SmartHertz

SmartHertz gives you direct control over your Android device's screen refresh rate, letting you optimize performance and battery life with precision. Adjust the refresh rate based on what you're doing—gaming, browsing, or everyday tasks—and extend your device's battery life by reducing unnecessary power draw when you don't need high refresh rates.

The app intelligently detects the refresh rate of apps you're using and applies similar settings to comparable applications automatically. This means you won't need to manually configure each app one by one. When battery runs low, the refresh rate adjusts across your device to preserve power, giving you longer usage time on a single charge.

Control is at your fingertips with a straightforward interface that makes it easy to fine-tune your device's performance. Lower refresh rates reduce GPU and display power consumption, which directly translates to longer battery runtime. Higher refresh rates deliver smoother scrolling and gameplay when you need responsiveness. This app puts that balance entirely in your hands.

Note that SmartHertz requires superuser permissions to function, as it needs deep access to your device's display settings. Additionally, some apps enforce their own refresh rate limits, which may prevent the app from achieving the exact rates you set—the app can only control the screen's refresh rate, not override app-level restrictions. Despite these constraints, having manual control over this critical power setting gives you advantages unavailable in standard Android settings.

If you want granular control over your device's behavior and are comfortable with advanced tweaking, SmartHertz delivers the tools you need. Android 11 or higher is required to use this app.
