How to optimize MIUI Xiaomi smartphones: 15 proven ways

Branded shell MIUI Xiaomi is known for its rich functionality, but users often face brakes, fast battery discharge and intrusive advertising. POCO This article will help you turn your smartphone into a fast and energy efficient device, without root rights, custom firmware or loss of functionality.

We will break down three levels of optimization: basic (for beginners), advanced (for power users), and extreme (for enthusiasts willing to sacrifice some features for performance). MIUI 14/15 (including HyperOS for new models and suitable for Redmi Note devices 10 Xiaomi 14 Particular attention is paid to problems that the manufacturer deliberately does not fix in global firmware - for example, background activity of system applications or forced data caching.

Before proceeding, check the version of your firmware in Settings. → The phone. → Version. MIUI. If you have HyperOS (starting with Xiaomi) 13T/14 Some menu items may be called differently, we will specify alternative paths. Also prepare a backup of important data: optimization sometimes requires resetting cache or deleting unnecessary files.

1. Disabling unnecessary system applications and services

By default. MIUI It installs dozens of pre-loaded apps, many of which duplicate Google features or work exclusively for the Chinese market. Mi Video, Mi Music, Mi Browser or GetApps (the Chinese app store) not only take up space, but also consume battery in the background. They cannot be removed by standard means, but can be disabled or frozen.

Methods of shutdown:

• 🔧 Through Settings: Go to Settings → Annexes → Manage applications, select an unnecessary application (such as Mi Community) and click Disable.This will remove it from the menu and stop background activity.
• ❄️ Freeze through ADB: For advanced users – connect your phone to your PC, turn on Debugging USB In Settings → The phone. → Version. MIUI (press 7 once MIUI" to activate the developer mode, then execute the command: adb shell pm disable-user --user 0 com.xiaomi.midrop Replace com.xiaomi.midrop with the desired application package (a list of packages can be found on the network).
• 🧹 Removal via Magisk: If you have root access, use the Universal Debloater module to mass-dispose of system debris.

Which apps can be safely disabled? Here's a list of the most useless for global users:

⚠️ Warning: Do not disable applications with com.android.* or com.miui.home packages, which may cause the system to fail. Also avoid removing com.xiaomi.findevice (needed to search for the device) and com.miui.securitycenter (security center).

2. Battery optimization: how to increase the operating time

One of the main claims to MIUI — The reason for this is the aggressive background activity of system processes such as miui.daemon or com.xiaomi.xmsf (a push notification service). Fortunately, most energy eaters can be tamed without losing functionality.

Step 1: Set up the battery mode

• 🔋 Go to Settings. → Battery and productivity → Battery mode and select Balanced (for most tasks) or Energy Saving (if you need to extend your running time). Performance mode only for games.
• ⚡ Turn off Adaptive Charging in Settings → Battery → Additionally, if you don't have battery problems, this feature limits the charge to 80% to extend battery life, but often doesn't work properly.
• 📵 Enable Charging Optimization (ibid.) if you leave your phone on overnight charging.The system will charge the battery to 100% just before waking up.

Step 2: Limit background activity

By default. MIUI It allows all applications to run in the background, which kills the battery, to fix it:

1. Go to Settings. → Annexes → Application management → Permits → Autorun and disable autorun for all unnecessary applications (especially social networks and instant messengers).
2. In the same menu, select Background Limitation and set Restricted mode for most apps (except messengers that must work in the background).
3. For Google Play Services (if you are not using Google Services), set a background limit to Do Not Allow.

Disable auto-start for social networks|Set the battery mode "Balanced"|Limit background activity of Google Play Services|Insert "Optimization of charging"|Disable adaptive charging (if not necessary)
