How to Save Battery on Xiaomi: A Complete 2026 Guide

Xiaomi smartphones are some of the most popular on the market due to the ratio of price and functionality, but owners often face rapid battery discharge. The reason is not always a “weak” battery: MIUI (branded shell) actively consumes resources in the background, and the default optimization is designed for the “average” user. In this article, we will analyze 15 working ways to save charge without compromising convenience – from hidden settings to hardware life hacks.

It's important to understand: Redmi, POCO and flagship series (Xiaomi) 13/14) So, for example, budget models suffer from weak processors that warm up and put the battery down faster, and top models suffer from excessive background processes. 2020–2026 year-end.

Spoiler: Some methods will increase autonomy by 30-50% (based on the Redmi Note 12 Pro+ and POCO F5), but will require sacrifices, such as disabling widgets or limiting application updates. Ready to optimize? Let's start with the most effective.

1. MIUI Optimization: Hidden Energy Saving Settings

MIUI Energy Saver is an integrated tool that many users ignore, and it works at the core level, and it can block background activity even for system processes.

Go to Settings → Battery and Performance → Energy Saving Mode.
Select Ultra Mode (on some models - Super Mode).
Enable the option to limit the background for all applications.

⚠️ Attention: Ultra-mode disables push notifications for messengers (WhatsApp, Telegram). To fix this, add the desired applications to the Exceptions (Battery Optimization section).

What is Deep Optimization in MIUI?

It's a feature that forces all background processes to close when you lock the screen. +15-20% autonomy, but can cause delays when unlocking (up to 2-3 seconds). → Special facilities → Deep Optimization (not available on all models).

Another secret trick is to turn off the MIUI animation, which not only slows down the interface, but also wastes a lot of energy on re-drawing the screens.

Settings → About Phone → MIUI version (shap 5 times to turn on Developer Mode)


Settings → Additional → For developers → The scale of the animation window / transition / animator (set 0.5x or turn off)

💡

If after disabling the animation interface began to "twitch", return the value to 0.5x - this is a compromise between smoothness and saving charge.

2. Set up Auto Start and Background Application Activity

By default, MIUI allows all apps to autorun, even those you don't use, which is one of the main reasons for quick discharge.

📱 Go to Settings. → Annexes → Application management → Auto-start.
🔍 Sort the list by date of last use.
❌ Turn off auto-run for all applications except instant messengers and banking services.
🔄 In the same menu, open the Background Activity and limit it for games and social networks.

Pay special attention to Google Play Services, which can consume up to 15% of its charge per day, to reduce its appetite:

Open Settings → Google → Google Account → Account Sync.
Turn off sync for unnecessary services (like Google Fit or Google News).
Go back to Settings → Apps, find Google Play Services and limit background activity.

3.Screen: brightness, refresh rate and Always On Display

The screen is the main charge eater, even on the AMOLED-panels (installed in Xiaomi) 13T, POCO F5 Pro) Incorrect settings can reduce the time of operation by 30:

☀️ Set adaptive brightness to 60-70% (manual). Automatic adjustment often overstates the values.
🌙 Enable Dark Theme (in Settings) → Display - on AMOLED This saves up to 25 percent of the charge.
🔄 Turn off Always On Display (if any).This feature spends up to 5% of charge per hour on standby.

The flagships (Xiaomi 14, Redmi K60) have a 120Hz screen, and the high refresh rate is useful for gaming, but in everyday tasks (messengers, browser) it only lands the battery.

Mode of use	Recommended frequency	Saving charge
Normal use	60 Hz	20%
Watching video	90 Hz	10%
Games	120 Hz	0%
Reading (browser, books)	30 Hz (if supported)	30%

⚠️ Note: On some models (POCO X5, Redmi Note 11) Forced frequency reduction to 60 Hz can cause artifacts in games.In this case, use Adaptive frequency in screen settings.

4. Communications: 5G, Wi-Fi, Bluetooth and GPS

Communications are the second largest consumer of power after the screen. 5G-The modem can use up to 10 percent of the charge per hour:

📶 Turn it off. 5G, if you are not in coverage or using high-speed internet. → SIM-maps and mobile networks → Network type and select 4G/3G/2G.
📡 Enable Adaptive Wi-Fi (in Settings) → Wi-Fi → This turns off the module when the screen is off.
📍 For Google Maps or Navigators, use the Charge Saving Mode in the App Settings.
🔵 Turn off Bluetooth and NFC, When they are not needed (even in the background they spend) ~3% charge per day).

If you lose your network frequently (e.g., in the subway or outside the city), turn on Airplane Mode for that time, and constantly searching for the network puts the battery down more than the communication module itself.

5G disabled (if not needed)

Battery: calibration, charging cycles and temperature

Lithium polymer batteries (installed in all modern Xiaomi) degrade over time, but properly handled can extend their lifespan by 20 to 30 percent.

🔋 Avoid full discharge (below 10%) and recharge (above 90%.
❄️ Do not use your phone in temperatures below -10°C or higher +40°C. Storing a discharged phone in the cold can irrevocably damage the battery.
🔄 Every 3 months, complete a full charge cycle (0–100%) to calibrate the controller.
🔌 Use only original or certified chargers. Cheap adapters can damage the battery.

If the phone began to quickly discharge "on the level", check the wear of the battery:

Enter the phone app code ##4636##.
Go to Battery Information.
Look at the wear-and-wear (or Health) parameter, if it's above 20%, it's time to change the battery.

💡

Charging to 100% and storing a phone with a full battery accelerates battery degradation by 2 times.If you leave your phone overnight, disconnect it from charging when you reach 80%.

6.Apps and Games: What Really Lands a Battery

Some apps consume power in non-obvious ways, like TikTok in the background can download cache videos, and Facebook can update the feed every 5 minutes, and we'll figure out how to fix that.

Top.-5 "Xiaomi’s “gluttonous” apps (according to AccuBattery):

TikTok – up to 18% charge per hour (due to background video downloads).
Instagram – 12% (constant synchronization of stories)
Google Chrome – 10% (background tabs)
MIUI System – 8% (optimization and analytics)
WhatsApp – 6% (constant activity for push notifications)

How to reduce consumption:

🎮 For games: Enable Game Mode in the Notification Curtain – it limits background processes.
📺 For video: Use YouTube Vanced or NewPipe – they block background playback.
🛒 For social networks: disable Autoplay video in the application settings.
🔄 For all applications: limit Background activity in Settings → Annexes.

⚠️ Note: Some of the “battery optimizers” from Google Play (e.g., Google Play, DU Battery Saver, which is the cause of the increased consumption, they work on the principle of antivirus-pacifiers, creating background processes. Use only built-in tools. MIUI.

7 Hardware life hacks: what to do if software methods do not help

If you've tried all the settings, but the battery still goes down in half a day, the problem could be the hardware.

🔍 Battery wear: how to check, we told in section 5. If the wear is above 30%, the battery should be replaced.
🔌 Charging port: oxidized contacts or backlash connector can cause overheating and increased consumption.
📡 Antenna: If the phone is constantly losing network, the communication module is running at the power limit.
🔥 Overheating: If the case is hot even in a simple one, it is a sign of a processor or battery malfunction.

If you decide to replace the battery, only use the original (branded Xiaomi or ATL).

🔥 ignite when charging.
📉 Have real capacity 20-30% less than the declared.
🔋 Degrade quickly (wear and tear 50% in 6 months).

To replace the battery in Xiaomi does not have to go to the service center. On models with a removable back cover (Redmi 9A, POCO M3) you can do this yourself, following the guide:

1. Turn off the phone and remove the SIM- card.


2. Tap the back cover with a plastic spatula (start at the corner near the camera).




3 Unscrew 5 screws (cross screwdriver PH00).




4. Disconnect the battery plume and remove it.




5. Install a new battery and assemble the phone in reverse order.

💡

Before replacing the battery, discharge the phone to 20-30%, which will reduce the risk of short circuit when the plume is disconnected.

8. Alternative methods: from root rights to custom firmware

If you are willing to take drastic measures, consider:

🔓 Root rights: You can disable unnecessary system services (e.g, MIUI Analytics, but this will void the warranty.
📱 LineageOS or Pixel Experience are devoid of a “heavy” shell MIUI give +20-40% autonomy.
⚡ Cores with optimization: for example, FrancoKernel for POCO F1 Or Perseus for Xiaomi Mi 9.

⚠️ Note: Installation of custom firmware requires unlocking the bootloader, which:

Drops all the data on the phone.
It can lead to a “brick” (inoperability) in case of an error.
You will be deprived of official MIUI updates.

If you’re a beginner, start with more secure methods — like disabling bloatware (pre-installed apps) through ADB:

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


adb shell pm uninstall -k --user 0 com.xiaomi.midrop




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

This will remove unnecessary system applications without root rights.

FAQ: Frequent questions about battery saving on Xiaomi

🔋 Why the battery goes down quickly even after resetting?

The problem is probably battery wear (see section 5). Lithium polymer batteries lose capacity after 300 to 500 charge cycles. Also check if the phone is warming up - overheating accelerates discharge.

📱 How to turn off advertising in MIUI? She's planting the battery, too?

Yes, background banner loading consumes up to 5% of the charge per day. To disable: Go to Settings → Memory → Cleanup. Turn off Recommendations and Personalized Services. In Settings → Xiaomi Account → Synchronization, disable msa (mi-services).

⚡ Can you use powerbank to save money?

Indirectly, yes. If you plug your phone into a powerbank before the battery runs below 20 percent, it reduces battery wear, but the powerbank itself doesn't affect charge consumption.

🔌 Why does the phone run out at night if it’s turned off?

This is normal: even in the off state, it is consumed. ~1-2% charge per day to maintain time and memory, if the discharge is more than 5% per night, check the power button (possibly the phone wakes up from random presses) or remove SIM-card (a defective module can drain the battery).

📊 Which app is best for monitoring the battery?

We recommend AccuBattery (free version is sufficient). It shows: Real battery capacity (adjusted for wear), charge consumption by application, battery temperature, charging/discharge speed, avoid "optimizers" like Battery Doctor - they themselves cause increased consumption.
