How to enable hidden developer options on Android
Before you start tweaking any advanced settings, it's essential to know how to unlock the dedicated developer menu, where most of these hidden settings are located. The process is simple and secure if you follow these steps:
- Access the app Settings from your Android mobile.
- Go to About of the phone, Software Information o System settings (the name may vary depending on the manufacturer).
- Look for the section Build Number o MIUI version on Xiaomi phones, and press 7 times in a row that option.
- You will see a message indicating that the Developer options are now available. Go back to the Settings menu and scroll down until you see the new section Developer Options.
Attention: While these options are very useful, only change the settings you understand and always make a note of your changes so you can revert them if something doesn't work as expected.
Optimize animation speed: faster and smoother mobile
One of the most effective tricks to make your mobile feel much faster and more agile It reduces the duration of animations. While it doesn't increase actual processor power, it does speed up the perception of speed, making opening apps and navigating menus instantaneous.
- Sign in Developer Options.
- Look for the section Drawing. Here you'll see three key options: Window animation scale, Transition Animation Scale y Animator duration scale.
- Set each one to 0.5x to make them twice as fast, or set to “None” if you want to remove them altogether and have an ultra-fast (albeit less visually appealing) experience.
Advantages: The phone responds more responsively, apps open faster, and the system consumes less graphics resources. Additionally, reducing the load on the GPU can also achieve a small improvement in battery life.
If your phone is old or you notice lag in the transitions, reducing the animations will be one of the most notable changes along with cleaning up background apps.
Background App Control: Improved Battery Life and Performance
Many apps remain active and running without your knowledge, consuming RAM, processor, and draining your battery. Android allows you to limit or automatically close background apps, optimizing the speed and autonomy of your device.
- Opens Developer Options and locate the section Applications.
- Active Do not keep activities if you want apps to close completely when you exit them. This frees up memory and resources, but be careful because Some apps, such as banking apps, may need to remain open for notifications or confirmations..
- If you prefer more control, use the option Limit background processes and choose between "None," "Maximum 1/2/3/4 processes," or "Standard limit." Adjusting the limit to your needs helps you avoid missing important notifications.
Extra tip: From the same developer menu you can access Running services, where you'll see in real time which apps are using memory and resources. If you identify any that are consuming too much, you can stop them immediately and diagnose problematic apps.

Power consumption is a constant concern, but Android gives you access to little-known tools to keep it under control:
- En Developer Options, look for the section Background Check (Background check), where you can see and restrict Apps that use battery unnecessarily in the background. Disable apps that you don't need to be active all the time.
- Disable Always-on mobile data If you use Wi-Fi most of the time, this prevents your phone from keeping the mobile data connection running unnecessarily, which translates into lower power consumption.
- Active WiFi scanning limitation so that the mobile phone searches for networks less often when not necessary, further reducing energy consumption.
