How to completely turn off energy savings on Xiaomi Redmi 9: 5 proven ways

The power saving mode on Xiaomi Redmi 9 smartphones is a two-way sword: on the one hand, it prolongs battery life, and on the other hand, it limits performance, turns off background processes and can even block notifications. If your phone has started to “brake”, applications do not update in the background, and battery power drops too quickly despite all restrictions – it’s time to figure out how to turn off energy savings correctly.

Many users have a problem when the settings are reset after the MIUI update and the saving mode is activated automatically. In addition, Redmi 9 has several levels of energy saving (including “super-saving” and “ultra-mode”) that work in different ways. In this article, we will not only show how to remove all restrictions, but also explain what functions are turned off while doing this, and how to avoid rapid battery drain after deactivation of the mode.

It is worth noting that on Redmi 9 (M2003J15SS, M2004J19C) the process may vary depending on the version of MIUI (12, 13 or 14) and regional firmware. If you use custom firmware (for example, Pixel Experience or LineageOS), some menu items may be missing or called differently.

1. Standard method: through battery settings

The most obvious and safe method is to disable the power savings through the main menu, which works on all versions of MIUI, but may require additional action if the system has blocked some settings.

Open the Settings app (the gear icon on the home screen) and go to Battery and Performance. Here you are interested in two sub-items:

1. Battery mode – responsible for the overall energy saving settings;
2. Battery usage – shows which applications consume the most charge.

In Battery Mode, you'll see the Battery Savings switch that can be turned on automatically when the charge level is below 15-20% by default. On Redmi 9 with MIUI 14, you can manually change this threshold by tapping the gear icon in the upper right corner.

To turn off the mode completely, move the slider to the "Off" position. The system can issue a warning about reducing battery life - confirm the action. If the option is inactive (gray), then the phone is on ultra-saving mode - it needs to be turned off separately (more on this below).

2. disabling ultra-battery saving mode (Ultra Battery Saver)

Redmi 9 has a hidden Ultra Battery Saver feature that activates at a critical charge level (usually 5-10%) or manually, in which the phone blocks almost all background processes, turns off mobile Internet for most applications, and can even reduce the brightness of the screen to a minimum.

To deactivate the ultramode:

1. Open Settings → Battery and Performance → Battery Mode
2. Scroll down and find the Ultra-Economies item (or Ultra Battery Saver in English firmware).
3. Slip it on it and select "Disable".
4. If the option is inactive, plug your phone into charging – some versions of MIUI block changes when charged low.

If the ultramode is on automatically and doesn't turn off via the menu, try rebooting your phone. Sometimes this helps to reset the time limit. Also check if Auto Ultra Economy is activated in the battery mode settings - you need to turn it off separately.

💡

If you turn off ultramode, the applications still don't work in the background, check the autostart settings: Settings → Applications → Application Management → Autorun. Many programs require manual permission to run in the background.

3. Hidden Settings: Disabling Savings for Individual Applications

Even if you turn off the general saving mode, MIUI can continue to restrict individual applications, including messengers (WhatsApp, Telegram), social networks (Instagram, TikTok) and geolocation services (Google Maps, Yandex.Maps), to remove restrictions:

Step 1. Go to Settings → Applications → Application Management and select the desired application (e.g. Telegram).

Step 2. Tap on the item "Battery use".

Step 3. In the menu that opens, select "No restrictions" (or No restrictions) to allow the application to work in the background without locking.

For convenience, you can use group management:

• 📱 List of applications: Open Settings → Battery → Battery usage and tap the filter icon (top right) and sort programs by consumption.
• ⚡ Optimize: In the same section, find the Optimize button to show you which applications can be free of restrictions.
• 🔄 AutoRun: Some programs (such as Viber) require additional autoruption permission, otherwise they won’t work in the background.

4.Use ADB to completely disable savings (for advanced)

If standard methods don’t work, and MIUI persists in returning savings settings after rebooting, you can use USB debugging (ADB), which is suitable for advanced users and requires connecting the phone to a computer.

Step 1. Enable the developer mode on Redmi 9:

• Go to Settings. → The phone.
• Tap 7 times on the MIUI version until the notification “You became a developer!” appears.
• Go back to the basic settings and open a new section for developers.
• Activate Debugging on USB.

Step 2. Connect the phone to the PC, install ADB-Drivers and execute in the command line:

adb shell dumpsys deviceidle force-idle


adb shell settings put global low_power_mode 0

These commands force the system-level power-saving modes to be turned off. Attention: after that, some MIUI functions (e.g., automatic optimization) may not work properly.

adb shell settings put global low_power_mode 1

5. Consequences of power saving off

Before you deactivate energy savings completely, you should evaluate where that's going to go, and here are the major changes you'll notice.

The power outage will be particularly severe for the Redmi 9 with a worn-out battery (capacity below 80%), in which case the phone can run at 5-7% per hour even in standby mode. If you are critical of battery life, consider alternative optimizations:

• 🔋 Battery replacement: Original battery for Redmi 9 (model) BM4X) It costs about 1,500 to 2,000. ₽. After replacement, autonomy will return to factory performance.
• ⚡ Adaptive brightness: Include in Settings → Display. → Adaptive brightness – this saves 10-15% charge without losing convenience.
• 📵 Mobile Data Limitation: Disable background traffic for unnecessary apps in Settings → SIM-maps and mobile networks → Transfer of data.

💡

Turning off energy savings is only advisable if you are willing to sacrifice autonomy for performance, and for most users, the best option is to selectively disable restrictions for key applications (messengers, navigators).

6. Frequent mistakes and how to avoid them

Many users experience problems after turning off energy savings, and here are the most common mistakes and ways to solve them:

Problem 1: After the power out, the phone started to warm up a lot.

⚠️ Note: If the processor temperature exceeds 50°C in plain, this may indicate a battery or thermal paste malfunction. Check charging in the AccuBattery app (available on Google Play). If the capacity has dropped below 70%, the battery needs to be replaced.

Issue 2: Apps are still not updated in the background.

Solution: In addition to turning off savings, check:

• Auto-Run Authorization (see Section 3).
• Battery optimization settings in Settings → Special features → Battery optimization.
• Restrictions on mobile data in the background (SIM-cards section and mobile networks).

Problem 3: The saving mode is activated after the reboot.

This is typical of MIUI 12 and earlier.

1. Update your firmware to the latest version (preferably MIUI 14).
2. Use it. ADB-Commands (Section 4) for forced shutdown.
3. Check if you have installed third-party battery saving software (such as Greenify or Battery Doctor).

💡

If you still activate the energy savings after all the manipulations, try resetting your phone to factory settings (Settings → About Phone → Resetting).

7. Alternatives to a complete cut-off of savings

If you want your phone to run faster but not run out in half a day, try a compromise setting.

Option 1: Adaptive Battery (Adaptive Battery)

MIUI 13/14 has an Adaptive Battery feature that analyzes your habits and optimizes your energy consumption without any stringent restrictions.

1. Go to Settings → Battery and Performance → Battery Mode.
2. Select "Adaptive Battery".
3. Give the system 2-3 days to learn – after that, the background processes will be blocked selectively.

Option 2: Manual control of background processes

Instead of turning off the savings completely, you can manually allow work in the background only for the desired applications:

• 📲 For instant messengers: WhatsApp, Telegram, Viber – install without restrictions.
• 🗺️ For navigators: Google Maps, Yandex.Navigator – Allow Exact Location and Background Activity.
• 🎵 For music: Spotify, Yandex.Music - turn on AutoRun.

Option 3: Use of the “Productivity” mode

MIUI has a hidden Performance mode that disables most of the constraints, but doesn't consume as much as it does with total power cuts.

1. Open Settings → Battery and Performance → Battery Mode
2. Select “High Performance” (Can be called High Performance).
3. Confirm the choice - the phone will restart.
