15 ways to extend the battery charge on Xiaomi Redmi: from basic to hidden

Smartphones Xiaomi Redmi are known for their price-performance ratio, but even the most powerful models in the series - Redmi Note 12 Pro+, Redmi 10C or POCO X5 - face one problem: the battery runs out faster than we would like. Moreover, the battery is not always to blame. Most often, energy is “eaten up” by background processes, unoptimized settings MIUI and user habits that he is not even aware of.

This article is not about banal advice like “reduce the brightness of the screen.” We will look at hidden functions, as well as little-known tricks that really affect autonomy. All methods have been tested on current firmware (including system settings, hidden functions MIUI, as well as little-known tricks that really affect autonomy. All methods have been tested on current firmware (including HyperOS) and work on both flagships and budget models. Redmi. If your smartphone runs out of charge in half a day, after applying at least 5-6 tips from this guide, you will notice the difference within a day.

1. Disable "power-intensive" MIUI features that you didn't know about

Firmware MIUI (and its new version HyperOS) by default includes many services that constantly run in the background. Some of them are useful, but most are just marketing tricks that eat up the charge. For example, the function Mi-Exchange (for fast file transfer) activates Wi-Fi Direct i Bluetooth even when you are not using it.

To disable hidden battery "eaters":

• 🔍 Go to Settings → Applications → Manage applications → Three dots (⋮) → Special rights → Autostart and disable autorun for Mi Share, Mi Video, Mi Browser and other unnecessary system applications.
• 📡 In Settings → Connections → Advanced → Transfer via Wireless are using). deactivate Mi-Exchange i Fast transfer (if not used).
• 🔄 B Settings → Accounts → Mi Account → Synchronization disable synchronization of unnecessary data (for example, Notes or Calendar, if you don't use them).

Pay special attention to the function "Smart Assistant" (Settings → Accessibility → Smart Assistant). It analyzes your actions and loads data in advance - for example, it opens frequently used applications faster. It sounds convenient, but in practice this means that the smartphone is constantly doing something in the background. In tests Redmi Note 11 Pro+ disabling this function gave +12% to the operating time from batteries.

2. Setting the battery mode: which one to choose and why “Balanced” is the worst option

There are three preliminary power saving modes, but most users mistakenly choose MIUI There are three preliminary power saving modes, but most users mistakenly select Balancedconsidering it optimal. In fact, this mode simply masks real consumption without limiting background processes. Let's take a look at what to choose:

Mode	What limits	When to use	Increase in autonomy
Performance	Nothing	Only for games/benchmarks	−15% (faster discharge)
Balanced	Only screen brightness	Not recommended	±0% (no effect)
Energy saving	Background processes, CPU frequency, synchronization	Daily use	+20-30%
Ultra energy saving	Everything except calls/SMS	Critical charge (<15%)	+50% (up to 8 hours in standby mode)

How to enable the correct mode:

1. Open Settings → Battery.
2. Tap on the ⚡ icon in the upper right corner (or select Battery mode).
3. Select Energy saving and click Mode settings.
4. Activate the option Automatically turn on at 15% for Ultra energy saving.

⚠️ Attention: In Ultra energy saving mode, notifications from most applications are disabled (except for calls and SMS). To fix this, add the necessary applications (for example, WhatsApp or Telegram) to exceptions via Settings → Battery → Selecting applications.

3. Optimizing background activity: which applications drain the battery the most

Even if you do not launch an application, it can consume up to 30% charge per day through background processes. The main culprits:

• 📱 Social networks (Facebook, Instagram, TikTok) - constantly update the feed and send analytics.
• 📍 Maps (Google Maps, Yandex.Navigator) - use GPS even when closed.
• 🎮 Games (PUBG Mobile, Genshin Impact) - save cache and check for updates.
• 🔄 Cloud services (Google Drive, Mi Cloud) - synchronize files in the background.

How to limit their appetite:

1. Go to Settings → Battery → Battery usage (or Statistics in new versions).
2. Tap on an application that consumes a lot of energy.
3. Select Limit background activity and Disable autorun.
4. For extreme cases: Deep optimization (this will turn off notifications!).

Check battery consumption statistics

Add important applications (messengers) to exceptions-->

💡 Tip for gamers: If you play heavy games (Call of Duty Mobile, Genshin Impact), before When starting, turn on the mode Performance, and after exiting, return to Energy saving. This will prevent overheating and unnecessary battery consumption.

4. Setting up connections: Wi-Fi, mobile network and Bluetooth as hidden enemies of the battery

Wireless modules can eat up to 40% chargeif they are not configured correctly. For example, constant search for networks. data-i="169">in the subway or automatic Internet distribution via Wi-Fi in the subway or Internet autodistribution via Bluetooth - typical scenarios when the battery melts before our eyes.

Optimal settings:

• 📶 Mobile network: Switch to 4G only (if 5G is not needed) Settings → SIM cards and mobile networks → Preferred network type. Redmi Note 12 5G discharges 25% faster than 4G.
• 🔌 Wi-Fi: Disable Connect to open networks automatically i Search for networks in the background (Settings → Wi-Fi → Additional).
• 🔗 Bluetooth: Deactivate Search for devices and Auto-connection for unnecessary gadgets (Settings → Connected devices → Bluetooth).
• 📡 Access point: If you distribute the Internet less than once a week, disable Mobile access point in the settings completely.

Why is auto-connecting to Wi-Fi dangerous?

Many open networks (in cafes, airports) use aggressive authentication methods, forcing the phone to constantly send requests. This not only drains the battery, but also increases the risk of connecting to phishing access points.

⚠️ Attention: If you are using Mi Band or other devices Xiaomi, do not disconnect Bluetooth completely - this will disrupt the synchronization of health data. Instead, add the gadget to Settings → Battery → Select applications as an exception.

5. Screen and animation: how to reduce charge consumption by 15% without loss of comfort

The screen is the main consumer of energy in a smartphone (up to 50% of total consumption). But it's not just about brightness. Even little things like screen refresh rate (60 Hz vs 120 Hz) or animation interfaceaffect autonomy.

Optimal settings for Redmi:

• 🌓 Adaptive brightness: Disable it and set a fixed value to 40-50%. Automatic adjustment constantly uses the light sensor.
• ⚡ Refresh rate: Switch to 60 Hz (Settings → Display → Screen refresh rate). On Redmi Note 11T Pro the difference in autonomy between 60 Hz and 120 Hz is up to 3 hours.
• 🎨 Dark theme: Turn it on in Settings → Display → Dark theme. On AMOLED screens (for example, in Redmi K50) this saves up to 10% battery.
• ⏱️ Screen timeout: Set 15-30 seconds (Settings → Display → Sleep mode). Every extra minute of screen light is −1% of the battery per hour.

For advanced users: disable interface animation. This will not only speed up your smartphone, but also save battery. To do this:

1. Activate Developer mode (tap on MIUI version 7 times to Settings → About phone).
2. Go to Settings → Advanced → For developers.
3. Install Window animation scale, Transition animation scale and Animator duration on Off.

6. Hidden MIUI functions for advanced users. users

In MIUI i HyperOS there are hidden tools that are not advertised, but seriously affect autonomy. For example, the function Ultra energy saving (not to be confused with the standard mode!) can extend the life of the smartphone by 50% due to aggressively limiting the background processes.

How to activate hidden chips:

• 🔋 Ultra energy saving: Enter the code Phone code ##4636##, select Battery information and enable the option. ⚠️ Attention: This will turn off notifications from all applications except calls!
• 🛠️ MIUI optimization: Go to Settings → About phone → All settings → System optimization and run the process. This will clear the cache and restart system services.
• 🔄 Reset the battery adapter: If your smartphone suddenly begins to discharge faster, reset the calibration data: Settings → Battery → Three dots (⋮) → Reset the battery adapter.

Another little-known trick - disabling the second symbol slotif you do not use it, even an inactive SIM card spends energy searching for a network. To deactivate it:

1. Go to Settings → SIM cards and mobile networks.
2. Select an unused SIM and disable it.
3. In the same menu deactivate Auto network search for this card.

7. Applications for monitoring and automatic optimization

If manual settings seem complicated, use specialized utilities They analyze battery consumption and offer optimizations in one click. for Redmi:

Application	Functions	Link (Google Play)	Free?
AccuBattery	Battery health monitoring, consumption analysis by application, charging recommendations	com.digibites.accubattery	Yes (with adverts)
Greenify	Forced hibernation of background applications (requires root or ADB)	com.oasisfeng.greenify	Conditional
Battery Guru	Tracking charge cycles, battery temperature, overheating notifications	com.paginas.batteryguru	Yes
MIUI Battery Optimizer	Automatic application of hidden MIUI settings to save battery	Not in the Play Market (download from 4PDA)	Yes

⚠️ Attention: Applications like Greenify require additional permissions (for example, ADB). Incorrect use can lead to malfunctions of the smartphone. If you are not sure, limit yourself to AccuBattery or built-in tools MIUI.

For those who are ready to dive deeper, there is a way to disable unnecessary system services. via ADB. For example, the command below disables background synchronization Mi Cloud:

adb shell pm disable-user --user 0 com.miui.cloudservice

But remember: this may interfere with the operation of some functions (for example, backup).

8. Correct charging: how to extend battery life by 30%

Even if you have optimized everything settings, incorrect charging can reduce the battery life by 2-3 times. Lithium batteries degrade due to overheating, deep discharge and constant maintenance of 100% charge. Charging rules that actually work: Redmi degrade due to overheating, deep discharge and constant maintenance of 100% charge.

Charging rules that really work:

• 🔌 Use the original charger. Fast charging (33W/67W) convenient, but heats up the battery. For daily use, it is better to charge with a standard adapter (10W-18W).
• 📉 Not. Discharge below 20%. Deep discharge (<5%) destroys the battery structure. Set the low charge notification to 25% in AccuBattery.
• ⚡ Do not keep it on charge all night. After 100%, the battery continues to be recharged by microcurrents, which increases wear. Turn off charging when it reaches 80-90%.
• 🌡️ Avoid overheating. Do not play games while charging and do not place the phone in direct sunlight. rays. The optimal temperature for lithium batteries is 10-35°C.

Myths about charging that you should not believe

❌ “You need to completely discharge the battery once a month” - this was true for nickel batteries. 20 years ago.

❌ "Charging from a Power Bank harms the battery" - no, if it is a high-quality battery with PD/QC support.

❌ "Wireless charging is safer" - on the contrary, it heats up the battery more than a wired one.

💡 Travel tip: If you leave the phone unused for a long time (for example, on a trip), charge it to 50% and turn it off. Storing at 0% or 100% accelerates degradation.

FAQ: Answers to frequently asked questions

Is it possible to disable MIUI Optimization? to save battery?

Function MIUI Optimization (in Settings → Advanced → Accessibility) is responsible for the smoothness of animations and background processes. Disabling it will give + 5-7% autonomy, but can lead to interface lags. We recommend leaving it enabled and instead limiting the background activity of specific applications (see section). 3).

Why does the battery drain quickly even in standby mode?

The culprits are background processes and Wake Locks (the mechanism that prevents the processor from falling asleep? Check the statistics). c Settings → Battery → Usage batteries. If you see an application with high consumption in the background (for example, Facebook or Mi Video), limit its activity or delete it. Also, the reason may be a poor network signal - the phone is wasting energy searching for a connection.

How to check the health of the battery on Redmi?

There are two ways:

1. Via code: enter in the application Phone ##4636##, select Battery information and look at the parameter Level wear.
2. Through AccuBattery: after 2-3 charging cycles, the application will show the actual battery capacity and degree of degradation.

Normal wear - up to 15% for 1-2 years of use. If the value is above 25%, it’s time to think about replacing the battery.

Do “magic” battery saving applications from the Play Market help?

Most applications like Battery Doctor or DU Battery Saver not only do not help, but can also do harm. They:

• Forcibly close background processes, which leads to their restart (and additional energy consumption).
• Show aggressive advertising, which itself drains the battery.
• They may contain malicious code (especially if downloaded not from the official store).

Use only proven utilities from our list (section 7).

Should I turn off GPS if I don’t use it?

Yes, but with reservations. Completely turning off GPS (Settings → Security → Location) will save up to 5% of charge per day. However, many applications (for example, Google Maps or Yandex.Weather) will perform worse or refuse to start at all. An alternative is to restrict access to the location for unnecessary applications manually:

1. Go to Settings → Privacy → Permissions → Location.
2. Disable access for all applications except navigators and maps.
3. For Google Play Services set the permission Only during use.
