How to Save Battery on Xiaomi Redmi: Proven Methods for MIUI 14/13

Xiaomi Redmi is famous for its price-performance balance, but even the flagship models of the series (such as the Redmi Note 12 Pro+ or Redmi K60) often discharge faster than you would like, due to aggressive MIUI optimization, background processes and not always obvious power settings. In this article, we will discuss 15 practical ways to extend battery life by 20-50% depending on the use case, without resorting to radical measures like shutting down the mobile Internet.

Redmi’s flexible MIUI firmware allows you to fine-tune power consumption through hidden menus and modes. We tested all methods on devices with MIUI 13/14 (including Redmi 10C, Redmi Note 11 Pro and POCO X5 Pro) and selected only those that give a measurable effect without compromising convenience. For example, the correct setting of Advanced battery settings can reduce the consumption in standby mode from 5-7% to 1-2% per hour.

Important: Some tips require administrator rights or developer mode. If you're not ready for experimentation, focus on the basic sections (1-4). For advanced users, we've prepared instructions to disable MIUI Optimization and manually configure the CPU core.

1. MIUI Optimization: Hidden Energy Saving Settings

MIUI firmware contains built-in battery management tools, but they don't work well by default, starting with basic settings that can be changed without superuser rights:

• 🔋 Adaptive battery: Include in Settings → Battery → Battery settings → Adaptive battery: The system will analyze your habits and limit background activity of rarely used apps.
• 📉 Background Limitation: Go to Settings → Annexes → Application management → Autorun and disable Autorun for instant messengers, games, and social media (except for those critical for notifications).
• 🔄 Performance mode: C Settings → Additionally. → Select Balanced Mode over High Performance.

For models with MIUI 14, a new mode Ultra Battery Saver (on at 5% charge) has appeared, which turns off all background processes except calls and SMS.

1. Open the Settings. → Battery.
2. Put it on the icon. ⚙️ top-right.
3. Select Ultra Battery Saver → Enable manually.

💡

If, after updating, MIUI 14 Autonomy dropped, reset battery settings: Settings → Battery → ⋮ → Reset the battery settings. This will remove the stored usage patterns, but return the factory optimal settings.

⚠️ Warning: Do not turn on Ultra Battery Saver on a permanent basis - this will turn off push notifications and data synchronization (such as mail or weather.

2. Display setting: brightness, frequency, AOD

The screen is the main energy consumer at Redmi. AMOLED-panels (e.g. in Redmi) K50 Pro) Incorrect settings can eat up to 40 percent of the charge:

• ☀️ Adaptive Brightness: Turn it off in Settings → Display. → Adaptive brightness: Automatic adjustment often overstates brightness, wasting an extra 5-10% of charge.
• 🌓 Manual setting: Set brightness to 30-40% (comfortable for indoor eyes). For the street, use quick settings (swipe down).
• 🔄 Upgrade frequency: On models with 120 Hz (for example, Redmi Note 12 Pro)+) Switch to 60Hz in Settings → Display. → Upgrade rate. This saves up to 15 percent of the charge.

Pay special attention to Always-On Display (AOD). Nana AMOLED-He's spending screens. ~1% per hour, but by IPS (Like Redmi. 10A) — 3 to 5 percent:

1. Go to Settings → Lock screen.
2. Select the Lock Screen Style → AOD.
3. Turn off the slider or set a schedule (for example, only at night).

3. Background and auto-start management

Applications in the background are the second-largest battery eater, and MIUI aggressively caches processes even when they're not needed.

Step 1: Limiting background activity

• 🚫 Prohibition of Autostart: In Settings → Annexes → Application management → Autorun disable autorun for all applications except instant messengers and system services.
• 🔄 Background Limitation: In the same menu tap on the app → Limit background activity. This will prevent synchronization in the background.
• 📵 Disable notifications: For unnecessary applications (games, promotional mailings), turn off notifications in Settings → Notifications.

Step 2: Manual process control

If the phone is warm or discharged quickly, check the active processes:

1. Turn on Developer Mode (7 times tap on the MIUI version in Settings → About Phone).
2. Go to Settings → Additional → For Developers → Process Limits.
3. Set a maximum of 2 processes in the background (this will limit multitasking, but save up to 20% charge).

Disable autorun for games and social networks |Limit background activity of messengers |Set process limit on 2|Check active processes in Task Manager-->

⚠️ Attention: Limiting background processes to 2 may cause some applications (such as music players) to reboot when switching between tasks.

4. Connection optimization: Wi-Fi, mobile network, Bluetooth

Communications modules consume power even in standby mode, especially in areas with unstable signal, where the phone constantly switches between 4G/5G or searches for Wi-Fi networks.

• 📶 Network Mode: If you have Redmi with support 5G (Like Redmi. K60), But you don't use high-speed internet, switch to just 4G In Settings → SIM-maps and mobile networks → Preferred type of network.
• 🔄 Auto-connect to Wi-Fi: Disable automatic connection to open networks in Settings → Wi-Fi → Additionally. → Auto-connection to open networks.
• 🔌 Bluetooth: Turn off Bluetooth and NFC, If you don't use wireless headphones or payments, even when they're on standby, they spend. ~1-2% charge per hour.

For models with MIUI 14, Wi-Fi/mobile data smart switching (in Settings → Connections → Additional) is available. It automatically switches to the mobile network when the Wi-Fi signal is weak, but can increase battery consumption.

Hidden travel hack: If you are roaming, turn on Flight Mode and manually activate only Wi-Fi. This will prevent the operator from constantly searching for networks that eat up to 15% of the charge per day.

5. Synchronization and geolocation settings

Google and MIUI are constantly syncing data and positioning even when you sleep, and turning off unnecessary features can extend autonomy by 10 to 15 percent.

• 📍 Geolocation: Go to Settings → Confidentiality → Permits → Geodata and disable access for unnecessary applications. For Google Maps, set permission only while using.
• 🔄 Autosynchronization: Turn it off in Settings → Accounts. → Sync for unnecessary services (e.g. Mi Cloud, if you don’t use backup).
• 🕒 Synchronization Schedule: In Settings → Accounts. → Google → Sync your account, turn off automatic sync and update data manually.

For models with GPS-with a chip (all modern Redmi) it is useful to disable Accuracy Improvement (uses Wi-Fi and mobile networks to determine location). → Confidentiality → geodata → Regime. → The device is just.

⚠️ Note: Disabling Google Account Sync will stop updating your email, calendar, and contacts. If critical, leave sync enabled, but increase the refresh interval in each app’s settings (e.g., in Gmail, set Update manually).

6. Advanced Methods: Developer Mode and Processor Core

For users who are ready to dive into technical details, MIUI offers hidden settings that allow fine-tuning of power consumption.Caution: these methods require caution and can affect the stability of the system.

Step 1: Disabling MIUI Optimization

MIUI Optimization speeds up the interface, but increases the battery consumption to turn it off.

1. Activate Developer Mode (as described above).
2. Go to Settings → Additional → For developers.
3. Find Disable MIUI Optimization and activate the switch.
4. Reset the device.

Step 2: Setup the processor core

On devices with Qualcomm Snapdragon processors (for example, Redmi Note 12 Pro+ on Snapdragon 7 Gen 1), you can limit the maximum core frequency:

1. Install the Kernel Auditor app from Google Play.
2. Open the CPU partition and set the maximum frequency for big cores to 70-80% of the maximum (for example, for Snapdragon 7 Gen 1 - up to 2.2 GHz instead of 2.5 GHz).
3. Save the settings and restart the phone.

💡

Disabling MIUI Optimization and limiting the CPU frequency can increase autonomy by 25-30%, but reduce performance in resource-intensive tasks (games, video editing).

Step 3: Disconnecting Unnecessary Sensors

Some sensors (like a gyroscope or barometer) work in the background without even asking for applications to turn them off:

1. In Developer Mode, find Disable Sensors.
2. Select unnecessary sensors (e.g., Light Sensor if you are not using adaptive brightness).

7. Alternative firmware and custom cores

If standard methods don’t work, consider installing custom firmware. LineageOS or Pixel Experience, for example, are optimized for energy efficiency and lack the “heavy” features of MIUI.

The advantages of custom firmware:

• ⚡ Absence of background processes MIUI (saving up to 40% of charge).
• 🔧 More flexible energy saving settings.
• 📱 Regular security updates.

Cons:

• ⚠️ Loss of warranty (when unlocking the bootloader).
• 🔌 Possible bugs with camera or sensors.
• 🔄 Difficulty of installation for beginners.

For custom firmware installation:

1. Unlock the bootloader through the Mi Unlock Tool (requires a wait of 7-14 days).
2. Install TWRP Recovery.
3. Sweep through the firmware and GApps (Google services).

⚠️ Warning: Wrong firmware can turn your phone into a brick.Before you start, backup through TWRP Check firmware compatibility with your Redmi model on the forum XDA Developers.

8 Hardware methods: charging and battery maintenance
