MIUI Developer Options: Full Guide

MIUI developer options are a hidden settings menu on Xiaomi, Redmi, and POCO phones that unlocks advanced features like USB debugging, animation speed controls, and background process limits. To access them, you open Settings, tap About Phone, and tap the MIUI version seven times. This guide explains what each useful option does, which ones are safe to change, and how to avoid common mistakes.

What Are MIUI Developer Options?

Developer options are a standard part of Android, and MIUI (Xiaomi’s custom Android skin) includes them alongside its own extra settings. The menu is designed for app developers to test software, but everyday users often turn to it for tweaks like faster animations, better gaming performance, or forcing apps to stay in memory. MIUI adds a few of its own options on top of the standard Android list, such as MIUI optimization and memory optimization levels, which can affect battery life and app behavior.

Because MIUI aggressively manages background apps by default, developer options are frequently used to stop apps from being killed too quickly. However, changing the wrong setting can cause instability, so it helps to know what each toggle actually does before touching it.

How to Enable Developer Options on MIUI

The process is the same across MIUI 12, 13, 14, and HyperOS (the newer name for MIUI on some devices). Follow these steps:

Open Settings on your phone.
Scroll down and tap About Phone (sometimes called “About device”).
Find MIUI Version or HyperOS Version.
Tap that version number 7 times in quick succession. You may see a countdown or a “You are now a developer” toast message.
Go back to Settings, scroll down, and you will see Developer Options (sometimes under “Additional settings”).

If the menu does not appear, make sure you are tapping the version text itself, not the “About phone” header. On some devices, you may need to enter your lock screen PIN after the seventh tap.

Key Options and What They Do

Not every option in the developer menu is useful for a normal user. Here are the ones that matter most, grouped by purpose:

USB debugging – Allows a computer to communicate with your phone for file transfers, ADB commands, or flashing firmware. Required for most PC tools.
Window animation scale, Transition animation scale, Animator duration scale – Set all three to 0.5x or off to make the interface feel snappier. This does not increase actual processing speed, but it reduces the time animations take.
Background process limit – Limits how many apps can run in the background. “At most 2 processes” can save RAM but may break notifications or background downloads.
Don’t keep activities – Destroys every app as soon as you leave it. This makes multitasking nearly impossible and is only useful for debugging.
Force GPU rendering – Forces apps to use the GPU for 2D drawing. On modern phones this is usually unnecessary and can increase battery drain.
MIUI optimization – A MIUI-specific toggle that enables Xiaomi’s custom battery and memory management. Turning it off can cause notification problems and is not recommended unless you are testing an app.

Most other options (like “Select USB configuration” or “Simulate secondary displays”) are for developers and should be left alone.

How to Choose the Right Settings

If you are a regular user, the safest tweaks are the three animation scales. Set them all to 0.5x – this gives a noticeable speed boost without sacrificing usability. If you want the UI to feel instant, set them to off, but some users find that abrupt transitions feel less polished.

For better multitasking, you can increase the background process limit from “Standard” to “At most 3 processes” or higher. However, MIUI’s own battery saver may still kill apps regardless of this setting. To keep a specific app alive, use the “Lock” feature in the recent apps view instead – it is more reliable than any developer option.

If you are a developer or a power user who wants to use ADB commands, enable USB debugging and USB debugging (Security settings) if you need to change system settings via a computer. The security option is hidden by default on some MIUI versions – you must be logged into a Mi account and have a SIM card inserted to enable it.

Common Problems and Fixes

Many users enable developer options and then encounter issues. Here are the most frequent ones:

“Developer options are not available for this user” – This happens when you are using a secondary user profile or a work profile. Switch to the primary user (the one set up first) to access the menu.
USB debugging not working – On MIUI, you often need to enable both USB debugging and USB debugging (Security settings). Also, make sure the phone is unlocked and the “Allow USB debugging” prompt is accepted on the phone screen.
Phone becomes slow after changing settings – Reset all developer options to their defaults. You can do this by tapping the three-dot menu in the top-right corner of the developer options screen and selecting “Reset to default values.”
Notifications stop appearing – This is usually caused by turning off MIUI optimization or setting a low background process limit. Turn MIUI optimization back on and set the limit to “Standard.”

If a setting causes a boot loop (rare but possible with “Force GPU rendering” or “Don’t keep activities”), reboot into safe mode (press and hold the power button, then long-press “Power off”) and revert the change.

MIUI Developer Options vs. Stock Android

MIUI’s developer options are largely the same as stock Android’s, but Xiaomi adds a few extras. The most notable difference is MIUI optimization, which does not exist on stock Android. This toggle controls Xiaomi’s aggressive app management, notification handling, and battery optimization. On stock Android, apps are managed by the system automatically, and there is no single switch to disable it.

Another difference is the memory optimization level (Low, Medium, High, or “Off”) that appears on some MIUI devices. This setting adjusts how quickly the system reclaims RAM from background apps. On stock Android, this is handled by the kernel and not exposed to users.

Finally, MIUI hides the USB debugging (Security settings) option behind a Mi account and SIM card requirement, which stock Android does not do. This is a security measure to prevent unauthorized ADB access.

Is It Safe to Use Developer Options?

For the most part, yes. The animation scale and USB debugging options are safe and widely used. However, some options can cause real problems:

Disabling MIUI optimization can break notifications, background sync, and battery life. It is not recommended for daily use.
Setting background process limit to 0 will make your phone unusable for multitasking and may cause apps to crash.
Force GPU rendering can increase battery drain and heat on some devices, especially with older GPUs.
Changing “Select USB configuration” to something other than “Charging” can cause the phone to connect to computers in unexpected ways, but it is not dangerous.

If you stick to the animation scales and USB debugging, you are unlikely to encounter any issues. Always make a note of what you change so you can revert it if something goes wrong.

Alternatives to Developer Options

If you want the benefits of developer options without the risk, consider these alternatives:

For faster animations: Use the “Reduce animations” toggle in Accessibility settings (Settings → Additional settings → Accessibility → Remove animations). This does the same thing as setting animation scales to off.
For keeping apps alive: Use the “Lock” button in the recent apps view (swipe up, then long-press the app card and tap the padlock). This prevents MIUI from killing the app.
For USB file transfers: You do not need developer options. Just plug in the phone and choose “File transfer” from the USB notification.
For advanced tweaks: Use ADB commands from a computer, but you still need USB debugging enabled – there is no way around that.

If you are trying to improve gaming performance, developer options will not help much. Instead, use the built-in “Game Turbo” feature (in the Security app) or close background apps manually.

Frequently Asked Questions

Why can’t I see developer options after tapping MIUI version 7 times?

Make sure you are tapping the MIUI Version text itself, not the “About Phone” heading. On some devices, you may need to enter your lock screen PIN after the seventh tap. If it still does not appear, restart the phone and try again.

Does enabling developer options void my warranty?

No. Simply enabling the menu does not void your warranty. However, if you use it to unlock the bootloader or root the phone, that can void the warranty depending on your region and Xiaomi’s policy. Changing developer options themselves is not a warranty issue.

What is the best animation scale setting for MIUI?

Most users find 0.5x to be the best balance between speed and visual polish. Setting it to “off” makes the UI feel instant but can look jarring. You can also set it to 0.5x for window and transition, and “off” for animator duration, which is a common combo.

How do I reset developer options to default?

Open Developer Options, tap the three-dot menu in the top-right corner, and select Reset to default values. This will revert every toggle to its original state without affecting your personal data.

Is it safe to turn off MIUI optimization?

It is safe in the sense that it won’t damage your phone, but it will likely cause notification delays, background app closures, and worse battery life. It is intended for developers to test app behavior, not for daily use. Keep it on unless you have a specific reason to disable it.

Can developer options improve battery life?

Not directly. Limiting background processes or turning off MIUI optimization may reduce battery drain in the short term, but it often breaks notifications and sync, which can cause apps to work harder when you open them. The best battery improvements come from normal settings like battery saver mode and screen brightness.
