Xiaomi smartphones are some of the most popular on the market due to their price/quality ratio, but many users are facing rapid battery discharge, and the reasons are not only in battery capacity, but also in the features of MIUI firmware, background processes and hardware settings. In this article, we will discuss 15 proven ways to reduce power consumption, from obvious (but often ignored) to hidden features that are not written in the official instructions.
It's important to understand that there is no universal solution. 12 s AMOLED-The screen is used by the same methods, POCO X5 s IPS — We'll show you what advice is relevant for specific models and versions. MIUI 13/14/15. You’ll also learn how to track “gluttonous” apps with built-in tools and why to disable them. 5G on some chipsets (e.g. Snapdragon) 7 Gen 2) can save up to 18% charge-by-charge 8 hours.
1. Screen optimization: brightness, refresh rate and technology
The display is the main consumer of power in a smartphone. On models with AMOLED (for example, Xiaomi 13 Pro or Redmi K60), the savings are achieved differently than on IPS (as in the POCO M5).
- 🌓 Adaptive brightness: Enable in Settings → Display. → Brightness. MIUI 14+ The algorithm takes into account the light and time of day, but sometimes “overstates” the values – check manually in bright sun.
- 🔄 Upgrade frequency: on flagships (Xiaomi 13 Ultra) set 60 Hz instead of 120 Hz. The difference in smoothness is minimal, and savings up to 20% charge.
- 🖤 Dark subject. + AMOLED: On screens with this technology, black pixels don't consume energy. → Display. → Dark theme and use black-dominated wallpaper.
For advanced users: in Settings → Special features → Color correction is Gradation of Grey mode. It turns off color reproduction, which reduces the load on the GPU. Minus is a monochrome interface, but the savings are 10-15%.
💡
On the Xiaomi 12S Ultra and the new flagships, there is a hidden feature called "Energy-saving AMOLED". To activate it, type the phone code ##36446337## in the Phone app, then select AMOLED Power Save Mode.
2. MIUI settings you didn't know about (or ignored)
MIUI hides a few useful options for saving energy, most of which are in the Settings → Battery section, but there are also "secret" ways:
- 🔋 Ultra-low mode: activated at 15% charge, but can be manually enabled via Settings → Battery → Battery modes → Ultra-low consumption: Disables background activity of all applications except calls and SMS.
- ⚡ Optimization of charging: in Settings → Battery → Charging settings turn on "Adaptive Charging" and it analyzes your habits and slows your charging down to 80% if your phone is connected overnight.
- 📵 Background Limitation for Applications: C Settings → Annexes → Application management → Auto-run disable auto-run for instant messengers and social networks. 5-7%.
Little-known life hack: MIUI 14+ has a Deep Optimization feature that analyzes battery usage over the past 7 days and offers personalized recommendations. To run it, go to Settings → Battery → Cog Badge (top) → Deep Optimization.
3. Background processes: how to stop the "invisible devourers" of charge
Even when the screen is off, the smartphone continues to waste energy on background tasks.
- 🤖 Google Play Services: can consume up to 12% of the charge per day. → Battery → Battery usage. If the value is high, clear the cache in Settings. → Annexes → All applications → Google Play Services → Memory. → Clear the cache.
- 📱 MIUI System Launcher: on some models (Redmi 10, POCO X3) It consumes up to 8% of the animation. → The phone. → Version. MIUI (Tap 7 times, then in the Developer → The scale of the animation window / transition set off..
- 📊 Analytics and statistics: Xiaomi collects usage data. → Confidentiality → Special access → Usage statistics.
For the advanced: use ADB-commands to deeply limit the background. Connect the phone to the PC and do it:
adb shell cmd appops set com.google.android.gms RUN_ANY_IN_BACKGROUND deny
adb shell cmd appops set com.miui.home RUN_ANY_IN_BACKGROUND denyList of the most voracious applications on Xiaomi (according to MIUI Analytics, 2026)
4. Communications and Networks: 5G, Wi-Fi and GPS under Control
Communications are the second largest consumer of power after the screen, and we optimize them.
| Technology | Consumption (per hour) | How to reduce costs |
|---|---|---|
| 5G | 8-12% | Switch to the switch. 4G In Settings → SIM-maps and mobile networks → Preferred type of network → 4G |
| Wi-Fi (constant search) | 5-7% | Turn off Network Search in Settings → Wi-Fi → More |
| GPS (high accuracy) | 15-20% | Use Charge Saving Mode in Settings → Location → Mode |
| NFC | 2-3% | Disable Settings → Connection and Sharing → NFC if you don’t use contactless payment |
Critical: On MediaTek Dimensity chipsets (like the Redmi Note 12 Pro+), the 5G module consumes 30% more than Snapdragon. If 5G coverage is weak in your region, switch to 4G forcefully.
💡
On Xiaomi, two SIM-Disabling the second slot (if not used) saves up to 5% of charge per day.
5. Hardware chips: processor, sensors and vibration
Even the "iron" can be adjusted to save:
- ⚙️ Productivity Limitation: C Settings → Battery → Battery modes, select Charge Savings, which will lower the CPU clock speed by 20-30%, but extend the working hours 1.5-2 hour.
- 🔊 Vibration and sounds: Turn off vibration when typing in Settings → Sounds and vibrations → Vibration when dialing. Also reduce the duration of vibration of notifications.
- 🌡️ Sensors: Turn off the Approach Sensor (if you don’t use smart cases) via Settings → Special facilities → Approximation sensor.
For owners of POCO F5 and other models with Snapdragon 7+ Gen 2: in the engineering menu (#4636##) you can manually restrict the cores of the processor. Go to Information → Usage Time Control and set a limit for background tasks.

6.Apps and services: what can be turned off without loss
Many Xiaomi system services work in the background, but not all are needed by the user.
- 📦 Mi Video/Mi Music: If you don’t use standard players, turn them off in Settings → Annexes → All applications → [Name of name] → Shut down.
- 📡 Mi Share: A wireless file transfer feature that constantly scans devices. → Connection and exchange → Mi Share.
- 🔍 Device search: in Settings → Google → Devices and exchanges → Search device turn off search near.
Warning: Do not disable MiuiDaemon or SecurityCenter, this will cause system failures, and avoid turning off Google Play Services, or many applications will stop working.

7 Updates and firmware: when newer versions of MIUI save power
Checklists before updating:
⚠️ Note: If your Xiaomi is released before 2020 (like the Redmi Note 8 Pro), upgrade to the next one. MIUI 14+ can increase battery consumption due to new background services. Check reviews on forums (for example, 4PDA) before installation.
On the other hand, some updates bring optimizations:
- 🔄 MIUI 14: Added Adaptive Charging and Improved Background Process Management.
- 📉 MIUI 15 (for new models): promises 15% better autonomy through optimization of the Android 14 kernel.
How to check if you need to update:
- Go to Settings → About the phone → System update.
- Check out the firmware version and compare it with the latest reviews on thematic forums.
- If your model is on the "recommended upgrade" list (e.g. Xiaomi 12T, Redmi K50), install. For older smartphones (Redmi 9), it's better to stay on the current version.
8 Extreme measures: when nothing helps
If after all the settings, the battery sits down in half a day, it’s time for radical steps:
- 🔄 Reset to factory settings: removes accumulated debris in the system. → The phone. → Reset settings. Important: pre-reverse Settings → Additionally. → Backup and reset.
- 🛠️ Battery replacement: if the capacity has fallen below 70% (checked in Settings) → Battery → The battery condition, even the most radical settings will not help. The cost of replacing on the official service is from 1500 to 4000 rubles depending on the model.
- 📱 Install custom firmware: for example, LineageOS or Pixel Experience often saves better charge than standard MIUI. The disadvantage is the loss of warranty and possible bugs with the camera/NFC.
⚠️ Note: Xiaomi with a locked bootloader (Redmi Note 11 and later) requires unlocking through the Mi Unlock Tool to install custom firmware.
