Xiaomi smartphones are known for their price-performance ratio, but many users face one problem: the battery goes down too quickly. Even flagship models like the Xiaomi 14 Ultra or Redmi Note 13 Pro+ require heavy use to recharge by the evening, the reasons are not only in battery capacity, but also in the features of the MIUI firmware, application background activity and hardware settings.
In this article, we’ll discuss 12 working methods to increase Xiaomi’s autonomy by 20 to 50 percent without radical casualties. From simple tweaks to hidden engineering menu features, you’ll learn how to keep the battery longer on Poco, Redmi or Mi series. All tips have been tested on current versions of MIUI 14/15 and HyperOS, but most will work for older models as well.
1. Optimization of background activity in MIUI
The default MIUI firmware aggressively manages background processes, but often it works against the user. For example, instant messengers like Telegram or WhatsApp may not receive notifications on time due to system limitations, while some applications continue to eat the battery in the background.
To balance autonomy and functionality:
- 🔧 Open the Settings. → Annexes → Manage applications and select Auto Run. Disable Auto Run for unnecessary applications (such as games or social networks you rarely use).
- 📱 Go to Settings. → Battery and productivity → Battery management: Set the critical applications (messaging, mail) in Unlimited mode, and the rest optimized.
- ⚡ Turn on the Adaptive Battery in the same section – this feature analyzes your habits and limits background activity during off-hours.
💡
If notifications stop coming after the restrictions, add the app to the White List in the battery settings, which ensures that MIUI will not put it to sleep.
On HyperOS models (such as Xiaomi 14 or Poco F6), the path is slightly different: Settings → Battery → Battery Mode. Here you can choose between Balanced, Long Life (maximum Autonomousity) and Performance.
Configuring energy-saving regimes
MIUI has three levels of energy saving, but most users don't even know they exist. Let's figure out when and how to use them:
| Regime. | The effect on autonomy | Limitations | When to include |
|---|---|---|---|
| Balanced | +10-15% of the time of work | Moderate background restriction, decrease in processor clock frequency | Constantly for everyday use |
| Super energy saving | +30-50% of the time of work | Disables mobile Internet, restricts applications, reduces brightness | When traveling or when the charge is below 15% |
| Ultra energy saving | +50-70% of the time of work | Only calls, SMS and a few selected applications work | Critical situations (charge < 5%) |
To activate the modes:
- Go to Settings → Battery and Performance → Battery Mode.
- Select the mode you want. Super and Ultra may require confirmation.
- In Ultra mode, you can manually add up to 5 apps that will work (such as maps or instant messenger).
On models with a Snapdragon 8 Gen 2/3 processor (such as the Xiaomi 13T Pro or Poco F5 Pro), the Ultra mode can increase autonomy by up to 80% due to the deep limitation of the CPU cores. This is due to the chipset architecture, which allows flexible power management.
3. Screen optimization is the main devourer of the battery
The display consumes up to 40-60% of the battery charge in active use. AMOLED-screens (like Xiaomi 13 Lite or Redmi) K60) Incorrect settings can reduce the time of operation by several hours:
- 🌓 Set adaptive brightness to 70-80% of maximum. → Display. → Brightness turn off Autobrightness and manually select a comfortable value.
- ⏱️ Set up screen timeout: Settings → Display. → Sleep after. Optimum 15 or 30 seconds.
- 🎨 For AMOLED-Turn on the Dark Theme (Settings) → Display. → Dark mode. This reduces consumption by 15 to 25%.
- 🔄 Turn off the screen always on (AOD) — It eats up to 5-7% of the charge per hour.
Brightness ≤ 80% |Timeout screen ≤ 30 seconds |Dark theme enabled |AOD disabled |Adaptive refresh rate enabled-->
On flagships with LTPO support (e.g. Xiaomi 14 Pro), enable Adaptive Update Rate in Settings → Display → Update Rate. This will allow the screen to automatically switch between 1 Hz (for static images) and 120 Hz (when scrolling).
⚠️ Note: On cheap models (e.g. Redmi) 12C) The adaptive frequency may not work properly and may even increase consumption.
4. Connection management: Wi-Fi, 5G, Bluetooth
Communications are the second-largest consumer of power after the screen, and if you optimize them, you can get 10 to 20 percent autonomy, and let's start with the most voracious, mobile Internet.
- 📶 Turn it off. 5G, if you don't need it. → SIM-maps and mobile networks → Type of network, select 4G (preferably). 5G Consumes 25-40% more energy.
- 🔄 Enable automatic switching between 4G/3G In the same menu, this will prevent you from constantly searching the network. 5G.
- 📡 Turn off Wi-Fi and Bluetooth when not in use, or set up automatic shutdown via Settings → Connections and sharing → Wi-Fi → Additionally. → Turn off Wi-Fi in sleep mode.
- 📍 Turn off the Permanent search for Wi-Fi networks in the Wi-Fi settings (Section Additional).
For HyperOS devices (e.g. Xiaomi 14), a new feature has been introduced, Smart Network Switching, which automatically chooses between Wi-Fi and mobile internet depending on signal quality, saving charge. Enables in Settings → Mobile Network → Smart Switch.
How to check which app is using mobile traffic in the background?
If you use Bluetooth headphones frequently (such as the Xiaomi Buds 4 Pro), turn on Low Power Mode (if supported) in their settings, and check if Bluetooth is still on after the headphones are turned off, a common MIUI error.
5. Disabling unnecessary functions and services
MIUI is overloaded with functions, many of which are background and charge-consuming, and this is what you can safely turn off:
- 📍 Geolocation: Disable it for unnecessary applications in Settings → Confidentiality → Permits → Geodata, leave it for maps and messengers only.
- 🔍 Device Search: Find the device is useful, but constantly uses it GPS. Turn it off in Settings. → Google → Security → Find my device (if you are not using it).
- 📊 Analytics MIUI: Go to Settings. → The phone. → Reviews and analytics and disable Submitting Usage Data.
- 🎤 Voice Assistant: If you don’t use Google Assistant or Xiao AI, Turn them off in the application settings.
- 🔄 Auto Update Apps: In Google Play, disable auto-update or install it over Wi-Fi only.
Pay special attention to Google Play Services, which is often hanging in the background and consumes up to 10% of the charge to limit it:
- Go to Settings → Applications → Application Management → Google Play Services.
- Select Battery → Battery Consumption Management and install Limited.
- Turn off Auto Update in the application settings.
💡
Even after disabling unnecessary services, MIUI can turn them on periodically after updates. Check the settings every 1-2 months!
Hardware methods: from calibration to battery replacement
If the software isn't working, maybe the problem is with the battery itself or the power controller.
- 🔋 Battery calibration: If the phone suddenly turns off at 15-20% charge, the battery requires calibration. Completely discharge the device before switching off, then charge to 100% without interruptions. Repeat 2-3 times.
- 🔌 Battery replacement: Average battery life is 2-3 years if capacity has fallen below 80% of the original (checked in Settings) → Battery → Battery status, it's time to change.
- 🛠️ Cooling: Overheating reduces battery life. Avoid charging during games or in direct sunlight.
- ⚡ Fast Charging: Constant use of Turbo Charge (30W/67W/120W) It speeds up battery degradation, and it's better to use standard charging for everyday use. 10W–18W adapter.
To check the actual state of the battery, use the engineering menu:
Enter the phone code in the app: ##4636##
Go to the section "Battery Information"⚠️ Note: If the battery temperature above 40 is displayed in the engineering menu°C in normal mode or 45°C when charging, it's critical! Immediately stop using the device and contact the service center - high risk of battery bloating.
On models that support wireless charging (for example, Xiaomi 13 Pro or Mix Fold 3) avoid constant use of Qi-charging – it is 15-20% less efficient and heats the battery more.
7.Alternative firmware and cores for advanced users
If you're willing to take drastic measures, custom firmware can greatly improve autonomy.
- 📱 Pixel Experience: firmware based on pure Android without unnecessary services MIUI. Increases autonomy by 15-25%.
- ⚡ LineageOS: Lightweight firmware with minimal background consumption.
- 🔧 Castom cores: For example, FrancoKernel or Kirin Kernel to optimize processor power consumption.
Before installing custom firmware:
- Unlock the bootloader via Mi Unlock Tool (requires a Xiaomi account and wait 7-14 days).
- Install TWRP Recovery for your model.
- Make a full backup with TWRP or Mi Flash Tool.
- Select a stable firmware version on the XDA Developers or 4PDA forum.
Risks of custom firmware
For users who are not ready for full flashing, there is a safer option – disabling advertising and unnecessary services MIUI through ADB:
adb shell pm uninstall --user 0 com.miui.analytics
adb shell pm uninstall --user 0 com.xiaomi.joyose
adb shell pm uninstall --user 0 com.miui.systemAdSolution8 Additional Tips for Maximum Autonomy
A few unobvious tricks that will help squeeze even more out of the battery:
- 🌙 Night mode: Turn on Dark theme and Night light (Settings) → Display. It's not just about reducing consumption. AMOLED-screen, but also reduces the burden on the eyes.
- 📴 Airplane Mode: If you don't need calls but need savings (e.g., on a trip), turn on Airplane Mode and manually activate Wi-Fi. This turns off the energy-consuming cellular network search.
- 🔕 Vibration: Turn off vibration when typing and notifications in Settings → Sound and vibration: Vibromotor uses up to 5% of its charge per day.
- 📂 Cache Clearing: Clean the app cache regularly in Settings → Warehouse → Clear the cache. Clogged cache can lead to increased consumption of RAM and, as a result, batteries.
For owners of infrared port devices (e.g. Redmi Note 12 Pro+): disable it in Settings → Connections and Sharing → Infrared port if you do not use the remote control.
💡
The most effective way to extend autonomy is to combine software and hardware techniques, such as turning off 5G + dark theme + super energy saving can add up to 50 percent of the time.
