How to Really Save Energy on Xiaomi Phone: Proven Techniques for 2026

Xiaomi smartphones are famous for their price-performance ratio, but even the flagship models of Redmi, POCO Mis or Mis discharge faster than you'd like, and it's not always because of a weak battery, because you're often at fault for the wrong settings, the background and the firmware. MIUI. This article is not about banal tips like “reduce brightness”, but about system optimizations that will give an increase in autonomy. 30-50% without prejudice to convenience.

We tested all the methods on models from Redmi Note 12 Xiaomi 14 Ultra -- the results were equally effective, and they focused on the hidden functions. MIUI 14/15, They're not in the standard instructions, but they have a huge impact on charge consumption, like setting up the Ultra Battery Saver mode right, and they can extend your phone by a day. 10% Disabling unnecessary sensors will save you 15% night-time.

Importantly, all recommendations are divided into three levels: for beginners, advanced users and “extreme” (with the risk of losing some functionality), choose the ones that fit your use case, starting with basic but often ignored settings.

1. MIUI Optimization: Hidden Energy Saving Settings

Firmware MIUI It contains dozens of parameters that affect autonomy, but most of them are hidden in the back of the menu. MIUI (14+) three:

• 🔋 Balanced: Standard mode with moderately limited background processes, suitable for most users.
• 🚀 Productivity – Maximum power CPU/GPU, but the battery is on 20-30% Use only for games or benchmarks.
• 🛡️ Ultra Battery Saver - An aggressive limitation of everything but basic features.Can extend performance at 5% charge by 12+ hours.

How to turn on Ultra Battery Saver correctly:

1. Go to Settings → Battery → Power mode.
2. Select Ultra Battery Saver and click Setup.
3. Manually add applications that should work in the background (for example, instant messengers).
4. Turn off Mobile Data Limitation if you use the mobile internet.

Note: This mode disables all notifications except calls and SMS. To return some functionality, add the desired applications to the exception list through Settings. → Annexes → Permits → Auto-start.

💡

If after activation of Ultra Battery Saver notifications from Telegram stopped coming, open the application manually - this will remove the lock for 5 minutes.

2. Background processes: what really eats charge

The main battery eater is not the screen or games, but the background processes that work even when the phone is idle. Xiaomi has two levels of control:

• 🔄 Auto-Run – Allows applications to start when the phone is turned on or after restarting.
• 📱 Background activity – allows applications to run in the background (for example, checking email or updating social media feeds).

How to clean the background without harming the functionality:

1. Go to Settings → Applications → Application Management.
2. Sort the list by Battery Use (click on the three dots in the upper right corner).
3. For each application from the top-10 flow-through:

Exceptions: Don’t limit Google Play Services, Miui Daemon, and system processes – this can cause disruptions.

⚠️ Note: Turning off the background for Google Play Services will cause problems with app updates and Google services. Instead, limit the background to specific apps that use Google services (such as Gmail or YouTube).

3. Screen and animation: unobvious settings

The screen is the second-largest consumer of power after the processor, but it's not just about the banal brightness, but about the hidden parameters that affect autonomy:

• 🌓 Adaptive brightness - in MIUI It's curved and often overblown. It's better to turn it off and adjust it manually.
• 🎨 Color scheme - mode AMOLED Optimized (in Settings) → Screen. → Colors) reduces battery load on 5-7%.
• ⏱️ Timeout screen - decrease with 30 second 15-20 grant +10% Autonomy with Active Use.
• 🖥️ Upgrade frequency – on models with 120 Hz (for example, POCO F5 Xiaomi 13T) 60Hz switching saves up to 20% charge.

How to adjust the screen refresh rate:

1. Open the Settings → Screen.
2. Click on the Screen Update Frequency.
3. Choose 60Hz for everyday tasks and 120Hz for gaming only.
4. Activate Adaptive Frequency if available – the system will automatically lower Hz for simple tasks.

For models with AMOLED-screens (Xiaomi 12 Pro, Redmi) K60) Extra savings are available to disable Always-On Display (AOD). This regime is expending ~1% charge per hour even in standby mode. AOD only displayed on notifications:

Settings → Always-On Display and Lock → Display Mode → Notifications Only

4.Connection and Network: How Mobile Internet and Wi-Fi Steal Charge

Communication modules (4G/5G, Wi-Fi, Bluetooth can be used up to 30% It's a charge per day if you're not optimally tuned:

• 📶 Continuous network search – if the signal is weak, the phone spends more energy on it retention.
• 🔄 Automatic switching between Wi-Fi and mobile data — MIUI Often forgets to turn off mobile Internet when connecting to Wi-Fi.
• 📡 Background data transfer – apps can download updates or media files without your knowledge.

Optimal settings for savings:

How to turn off background data transfer for specific applications:

1. Go to Settings. → SIM-maps and mobile networks → Transfer of data.
2. Click on the Background data transmission.
3. Select the apps you want to limit traffic to (like TikTok or Instagram).
4. Set a limit on mobile data and/or Wi-Fi.

⚠️ Warning: Disabling the exact location for Google Maps or Yandex.Navigator will lead to errors in the construction of routes. GPS only for background applications, leaving it for navigation.

5 Hardware Tricks: What You Can Do Without Root

Even without the super-user rights, Xiaomi has ways to optimize hardware for energy savings.

• 🔌 Turning off fast charging – if you are not in a hurry, charging on 5W instead 30W+ extends battery life and reduces heating (and therefore energy consumption for cooling).
• 🔊 Vibration when touching – disabling tactile recoil saves ~3% charge per day.
• 📸 Camera and sensors – background camera activity (e.g. for scene recognition) eats up to 12% of the charge. → Annexes → Camera. → Background activity.
• 🌡️ Approximation sensor - if it works by accident (e.g. in your pocket), the screen will not go out. Check its operation through the engineering menu (#6484##).

How to limit the maximum charge of the battery (to extend its life):

1. Activate Optimized Charging Mode in Settings → Battery → Battery settings.
2. Set a charge limit on 80-85% — This will reduce battery wear and reduce heating when charging.
3. For models that support Mi Smart Charge (such as the Xiaomi 13 Pro), enable Adaptive Charging to allow the phone to determine the optimal level.

For advanced users: if your Xiaomi supports Game Turbo, turn it off for non-gaming applications. This mode overclocks the processor even when you don’t need it, which eats up unnecessary ones. 10-15% The way:

Settings → Special features → Game Turbo → List of applications

Is the vibration off when typing?|Proximation sensor checked (#6484##)?|Is the camera's background activity limited?|Optimized charging mode is enabled?

6.Pest applications: how to find and neutralize them

Some apps are specifically programmed to maximize resource consumption, such as Chinese services, pre-installed ad units, and poorly optimized games, and here's how to calculate them:

• 🔍 Battery Monitor - Built-in tool MIUI It shows the consumption of apps over the last 24 hours. → Battery → Battery utilization.
• 📊 AccuBattery is a third-party application that analyzes discharge and shows “gluttonous” consumers.
• 🚫 Pre-installed garbage – apps like Mi Video, Mi Music, GetApps can be disabled (but not removed!) via Settings → Annexes.

Top.-5 applications that are most often to blame for discharge:

1. Facebook and Instagram are constantly sharing data with servers.
2. TikTok – Preloads videos even when you’re not watching.
3. Google Play Services – if you spend >10%, check the synchronization of accounts.
4. Miui Daemon is a system process that can leak after updates.
5. Games (PUBG, Genshin Impact – even after closing, processes are left behind.

How to remove pre-installed apps without root:

1. Download ADB Platform Tools on PC.
2. Connect your phone to your computer and activate Debugging. USB (Settings → The phone. → Version. MIUI — Press 7 times, then Settings → Additionally. → For developers).
3. Enter a command to disable an unnecessary application (for example, for Mi Music):

adb shell pm uninstall -k --user 0 com.miui.player

List of packages for popular applications:

• Mi Video: com.miui.videoplayer
• GetApps: com.xiaomi.mipicks
• Mi Browser: com.android.browser

⚠️ Note: Do not remove system applications called com.android. or com.miui. unless you are sure of their purpose.This may cause your phone to fail. Use only verified package lists for your model.

7 Extreme methods: for maximum autonomy

If you need to stay on one charge for as long as possible (like hiking or when you're out of power), use these methods. They turn off some of the functionality, but they give you up to the next. 2-3 Autonomous days even on weak models like Redmi 9A:

• ❄️ Airplane mode + Wi-Fi – Disables all radio modules except Wi-Fi. Savings: up to 40% charge.

4. Back to Settings → Battery and power Ultra Battery Saver.

In this mode, the phone will work as a “bell” with minimal functionality, but will last for 10% of the charge up to 24 hours.

💡

Combination Aircraft Mode + Wi-Fi + Black and white screen + Disabling sensors gives maximum autonomy with minimal losses in functionality.

8. Long-term tips: how to extend the life of the battery

Energy savings are not just about current charge, but also about battery health in the long run. The following tips will help keep battery capacity at 90%+ After 2 years of use:

• 🔋 Avoid full discharge – recharge your phone when 20-30%, leadlessly 0%.
• ☀️ Don’t overheat – don’t use your phone in the sun or while charging for games.
• 🔌 Use original charging – cheap cables and adapters spoil the power controller.
• 📉 Calibration of the battery - once in a while 3 Perform a full cycle of discharge / charging (0-100%) statistics-reset.
• 🔄 Updates MIUI — Newer versions often optimize power consumption (but don’t update in the first 2 weeks after release – there may be bugs).

How to check the status of the battery:

1. Enter the code in the phone app: ##4636##.
2. Select Battery Information.
3. Check the parameter Level of wear (if it is >15%, it's time to change the battery).

For models that support wireless charging (Xiaomi 13 Pro, Mix 4): Avoid constant charging at wireless stations - this heats the battery more than wired charging. Use wireless only when really necessary.

If the battery capacity fell below 80%, Xiaomi's official service centers offer a replacement for the 1500-3000 Uneconomical batteries not only discharge quickly, but can also swell, damaging the screen.
