How to save energy on Xiaomi phone: proven methods

Xiaomi smartphones are famous for their price-performance ratio, but even flagship models like Xiaomi 14 Ultra or budget Redmi Note 13 It's not always a weak battery, it's often the background, the unoptimized settings, the user's habits. This article isn't about obvious tips like "reduce brightness," but about system tricks that increase autonomy. 20-40% functionally.

We tested all the methods on the devices with MIUI 14/15 And HyperOS, but most of the recommendations are also valid for older versions of firmware, and it's important that some of the settings are hidden in the developer section or require manual editing of the settings, which we'll sort out. If your Xiaomi lives from the socket to the socket, after this article you can stretch on one charge until the evening even with active use.

🔋 Spoiler: The most effective way to save charge is to turn off background activity for apps via ADB-But more on that. First, let's look at basic settings that don't require root rights or technical skills.

1. Optimization of energy consumption in MIUI/HyperOS

Xiaomi's firmware has built-in power saving tools, but by default they don't work well. The first thing you need to do is switch the battery mode to the optimal profile.

1. Go to Settings. → Battery and productivity → Battery mode.

2. Select "Balanced" (for most users) or "Backage Saving" (if you want maximum autonomy).

3. Activate Adaptive Energy Saving – it automatically limits background processes for rarely used applications.

📌 Important nuance: In HyperOS, the battery menu looks different. Here, the way is: Settings. → Battery → Battery settings → Power saving modes. There's also a new "Super Savings" mode that turns off mobile internet for background applications -- useful when traveling.

It is also important to disable autosynchronization for unnecessary accounts:

• 🔄 Google Account: Settings → Accounts and synchronization → Google → Disable sync for unnecessary services (e.g. Google Play Movies or Google News).
• 📱 Mi Account: Only Leave Contacts and Notes if you use them. Mi Cloud sync for photos and videos eats up battery even in the background.
• ⚡ Social networks: in the settings of Facebook, Instagram and VK Turn off Background Update and Autoload Media.

⚠️ Note: If you are using Xiaomi with two SIM-And with maps, one of them can search the network in the background all the time. → SIM-maps and mobile networks → Setting up the mobile network and disabling Automatic Network Search for the second SIM, If not actively used.

2. Set up Auto Start and Background Application Activity

One of the biggest holes in Xiaomi’s autonomy is the background activity of apps. Even closed programs can wake up, update data and waste charge. MIUI There is a hidden menu where you can control it:

1. Open Settings. → Annexes → Application management → Auto-start.

2. disable autorun for all applications except messengers (WhatsApp, Telegram) and system services.

3. Go back and select Permissions → Background activity – here limit background work for games, social networks and unnecessary utilities.

🔧 For advanced users: If you want to completely block background activity for a particular application (such as TikTok or AliExpress), use the ADB-team:

adb shell cmd appops set <package_name> RUN_ANY_IN_BACKGROUND deny

To find out package_name, Install the App Inspector app from Google Play, for example, for Instagram, the command will be:

adb shell cmd appops set com.instagram.android RUN_ANY_IN_BACKGROUND deny

⚠️ Attention: After application ADB-Some apps may stop sending notifications to get it back, and to get it back, replace deny with allow in the command.

3.Screen: How to reduce consumption without losing comfort

The screen is the main energy consumer in a smartphone, but it's not always convenient to minimize the brightness or turn off the adaptive lighting.

1. Adaptive refresh rate: On flagships (Xiaomi) 13T, POCO F5) Go to Settings. → Display. → Screen refresh rate and select "Adaptive" (60-120 The system will automatically reduce the frequency to 60 Hz when watching video or reading, saving up to 15% charge.

2. Dark subject + AMOLED: If you have a smartphone with AMOLED-screen K70, Xiaomi 12 Pro, turn on the dark theme in Settings → Display. → Dark subject. Black pixels on AMOLED They are not lighted, which reduces consumption.

3. Screen waiting time: Reduce the time before the screen is turned off 15-30 Seconds in Settings → Display. → Sleeping after inactivity.

If you want maximum autonomy, turn on Read mode in the notification curtain, which turns off all animations, reduces brightness and puts the screen in monochrome mode, saving up to 25% of charge.

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

Communication modules (4G/5G, Wi-Fi, Bluetooth can be consumed up to 30% energy, if not optimized. Here's what you can do:

1. Switch to the 4G instead 5G: If you do not download large files, 5G It only drains the battery. Turn it off in Settings. → SIM-maps and mobile networks → Preferred type of network → 4G.

2. disable automatic Wi-Fi search: In Settings → Wi-Fi → Additional settings deactivate Network Search in the background and Automatic connection to open networks.

3. Use the "In the plane" mode on the subway: If the signal is weak (1-2 Dividing, the phone uses a lot of energy to find it, so turn on Flight Mode and manually activate Wi-Fi if you need to get the Internet.

📶 Hidden function: B MIUI There is an undocumented option for the forced use of one SIM-It's useful if you have two. SIM, But you only need the Internet on one:

1. Enter the dialer code ##4636##.
2. Select Phone Information.
3. Scroll down to Set your preferred network type and select SIM data-data.

⚠️ Note: If you move frequently between coverage areas (such as in suburbs), turn off Switching between 2G/3G/4G In mobile network settings, constant reconnection between standards eats up to 10% day-load.

5.Geolocation and sensors: hidden battery eaters

Geolocation services (GPS, GLONASS, Wi-Fi Positioning can drain your phone even when you're not using your cards. Here's how to fix it:

1. Turn off the exact location: C Settings → Confidentiality → Permits → Select “Approximately” instead of “Accurate” for most applications.

2. Limit access to geodata: Go to Settings → Confidentiality → Permits → Permit management → Location and disable access for unnecessary apps (e.g. Galery or Mi Video).

3. Turn off the scan. Wi-Fi/Bluetooth for geolocation: B Settings → Location → Select "Device only" mode" (GPS), shutdown.

🧭 Test: We have checked the consumption of Xiaomi 12T Pro on GPS different-scenario:

• 📍 GPS + precision-positioning: ~180 mA/h.
• 📍 Only GPS (without Wi-Fi/Bluetooth): ~90 mA/h.
• 📍 GPS switched off: ~10 mA/h (background consumption of sensors).

💡

If you use Google Maps or Yandex.Navigator, turn on the “Saving Traffic” mode in the application settings. This will reduce the frequency of updating the map and reduce the load on the processor.

6.Apps and Services: Who is to blame for the quick discharge?

Some apps drain the battery even when you're not using them.-5 "Xiaomi’s Power Thieves and How to Cut Them:

1. Social networks (Facebook, Instagram, TikTok):

- Turn off Autoplay video in the settings.

- Prohibit background activity (see Section 2).

Use Lite versions of apps (such as Facebook Lite).

💡

If your Xiaomi is draining too quickly after a firmware update, reset the cache via Settings → Memory. → Cleaning the cache. This often solves the problem of increased consumption.

8 Hardware methods: when software does not help

If all the settings are optimized, but the battery is still running down quickly, the problem may be in the hardware.

Battery status:

Install the AccuBattery app and check the battery capacity and wear.

If the capacity has fallen below 80% of the nominal, it is time to change the battery.

2. Overheating:

- Use it. CPU Monitor AIDA64, Check the temperature of the processor.

- If the phone is warmer than 45°C in simple, you may need to clean the thermal paste or replace the heat pads.

Charger:

Use the original Xiaomi power supply with Quick Charge support.

Cheap cables and adapters can cause overheating and accelerated wear of the battery.

4. Reset to factory settings:

- If the problem occurs after the update, try resetting your phone through Settings. → The phone. → Resetting settings.

- Pre-return backup through Settings → Additionally. → Backup and reset.

⚠️ If after replacing the battery, the phone began to discharge even faster, check:

• 🔌 Is the battery plume connected correctly (sometimes the masters forget to fix the connector).
• 📱 Does the new battery match the original capacity (Redmi Note 11 should be 5000 mAh, not 4500 mAh).
• ⚡ Is there a fake battery in use (check with AccuBattery – the original shows the exact capacity).
