Xiaomi smartphones are famous for their price-performance ratio, but even flagship models like the Xiaomi 14 Ultra or Redmi Note 13 Pro+ discharge faster than you would like, not only because of the battery capacity, but also because of the MIUI firmware, which is optimized by default for speed rather than energy efficiency. In this article, we will discuss 15 ways to extend autonomy, from basic settings to hidden functions, which are not even in official instructions.
Xiaomi’s feature is that many features save charge only when set up correctly. For example, the MIUI power saving mode works differently than on Android’s runoff: it not only limits background activity, but also blocks updates for system applications (like com.miui.securitycenter). And in models with Snapdragon processors (like POCO F5 or Black Shark 5), you can manually limit the clock speed of cores – this will give +15-20% of the time without recharging.
It's important to understand that there's no universal solution. On the budget Redmi 12C with a 5,000 mAh battery, the priority is to turn off everything superfluous, and on the top Xiaomi 13T with Dimensity 8200-Ultra, it's better to adjust adaptive brightness and process control. We divided the tips into categories: from simple (for beginners) to advanced (for those who are willing to dig into the developer settings).
1. Screen optimization: brightness, frequency, AMOLED-chips
The display is the main energy eater in any smartphone. AMOLED-screens (e.g. Xiaomi) 12T or POCO X5 Pro) you can save up to 30 percent of your charge if you adjust the color palette and refresh rate correctly:
- 🌓 Adaptive Brightness: Include it in Settings → Display. → Brightness, but calibrate manually. MIUI It often lowers the brightness in the room, causing the eyes to get tired and the battery to be wasted. 30-40%.
- 🔄 Update frequency: on models with support 90/120/144 Hz (e.g. Redmi) K60) switch over 60 Hz in Settings → Display. → Update frequency. That'll give you +10-15% autonomy.
- 🎨 Dark subject. + AMOLED: Activate the dark mode in Settings → Display. → Dark subject. AMOLED-In the screens, black pixels are not illuminated, which reduces energy consumption.
On models with a Snapdragon processor 8 Gen 2 (for example, Xiaomi 13 Pro) refresh rate 120 Hz paired with QHD-permitting 40% charge-by-charge 4 hour of active use. Switch to Full HD+ and 60 Hz increases autonomy to 6-7 hours.
⚠️ Note: On certain devices (e.g, POCO F4 GT) Forced reduction of refresh rate to 60 Hz can cause artifacts in games. Before changing, check if your model supports adaptive mode.
| Xiaomi model | Screen type | Optimal frequency (Hz) | Saving charge |
|---|---|---|---|
| Redmi Note 12 Pro+ | AMOLED, 120Hz | 60 | 25% |
| Xiaomi 13 Lite | AMOLED, 120Hz | 90 | 15% |
| POCO X5 | AMOLED, 120Hz | 60 | 30% |
| Redmi 12C | IPS, 60 Hz. | 60 | no effect |
MIUI settings: hidden energy saving features
MIUI offers several power saving modes, but most users use only the basic one. Meanwhile, more efficient tools are hidden in Settings → Battery and Performance:
- 🔋 Ultra-power saving mode: restricts all background processes, turns off mobile internet in the background and reduces processor performance, suitable for emergency situations (for example, when the charge is at 5% and you need to wait for charging).
- ⚡ Optimization of charging: in Settings → Battery and productivity → Battery settings enable Optimized Charging.This will slow battery wear, limiting charge to 80% (configurable).
- 📵 Background Limitation for Applications: Go to Settings → Annexes → Permits → Auto-run and disable auto-run for unnecessary programs (such as games or social networks) to prevent them from running in the background.
Pay special attention to Settings → Battery and Performance → Battery Use. This shows the applications that consume the most power. If you find yourself on the top of the list com.miui.home or com.android.systemui, this is a signal that the firmware is not working properly, try resetting or updating the MIUI.
Disable auto-run of unnecessary applications |
Enable ultra-power saving mode at 10% charge |
Activate optimized charging (up to 80%)|
Disable background synchronization for email and social networks-->
⚠️ Note: Some models (e.g. Redmi) 10C) Ultra-power saving mode can block notifications from messengers. Before activating, check if push notifications are critical for you.
3. Communications management: mobile Internet, Wi-Fi, Bluetooth
Communications are the second largest consumer of power after the screen, especially 5G and Wi-Fi 6, which are constantly scanning the networks in the background.
- 📶 Turn it off. 5G, If not necessary: in Settings → SIM-maps and mobile networks → Type of network Select Only 4G. On models with Snapdragon 888 (for example, Xiaomi) 11T Pro) 5G-The modem consumes 20% more power even if you don’t use high-speed internet.
- 🔌 Wi-Fi and Bluetooth: Turn them off when not in use. MIUI There is a function of automatic Wi-Fi shutdown when the screen is locked – activate it in Settings → Wi-Fi → Additionally. → Turn off Wi-Fi when blocked.
- 📡 Aircraft mode in subway/elevator: when the signal is weak (1-2 dividing, the phone uses more power to find the network, turn on the plane mode in subways or densely populated areas with poor coverage.
For dual-SIM devices (e.g. Redmi Note 12 Pro): If you only use one SIM-map, disable the second in Settings → SIM-maps and mobile networks, even inactive SIM Expends the charge of searching the network.

4.Apps and background activity: what to turn off first
According to Xiaomi, up to 40 percent of battery consumption is due to the background of applications, with social media, instant messengers and games at the top of the culprits.
- 📱 Background Limitation for Google Play Services: This system application (com.google.android.gms) often wakes up the processor to sync. To limit it, go to Settings → Annexes → Application management → Google Play Services → Battery → Limit background activity.
- 💬 Messengers: on Telegram and WhatsApp, turn off automatic download of media files (in chat settings). In Viber, limit background activity through settings MIUI.
- 🎮 Games: Even after closing games like Genshin Impact or PUBG Mobile can continue to work in the background. Use the settings → Annexes → Application management → [play-off] → Forced stopping.
For advanced users, the developer settings (how to enable — see next section) include the option Don't keep activities. If activated, Android will close apps as soon as you fold, but this may disrupt some features (such as notifications).
💡
To quickly close all background apps, hold the Home button (or swipe up and hold on gesture control) and tap the shopping cart icon. This will work more effectively than manually closing each application.
5. Developer Settings: Hidden Tricks to Save Money
The developer settings menu in MIUI opens up access to functions that are hidden by default. To activate it, go to Settings → About Phone and 7 times click on the MIUI Version. Then a new section will appear in Settings → Additional. The most useful options for saving power:
- 🛠️ Limitation of background processes: c Developer settings → Annexes → The limit of background processes select the maximum 2 This will reduce the battery consumption of 10-15%, It may cause some applications to reboot.
- 🔄 Disabling animation: in Developer Settings → Windows animation, transition animation and animator duration set the value Animation disabled. This will speed up the system and reduce the load on the processor.
- 📊 Monitoring of use CPU: Turn on the display of use CPU This will help you track which processes are loading the system (e.g. mediaserver or Android.system).
On devices with MediaTek processors (for example, Redmi Note 12 or POCO M5) in the developer settings there is an additional option CPU performance Limit. If you turn it on, the system will automatically reduce the clock frequency when it is down, which gives +5-10% autonomy.
⚠️ Attention: Changing the settings in the developer settings can lead to unstable phone performance, such as limiting background processes to 1-2 It can cause errors in instant messengers or banking applications.
Hardware methods: battery, temperature, charging
In addition to software settings, the autonomy is also influenced by physical factors: ambient temperature, battery status and how you charge.
- 🔥 Avoid overheating: at temperatures above 40°C battery degrades 2 times faster. Do not leave the phone in the sun or near heat sources (for example, on a torpedo in a car). On liquid-cooled models (for example, Black Shark 5 Pro) monitor the fan - its constant turning on signals overheating.
- 🔌 Charging to 80%: as mentioned earlier, in MIUI There's an optimized charging function. It limits the charge to 80%, This increases the battery life by 30-40%. Included in Settings → Battery and productivity → Battery settings.
- 🔋 Charger quality: Use original or certified charges. Cheap analogs can not only damage the battery, but also increase the charging time, which leads to additional heating.
On wireless charging devices like the Xiaomi 13 Pro, this method is 20% less efficient than wired charging and heats up the phone more. If autonomy is critical, opt for cable.
| Temperature. | Impact on the battery | Recommendations |
|---|---|---|
| Lower 0°C | Capacity reduction by 20-30% | Do not use your phone in the cold for more than 10 minutes. |
| 10-35°C | Optimal regimen | Ideal conditions for work |
| 35-45°C | Accelerated degradation | Turn off resource-intensive tasks |
| Above 45°C. | Irreversible damage | Refrigerate the device immediately. |
7.Alternative firmware and cores: for advanced users
If you're willing to go beyond standard MIUI settings, consider installing a custom firmware or core that gives you full control of energy management, but requires unlocking the bootloader and losing warranty.
- 📱 LineageOS: lightweight firmware without unnecessary services Xiaomi. on the Redmi Note 10 Pro with LineageOS 20 battery lasts 25% longer than on the MIUI 14.
- ⚡ KernelSU + FrancoKernel: a modified core with fine-tuning of the CPU and task scheduler frequencies, allowing you to limit the maximum clock speed to save money.
- 🔧 Magisk modules: for example, Greenify or Battery Charge Limit for flexible charging and background management.
Warning: Installing custom firmware requires unlocking the bootloader, which resets the phone to factory settings and voids the warranty, IR-blaster NFC) Before installing, check compatibility with your model in the forums. XDA Developers or 4PDA.
💡
Custom firmware provides maximum autonomy, but requires technical skills, and for most users, optimizing standard MIUI is enough.
