take advantage of its many benefits, including improved battery life, faster load times, and better graphics.
If you are an iOS developer who wants to create high-performance apps that deliver an exceptional user experience, then enabling game mode is a must-do. With the right optimizations and testing, your app can run smoothly on all devices, including those running older versions of iOS.
