How to reduce power consumption on Xiaomi: proven methods for all models

Xiaomi smartphones are famous for their price-performance ratio, but even flagship models like the Xiaomi 14 Ultra or the budget Redmi Note 13 face the problem of fast discharge. MIUI — In this article, we will discuss system and hardware methods that can reduce power consumption by 20-50% without compromising the user experience.

It's important to understand that there's no one-size-fits-all solution. Each method depends on the device model, the version. MIUI (or HyperOS on new devices) and individual use cases, such as owners POCO F5 with a Snapdragon 7 processor+ Gen 2 is worth paying attention to performance settings, and users of Redmi A2 We tested all the methods on devices from 2022 to 2026, and only those that produce noticeable results were selected.

1. Optimization of settings MIUI/HyperOS

Xiaomi’s proprietary shell offers many hidden power management features, but they are often hidden in the back of the menu, starting with basic settings that maximize the effect with minimal effort.

The first thing to do is go to Settings. → Battery and productivity → Battery mode. There are three options available:

• 🔋 Balanced is the best choice for most users, limiting background activity but not blocking notifications.
• 🌿 Charge savings - aggressively reduces consumption by turning off synchronization and background processes.
• ⚡ Performance: maximum power without restrictions. Use only when you are under active loads (games, video editing).

For HyperOS devices (e.g. Xiaomi 14 or X-ray) POCO X6 Pro) added a fourth mode, Adaptive, which analyzes user habits and automatically switches between profiles, works more effectively than manual settings, but requires 2-3 days of "training".

Second Critical Item – Settings → Battery and productivity → Battery use: This shows the apps that consume the most energy, and if you have social media (TikTok, Instagram) or instant messengers (Telegram, WhatsApp) on the top, you have to manually restrict them:

1. Stick to the app on the list.
2. Choose to limit background activity.
3. Turn off AutoRun and Precise Location Determination (if not critical).

💡

On HyperOS devices, we've got a Deep Optimization feature that analyzes user habits and offers personalized recommendations. → Battery → Battery recommendations.

2. Setup auto-start and background processes

One of the main "energy-eating" properties MIUI — Even after closing, many programs continue to work in the background, updating data and sending notifications, not only for social networks, but also for system services like Mi Cloud or Security.

To disable autostart:

1. Go to Settings → Applications → Application Management.
2. Select AutoRun (on some models, path: Settings) → Battery → Auto-start).
3. Disable unnecessary apps. Leave only messengers and critical services (such as Google Play Services).

For full control over background processes, use the developer mode:

• Activate it by tapping it 7 times on the version MIUI In Settings → The phone.
• Back to Settings → Additionally. → For developers.
• Find the item Limit background processes and set the value of the maximum 2 process.

On devices with Qualcomm Snapdragon (e.g. Xiaomi) 13T or POCO X5 Pro) there is an additional option - Optimization MIUI It can increase productivity, but it can reduce battery life by 10 to 15 percent.

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

Wireless communication modules are one of the main sources of energy consumption, and even when they are in standby mode, they constantly scan networks and maintain connection, and let's consider how to minimize their impact:

Wi-Fi and mobile data:

• 📶 Turn off Wi-Fi Network Search in the background in Settings → Wi-Fi → Additionally.
• 🔄 Use Automatic Switch to Mobile Data only when necessary (set up in the same menu).
• 📡 HyperOS devices have Adaptive Connection, which automatically switches between Wi-Fi and the mobile network depending on the signal quality, and to save battery life, it's better to turn it off.

Bluetooth and NFC:

• 🔵 Turn off Bluetooth if you don't use a headset or smartwatch.Even when it's standby, it consumes ~5% charge per day.
• 🏷️ NFC On some models (e.g. Redmi Note 12 Pro)+) It remains active after use.

Mobile network:

• 📶 Switch to Just. 4G In Settings → SIM-maps and mobile networks → Preferred type of network. 5G Increases battery consumption by 20-30%.
• 🔄 Turn off the improved call quality (VoLTE/VoNR), If you don't call often, this feature keeps the communication module active.

💡

On devices with MediaTek Dimensity (e.g. Redmi Note 13 Pro)+) The power consumption of the mobile network is 10 to 15 percent higher than that of Snapdragon, which is due to the architecture of the modems.

4. Brightness and display control

The screen is the main consumer of energy in a smartphone. AMOLED-The consumption of displays (installed in most Xiaomi models since the Redmi Note 11) depends on the color of the content displayed. Black pixels do not consume energy, so dark themes provide real savings.

Main settings:

• 🌓 Include Dark Theme in Settings → Display. → Dark subject. AMOLED-This reduces the consumption of screens by 15-20%.
• ☀️ Set Adaptive Brightness, but limit the maximum to 60-70%. Manual Brightness can be reduced to a comfortable 40-50%.
• ⏱️ Reduce screen timeout to 15–30 seconds (same display menu).
• 🔄 Turn off the always-on display (AOD). This feature eats up to 5% charge per hour.

For devices with 120 Hz or 144 Hz displays (e.g, POCO F5 Xiaomi 13T Pro has an option called Adaptive Update Rate, which automatically reduces the frequency to 60 Hz when you view static content (social media, reading). → Display. → Screen refresh rate.

Turn on the dark topic|Set adaptive brightness (max. 70%)|Reduce screen timeout to 15 seconds|Turn off Always-On Display|Activate the adaptive refresh rate (if any)

-->

Xiaomi 14 Ultra and other flagships with LTPO-Adaptive frequency works more efficiently with displays - it reduces power consumption to 1 Hz in standby mode, which gives +2-3 hours of autonomy.

Hardware methods: battery and charging

Power problems don't always have to do with the software, and over time, lithium-ion batteries lose capacity, and improper charging speeds up the process, and here's what you can do at the hardware level:

Checking battery status:

• Enter the code ##4636## in the phone application.
• Select Battery Information and see Health Level, a value below 80% indicates a need for replacement.

Proper charging:

• 🔌 Use the original chargers. Xiaomi's Fast Charging (33W/67W/120W) It is safe but reduces the battery life 10–15% yearly.
• 🔋 Keep the charge level in the range of 20-80%, full discharge and charge up to 100% accelerate degradation.
• 🌡️ Avoid overheating.If the phone heats up above 40°C during charging, remove the case and disconnect from the network.

New models (Xiaomi 14, POCO X6) And we have Adaptive Charging, which analyzes the user's habits and slows down the charging after 80 percent if you're asleep. → Battery → Battery status.

💡

If your Xiaomi supports wireless charging, use it only in extreme cases: energy loss during induction charging reaches 30-40%, and battery heating increases.

Battery replacement: If the capacity has fallen below 70%, consider replacing. Xiaomi's official service centers offer original batteries for 2,000 to 4,000 rubles (depending on the model), informal counterparts are cheaper, but can last 2-3 times less.

6.Apps and services that drain the battery

Some programs consume energy in the user's eyes, and here's a list of the most voracious and how to optimize them:

Pay special attention to Google Play Services, which cannot be removed, but you can limit:

1. Go to Settings → Applications → Application Management → Google Play Services.
2. Choose the Battery. → Limit background activity.
3. Turn off Auto Update in the Google Play Store settings.

For owners of HyperOS devices, Freeze Applications, which completely stops background activity of selected programs without removing them. → Annexes → Application freeze.

💡

Memory cleaning applications (e.g. Clean Master or DU Battery Saver not only doesn't help, it makes things worse, they're constantly working in the background, scanning the system, and they're consuming extra energy.

7. Additional chips for advanced users

If standard methods don't work well, try these advanced techniques, which take longer to set up, but can increase autonomy by 30 percent or more.

Disabling unnecessary sensors:

• 📍 GPS: Turn off High Precision Location Determination in Settings → Location → Mode. Use only on the networks.
• 🎤 Microphone: Limit microphone access for unnecessary applications → Confidentiality → Permits.
• 📷 Approximation Sensor: In some models, it remains active even when the screen is off. Disables via Developer Mode (Disable proximity sensor).

Use of the ADB deep-optimize:

With the help of teams ADB You can turn off system applications that can't be removed by standard methods, like Mi Video, Mi Music or GetApps:

adb shell pm uninstall --user 0 com.mi.videoplayer


adb shell pm uninstall --user 0 com.mi.android.globalFileexplorer

A complete list of removal packages can be found on the forums 4PDA or XDA Developers for your model.

Cores and planners:

On devices with an unlocked bootloader, you can install a custom core (such as FrancoKernel or Kirisakura) that optimizes power consumption at the system level, and you can also change the I/O scheduler to cfq or bfq for more efficient resource management.

Substitution DPI permissions:

Reduced screen resolution (e.g., with FHD+ before HD+) It reduces the load on the GPU, and you can do it through ADB:

adb shell wm size 720x1280


adb shell wm density 320

Once rebooted, the interface will become less clear, but autonomy will increase by 10-15%, and you can return the standard settings with the adb shell wm size reset command.

8 When nothing helps: radical measures

If all of the above methods have failed, it may be that the problem is in the hardware or deep in the system.

Reset to factory settings:

Sometimes accumulated system errors or conflicting applications lead to increased energy consumption.

1. Make a backup of the data through Settings → Google → Backup.
2. Go to Settings → About the phone → Reset settings.
3. Select Delete all data.

Battery replacement:

If the phone runs out in 2 to 3 hours with minimal load, it's likely that the battery is worn out. Check its condition via ##4636## or the AccuBattery app. With a capacity below 70% of the original, you need to replace it.

Transition to custom firmware:

Official firmware MIUI Alternative firmware like LineageOS, Pixel Experience or ArrowOS offer cleaner Android with better optimization, and the downside is the loss of some Xiaomi chips (like Second Space or Game Turbo).

Disabling the second SIM-slot:

If you don't use the second one SIM-The module is still using energy on some models (Redmi Note 12 Pro, POCO X5) You can physically turn off the slot:

1. Turn off the phone.
2. Remove the tray for SIM-map.
3. Put the second slot on the back (carefully!).

💡

On devices with MediaTek Helio G (e.g. Redmi) 12C) Radical measures like custom firmware can cause the communication module to work in an unstable way.

If none of the methods worked, there may be a hardware problem (such as a faulty power controller or a damaged motherboard).
