SmartHertz

If you're someone who, as soon as you get a new Android device, wants to have all the permissions to be able to control it to the max, SmartHertz is the perfect app for you.

SmartHertz is a tool that lets you control the refresh rate of your device's screen. You'll be able to adjust it according to what you're doing, so it's a useful way to optimize your battery. The refresh rate of your device can negatively affect the battery, so having control of it can extend the life of your Android device.

This tool detects the refresh rate of the app you're using and assigns it to other similar apps. This way, you won't have to go one by one. Of course, when you're low on battery, the rate is lowered across your device.

However, in order to take advantage of these benefits, you'll need to have superuser permissions on your device. You should also be aware that many apps limit the FPS, so even if you use SmartHertz, it's possible that the refresh rate will stay low, since this tool can only control the rate of the screen.

Even so, SmartHertz offers many advantages, and it's an essential app if you like to have full control over your device.
